Top 10 Best King Size Mattresses

1. The Puffy (Editor’s Choice)

Puffy original

Overview

  • Material: Gel Memory Foam and High-Density Polyfoam
  • Height: 10 inches
  • In-Home Trial: 101 nights
  • Warranty: Lifetime

If your idea of the best king size mattress involves lying down each night on a bed that feels as though it was crafted from clouds, then the Puffy mattress is a great place to begin. This sensational all-foam bed features a combination of different materials to transform your sleeping experience.

Features

Probably one of the best memory foam king size beds on the market today, the Puffy includes a mixture of gel memory foam to keep you cool, and high-density polyfoam. The polyfoam section of this mattress comes with a slightly tougher firmness level. Therefore, you can get the support you need without the springs. Additionally, the Puffy mattress gives you an excellent level of pressure relief, spine alignment, and support in one neat package!

The Puffy mattress has been around for a few years now, first hitting the US market in 2017. The company designed this king size mattress to suit the needs of modern sleepers who don’t want to compromise on either performance or comfort. The Puffy brand even put its bed through dozens of different tests to help create the ideal sleep system, even for people with back pain.

Another great bonus of the Puffy bed is that all of the products made by this company are designed and built in the USA. The mattress foam included in each bed is also CertiPUR-US certified. That means you can rest assured that you’re getting no less than the highest standard of amazing bedding comfort. On top of that, Puffy helps you feel good about the purchases you make by partnering with a bunch of excellent non-profit companies, too.

If you’re looking for a bed that’s designed for all sleepers and can be placed on any surface, including adjustable frames and slats, this is the bed for you. On the downside, if you’re after something that makes you feel like you’re sleeping on top of your bed, rather than in it, then Puffy isn’t your best bet. The softer and sinkable nature of the bedding makes it less appealing for those who like firm beds.

Another drawback is that it’s not particularly good at handling stomach sleepers. There’s a good chance that your hips and stomach will sink into the mattress during the night. Hence, this could leave you with some serious back pain.

Pros:
  • Excellent for back and side combination sleepers with plenty of softness
  • Great for those who want a unique memory foam experience
  • Cooler sleeping temperature than most memory foam mattresses
  • Ideal for removing any pesky pressure point aches from your joints
  • Available in a range of sizes, including King size
  • The brand offers a matching Puffy bedding for your mattress
  • Great for social consciousness
Cons:
  • Not available everywhere
  • Doesn’t have much bounce for those who like a firmer bed
  • Not ideal for stomach sleepers

2. The Saatva (Luxury Choice)

Saatva Classic

Overview

  • Material: Innerspring Coils and Memory Foam
  • Height: 11.5 inches
  • In-Home Trial: 120 nights
  • Warranty: 15 years

Saatva is a name in the bedding industry that has gained a lot of attention over the years. If you’re looking for a sensational experience – from customer service to sleeping, then you can rest easy with Saatva. The Classic King mattress is a hybrid type that blends innerspring components with the comfort of a foam layer.

Features

The combination of foam and springs in the Saatva means that you get all of the extra comfort that you need from foam, with the durability and support of springs. Like with Puffy, every Saatva mattress is made to order in the USA. Plus, there’s only the highest quality of materials in these beds, which is one of the reasons why they’re a little more expensive than other bed-in-a-box brands.

To create the classic, five-star mattress from the hybrid range, Saatva took all of the key features found from luxury mattress companies around the world. There’s a relaxing pillow top on the surface that helps to eliminate pressure points and take your aches and pains away. It also comes with perimeter edge support, so you can take full advantage of every inch of your mattress.

Saatva King beds are designed with Spinal Zone technology, which protects your back from any discomfort. In addition, the durable steel cones will keep your investment from wearing out, no matter how often it is used. Speaking of the coils in the Saatva Classic, it’s also worth noting that they’re individually wrapped. Hence, you’re not going to have to deal with any extra inconvenience.

Moreover, Saatva offers three firmness options to choose from, so you can find the bedding option that’s best for you. However, most customers will choose the luxury firm choice, as it’s suitable for a majority of sleeping styles. If you love the bounce of a spring mattress, then you’re going to enjoy the experience that you get with Saatva. On the other hand, if you’re searching for a hugging and comforting feeling – as with memory foams, this isn’t the ideal option.

Additionally, the Saatva beds are a bit costly than some of the other hybrid options on the market, but that’s because you’re getting very high-luxury materials.

