Sleeping on your side is considered to be the most common sleeping position. Side sleeping also has major benefits including reduced back pain, improved breathing, and better digestion. However, side sleepers often experience shoulder pain and lower back pain if their mattress is unsupportive or uncomfortable. The type of mattress you sleep on directly affects how much support and comfort you get each night.

Side sleepers often prefer a mattress that contours to the shape of the body and provides pressure point relief. These features reduce back and shoulder pain while cushioning the areas of the body that press deeper into the mattress. We’ve tested scores of mattresses, analyzing how each performs for side sleepers across a variety of weight groups. Our testers also examined each mattress for criteria like durability, temperature neutrality, and value.

Many mattresses are constructed with materials that make them comfortable for side sleeping, but the Helix Midnight is one of the only mattresses on the market that is designed specifically with these sleepers in mind. If you frequently switch between your right and left sides while you sleep due to shoulder pain or stiffness, the Midnight provides enough give to ensure you’ll be comfortable staying in one position.

What It’s Made of

The breathable cover of the Helix mattress increases airflow throughout the mattress and prevents heat retention. A layer of Memory Plus foam relieves undue pressure on the shoulders and hips, while a second layer of high-grade polyfoam offers ergonomic support and cushion in these areas.

Individually wrapped coils in the support base minimize motion transfer and circulate air. This layer gently contours to the shape of your body. A bottom layer of DuraDense foam enhances the support and durability of the Helix mattress.

How It Performed

The Helix Midnight mattress has a medium firm feel with impressive pressure point relief. The Memory Plus foam contours closely to the body, cushioning high-impact areas and preventing aches and pains. The foam layers of the Helix Midnight mattress have different densities in order to provide the best relief and support for side sleepers.

Edge support is another area where the Midnight performs well. The coil base has a reinforced perimeter, which increases the sleepable surface area of the bed and prevents sagging along the perimeter.

Helix gives you 100 nights to try out the Midnight mattress, with a 30-day break-in period. The mattress is covered by a 10-year warranty, though the customer is responsible for shipping costs. In the event of a defect, Helix will reimburse up to $100 in shipping charges.

Lab Notes – What Our Testers Thought

“We found the Midnight to be a great choice for side sleepers who need more support. The memory foam provides just enough cushioning and the coils make the mattress feel really stable.”

The Nectar is a high-quality memory foam mattress with an approachable price-point. This makes it suitable for buyers on a budget and high-end shoppers alike.

What It’s Made of

The Nectar begins with a gel-infused memory foam comfort layer, followed by transitional and support layers of dense polyfoam. A cover made of polyester, nylon, and polyethylene encases the entire mattress. The Nectar is considered medium firm (6) and measures 11 inches thick, making it a middle-of-the-road mattress in terms of both firmness and profile.

How It Performed

The cover of the Nectar wicks away moisture, while the gel-infused memory foam distributes body heat and weight. A transitional polyfoam layer offers additional support and prevents uncomfortable sinking. A polyfoam base layer stabilizes the mattress. The foam layers result in top-notch motion isolation and pressure point relief.

The Nectar offers a very balanced sleep experience. A thick memory foam comfort layer contours to the body and cradles the spine, but a medium firm feel and sturdy support layers prevent excessive hugging or sinkage. As a result, the Nectar should feel quite comfortable for anyone who sleeps on their side and enjoys the cloud-like feel of sleeping “in” – rather than sleeping “on” – their mattress.

Since the Nectar is medium firm, it is best for people who weigh more than 130 pounds. With contouring foam that doesn’t sink in too deeply, the mattress has good air circulation and does not retain heat.

Nectar offers a generous 365-night sleep trial, giving you a full year to try out the mattress. The mattress is also covered by a lifetime warranty. For the first 10 years, Nectar will replace a defective mattress at no cost. After the first 10 years, they will repair or replace the mattress with a $50 shipping charge each way. This charge is waived if the mattress has a defect.

Lab Notes – What Our Testers Thought

“The Nectar feels firmer and more supportive than many of the memory foam mattresses we’ve tested. I get to enjoy the slow response and close contour without the uncomfortable sink.”

The DreamCloud is a foam hybrid foam mattress that excels across various performance categories. The strong balance of contouring and support makes this a suitable choice for many types of sleepers.

