Soft mattresses are great for sleepers who weigh under 230 pounds and prefer a plusher surface. The soft feel allows sleepers to sink in more, providing extra conforming that can help relieve pressure points.
While soft mattresses can offer a comfortable night’s sleep, a mattress can also be too soft. A mattress that is too soft may allow a sleeper’s hips and shoulders to sink in too deeply. This can overcompress the foam, creating more pressure points around the hips and shoulders. It can also lead to improper spinal alignment, which may place strain on the spine.
When buying a mattress online, customers don’t have the benefit of being able to lie on a mattress while they’re shopping. Relying on the 10-point firmness scale is the easiest way to judge whether a mattress matches your firmness preference.
In this guide, we’ll share our picks for the best soft mattresses, explain what you may need to consider as you shop, and discuss the different types of soft mattresses.
The Amerisleep AS5 memory foam mattress offers a comfortable balance of cushioning and zoned support, as well as a celliant cover engineered to promote physical recovery.
The AS5 is Amerisleep’s softest model. This all-foam mattress is crafted to gently cradle the sleeper but regain its shape quickly when you change position.
The plant-based foam comfort layer has an open-cell structure, allowing airflow to pull heat away from the sleep surface. Like most foam mattresses, the AS5’s comfort layer contours to each sleeper’s body to relieve pressure. However, it is also engineered to be more responsive than some foams.
Underneath the comfort layer, a five-zone transition layer gives targeted support to better align the spine. There is extra support for the sleeper’s head, back, and legs, and extra cushion for their hips and shoulders. An additional transition layer is designed to balance cradling and responsiveness, relieving pressure without the “trapped in the bed” feeling of some all-foam models. A foam base layer is engineered to provide lasting support for the rest of the mattress.
The AS5’s mattress cover is constructed of Celliant fabric, which is a responsive fabric crafted to reflect the body’s energy back towards it. This is thought to promote cell recovery, aid restful sleep, improve blood flow, and more.
Amerisleep offers a 100-night sleep trial and a 20-year warranty for the AS5 Mattress.
The flippable Nolah Signature caters to a wide range of sleep positions and body types thanks to a sleep surface with a different firmness level on each side.
The Nolah Signature is an all-foam mattress constructed of four layers of foam. This all-foam construction provides exceptional motion isolation and pressure relief while being whisper-quiet.
The Nolah Signature Mattress is flippable, allowing sleepers to select between a medium-soft side, rating around 4 on the firmness scale, and a firm side, which rates around 7 or 8.
Because the mattress is flippable, each side of the mattress has a separate comfort layer. Both of these comfort layers uses proprietary polyfoam engineered to respond quickly to changes in pressure, relieve pressure points, and dissipate heat.
Underneath the top layer of the soft side of the mattress, there is a second layer of polyfoam crafted for resilience, bounce, and durability.
The Nolah Signature’s support core uses high-density polyfoam to provide a sturdy base for the comfort layers.
The Nolah Signature Mattress comes with a lifetime warranty and 120-night sleep trial.
The Leesa Original is an affordable memory foam mattress that contours to the body for targeted pressure relief and weight distribution.
The Leesa Original is an all-foam bed that has become a staple of the online mattress industry. Simple and affordable, the Leesa provides that quintessential memory foam feel, and is softer than the average all-foam bed.
The comfort layers of the Leesa consists of two different foam layers. The first is polyfoam, and the second is memory foam. These two foams conform closely to the sleeper’s body, which eases pressure on the back and shoulders while providing a sensation of being hugged by the mattress. The support core is made of high density polyfoam, and serves as a base that prevents sleepers from sinking too deep into the mattress.
Like most memory foam beds, the Leesa provides great pressure relief and prevents motion from transferring across the surface, making it a good option for both people with pain-related issues and couples. The Leesa Original has a medium (5 out of 10) firmness, making it most ideal for side and back sleepers under 230 pounds.
