In-Depth Reviews
“The Helix Midnight achieves a true medium firm feel, which comes from gently contouring foam layers and a sturdy — but not overly stiff — coil system.

Product Details
Helix’s mattress line includes nearly two dozen hybrids, all of which are designed for specific types of sleepers. The Helix Midnight is one of the brand’s best-selling models, which isn’t surprising — the gently adaptive memory foam and sturdy pocketed coils create an exceptionally balanced medium firm (6) feel. While the Midnight is geared toward side sleepers between 130 and 230 pounds, our tests show this mattress holds a lot of appeal for those with different body types and sleep positions.
What It’s Made of
The Midnight begins with a memory foam comfort layer, followed by a polyfoam transitional layer. These materials gently cushion the body to distribute your weight, promote even alignment, and minimize pressure along the spine. Pocketed coils and dense base foam make up the support core. The perimeter coils are thicker to reinforce the edges and prevent you from sinking too deeply when getting in and out of bed. A knit polyester cover encases the mattress.
This is the standard Helix Midnight model. You can pay more and upgrade to the Midnight Luxe or Midnight Elite, which include extra features such as additional foam layers, zoned coils, and phase change covers. These models are also covered under longer warranties.
How It Performed
During our hands-on tests, the Midnight earned its most favorable ratings from side and back sleepers weighing up to 230 pounds, and stomach sleepers under 130 pounds. That said, some of our testers found the mattress either too soft or too firm. We suggest a different model from Helix’s standard hybrid collection if medium firm isn’t your ideal firmness level.
We found the Midnight performed well for motion isolation and pressure relief, two testing areas where hybrids often struggle. At the same time, the mattress is responsive enough to resist deep sinkage when you move across the surface, and the reinforced perimeter helps ensure decent edge support. You may notice some initial off-gassing odor, but our tests suggest these smells will dissipate in a day or two.
The Midnight carries a below-average sticker price for a hybrid model and Helix offers free ground delivery to all 50 states. Your purchase includes a 100-night trial period. You may return the mattress at any point during the trial for a full refund and Helix will cover the shipping charges. For those who keep their Midnight, the mattress is covered under a 10-year manufacturer’s warranty.

Product Details
The DreamCloud is a luxury hybrid that combines the coil support of a traditional spring with the deep contouring of an all-foam mattress. Our team was impressed with the DreamCloud’s performance in areas where hybrids tend to fall short, such as pressure relief and motion isolation. The cushioning comfort layers and sturdy support system also made the mattress popular with our testers across different weight and sleep position groups.
What It’s Made of
Soft foam quilted into a pillow-top gives the DreamCloud a plush, adaptive feel. By comparison, most of the hybrids we’ve tested feel firmer and more rigid on the surface. Secondary foam layers add cushioning, while a pocketed coil support core stabilizes the mattress and prevents you from sinking too much.
The mattress is encased in a cashmere-blend cover with cooling and moisture-wicking properties. We found this fabric effectively offset heat absorption in the foam layers – our temperature control tests revealed minimal heat buildup. At 14 inches thick, the DreamCloud is not only a high-profile mattress but also one of the thickest mainstream mattresses we’ve tested firsthand.
How It Performed
We’ve rated the DreamCloud as a medium firm, or a 6 on our 10-point firmness scale. This mattress’ body contouring and overall support should appeal to anyone who needs a balanced feel to sleep comfortably. During our sleeper tests, the DreamCloud earned its most favorable ratings from side sleepers weighing at least 130 pounds, though back and stomach sleepers across all weight groups gave the mattress a rating of “good” or better.
Minimal pressure buildup was evident when we tested the DreamCloud for pressure relief. This can be attributed to its thick foam layers. Motion isolation was another highlight for our team. Unlike most hybrids, which feel responsive and bouncy to a degree, the DreamCloud eliminated most transfer on the surface. Our testers detected little to no movement from the other side of the mattress.