What It’s Made of

The mattress begins with a breathable cashmere blend cover that’s been quilted with polyfoam for a soft, plush surface. Beneath is a layer of memory foam that provides close contouring to the body. The memory foam is infused with cooling gel meant to minimize the trapping of body heat. A transition layer made with polyfoam provides moderate contouring but is firm enough to prevent the body from sinking too deep. The support core contains a coil system with a pocketed design intended to reduce motion transfer.

How It Performed

Rated medium firm (6), the DreamCloud offers adequate cushion to areas where pressure tends to build up during sleep, such as the shoulders and hips. Meanwhile the polyfoam and coil system provide enough support for sleepers who require some firmness. Though the memory foam may run too warm for some sleepers, the coils should enable enough air circulation to prevent excessive overheating.

DreamCloud ships mattresses for free within the contiguous U.S. The company offers a generous lifetime warranty and 365-night sleep trial, with a 30-day break-in period required.

Lab Notes – What Our Testers Thought
“As a side sleeper, I enjoyed the combination of thick foam cushioning and good overall stability. The DreamCloud’s thick design definitely gives it an edge over a lot of lower-profile mattresses.”

Saatva Classic

10% off sitewide & 15% off orders over $2,750

Side sleepers generally don’t feel comfortable on innersprings compared to other mattress types because most contain thin foam layers that offer little to no cushioning for the shoulders, lower back, and hips. These areas are all susceptible to added pressure if you sleep on your side without sufficient padding.

The Saatva Classic is unlike traditional innersprings. This coil-on-coil mattress is available in three firmness levels, including a soft (3) option for side sleepers who weigh less than 130 pounds and a medium firm (6) for those who weigh more. If you sleep on your side and need extra support, you can opt for a firm (8) feel instead.

What It’s Made of

The mattress features a Euro-top containing foam and soft fibers to give the surface a plush, comfortable feel. A transitional layer of pocketed minicoils and a support core with sturdy, recycled-steel hourglass coils deliver excellent support regardless of which firmness level you choose. You can also select a profile of 11.5 inches with 4-inch base coils or 14.5 inches with 7-inch base coils, the latter offering more reinforcement and bounciness on the surface.

How It Performed

The dual coil layers reinforce the perimeter to prevent excessive sinkage when you sleep near the edges or get on and off of the mattress. These layers also circulate air throughout the interior to keep the mattress cool, while a breathable organic cotton cover wicks away moisture from your body. Even by innerspring standards, the Saatva Classic sleeps exceptionally cool.

Saatva is one of the only online mattress brands to provide free White Glove delivery throughout the contiguous U.S. This service includes scheduled delivery date and time, full mattress assembly in a room of your choosing, and complimentary haul-away for your old mattress and box spring. Each purchase comes with a 180-night sleep trial for testing out the Saatva Classic and deciding whether it’s right for you, as well as a 15-year warranty for those who keep the mattress.

Lab Notes – What Our Testers Thought

“The Saatva Classic is one of the most supportive mattresses we tested, but the Euro-top prevents the surface from feeling too stiff. The medium firm feel was the most popular with our testing group.”

Firmness options can be beneficial for any side sleeper who isn’t sure which type of mattress will provide the right balance of cushioning and support. The Brooklyn Bedding Signature Hybrid is available in three distinct firmness levels. This ensures most side sleepers can find a comfortable option regardless of how much they weigh – and thanks to Brooklyn Bedding’s exchange policy, any customer can trade in the mattress they initially choose if it feels too firm or too soft.

What It’s Made of

The Signature Hybrid is constructed with a comfort layer of TitanFlex polyfoam and a transitional layer of VariFlex foam. The latter has a latex-like quality that makes it feel responsive and springy, while the TitanFlex contours more closely. The firm (8) feel features more transitional foam and a thinner comfort layer, while the medium soft (4) and medium firm (6) feels have more TitanFlex foam.

All Signature Hybrid models are equipped with pocketed coils and base layers of high-density polyfoam. These components stabilize the mattress to maintain an even sleep surface. The coils are also reinforced along the perimeter to minimize sinkage when owners get out of bed or sleep near the mattress edges. A knit cover completes the design.