One of the biggest selling points of the Leesa is its price point, which is below average for a memory foam mattress — especially one of this quality. Additionally, Leesa offers a 100-night sleep trial and 10 year warranty. They ship for free to all 50 US states, and offer White Glove Delivery for an additional fee.
Tuft & Needle’s Mint Mattress offers moderate yet even contouring and excellent pressure relief for side and back sleepers.
Due to its medium firm (6) feel, the Mint Mattress from Tuft & Needle is a bit firmer than our other top picks and may not conform as closely. However, the mattress is constructed with a 3-inch comfort layer of adaptive open-cell polyfoam that offers ample cushioning for side and back sleepers who weigh up to 230 pounds. Transitional and support layers of denser polyfoam reinforce your body to prevent you from sinking too much – a common complaint regarding softer mattresses.
The top two layers are infused with graphite and gel, both of which have cooling properties to help draw heat away from your body. Open-cell polyfoam is also fairly breathable on its own, so overall the mattress should sleep noticeably cooler than many competing all-foam models. Additionally, the cover is embedded with antimicrobial protectant to stave off bacteria and other harmful contaminants that can decrease the quality of your mattress and shorten its lifespan. Couples should experience fewer sleep disturbances on the Mint Mattress too. The foams absorb movement and reduce transfer quite well, and the bed does not make any noise.
The Mint Mattress has a sticker price that is on par with the average all-polyfoam model. Tuft & Needle offers free ground shipping anywhere in the contiguous U.S., and backs the mattress with a 100-night sleep trial and a 10-year warranty.
The Idle Gel Plush conforms closely thanks to thick foam layers that also retain minimal body heat and sleep fairly cool.
Measuring 14 inches thick, the Idle Gel Plush is constructed with a thick comfort system and designed for a medium (5) feel. Two comfort layers of adaptive polyfoam and a memory foam transitional layer deliver close contouring. Side sleepers receive ample cushioning for the shoulders and hips, which promotes even spinal alignment and alleviates pressure points throughout the body. Back sleepers who weigh less than 130 pounds should also be able to rest comfortably without sinking too much.
Temperature neutrality is a major strength of the Idle Gel Plush. While many all-foam beds retain body heat to a bothersome degree, this mattress is constructed from breathable foams and also features a cover made from IceCool fabric. These features allow the Idle Gel Plush to sleep very cool compared to its competitors. Couples should also experience fewer sleep disturbances because the mattress nearly eliminates motion transfer and does not produce any noise.
Idle Sleep provides an 18-month sleep trial for the mattress. This is quite long compared to the standard trial period, which typically runs 90-100 nights. The Idle Gel Plush is also backed by a lifetime warranty and all customers in the contiguous U.S. receive free ground shipping.
The coil-on-coil WinkBed mattress delivers a responsive yet conforming feel and excellent edge support thanks to its zoned support core.
The WinkBed Mattress comes in four firmness options: soft (4), medium (6), firm (7-8), and Plus (7-8). While all four of these options use a hybrid design, the exact construction varies slightly between models.
The soft, medium, and firm mattresses have a Euro-pillow top, which is quilted with gel-infused foam engineered to pull heat away from the body. Underneath the Euro-pillow top, the WinkBed’s comfort system also includes a layer of pocketed microcoils. The microcoils allow for extra cooling airflow. The Plus version of the mattress uses polyfoam and zoned latex in its comfort system.
Each firmness option uses a zoned coil support layer. The coils are pocketed to allow them to move independently of each other, while the zoning provides targeted support and softness to help align the spine. The soft version of the mattress uses a 5-zone coil system. The medium and firm models use a 7-zone system. The Plus uses a 3-zone system. The WinkBed’s support layer also includes a sturdy, reinforced edge to increase the usable surface area of the mattress.
The WinkBed Mattress comes with a lifetime warranty and a 120-night sleep trial.