The DreamCloud Mattress is priced competitively for a hybrid model and ground shipping is free for all buyers in the contiguous U.S. The company’s sleep trial extends for an entire year, giving you plenty of time to test out the mattress and come to a decision. If you keep the DreamCloud, you’ll also receive a lifetime warranty that covers structural defects for as long as you retain ownership of the mattress.
“The Nectar’s foam construction and medium firm feel offer a great balance of pressure relief and support at an affordable price-point. A year-long sleep trial is one of the longest we’ve come across and sweetens the deal if you’re shopping on a budget.” – Lauren Fountain, Senior Product Editor

The Nectar Mattress is a firmer-than-average memory foam model that excelled during our pressure relief tests. The mattress also has an approachable price-point that should appeal to shoppers on a budget.
What It’s Made of
A 2-inch comfort layer ensures even contouring from head to toe, which our side-sleeping testers found improved spinal alignment and alleviated pressure points in the process. Meanwhile, the medium firm (6) feel was not too soft for testers who weigh under 230 pounds. Beneath the comfort layer is a 3-inch transitional layer made of polyfoam, followed by a 7-inch support core of high-density polyfoam. A cover containing cooling fibers encases the mattress.
How It Performed
Memory foam is known for trapping heat and feeling uncomfortably warm, but we found the Nectar Mattress mitigates bothersome heat retention thanks to the phase change material layer. Motion isolation is another strong point. The bed’s three foam layers reduced movement transfer significantly during our motion isolation tests. You and your partner should sleep soundly without disruptions when one of you changes positions or gets up in the middle of the night.
In addition to the affordable pricing, Nectar further incentivizes value seekers with free shipping anywhere in the contiguous U.S. and a sleep trial that spans 365 nights in length. The mattress is backed by a lifetime warranty covering structural and manufacturing defects for as long as you retain full ownership.

Product Details
Many of the luxury mattresses we’ve tested carry expensive price-points reflective of their materials and designs. The Saatva Classic, on the other hand, is a high-end mattress that falls well below average in terms of cost. Free White Glove delivery and a year-long sleep trial should sweeten the deal if you’re seeking a high-value bed.
What It’s Made of
The Classic is available in three firmness levels: soft (3), medium firm (6), and firm (8). All three share the same general construction, which begins with a Euro-top cover. Layers of adaptive foam and fiber fill give the mattress an invitingly plush surface, while a strip of dense memory foam cradles the lower back. Even on the firmest model, we noticed deep cushioning from these layers. The pocketed minicoil transitional layer maintained an even surface for our bodies, resulting in minimal sinkage for most of our testers.
The support core contains recycled-steel hourglass coils with a low gauge of 13, ensuring robust support. You can choose between an 11.5-inch mattress with 4-inch coils or a 14.5-inch model with 7-inch coils. We recommend the latter for people weighing more than 230 pounds, though our tests showed both designs are highly supportive. A cover made of breathable organic cotton encases the entire mattress.
How It Performed
The most comfortable version of the Saatva Classic for any given person depends on their body weight and primary sleep position. During our hands-on tests, the soft model was most popular among our side sleepers weighing up to 230 pounds and our back sleepers under 130 pounds. This model contours very closely to cushion your body and reduce pressure along your spine. The firm design provided adequate reinforcement for our back and stomach sleepers weighing at least 130 pounds, as well as our side sleepers over 230 pounds. If you’re looking for a balance of conforming and support, we recommend the medium firm. We found this the most balanced design of the three.
The Saatva Classic excelled at cooling when we tested it for temperature control, and our thermal sensors picked up very little heat retention. This was especially true of the medium firm and firm models. We also measured minimal perimeter sinkage on these models during our edge support tests, and most of us could move across them without sinking too much. The soft Classic outperformed the firmer models in other areas, including motion isolation and pressure relief.