How It Performed

Each firmness level for the Signature Hybrid performed well in a few areas. The medium soft models feel quite plush on the surface, making this option best-suited to side sleepers who want deep cushioning for the shoulders and hips. We also found that this feel provided the best motion isolation. The medium firm feel is more supportive and probably a better fit for side sleepers who weigh between 130 and 230 pounds. Lastly, the firm feel barely contours at all and is quite stable. Those who weigh more than 230 pounds will likely prefer this firmness level.

There were a few areas where the Signature Hybrid performed well regardless of firmness level. These included temperature control, edge support, and ease of movement.

Customers can select from several sizes for their Signature Hybrid. In addition to the six standard mattress sizes, you can choose an Olympic queen, split California king, or a handful of short and RV-friendly sizes. Shipping is free throughout the contiguous U.S., and each purchase is backed by a 120-night sleep trial and a 10-year warranty.

Lab Notes – What Our Testers Thought
“I preferred the medium firm feel, but each of our testers found at least one firmness for the Signature that felt comfortable and supportive enough. We expect the mattress to be popular with hot sleepers, too.”

Birch Mattress

SleepFoundation readers get $400 off a Birch Mattress.

The Birch Mattress is a latex hybrid featuring an assortment of natural and eco-friendly components. These materials make it a good option for side sleepers seeking a supportive, pressure-relieving mattress that’s also sustainably produced.

What It’s Made of

The Birch Mattress is constructed with an organic cotton cover, eco-friendly wool batting, and a comfort layer of natural Talalay latex. The bed is medium firm (6) and offers a responsive feel due to the combination of springiness from the bed’s pocketed coil support layer and the bounce of the minimally conforming latex comfort layer.

How It Performed

The bed’s coils are zoned to provide reinforced edges, which enables sleepers to utilize the entire surface of the bed. The robust support core provides ample support for side sleepers weighing 130 pounds or more, while the wool and latex comfort layers offer just the right amount of contouring to relieve pressure points.

Lighter sleepers will experience more of a floating sensation and the bed may feel a bit firmer for them, so depending on personal preferences, lighter sleepers may prefer a model with more cushioning for the shoulders and hips.

Birch offers free shipping to customers within the U.S. and backs the mattress with a 100-night sleep trial and a 25-year warranty.

Lab Notes – What Our Testers Thought

“We think the Birch will be a good alternative for side sleepers who need cushioning around their lower back and hips, but don’t like how memory foam sinks beneath their weight. Most of us agreed the latex provides just the right amount of give.”

WinkBed

Get $300 off all beds + $399 in bedding accessories (a $699 total value)

The WinkBed is a standout hybrid available in a wide range of firmness levels. This selection allows the mattress to cushion the shoulders and hips, promote proper spinal alignment and reduce back pain for virtually any side sleeper regardless of their body type. The mattress is available in Soft, Medium, Firm, and Plus models, which translate to a medium soft (4), medium firm (6), firm (7), and firm (8) on the 10-point firmness scale.

What It’s Made of

Each WinkBed model follows the same basic construction with slight variations. The mattress is wrapped in a breathable Tencel cover, with two layers of gel-infused polyfoam quilted into a Euro top in the base models. The polyfoam provides some cushioning and contouring to relieve pressure, while the gel infusion helps draw excess heat away from the sleeper.

Next is a layer of micro-coils. These coils are individually wrapped, allowing them to move independently of each other to accommodate different parts of the body and reduce the likelihood of motion transferring from one side of the bed to the other. The medium soft model has an additional layer of transitional polyfoam acting as a buffer to keep sleepers from sinking into the bed’s core. The Plus model uses durable, zoned latex in place of micro-coils to provide targeted support and cushioning throughout the bed.

The WinkBed’s support core consists of a base of zoned, individually wrapped coils. The zones vary depending on the model, providing extra support under heavier areas and a more accommodating feel for lighter ones. The perimeter of the bed is reinforced, providing standout support around the edges and increasing the usable surface of the mattress.

How It Performed

The WinkBed’s multiple firmness options ensure that there is a comfortable, supportive bed for any side sleeper. Those who weigh less than 130 pounds will fare best on the ample cushioning of the medium soft or medium firm options. Sleepers who weigh between 130 and 230 pounds will be most comfortable on either the medium firm or firm models. Lastly people who weigh more than 230 pounds tend to gravitate toward the support and firmness of the firm and Plus options.