The Bear Pro is designed with layers of copper-infused and gel-infused foam to regulate body temperature, along with sturdy support layers that stabilize the mattress well.
The Bear Pro Mattress uses four layers of foam to contour to the sleeper’s body while supporting spinal alignment.
Consisting of two layers, the Bear Pro’s comfort system cradles the sleeper to provide pressure relief. Foam comfort layers often trap heat, but the Bear Pro uses special foams to reduce heat retention. The top layer is infused with copper, which pulls away excessive heat. The second layer uses gel memory foam for additional heat dispersal and contouring.
A layer of transition foam acts as a barrier to prevent sleepers from sinking in against the firm support core. The high-density polyfoam support core gives the Bear Pro Mattress structural integrity.
Sleepers looking for additional relief may appreciate the Bear Pro’s Celliant cover. Celliant is a responsive fabric engineered to aid recovery, regulate temperature, and promote a restful night’s sleep.
The Bear Pro has a medium-firm feel, rating around 6 on the firmness scale.
The Bear Pro Mattress has a 10-year limited warranty and a 100-night sleep trial.
The luxurious Brooklyn Bedding Aurora features a phase-change cover for above-average temperature control, thick foam comfort layers, and a responsive coil support core.
The Brooklyn Bedding Aurora is a hybrid model that pairs multiple layers of foam with a coil support core. This construction combines the benefits of both foam and innerspring mattresses.
The Aurora’s two comfort layers cradle to the sleeper’s body, relieving pressure. The foam also isolates motion to a significant extent, so sleepers might notice when their partners change position during the night.
Because the Aurora uses pocketed coils in its support core, the coils can move independently of each other, further reducing the spread of motion across the surface of the mattress. The coil layer also gives the mattress bounce and edge support.
While foam comfort layers have a reputation for trapping heat, the Aurora fights that trend with phase change materials that make the mattress cool to the touch. The innerspring layer is breathable, allowing more airflow to further dissipate heat.
The Brooklyn Bedding Aurora is one of our picks for the best soft mattresses, but it comes in three firmness options to accommodate more needs and preferences. It is available in medium-soft (4), medium-firm (6), and firm (7-8).
Not only does the Puffy Lux provide precise body-contouring and pressure relief, but it also absorbs motion to eliminate transfer and reduce nighttime disturbances for couples.
The Puffy Lux is an all-foam model that has the close conforming that many sleepers look for in a soft mattress without skimping on the support needed to promote proper spinal alignment.
The Puffy Lux has two layers in its comfort system. The top layer is constructed of Cooling Cloud Foam, a visco polyurethane foam. This layer has a gel-infusion to help wick away heat and promote a cooler night’s sleep. The second layer uses Dual Cloud Foam, which is engineered to soften under a sleeper’s pressure points while supporting the body.
The Puffy Lux’s transition layer uses Climate Comfort foam, which is crafted to resist shrinking or expanding when the room temperature fluctuates while preventing sleepers from sinking in against the support core. The support core uses firm polyfoam to stabilize the sleep surface.
The mattress cover is stain-resistant and washable for easy cleaning.
The Puffy Lux has a medium feel, rating around 5 on the 10-point firmness scale. While it is designed to adapt to all sleep positions, the Puffy Lux’s exceptional contouring may make it particularly appealing to side sleepers looking for pressure point relief.
Puffy provides a 101-night sleep trial and a lifetime warranty for the Puffy Lux mattress.
The Zotto Mattress is built with dense support layers to reduce sinkage and maintain support better than many of its all-foam competitors.
The Zotto Mattress is a memory foam bed that uses multiple layers of foam to provide a strong blend of pressure-relieving comfort and full-body support. The bed has a medium firm (6) feel that is well-suited to a wide variety of different kinds of sleepers. Each foam is specialized to add a unique benefit to the bed. Zotto’s foams are all CertiPUR-US certified to be made without a number of harmful chemicals, as well as ozone depleters.