Saatva is one of the only online mattress brands that offers free White Glove delivery to all customers in the contiguous U.S. This service includes full assembly in a room of your choice and removal of your old mattress and/or foundation at no extra charge. You’ll also receive 365 days to test out the Saatva Classic before deciding whether to return it or keep it, as well as a lifetime warranty.
“Three of our testers have slept on a WinkBed for at least a year, and they’ve all raved about how sturdy and supportive the bed feels without sacrificing cushioning. They felt little to no soreness in the shoulders and hips, but also felt like their lower backs were well supported.” – Tom Ryan, Head of Product Testing

Product Details
The WinkBed is a versatile hybrid available in four different firmness levels. Our team tested all four designs in our lab, and each person found at least one firmness that felt comfortable and sufficiently supportive. Thanks to the generous WinkBeds return policy, you can exchange your initial firmness for a softer or firmer model if you aren’t happy with your first choice.
What It’s Made of
Standard WinkBed models include the Softer (4), Luxury Firm (6), and Firmer (7). These mattresses begin with Euro-top layers containing adaptive foam, followed by an additional foam layer. We found that the cushioning level varied by firmness, but all three standard designs contoured evenly to distribute our weight and reduce pressure in sensitive spots like the shoulders and hips. The fourth option, WinkBed Plus (8), swaps out the second layer for responsive latex, resulting in a more supportive feel. WinkBed has specifically designed the Plus for people who weigh more than 230 pounds, and this claim was affirmed by most of our testers in this weight range.
All four WinkBed models contain pocketed coil support cores. The coils are divided into zones based on where people carry more weight. Our testers noticed significant pushback around the torso and hips and a gentler feel beneath the head, shoulders, and legs. Extra reinforcement stabilizes the perimeter to reduce sinkage when you get in and out of bed. Thanks to this configuration, most versions of the WinkBed aced our edge support tests.
How It Performed
We found that the Softer WinkBed conforms more closely than its firmer counterparts. This mattress was most popular among our side sleepers up to 230 pounds and our back and stomach sleepers under 130 pounds. The Luxury Firm will likely meet your needs if you’re seeking a balance of cushioning and support. This model earned stellar ratings from our side, back, and stomach sleepers across most weight groups. If you weigh more than 230 pounds and sleep on your back or stomach, then the Firmer or WinkBed Plus should provide adequate support.
Our testing also indicates the mattress is a good option for hot sleepers. This is thanks to the breathable Tencel cover and a coil system that promotes steady air circulation throughout the interior. Other strengths of the mattress include strong edge support, good ease of movement across the surface, and above-average motion isolation.
WinkBeds offers a 120-night sleep trial and a lifetime warranty against workmanship and manufacturing defects. Shipping is free within the contiguous U.S.

Product Details
The Leesa Sapira Hybrid checks all of the important boxes for couples and co-sleepers. Thick foam comfort layers absorb movement and minimize motion transfer, breathable materials help you and your partner stay cool, and the sturdy coil system ensures robust edge support and a responsive surface. Competitive pricing further sweetens the deal if you’re shopping with a limited budget.
What It’s Made of
The Sapira Hybrid’s topmost layer is composed of adaptive polyfoam ventilated with small holes, allowing air to circulate directly beneath the surface. Memory foam and transitional polyfoam layers provide additional cushioning. The mattress has a medium firm (6) feel, so you’ll notice some plushness when you get into bed but strong overall support as your body settles into the mattress.
Pocketed coils and high-density base foam make up the support core. The perimeter coils are reinforced to prevent excessive sinkage when you sleep or sit along the edges. A breathable knit cover styled with Leesa’s signature stripe pattern encases the mattress.
How It Performed
Our tests show the Sapira Hybrid is a good match for side sleepers weighing at least 130 pounds, and back and stomach sleepers weighing less than 130 pounds. We also found the mattress sleeps exceptionally cool. This can be attributed to the breathable cover, aerated top layer, and steady airflow throughout the coil system. None of our testers noticed excessive heat retention despite the thick foam layers.