Pros:
  • Suitable for a wide range of sleepers
  • Great for those who want the extra support of spring
  • The hybrid mattress combines comfort and support with durability
  • Excellent for combination sleepers who like to sleep in any position
  • Available in a selection of sizes, including King size
  • Excellent high-quality materials throughout
Cons:
  • Doesn’t offer a memory foam experience as you would get from an all-foam bed
  • Not ideal for those on a very tight budget
  • A little heavier than some mattresses

3. Tuft and Needle (Best Value)

Tuft & Needle Original

Overview

  • Material: Open-Cell Foam with Graphite and Cooling Gel
  • Height: 10 inches
  • In-Home Trial: 100 nights
  • Warranty: 10 years

Tuft and Needle was founded back in 2012. The company has been growing rapidly over the last few years. Today, it’s one of the most popular brands for bed-in-a-box solutions that you can get. The brand currently has a range of options to choose from, including the Mint, the Hybrid, and the Original.

Features

One of the great things about the Original mattress from Tuft and Needle is that it comes in a range of sizes. You can choose between the California King, Standard King sized, and more. In addition, you can get your bedding from the Tuft and Needle Company. According to the brand, although they offer a money-back guarantee if you want to return your bed, over 95% of its customers stick with their purchase.

The Original mattress is designed to be universally comfortable and supportive, no matter which sleeping position you might be in. This memory foam mattress is made with two layers of open-cell memory foam, as well as added elements of cooling gel and graphite. The extra components of the gel memory foam and graphite help to regulate your temperature in every sleeping position.

Every aspect of the Tuft and Needle Original mattress is designed to give you a perfect night’s sleep – from the cover which is hypoallergenic, to the luxury materials throughout. The mattress ships straight to your door as soon as you click the order button. Plus, they all come with a 100-night sleep trial to give you extra peace of mind. The cover of the mattress is also included in the warranty, which lasts for ten whole years!

As memory foam mattresses go, the Tuft and Needle is one of the most reliable and has some of the best temperature regulating support that we’ve found. Medium firm foam means that you don’t sink too deeply into the mattress. However, we still wouldn’t recommend this product for pressure relief if you sleep on your stomach, as you’re likely to sink too far into the memory foam.

Another major downside of the Tuft and Needle is that it isn’t going to be a good choice for heavier sleepers. Chances are you’ll sink through into the softer layers below and get none of the firmer benefits.

Pros:
  • Available in a lot of sizes including King size and California King
  • Excellent pressure relief for back and side sleepers
  • Designed to manage temperature regulation with gel memory foam and graphite
  • No steel coils or internal elements to worry about
  • Fantastic customer service with a 100-night sleep trial
  • 10-year warranty included on bed and cover
Cons:
  • Not ideal for stomach sleepers
  • Not supportive for heavier sleepers

4. Layla Sleep (Best Hybrid)

Layla Hybrid

Overview

  • Material: Memory Foam and Pocketed Coils
  • Height: Approximately 13 inches
  • In-Home Trial: 120 nights
  • Warranty: 10 years

The original Layla is a double-sided mattress, which is excellent if you’re looking for a bed that’s durable enough to stand the test of time. After all, when you can flip a mattress over, there’s less of a chance that you’re going to be left with an indent. In this particular King size mattress review, we’re looking at the Hybrid from Layla. It’s an innovative multi-layer bed that shares the flappable nature of the original Layla.

Features

The great thing about this mattress is that it has two different sides with varying levels of firmness depending on your needs. One side is extra soft, ideal if you want a little more of a hug from your mattress. On the other hand, there’s also a slightly firmer side. If you’re looking for a perfect guestroom bed, this could definitely be it, as your guests will be able to create the sleeping experience that’s best for them.

The cushiony side of the mattress is quite soft, which makes it a good choice for someone who wants a mattress with a spring core but also prefers the sinking softness of traditional memory foam. On the other hand, the firm side of the mattress is much tougher. Still, it comes with enough support to handle stomach sleepers who don’t want their hips to sink through their bed.

Furthermore, the versatile nature of the Layla Hybrid means that you can potentially have a different sleeping experience every day. That is if you don’t mind lugging a heavy mattress over from one side to another. The firm side offers an increased amount of support where you need it most, while the soft side gives you more supple softness. If you’re looking for mattresses – king size and above, this is a great choice, too. Similar to some of the other options we’ve covered, there’s a California King option as well.

The Layla also comes with a warranty of 10 years and a 120-night trial period which is slightly longer than you get elsewhere. One thing to note though, both sides of this mattress are very extreme in their softness and firmness. If you want something that’s right in the middle, you’re out of luck.