The Zotto Mattress starts with a top layer of responsive, yet cushioning proprietary polyfoam. This polyfoam is then bolstered by a layer of memory foam, which redistributes a sleeper’s weight around their pressure points for thorough comfort. Although memory foam has a reputation for trapping heat, the Zotto uses cooling, gel-infused foam technology and a breathable design to draw excess heat away from sleepers and allow it to dissipate before it builds up.
A transitional polyfoam layer is built to lend the bed additional bounce and pressure relief, while acting as a buffer to keep sleepers from sinking into the support core. The bed’s core is constructed from durable, high-density polyfoam, adding sturdy pushback to keep most sleepers comfortable and supported throughout the night. The entire mattress is wrapped in a smooth polyester cover.
The Zotto Mattress ships for free to the contiguous United States. The bed is backed by a 100-night sleep trial as well as a 10-year limited warranty.
Soft mattresses usually appeal most to side sleepers and those who weigh under 130 pounds. Lightweight sleepers exert less force on a mattress than heavier sleepers, which means firmer mattresses often don’t compress enough to provide lightweight sleepers with cradling and pressure relief. When a mattress is too firm, side sleepers are particularly prone to pressure buildup in their hips and shoulders. A soft mattress will allow a side sleeper’s hips and shoulders to sink in more, promoting better spinal alignment.
Back and stomach sleepers below 130 pounds who like a plusher surface may also enjoy a softer mattress. However, since back and stomach sleepers often prefer a slightly firmer feel, a soft mattress may not be as important for back and stomach sleeper. Back and stomach sleepers frequently need extra support to prevent their midsections from sinking in too deeply. The right soft mattress should be able to support the sleeper and add plushness.
Sleepers who weight between 130 and 230 pounds who prefer a plush feel may also enjoy soft mattresses. This is especially true of side sleepers, who may suffer from sharp pressure points on an overly firm mattress. Some side sleepers weighing more than 230 pounds may also appreciate the hug of a soft mattress, though sleepers in higher weight groups may experience excessive sinking in the hips and shoulders, which could place a strain on the spine.

Sleep position is one of the key factors that affects how an individual interacts with a mattress. The position a person sleeps in influences which parts of the body press against the mattress. It can also impact the amount of pressure placed on the spine.
Soft mattresses are usually most compatible with side sleeping. When an individual sleeps on their side, the widest parts of their body (their hips and shoulders) put the most pressure on the mattress. For pressure point relief, a mattress must have sufficient cushioning in these regions. To promote proper spinal alignment, the mattress must also have enough support to prevent the hips and shoulders from sinking in too deeply.
Soft mattresses are not usually as conducive to back and stomach sleeping. Back and stomach sleepers often require more support to prevent their midsections from sinking too far into the mattress. Some soft mattresses may give sufficient support for these sleep positions, especially if they contain zoned layers. Many back and stomach sleepers favor a slightly firmer feel.
While individuals from any weight group may enjoy a soft mattress, sleepers who weigh under 130 pounds usually gravitate to this feel more than other weight groups.
Sleepers who weigh less put less pressure on the surface of a mattress. Firmer mattresses may not have enough give to allow lightweight sleepers to sink in, which may put the spine out of alignment and cause the sleeper to suffer from more severe pressure points. Softer mattresses generally provide more conforming for lightweight sleepers, relieving pressure points and encouraging better spinal alignment across all sleep positions.
Shopping for a mattress online can be incredibly convenient and allow you to compare multiple models quickly and easily. However, without trying the mattress in person, customers don’t always know how to anticipate what the mattress will feel like. Paying attention to the firmness rating can give shoppers a clearer idea of how a mattress might feel. Reading customer reviews will also give extra insight.
Many direct-to-consumer mattress companies offer sleep trials during which customers can return their mattress for a refund of the purchase price. Before purchasing a mattress online, we encourage customers to take a company’s trial period and return policies into account.