Other performance areas where the Sapira Hybrid excelled include motion isolation, edge support, and ease of movement. You may notice some strong off-gassing smells after unboxing the mattress, but these smells should dissipate within a day or two.
An approachable sticker price and free shipping to all 50 states make the Sapira Hybrid a solid option for budget-conscious shoppers, and your order includes two Leesa pillows at no extra cost. The company’s sleep trial runs for 100 nights. You may return the mattress for a full refund during this time frame. Should you decide to keep it, your purchase is further backed by a 10-year manufacturer’s warranty.

The Nolah Evolution 15’s foam hybrid design offers ample cushioning along the spine, while zoned coils prevent uncomfortable sagging. Thanks to these features, we highly recommend the mattress if you struggle with joint or lumbar pain due to spinal misalignment.
What It’s Made of
A Euro-top quilted with polyfoam begins the Evolution 15’s comfort system, giving the surface a plush feel. Underneath is graphite-infused polyfoam that offers cushioning to pressure points. The graphite in this layer is engineered to absorb and dissipate excess body heat. A transitional layer of polyfoam acts as a buffer between the comfort system and coils, preventing you from sinking too deeply.
Pocketed coils in a zoned configuration make up the support core. These coils offer ample pushback to the midsection, where many people carry a disproportionate amount of weight. Extra coils also line the perimeter of the mattress to reinforce the edges. The coils rest on a polyfoam base layer for extra stability. A cover made from ArcticTex fiber, which is engineered for cooling, encases the mattress.
How It Performed
The Evolution 15 comes in three firmness levels – medium (5), medium firm (6), and firm (7) – and its performance depends on the feel you choose. Our testing found the plushest model suitable for side sleepers up to 230 pounds and back sleepers weighing under 130 pounds, who often prefer extra cushioning for pressure points. The medium firm feel was the most versatile, appealing to our side sleepers over 230 pounds, back sleepers up to 230 pounds, and stomach sleepers between 130 and 230 pounds. Our back sleepers who weigh at least 130 pounds and stomach sleepers over 230 pounds enjoyed the firmest model’s even contouring.
Depending on the firmness level, the Evolution 15 varied in performance across our testing criteria. The softest model absorbed most movement transfer and noise, making it a great choice if you share the bed with a restless sleep partner. Couples who value responsiveness for sex may prefer the two firmer models, which earned higher marks in our ease of movement and edge support tests. All models performed exceptionally well in our temperature regulation tests, thanks to the breathable cover and airflow through the support core.
Seven sizes, including a split king, are available. Nolah offers free shipping to all customers living in the contiguous U.S. You can test the Evolution 15 with a 120-night sleep trial, during which you can return the mattress anytime after the 30-night break-in period. If you decide to keep the mattress, it is backed by a lifetime warranty.

Product Details
Mattresses made with foam layers tend to trap heat on the surface, but the Brooklyn Bedding Aurora Luxe is a notable exception. Our temperature control tests detected minimal heat retention, which we’ve attributed to the phase change material (PCM) infused in the Aurora Luxe’s cover and comfort layer. A coil system that generates steady airflow provides additional cooling. Even if you’re an exceptionally hot sleeper, this mattress should keep you cool and comfortable throughout the night.
What It’s Made of
The Aurora Luxe comes in three firmness levels: medium soft (4), medium firm (6), and firm (7). All three feature a top layer made from CopperFlex polyfoam, a proprietary foam that’s more responsive while still adding cushioning. The foam is infused with copper engineered to conduct heat away from your body and phase change material meant to regulate temperature. Next is a layer of responsive TitanFlex foam that prevents you from sinking excessively. For an additional fee, you can upgrade your mattress with an extra foam layer in the comfort system. This layer is known as the “Cloud” pillow-top, and will make your sleep surface feel a bit softer.