The WinkBed ships free to the contiguous U.S. The mattress is backed by a 120-night sleep trial that has a 30-night adjustment period before you can initiate a return. It is also covered by a lifetime warranty.

Lab Notes – What Our Testers Thought

“Coil-on-coil models like the WinkBed provide a level of support you won’t find in most standard hybrids. We expect that side sleepers who weigh 130 pounds or more will really enjoy this one.”

Casper Original Hybrid

Save 10% off your cart with code SF10

Many hybrid models don’t offer enough cushioning or contouring to alleviate pressure for side sleepers, but the Casper Original Hybrid is a notable exception. A medium feel and adaptive foam layers ensure above-average pressure relief compared to other coil mattresses.

What It’s Made of

The mattress is considered medium (5) and constructed with a top layer of adaptive AirScape polyfoam that conforms to the body without hugging too tightly. The transitional layer is composed of memory foam divided into three firmness zones, resulting in extra reinforcement in the midsection and a softer feel for the head, shoulders, and legs. A support core of pocketed coils completes the hybrid design. The cover is made from a blend of recycled polyester from plastic bottles, cotton, and rayon

How It Performed

The AirScape layer is perforated with small holes, allowing air to circulate near the surface and offset some of the foam’s heat-trapping tendencies. A breathable cover and a pocketed coil system that promotes consistent airflow also add to the Original Hybrid’s temperature-neutral feel. Both foam layers absorb movement and significantly reduce motion transfer, so the mattress should also be suitable for couples. The mid-range firmness and sturdy hybrid design is a good fit for side and back sleepers, especially those who weigh up to 230 pounds.

The Original Hybrid has a price-point that’s on par with other hybrid models and shipping is free for all customers in the contiguous U.S. and provincial Canada. Your order includes a 100-night sleep trial for testing out the mattress and deciding whether it’s right for you, as well as a 10-year manufacturer’s warranty should you keep it after the trial period ends.

Lab Notes – What Our Testers Thought

“The Original Hybrid’s mixed-foam design and mid-level firmness are great for people who enjoy the stability of a coil mattress but also need a sleep surface that contours closely. Most of our side sleepers appreciated the softer feel compared to other hybrids.”

GhostBed Luxe

SleepFoundation.org readers get 30% off mattresses & 2 free luxury pillows ($190 Value) or 40% off the adjustable bundle. No code necessary.

The GhostBed Luxe stands out thanks to a plush medium (5) feel and an above-average profile. The plush foam design makes the bed a solid choice for couples looking for a mattress with strong motion isolation.

What It’s Made of

The mattress is constructed with a thick memory foam comfort layer that contours quite closely. Transitional and base layers of denser polyfoam offer support to keep you on an even plane, while a cover of proprietary GhostIce fabric helps the surface stay cool despite the foam’s heat-absorbing properties. Excessive sagging and bothersome heat retention are two common complaints about memory foam mattresses, so these components give the Luxe a leg up on competitors.

How It Performed

The close contouring makes the GhostBed Luxe most comfortable for people who weigh less than 130 pounds – though side sleepers who weigh more will also enjoy the deep body-cradling sensation. Couples will likely love this mattress because motion transfer is virtually non-existent thanks to the all-foam design. You and your partner won’t feel any ripple effects when the other person changes positions or gets up during the night, ensuring fewer sleep disruptions. The GhostBed Luxe is also completely silent when bearing weight.

Although the Luxe’s sticker price is a bit high compared to the average memory foam mattress, you’ll receive a warranty that covers structural defects for up to 25 years. Ground delivery is also free for anyone in the contiguous U.S., and each order comes with a 101-night sleep trial that includes free shipping on all returns.

Lab Notes – What Our Testers Thought
““I lied on the bed next to another tester and felt virtually no movement when the other tester rolled around. We highly recommend this bed for people with restless sleep partners.”

The Nolah Evolution 15 is a hybrid mattress that alleviates pressure and provides sturdy support, making it particularly well-suited to side sleepers who wake up feeling sore or stiff. Multiple firmness options also make the mattress accessible to a wide range of body types. Though it carries a luxury price-point, this Nolah mattress has high-quality materials and features that may be a worthwhile investment for those who prefer or sometimes use the side position.

What It’s Made of

The Evolution’s 8-inch pocketed coil support core sits atop a 1-inch polyfoam base. The pocketed coils have a zoned support system, so you’ll feel more reinforcement in pressure-prone areas like your hips.