With so many mattresses available online, deciding where to shop may be the first big obstacle in the mattress-buying process. Some shoppers like to start by looking at well-known brands like Casper, Leesa, Nectar, Purple, Saatva, and Tuft & Needle. Deciding what mattress features you prioritize can help narrow your options. From there, reading mattress reviews can further refine your search.
Some mattresses will offer additional options like different heights, different firmnesses, White Glove delivery, or optional add-ons. After you add your selection to your cart and proceed to checkout, you will generally be asked to input your contact and shipping information and pay via credit card.
Many mattresses run limited time promotions throughout the year, so you might find discounts or offers for a free item with your mattress purchase at any time. However, some of the best deals usually fall on holiday weekends around Martin Luther King Jr. Day, President’s Day, Memorial Day, Fourth of July, Labor Day, and Black Friday.
To save additional money shopping for a mattress online, you might check for special offers through your credit card or a cash back program like Rakuten.
Some companies may use confusing words that distract customers from more important considerations. For instance, some companies may describe a mattress as “more comfortable” or “the most comfortable.” However, since comfort is subjective, this may not be true for everyone. Similarly, shoppers may be drawn to proprietary materials with appealing names. Some of these materials are unique, but their presence doesn’t mean one mattress is inherently superior to another.
Focusing on the following considerations can give shoppers a clearer idea of how a mattress may affect their sleep experience.
Below, we’ll detail the most common mattress types. All mattress types offer a soft option, but the materials and build can affect the overall sleep experience. While some features and characteristics tend to be consistent between different models within one type category, individual models vary quite a bit due to design, materials, and build.
Definition: Hybrid mattresses combine a significant comfort system with a coil support core. The composition of the comfort system varies between models, but many contain layers of cotton, wool, polyfoam, memory foam, latex, microcoils, and/or a combination of several different materials.
Highlight: Balanced Benefits. Hybrid models often combine the best traits of innerspring mattresses and latex or foam mattresses. The coil layer usually gives hybrids more bounce, breathability, and edge support than most all-foam or all-latex models, while the substantial comfort layers provide more contouring, motion isolation, and pressure relief than most innerspring models.
Definition: Innerspring mattresses are generally considered more traditional than foam, latex, or hybrid models. An innerspring mattress’s most notable component is its metal coils. Some innerspring mattresses may also have a thin layer of cotton or foam for extra softness, but the coil layer is the most significant factor impacting the sleep experience.
Highlight: Affordable. Innerspring mattresses are often lower-priced than other mattress types, so they may appeal to shoppers on a budget.
Definition: All-latex mattresses can be constructed of synthetic latex, natural latex, or a blend of the two. There are two main types of natural latex: Dunlop latex and Talalay latex. The different processes used to craft these types of latex lead to differences in their feel and performance. Dunlop is usually denser and more durable, while Talalay is usually bouncier and more breathable.
Highlight: Contouring Without Sinkage. Latex traditionally contours enough to relieve pressure points. However, rather than compressing exclusively under the weight of the sleeper, the compression is spread out over a wider surface area, which may make the sleeper feel like they are floating on top of the mattress rather than sinking into the mattress.
Definition: Airbeds contain air chambers that can be filled or emptied to adjust the firmness of the bed. Modern airbeds often include remotes or apps to adjust the bed easily, while others may use a hand crank. Materials vary between models, but they may include thin comfort layers of memory foam, polyfoam, latex, cotton, and/or polyester. The support cores frequently use PVC, rubber, and/or polyurethane.
Highlight: Customizable Firmness. Airbeds are easy to adjust, allowing sleepers to change the feel based on their preference, even if that varies between nights. However, since most airbeds have a thin comfort layer, it might not be possible to achieve the plush feel some sleepers look for from a soft mattress.
Definition: All-foam mattresses are generally crafted of multiple layers of foam, which may include memory foam, polyfoam, or a combination of the two. Latex may also be included in some all-foam models.