Depending on the firmness option you choose, the comfort system’s final layer differs. The two softer models have an adaptive gel-infused memory foam layer that acts as a buffer between your body and the coil support core. Meanwhile, the firmer option has a second layer of TitanFlex foam to help you maintain healthy sleep posture.
The support core uses pocketed coils in a zoned configuration. Thinner coils cushion your legs and shoulders while thicker ones provide pushback to your midsection and bolster the mattress perimeter. A polyfoam base layer prevents the coils from shifting, and a fabric cover with phase change material encases the mattress.
How It Performed
Our testers noted that all Aurora Luxe models offered a great balance of cushioning and support, but each provides distinct benefits depending on your sleep needs and preferences. Our side and back sleepers who weigh under 130 pounds enjoyed the softest model’s plush feel. The medium firm model was the most versatile and balanced. It performed best among side sleepers between 130 and 230 pounds, as well as back and stomach sleepers under 130 pounds. If you are a back or stomach sleeper weighing at least 130 pounds, you may prefer the firmest model’s even support.
All three models excelled in cooling but also performed well in other key categories. Our testing found the mattress alleviates pressure points very well across firmness levels. We also recommend all models for couples who don’t want to choose between a mattress that isolates motion and one that’s responsive for sex. However, we recommend opting for the softer model if you prioritize motion isolation.
Shipping is free if you live in the contiguous U.S., and Brooklyn Bedding offers a 120-night sleep trial to test the mattress. You can return the mattress for a full refund anytime after the 30-night break-in period. If you decide to keep the Aurora Luxe, it is backed by a 10-year warranty.

Many people experience upper or lower back pain because their mattress sinks excessively around the midsection. The Bear Elite Hybrid remedies this with a robust support system consisting of zoned transitional polyfoam and robust pocketed coils. Adaptive memory foam cushions the surface, contouring evenly for added pain relief, and you can choose from three firmness levels based on your body type and primary sleep position.
How It Performed
The Elite Hybrid’s medium (5) design earned its most favorable ratings from our side and back sleepers under 130 pounds. This model contours closely to the body. Despite the zoned transitional foam, you’ll feel a close “hug” from the mattress. Our testing team found the medium firm (6) design to be the most balanced of the three firmness options. You can expect gentle conforming and even overall support from this model. If you need extra reinforcement and minimal cushioning from your sleep surface, we recommend the firm (8) Elite Hybrid — this model was popular among our back and stomach sleepers weighing more than 230 pounds.
Temperature control proved to be a strong performance area for the Elite Hybrid during our tests. Thermal sensors detected minimal heat buildup, especially on the two firmest models, and none of our testers reported uncomfortable heat retention. We also found the perimeter stable when testing the mattress for edge support, and the surface was responsive enough to facilitate movement without excessive sinkage or resistance.
What It’s Made of
The Elite Hybrid’s comfort system consists of gel-infused memory foam over transitional polyfoam. Both layers provide even contouring to distribute your weight and alleviate pressure along the spine. The transitional layer is divided into five firmness zones, so you’ll feel more pushback beneath your midsection and gentler cradling for lighter areas of the body.
Pocketed coils and dense base foam make up the support core. Thicker coils line the perimeter to protect the edges of your mattress from sinkage when you get in and out of bed. The cover is composed of Celliant-blend fabric woven with phase change fibers intended to dissipate heat on contact, so the surface should remain cool to the touch at all times.
The Elite Hybrid is competitively priced and Bear offers free ground shipping throughout the contiguous U.S. The company’s sleep trial runs for 120 nights. If you decide to keep the mattress after the trial ends, you’ll also receive a lifetime warranty against structural defects.
“Our testers found the Birch Mattress’ latex hybrid design to be responsive yet adaptive, so you should receive ample cushioning for sore spots and robust support to keep your body on an even plane.