The comfort system is made from three, 2-inch polyfoam layers that each have a different purpose. The bottommost layer is resilient and provides a comfortable transition between the core and other comfort layers. The next layer, a proprietary foam called AirFoamICE, is infused with graphite and idesigned to regulate temperature. Lastly, the quilted polyfoam Euro-top is infused with Nolah’s ArcticTex, a material intended to help you stay cool.

How It Performed

Together, all five layers of the Evolution provide a supportive and cushioning surface that helps alleviate pressure. The mattress is available in three firmness levels: plush (5), luxury firm (6), and firm (8). Side sleepers will likely feel most comfortable on the plush or luxury firm, depending on how much they weigh and the amount of support they need.

The mattress has significant edge support, thanks to its reinforced perimeter. Like other hybrids with cooling comfort layers, the Evolution 15 also offers excellent temperature control.

Nolah ships the Evolution for free to shoppers who live in the contiguous U.S. The mattress is backed with a 120-night sleep trial and lifetime limited warranty.

Lab Notes – What Our Testers Thought

“The Evolution 15’s thick profile will probably appeal to side sleepers who want a softer feel on the surface but also need that next-level support. The mattress has plenty of cushioning but the coils provide extra reinforcement where it’s needed.”

Why You Should Trust Us

We rely on our team of sleep experts to research, evaluate, and rate a wide range of sleep products. To date, we’ve personally tested hundreds of individual mattress models. Our list of the best mattresses for side sleepers is primarily based on feedback from testers who exclusively sleep on their sides, though we also drew from experiences of combination sleepers who alternate between side sleeping and back and/or stomach sleeping. The team consists of people who fall into different weight groups to ensure our findings are inclusive of all body types.

Side sleepers typically need more cushioning to ensure even alignment and minimal pressure along the spine. To test mattresses for side sleeping, we use body-mapping sensors to detect pressure buildup in sensitive areas like the shoulders and hips. We also measure sinkage beneath the tester’s body to determine whether the mattress offers adequate support for people of different weights. The top picks listed above reflect our overall findings.

How Sleeping on Your Side Affects Sleep

Sleeping on your side is highly regarded within the medical community, and its benefits are compelling. Not only does side sleeping open your airways and reduce snoring and symptoms of sleep apnea, but it may also improve brain health and help prevent certain neurological issues. For people with heartburn, and especially for pregnant women, sleeping on your left side has been shown to reduce acid reflux. This sleeping position is also best for keeping your spine aligned, though there are measures you should take to ensure your body and spine get the proper support when sleeping on your side. Putting too much pressure on your neck, shoulders, and back can result in aches and pains.

Spine Alignment

When the spine is aligned, it is in a straight, neutral position. If the spine is misaligned during sleep, this can result in back pain and other issues. Though side sleeping is the least likely position to exacerbate spinal pain and other symptoms, there are still precautions that should be taken to ensure the spine is aligned as you sleep.

A contouring mattress responds proportionately to pressure points, cushioning the hips and shoulders. This helps keep the spine in neutral alignment. Side sleepers who maintain a symmetrical position are less likely to have back pain. This means sleeping on your side with your legs stretched out, and a higher loft pillow underneath your head. To keep your hips square, you may choose to sleep with a thinner pillow between your knees. The neck is part of the spine, so it is also important to keep your neck supported and resist tucking in your chin. These measures will help your spine maintain a neutral position.

Side Sleepers With Shoulder Pain

Since side sleepers put pressure on one shoulder as they sleep, they are more likely to experience pain on the side that they sleep on. The added weight on the shoulder, especially if the mattress does not offer enough cushioning or contouring support, can result in neck and shoulder pain. Those who sleep on their side are also more likely to push one shoulder up towards their neck, which causes the spine to be misaligned.

Purchasing a mattress with the right firmness is an essential step towards reducing shoulder pain for side sleepers. It is also important to keep in mind your weight, as lighter people will not press into the mattress as much, and heavier people will put more pressure on the mattress. The mattress should cushion the shoulder and prevent it from sinking in too deeply, or not enough. The right pillow can also make a difference. The loft of the pillow should be high enough to keep your head and neck in line, and help prevent your shoulder from pushing up towards your neck.