Highlight: Close Conforming. Memory foam and polyfoam generally compress directly under a sleeper’s weight rather than spreading the compression across a wider area. Because of this, most soft all-foam models conform closely to the sleeper’s body, creating a hugging sensation. This can help relieve pressure points.
The right sleep accessories can complement your soft mattress to create a plush and appealing sleep surface. You can use these accessories to adjust the feel of your existing mattress or fine-tune the feel of a new mattress.
Since soft mattresses tend to allow sleepers to sink in more deeply than they would on a firmer mattress, sleepers may require a softer, lower-loft pillow. A pillow that is too firm or too lofty may lift the head up beyond the point of proper alignment and put more pressure on the neck.
Side sleepers may benefit from a medium-loft pillow. Due to shoulder width, a side sleeper’s head usually needs more support to keep the spine properly aligned. Ideally, side sleepers should aim to find a pillow that fills the gap between their neck and the mattress without lifting the head or neck up beyond the point at which the spine is straight.
Back sleepers may prefer a pillow on the lower end of the medium range. The goal is still to fill the gap between the neck and mattress, but this gap is not as large with back sleepers, so they usually do not need as lofty of a pillow as side sleepers.
Stomach sleepers usually prefer the thinnest pillows or no pillow at all to avoid placing added pressure on the neck.
Explain how a mattress topper can help those looking for a different feel on a mattress they already own. Be sure to explain that this is not a long term solution and won’t give all the benefits of purchasing a new mattress, but may help with minor adjustments.
A mattress topper can be an affordable way to adjust the feel of your current mattress. Mattress toppers generally aren’t a long-term solution to an uncomfortable mattress, and they do not provide the same benefits as a new mattress. However, toppers can tweak the feel of the mattress and provide some extra plushness.
If your existing mattress is too firm, a thicker topper will likely provide a more noticeable change than a thinner topper. However, sleepers looking for a subtler variation may prefer a thinner topper.
Mattresses often soften naturally as they age, so the feel may change on its own over time.
Adjusting your mattress foundation may also contribute to the feel. Using a box spring may make a memory foam mattress feel firmer, so removing the box spring may soften the feel. If you have a hybrid or innerspring model, using a box spring may make it feel softer. Before adjusting your foundation, review the information from the manufacturer so that you don’t risk voiding the warranty.
If you sleep on a memory foam model, increasing the temperature in your bedroom may soften the mattress slightly.
Using a mattress topper, especially a thicker topper, can soften the sleep surface.
An excessively soft mattress can lead to back pain. If a mattress is too soft to support your hips and shoulders properly, they may sink in too deeply. This can place additional pressure on your spine.
A mattress that is too soft can cause hip pain. Soft mattresses compress under the hips to conform to the sleeper’s body. If the mattress is too soft, it could overcompress, and create pressure points.
Whether or not a soft mattress is good for your back will depend largely on your weight and sleep position. Soft mattresses can support proper spinal alignment for most sleepers who weigh under 130 pounds and some side sleepers who weigh over 130 pounds. However, they might not provide enough support for sleepers over 230 pounds, which could lead to back strain.
Babies should not sleep on soft mattresses due to rebreathing and suffocation risks. The American Academy of Pediatrics recommends that infants sleep on a firm sleep surface that complies with their safe sleeping guidelines.
Depending on your weight and sleep position, either a soft or firm mattress may be better for back pain. Soft mattresses provide more conforming, which may promote better spinal alignment for sleepers who weigh under 130 pounds, especially those who sleep on their sides. However, individuals who weigh over 230 pounds, particularly those who sleep on their stomachs or backs, may benefit from a firmer mattress that supports their midsections and prevents them from sinking in too deeply.
Memory foam mattresses may be either firm or soft depending on their construction. Foams can be produced in a wide range of firmness levels, and materials can be layered to create a firm or soft surface.