Back pain often requires a mattress that cushions the body while maintaining even support. The Birch Mattress contains a latex comfort layer, so your body shouldn’t sink too much around the midsection. This can alleviate pain in your shoulders and lower back.
What It’s Made of
A comfort system of moisture-wicking wool over ventilated Talalay latex makes the Birch feel exceptionally cool on the surface. We detected low heat retention when testing the mattress for temperature control, and even the hot sleepers on our team felt comfortable lying on the surface. Pocketed coils promote airflow for added breathability. We also noticed strong responsiveness, which can be attributed to the naturally responsive latex and generous coil pushback. An organic cotton cover encases the mattress.
One appealing aspect of the Birch is its eco-friendly design. A Rainforest Alliance certification indicates rubber trees used to create the latex are sustainably grown, while an eco-INSTITUT certification ensures the material has been evaluated for harmful emissions. Additionally, Birch has been recognized for humane treatment of the sheep used to extract wool in the fire barrier.
How It Performed
We’ve tested quite a few latex hybrids in recent years, as these mattresses have proven popular with sleepers seeking pain and pressure relief who dislike the body hug of foam. The Birch Mattress is one of the most balanced latex hybrids we’ve encountered. Our testers have noted consistent responsiveness and ease of movement across the surface, but also closer contouring and deeper cushioning compared to other beds with latex comfort layers.
Our sleeper testing ratings for the Birch were positive across the board. The mattress was particularly popular with side sleepers on our team weighing at least 130 pounds, back sleepers between 130 and 230 pounds, and stomach sleepers over 230 pounds. Due to its breathable components, the Birch also performed well during our temperature control tests and displayed minimal heat retention.

How We Test: Rigor, Data, and Sleeper Feedback
Our team uses an objective rating system that takes all important sleeper needs into consideration. By taking a holistic look at mattresses, we can determine the pros and cons of each model in order to help you make the best purchasing decision.
We understand the connection between sleeping on a mattress suited to your sleep style and getting high-quality sleep each night. Our team personally evaluates each mattress in our Seattle-based Test Lab using a four-step process, which you can read about in detail below.
Construction analysis: Mattress construction plays a major role in how the bed feels and performs. To kick off our hands-on tests, we’ll perform a detailed analysis of the mattress’ design and take note of manufacturer specs such as firmness, thickness, and layer density.
Product testing: Our team runs each mattress through the same series of hands-on tests, during which we’ll use various tools and technology to evaluate each model for six performance categories. These tests help us calculate ratings for important qualities like pressure relief, temperature control, and edge support.
Field testing: We rely on feedback from field testers, members of our team who use mattresses in their own home over the course of several weeks. Field testing data helps us understand how mattresses perform night after night.
User testing: Real mattress owners also influence our product ratings. We collect data from surveys and mattress reviews, then weigh this data against our own findings to ensure accuracy and inclusivity.
Who Should (and Shouldn’t) Sleep on a King Size Mattress?
A king-sized mattress can anchor your bedroom and maximize your sleeping space, but this size isn’t for everyone. We find that king mattresses are ideal for:
- Couples: Ample space so both partners can enjoy undisturbed sleep.
- Families: Perfect for co-sleeping and lazy weekends.
- Pet owners: Giving pets space without crowding their humans.
- Tall sleepers: Extra width for those who like to spread out.
On the flip side, a king mattress may not suit:
- Singles: May be excessive for those sleeping solo.
- Small spaces: Can overwhelm tighter rooms.
- Budget shoppers: Typically pricier than smaller mattresses.
- Frequent movers: Can be challenging to transport.
Are There Different Kinds of King Size Mattresses?