Side Sleepers With Back Problems

For side sleepers with back problems, the right mattress can make all the difference. If a mattress does not contour to the shape of the body and provide ample support, this can cause a misalignment in the joints and the spine. As a result, your muscles can’t relax and have to work overtime to keep everything aligned. A contouring mattress, on the other hand, keeps the spine aligned and relieves joint pain. This keeps the hips and shoulders aligned as well. Some mattresses also have customized support for the lumbar region.

The simplest way to determine if your back pain is caused by your mattress is to pay attention to your back pain throughout the day. If you wake up with back pain that subsides or lessens as the day goes on, your mattress is likely the culprit. The best mattress for side sleepers will provide a flat, even surface without any sagging or indentations. A responsive material, like memory foam, will cushion pressure points and keep the spine aligned. The mattress should provide full-body support to prevent back pain.

Which Mattress Firmness is Best for Side Sleepers?

Mattress firmness is a subjective measure of comfort, so whether you choose a soft or firm mattress for sleeping on your side will depend on several factors. Mattresses are usually rated on a firmness scale of 1 to 10, or extremely soft to extremely firm. Medium soft to medium firm mattresses are most common.

For side sleepers, mattress firmness determines how cushioned the pressure points are. It affects how much the shoulders and hips sink into the mattress, which helps keep the spine aligned. A comfortable mattress will alleviate aches and pains.

There are a few factors to consider when deciding on mattress firmness, including personal preferences, body weight, and mattress type. Heavier people press deeper into the mattress, so the same mattress may feel different to people depending on their weight and body type. The comfort layers affect the firmness and feel of the mattress. Memory foam conforms closely to the shape of the body, while latex offers gentle contouring with more bounce. Innerspring coils can add firmness to a mattress. Of the several types of mattresses available, each has benefits and drawbacks for side sleepers.

Which Type of Mattress is Best for Side Sleepers?

The best mattress for side sleepers will offer consistent support and contouring comfort. Most mattresses fall into one of the following categories. These are the most common mattress types on the market today, and understanding the difference between each type is key to determining which mattress is right for you. Though specific mattress models will vary in materials, construction, and unique features, there are commonalities within each category that will help you decide what type of mattress best suits your needs.

Hybrid

Definition: A hybrid mattress has an innerspring support system with thick comfort layers of memory foam or latex. Combining elements of these different types of mattresses into a hybrid design maximizes the benefits of each, with fewer drawbacks. A hybrid mattress may include a transition layer of polyfoam or micro coils beneath the foam comfort layers. The base of innerspring coils adds airflow and support to the mattress.

Highlight: Contouring support with temperature regulation.

Since a hybrid mattress has substantial comfort layers, it tends to provide contouring support that relieves pressure points and keeps the spine aligned. While an all-foam mattress can restrict airflow and retain heat, a hybrid mattress typically has better temperature regulation due to the innerspring coils. For side sleepers, this means conforming comfort without overheating

Innerspring

Definition: An innerspring mattress has a support base of steel coils, with thin comfort layers of fiber or foam. This traditional mattress style is minimalistic and offers less contouring than a hybrid or foam mattress. Widely available and easily recognizable, innerspring mattresses also tend to be affordable.

Highlight: Enhanced edge support.

The steel coil support base of an innerspring mattress can be reinforced for better edge support. This increases the supportive surface area of the bed, ensuring side sleepers who sleep near the edge of the bed experience consistent support. It also prevents sagging along the edges over time.

Latex

Definition: A latex mattress is constructed with latex comfort layers and a latex support base. This type of mattress is most often made with natural latex, which is manufactured with sap harvested from rubber trees. The sap is then processed with the Dunlop or Talalay method. Dunlop latex is dense and durable, while Talalay latex is lighter and softer. Synthetic latex can also be used; this type of latex is made with petrochemicals.

Highlight: Responsive.

Latex gently contours to the shape of your body, alleviating pressure points while preventing the feeling of sinking in too deeply. For side sleepers, this reduces shoulder and back pain. There is also more airflow around the body and better temperature regulation.

Airbed

Definition: In an airbed mattress, the support comes from internal rubber chambers that are inflatable. The firmness is adjustable by filling the chambers with air, or removing air as needed. Airbed mattresses are often remote-controlled or can be paired with a smartphone app. The built-in pump adjusts the chambers to your preference. This type of mattress usually has comfort layers of foam, latex, wool or other fibers.