Another problem with the Layla is a common issue with many memory foam and hybrid mattress options – its off-gassing. Although it’s one of the top mattresses on the market, the smell is pretty bad and may last for several days.

Pros:
  • Comes with a warranty for 10 years and a 120-night money-back guarantee sleep trial
  • Different sides to suit different sleeping types
  • Flippable, you can be certain that it’ll last for longer
  • Combination of memory foam mattress and spring
  • Range of sizes including California King
  • Excellent comfort and support with strong motion isolation
Cons:
  • Quite a lot of off-gassing
  • Both sides are quite extreme in their softness and firmness rating

5. Zenhaven (Best Latex)

Zenhaven Saatva

Overview

  • Material: Latex and Wool
  • Height: 8.75 inches
  • In-Home Trial: 120 days
  • Warranty: 20 years

This is another mattress by the Saatva brand, although it takes a slightly different approach to the top bed that we covered above. Like the Saatva Classic, the Zenhaven is a fantastic bed with a lot of quality materials throughout. However, the main difference here is that you’re getting an all-natural Talalay latex mattress that offers comfort for a range of people.

Features

Taken from trees, the material in the Zenhaven is totally natural, so you don’t have to worry about exposing yourself to anything dangerous. Additionally, the latex responds to every curve of your body just like memory foams. The Zenhaven mattress even has an organic wool layer for extra comfort. If you’re looking for perhaps the most natural sleeping experience you can get – this might be it.

The Zenhaven’s exclusive materials are unlike anything else that you’ll find on the market. What’s more, this latex option is a lot better at handling temperature regulation and heat, as compared to many memory foam-style beds. Hence, you don’t have to worry about waking up in a pool of sweat.

Another big bonus of the Zenhaven brand is that it’s well-known for its sensational customer service. You can expect a fantastic level of support, whether you’re asking questions or returning your mattress. Zenhaven will even take your old mattress away for you for free if you’re done with it, so you don’t have to think about recycling.

Furthermore, the Zenhaven is naturally supportive and excellent for conforming to your body. Delivering the perfect combination of healthy support and luxurious comfort, the open—cell structure of the latex allows the air to circulate freely around as you sleep.

Pros:
  • Fantastic customer service from start to finish, including mattress removal
  • Excellent for back pain and pressure relief
  • Great for a range of sleeping styles – side, back, and stomach
  • Better support than most memory foam options
  • Natural materials throughout, no exposure to chemicals
  • King size and other options available
  • 20-year warranty included
Cons:
  • Not ideal for those who have trouble lifting heavy objects
  • Prices are a little high for some customers
  • Edge support isn’t great
  • Quite firm if you’re looking for a memory foam mattress style sleep

6. Nectar Original (Best for Side Sleepers)

 

 

Nectar Original

Overview

  • Material: Memory Foam
  • Height: 11 inches
  • In-Home Trial: 365 nights
  • Warranty: Lifetime

Another contender for the best king size mattress is the exceptional Nectar Original. This is one of the best king size memory foam mattress options that we’ve seen, offering a perfect blend of comfort and support. There is a range of Nectar King size mattresses to choose from, but in this case, we’re just looking at the Original. You can buy foundations and adjustable base options from Nectar, too.

Features

Nectar’s memory foam mattresses are available in a range of sizes, from 80 inches long King size mattresses to Twin XL options. The Original is made with a variety of award-winning layers. There’s a quilted memory foam cover at the top of the mattress that’s designed to deliver sinkable softness. Underneath that, you get a layer of gel memory foam that helps to distribute body heat more effectively. It allows you to regulate your temperature through the night.

One of the best things about the Nectar mattress is how good it is at dealing with motion transfer. If you sleep with a partner, then you can rest assured that your other half won’t feel any of your tossing and turning. Another excellent feature of the Nectar king size mattresses is that although they’re a full memory foam option, they also come with a reasonably low price tag and a significant level of support.

Like other mattress leaders, such as Tuft & Needle, the Nectar bed can offer a good level of comfort and support at the same time. However, it may still be a little too soft for people who want the pressure relief that comes with a spring or hybrid mattress. Additionally, the Nectar mattress does have some off-gassing issues that are common with a lot of foam mattresses.

What’s more, because it isn’t quite a firm mattress, the Nectar is great for sleeping on your slide. However, it might not be as good as a box spring with a stronger base layer if you often sleep on your front or back.