King mattresses come in various styles, each with slightly different dimensions. A standard king is 76 inches wide and 80 inches long, making it 16 inches wider than a queen. A California king adds 4 inches in length, while a split king pairs two twin XLs to allow for separate firmness levels in one bed. Alaskan and Texas kings are some of the most spacious oversized mattresses on the market.
| Size | Dimensions |
|---|---|
| King | 76″ x 80″ |
| Split King | 76″ x 80″ |
| California King | 72″ x 84″ |
| Alaskan King | 108″ x 108″ |
| Texas King | 80″ x 98″ |
What to Consider When Shopping For a King Mattress
While many people choose a king mattress for its size, it’s important to remember that mattress shopping is about finding the right combination of comfort, support, and value. To make the process a bit easier, we’ve put together the following list of factors to consider when shopping for a king mattress.
Your Sleeping Position and Weight
Side sleepers tend to prefer a softer bed that conforms under their hips and shoulders, while back and stomach sleepers benefit from firmer mattresses that offer increased support. If you weigh under 130 pounds, you might gravitate towards a plusher surface, while if you’re over 230 pounds, a firmer option might be more suitable.
Mattress Type and Height
Several mattress types dominate the market, each with unique advantages:
- Innerspring: Bouncy with good airflow, these are often the most budget-friendly king mattresses.
- Foam: Conforming and pressure-relieving, the performance of an all-foam king mattress depends on the types of foams used in its construction.
- Latex: Latex kings are responsive and durable beds popular with eco-conscious shoppers, but can be expensive.
- Hybrid: Many of our favorite king mattresses are hybrids that combine the benefits of an innerspring core with layers of foam or latex.
The height of a mattress also affects its aesthetics and performance. When shopping for a king mattress, consider if a taller or shorter design suits your preferences in terms of style, price, weight, and the ease of getting in and out of bed.
Transportation and Bedroom Space
Before buying a king mattress, keep in mind that this bed size is inherently large and heavy. Make sure that your bedroom has enough space to accommodate a king mattress and consider how you’ll get it into your bedroom. Pay special attention to any narrow hallways and doorways and be sure to enlist a friend or two for help.
Edge Support and Motion Isolation
Two of the most important performance factors for a king mattress are edge support and motion isolation. Edge support refers to the mattress’s strength and stability on its sides, important for maximizing sleeping space and preventing sagging at the edges. Motion isolation reduces the likelihood that you’ll be disturbed by a co-sleeper’s movements.
Budget and Pricing
King mattresses typically carry a heftier price tag than smaller sizes. Factors influencing the cost of a king include material, quality, brand, and added features. If you’re shopping on a budget, keep your eyes out for discounts, promotional bundles, and seasonal sales.
Trials, Returns, and Warranties
A king mattress can be a significant investment, so understanding trials, returns, and warranties is crucial. Trials allow a risk-free way to try a mattress before commiting. Returns allow you to send it back if you’re unsatisfied, and warranties protect against manufacturing defects. Ensure these policies are transparent and suit your needs when hunting for your perfect king mattress.

Frequently Asked Questions
A king mattress is typically 76 inches wide and 80 inches long. Height and weight vary, but these beds are usually around 9 to 12 inches tall and weigh over 100 pounds.
The added space of a king mattress makes it ideal for couples seeking more space, families who co-sleep or hang out in bed, pet owners wanting room for their furry friends, and taller individuals who appreciate the added width.
The price of a king mattress can vary significantly based on its materials, brand, and added features. On average, you can expect to spend anywhere from $900 to over $2000 on a king mattress. Because these beds can be a big investment, it’s wise to research and set a budget before making a purchase.
The Family XL, at 144″ wide and 84″ long, is the biggest oversized mattress on the market. While the Alaskan King is often noted for its generous 108″ x 108″ dimensions, the Family XL surpasses it in width by an impressive 3 feet. Oversized options like the Family XL can be challenging to find, and require custom frames and bedding.
A king’s ridge refers to a hump that can form in the center of a king mattress that can develop in outdated or low-quality mattresses as they begin to sag in several areas. To keep the king’s ridge at bay, invest in a high-quality mattress, regularly rotate your bed, and don’t forget to replace it every 7 to 10 years.