Highlight: Customizable Firmness

For side sleepers who are unsure of what their preferred firmness level is, or for those who find their needs change, an airbed mattress offers customizable firmness. Some airbed mattresses include two air chambers, so people who share the bed and have different preferences can adjust their sides individually. Certain models even include adjustability for different parts of the body. For side sleepers, this can mean adjusting the firmness under the shoulders and hips to keep the spine aligned.

Foam

Definition: A foam mattress has comfort layers and a support base of foam. The comfort system is often made with memory foam layers, and can include traditional viscoelastic memory foam, open-cell foam, or gel-infused foam. The support base is usually constructed with high-density polyfoam for added support and durability.

Highlight: Cushions pressure points.

Memory foam contours closely to the body, responding to pressure and cushioning areas like the hips and shoulders. For side sleepers, this promotes proper spinal alignment and reduces aches and pains.

Accessories Important For Sleeping on Your Side

A mattress that offers full-body support and contouring is the most important purchase for side sleepers. Further customizing the mattress with sleep accessories, including pillows and mattress toppers, can make side sleeping more comfortable. Pillows ensure the head and neck are aligned, while mattress toppers can change the comfort system of the bed. Understanding what to look for in these sleep accessories is important for both comfort and support.

Pillows

When sleeping on your side, a pillow for your head is necessary for spinal alignment. A medium or high loft pillow should lift your head enough to keep both your head and neck aligned with your spine. This relieves pressure on the neck and shoulders. The following table outlines the ideal pillow loft based on sleeping position.

Sleeping Position Pillow Loft Recommended
Back Medium
Side Medium or High
Stomach Low

In addition to having a comfortable pillow under your head, knee pillows (or regular pillows) can be used to further customize your sleeping position and alleviate aches and pains. Side sleepers will benefit from drawing their legs up slightly toward their chest, and placing a pillow between their knees. This helps keep the hips square and spine aligned.

Mattress Toppers

A mattress topper is a comfort layer that sits on top of your existing mattress. Toppers are usually made with memory foam, latex, or other common comfort layer materials. Adding a thicker comfort layer to your current mattress can increase the level of contouring and pressure point relief your mattress provides. This helps to alleviate back and joint pain.

Selecting a memory foam mattress topper gives you the chance to try out this material without committing to a new memory foam mattress. While you will not experience the full advantages of a memory foam mattress from just a topper, it is less expensive than purchasing an all-new mattress. It can also be a stepping stone to buying a new mattress if you decide you like the material.

Before purchasing a mattress topper, be sure to evaluate the current condition of your mattress. A mattress topper will enhance the comfort of a mattress, but it will not offer support or fix a broken mattress. If your mattress is sagging or unsupportive, it is time for an all-new mattress.

What Mattress Features Are Important For Side Sleepers?

Due to added pressure put on the shoulders and hips, there are special considerations that side sleepers should keep in mind when shopping for a mattress. Mattress companies can often use misleading terminology, or exaggerate some of the benefits of unique features. The following factors are the most important to consider when shopping for a new mattress.

  • Mattress Type: Each mattress type has pros and cons, but for side sleepers, it is important that the mattress offers contouring and full-body support. The type of mattress you purchase determines other key components, including temperature regulation, motion isolation, and pressure point relief. Understanding your priorities and preferences will help you select the right mattress type.
  • Contouring: How a mattress responds to pressure and conforms to the shape of your body determines how well it contours. A contouring mattress keeps the spine aligned and cushions pressure points, which are essential factors for side sleepers.
  • Quality Materials: The quality of materials used directly affects the durability of a mattress. While high-quality materials can be more expensive, they often increase the lifespan of a mattress and make it a more valuable investment. Cheaper materials can break down more quickly and offer less support over time.
  • Firmness Level: While this is a subjective measure of comfort, side sleepers need a balance of soft cushioning for the shoulders and hips and support to keep the spine aligned. Consider your personal preferences and weight as well, as these can affect which firmness level will provide the most comfort and support.
  • Pressure Relief: Side sleeping puts pressure on the shoulders and hips. Contouring materials like memory foam and latex relieve pressure points and prevent shoulder and back pain for side sleepers.