Pros:
  • Award-winning layers throughout
  • Excellent gel memory foam components
  • CertiPUR-US certified
  • Designed for excellent comfort if you’re a side sleeper
  • Great full memory foam experience
Cons:
  • Not ideal for front or back sleepers
  • Some issues with off-gassing
  • Not the firmest mattresses on the market

7. Helix Sleep

Helix Sunset

Overview

  • Material: Memory Plus Foam and Pocketed Coils
  • Height: 12 inches
  • In-Home Trial: 100 nights
  • Warranty: 10 years

The Helix mattress is made from a selection of coils and foams. One of the best things about this mattress is that it’s designed to suit everyone, no matter what your body type or sleeping preferences are. The Helix comes with a 10-year warranty, a 100-night sleep trial, free shipping, and a bunch of other great features to look forward to.

Features

There’s a wide variety of Helix mattresses in the Standard collection, starting with the Sunset that offers excellent side sleeper support and a softer feel, moving onto options like the Moonlight, with back and stomach support. If you need a firmer type of mattress, then you can also look at the mid firmness level alternatives from the brand. These likewise come with body contouring performance, though they’re a little firmer.

Finally, for those who need a firmer level of support, there are two extra choices to choose from, each with the 80 inches wide options that you want from a King-sized mattress. Additionally, mattresses from Helix Sleep are designed to support a variety of customers. The dynamic foam included in the bed provides all the comfort and pressure relief you could want from the best king mattress. At the same time, there’s a coil section for support and firmness.

When customizing this product, you can also think more carefully about what your mattresses need to give you a better night’s sleep. For instance, you can choose a cool or milder option if you know that you sleep a little hotter. The Helix bed is still a relatively new mattress on the market, and it comes at a reasonable price tag. There’s also a 10-year warranty for peace of mind.

Unfortunately, some reviews of these mattresses suggest that it retains heat quite a lot for a hybrid mattress and not much support for heavier individuals. Even with the choice to get the best king size memory foam mattress or hybrid bed, you still might not find the perfect solution from this company.

Pros:
  • Great motion isolation in the mattresses if you sleep with a partner
  • Range of sizes and styles to choose from, including the 80 inches long king size
  • Warranty of 10 years included
  • A hybrid type of mattress for support and comfort while you sleep
  • Good value price tag for what you get
  • 100-night break-in option to test the pressure relief
Cons:
  • Retains a lot of heat
  • Not ideal if you’re a heavier individual
  • Could require a foam topper to give you the best level of support

8. Nest Bedding Alexander Signature

Nest Alexander Signature

Overview

  • Material: Titanium-Infused Memory Foam and Pocketed Coils
  • Height: 13.5 inches
  • In-Home Trial: 100 nights
  • Warranty: Lifetime

Nest Bedding is another well-known provider of California King and King size mattresses in the United States. There are a range of different gel memory foam, king size mattress options to choose from. Each mattress also comes with things like a 100-night sleep trial and five-star customer service.

Features

The Alexander signature hybrid mattress combines fantastic Titanium-infused memory foam that mimics the cooling properties of gel memory foam. Plus, the support of high-performance pocketed coils. You can ensure that whichever mattress you choose, you’re going to wake up feeling your best. The Alexander signature aims to suit stomach, back, and side sleepers. Additionally, there’s a phase-changing and thermo-regulating fabrics included to promote better temperature.

You can also buy your Alexander Signature Hybrid bed in a range of sizes, including California King, and all of them will be made with eco-friendly materials. Moreover, you can be confident that you’ll have a great level of comfort, without any negative impact to the environment.

Because the Nest top rated king size mattress is designed for sustainability, it’s also one of the best king size mattress for the money options. That’s because you know your memory foam and springs are going to stand the test of time. Known for delivering excellent products that go beyond the basics of gel memory foam, compared to other brands like Tuft & Needle and more, the Alexander is an exceptional choice for a lot of sleepers.

However, there are some downsides, too. For instance, with king-size mattresses, it’s often helpful to have handles on the sides of the bed which you can use for moving your mattress. This isn’t something that you get with this king size model. Another issue is that there isn’t as much motion transfer support as you would get with a full gel memory foam mattress.

Pros:
  • Support and comfort is great for a range of sleepers
  • Beautiful and high-quality construction for luxury king size mattresses
  • Quick delivery and excellent customer service
  • Sturdy design of the king size mattress for heavier people
  • Good pressure relief with the special gel memory foam-style layer
  • Sleep trial included so you can test it first
Cons:
  • Not as much motion isolation as other memory mattresses
  • Not as full as an all-memory foam option
  • No removable cover or handles for lifting the 76 x 80 inches wide mattress

9. Casper Original

Casper Original

Overview

  • Material: Polyurethane and Memory Foam
  • Height: 11 inches
  • In-Home Trial: 100 nights
  • Warranty: 10 years

The Casper Original is one of the first high-comfort bed-in-a-box mattress options that came to the market. This fantastic memory foam mattress comes with everything you need for a good sleep. Available in a range of sizes, including King mattress type, the Casper bed is brimming with features to love.

Features

The high-quality materials ensure that you’ll not only get the support you need, but you’ll also have a bed that will stand the test of time. The Casper Original mattress also offers free delivery and returns. Thus, you don’t have to worry about paying extra to get the right level of comfort. There’s even a 10-year warranty included.

Thanks to Casper’s spinal alignment technology, you’ll certainly get an excellent level of support from your 76 x 80 mattress, regardless of your sleeping style. One great thing about this mattress aside from its warranty and sleep trial, is its superb motion isolation. If you sleep with a partner, then you won’t have to worry about bothering them when you’re moving around on your king mattress.

Also, it’s surprisingly easy to move the Casper king memory foam mattress and it’s pretty good for hot sleeping. Most king size mattresses that are made with memory foam have trouble with eliminating excess heat, even with gel memory foam. However, that isn’t the case with the Casper Original. Moreover, there are no steel coils to worry about, just full foam comfort and pressure relief throughout.

On the downside, although the Casper mattress offers excellent value and performance, for the most part, there have been some complaints about a general lack of support for heavier people. Additionally, it’s not the ideal choice if you like the kind of bounce that comes with springs, as you’ll only feel the memory foam while you sleep.

Another disadvantage of the Casper memory foam mattress is that it’s not one of the most natural beds offered today. Although you do get a great experience throughout, there’s nothing like tree-based latex to make you feel better about the environment.

Pros:
  • Range of king mattress sizes and options to choose from
  • Heat management is better than most gel memory foam beds
  • Excellent free shipping and sleep trial included
  • Fantastic motion isolation, like most memory foam mattresses
  • Good value for money if you’re looking for a king mattress
  • Easy to move and 10-year warranty included
Cons:
  • Limited natural components
  • Unable to provide the right pressure relief for heavier people
  • Not ideal if you like the feel and bounce of spring mattresses

10. Brooklyn Aurora Hybrid

Brooklyn Bedding Aurora

Overview

  • Material: Patented High-Density Foam and Memory Foam
  • Height: 13 inches
  • In-Home Trial: 120 nights
  • Warranty: 10 years

Finally, the Brooklyn Aurora Hybrid is one of the best king size mattresses on the market for a number of reasons. If you’re looking for a top king size option, then you’ll love the experience and feel of the Aurora hybrid mattress. According to the king size mattress reviews that we read, Brooklyn Bedding, like Tuft & Needle, has gone above and beyond to make sure you get a great night’s sleep.

Features

As king mattress options go, the hybrid offers a range of sizes including Twin XL and California King. Hence, you can have everything you need for a great price. This King mattress also comes in three firmness levels, which is uncommon for most memory foam mattresses. The hybrid solution means that you can choose the level of support that you require. Additionally, all of these are comprised of CertiPUR-US certified materials throughout with their own set of unique features.

The CopperFlex foam from Brooklyn Bedding provides a more responsive contouring experience, with targeted pressure points. There are also cooling gel beads that provide more cooling relief than you would typically get from a memory foam mattress.

Brooklyn Bedding’s Aurora Hybrid stands out as being made with some of the most advanced materials that you can find in the market today. There’s a double layer of flexible foam on the top and a base layer that helps you to maintain a better level of stability. Additionally, these hybrid king size mattresses entail greater durability.

Furthermore, the Brooklyn bedding company also ensures that you feel well-served and protected, with a remarkable delivery experience and a reliable 10-year warranty. On the downside, not everything about these mattresses is ideal. For instance, although you’ll get some great pressure management from the Aurora, you won’t have the contouring comfort that comes from most memory foam mattresses.

Additionally, this might not be the ideal bed for heavier people looking for king size mattresses. You might fall through the upper layers too quickly and feel the firm coils beneath.

Pros:
  • Excellent quality mattresses with lots of high-level materials
  • Available in a range of sizes
  • Warranty for 10 years included and a risk-free trial for testing the mattresses
  • Excellent for side sleepers – thanks to the high level of cushioning foam
  • Good for couples because of fantastic motion transfer isolation
  • Ideal for keeping you cool while you sleep
Cons:
  • Not the best option if you want a full memory foam mattress experience
  • Not recommended for heavier people as they’re more likely to sink through