Tips for Sleeping on Your Side Comfortably

Although side sleeping can interfere with spinal alignment and create pressure buildup, there are measures you can take to comfortably use this position.

  • Hug a second pillow while you sleep. This provides additional upper body support.
  • Tuck a pillow between your knees to reduce pressure in the lower back and hips. If you use a longer body pillow, you may be able to hug the pillow and place it between your knees.
  • Make sure your pillow has enough loft to maintain even alignment. Most side sleepers prefer pillows with medium to high loft because they provide the most head and neck support.
  • Invest in a softer topper if your mattress feels too firm. Side sleepers can benefit from extra cushioning around the shoulders and hips if their mattress surface is too stiff or rigid.
  • Sleep close to the center of your mattress if the edges aren’t reinforced. Some mattresses – all-foam and all-latex models in particular – tend to sink along the perimeter due to weak or inadequate edge support, and lying on an uneven surface can cause aches and pains to occur.

Frequently Asked Questions

  • What mattress types are best for side sleepers?

    Since side sleepers require significant pressure relief, people who prefer this position should consider a hybrid or all-foam mattress. While some innerspring models do contour enough for side sleepers, almost every high-performing hybrid or foam mattress offers enough pressure relief to prevent pressure sores, aches, and pains.

    Memory foam comfort layers perform best, but some people dislike its characteristic “cradling” sensation. For people who prefer to feel as though they are sleeping “on” their bed, rather than “in” it, natural latex foam can be a pressure-relieving alternative. Latex mattresses can be purchased with a latex, polyfoam, or pocketed coil support core, depending on your budget and support preferences.

  • How firm should a mattress be for a side sleeper?

    Side sleepers usually prefer mattresses that are between medium-soft and medium-firm, but choosing a specific firmness should always be made with your weight in mind. People who weigh below 130 pounds usually need a softer mattress, while people above 230 pounds require firmer support.

    Your subjective experience will depend on how much the mattress compresses beneath you, so the right firmness will always feel balanced and comfortable. However, side sleepers can sometimes feel that the correct firmness level causes pressure points or pain at their shoulder or hip. Purchasing a bed with better pressure relief is the best answer since it will prevent pressure points without compromising support as a softer mattress would.

  • What mattress is best for side sleepers with back pain?

    Spinal alignment is particularly important for side sleepers with back pain, making features like ergonomic zoning more critical than they might be for other people. This is most common in hybrid mattresses since pocketed coils can be individually tuned to provide zoned support that targets areas like the pelvis and shoulders. Pocketed coils also compress individually, allowing for better alignment than innerspring mattresses and more structured support than mattresses with a polyfoam core.

  • What mattress is best for side sleepers with shoulder pain?

    Side sleepers usually experience shoulder pain when their mattress does not offer enough pressure relief. The ideal mattress for a side sleeper contours gently around the point where their shoulder presses into the mattress, allowing for correct alignment through the upper back and preventing their weight from resting directly on the point of their shoulder.

    Some people mistake a lack of pressure relief for their mattress being too firm, but buying a softer mattress is more likely to increase shoulder pain than relieve it. Instead, look for a hybrid or all-foam mattress with a memory foam or pressure-relieving polyfoam comfort system.

  • What mattress is best for side sleepers with hip pain?

    Hybrid mattresses are an excellent choice for side sleepers who experience hip pain. Pocketed coils provide support and encourage proper spinal alignment, while a pressure-relieving comfort layer helps prevent pressure points and lumbar tension. A sufficiently firm all-foam mattress can also help relieve hip pain. Some side sleepers may also find that placing a pillow between their knees reduces their hip pain, regardless of their mattress.

  • Is a softer mattress better for side sleepers?

    Side sleepers exert a lot of pressure on their hips and shoulders during sleep. As a result, pressure may build up overnight and lead to discomfort or pain. Soft mattresses can help side sleepers by cradling the shoulders and hips, in effect preventing pressure from building up too much. However, keep in mind that side sleepers also need support from their mattress to prevent the midsection from sinking in and misaligning the spine. So while soft mattresses can help promote good sleep posture in side sleepers, the mattress should also provide adequate support.

    Sleepers in lighter weight categories are most likely to benefit from a soft mattress. Since their bodies don’t sink as deep into the mattress as heavier sleepers, they will receive sufficient support while still benefiting from the bed’s contouring.
