Our team of Certified Sleep Science Coaches have reviewed 600+ mattresses and accessories for over seven years using proprietary analysis and hands-on testing. We assess each bed for support, cooling, firmness, pressure relief, and more. bedding

I’ll review the best king-size mattresses that could give you room for a partner, kids and even pets. Let’s talk about comfort, durability and more.

Do you want to sleep like a King? The best King-size mattress could make you feel like royalty because it gives you so much extra space to move around! We’ve tested hundreds of beds, and seriously considered around 25 of them when constructing this list. Ultimately, we landed on these 11 as the best King-size mattresses, with something for just about every type of sleeper.

Our expert reviewers chose the Nectar as the best king-sized mattress thanks to its quality materials, pressure relieving plushness, and cooling features.

Our team of Certified Sleep Science Coaches have reviewed more than 600 mattresses, using proprietary analysis and hands-on testing to establish easy-to-understand scores. In addition to an overall score, we measure subscores for support, edge support, cooling, motion transfer, durability, trial period, and warranty.

Because mattress size isn’t exactly a scientific category, we considered how much each of these products costs for a king, then compared that to the overall score. To ensure that we only included high-quality mattresses, we stuck with beds that had an overall score of at least 3.5 out of 5, with seven of them scoring a 4 or higher.

This mattress has a slow-moving feel. If you like mattresses that contour to your body, this could be a great option. The Nectar mattress isolates motion well, which is helpful for people who share a bed with a partner or a pet. It offers plenty of pressure relief for side sleepers who weigh less than 230 lb.

Even though it has cooling gel-infused foam, it’s not the best mattress for hot sleepers. If you tend to overheat at night, you may want to consider getting the Nectar Hybrid instead. It’s not supportive enough for most stomach sleepers. In this position, you may feel your hips sink out of alignment, which can lead to lower back pain. Because it’s an all-foam bed-in-a-box mattress, it has a 48-hour off-gassing period. You’ll need to let the mattress air out for two days before sleeping on it.

The Nectar is an affordable all-foam mattress that offers lots of pressure relief and body contouring. It works well for most side sleepers, because it helps cushion shoulders and hips. It is also a good option for couples, because it isolates motion well. However, the Nectar mattress isn’t supportive enough for most stomach sleepers and heavyweight people. If you tend to sleep hot at night, you may want to look for a mattress with more cooling features. Learn more in our Nectar mattress video review.

Unlike the other mattresses on this list, the Nectar is an all-foam, memory foam mattress that really offers that classic memory foam experience. Lying down, you should feel yourself slowly sink into this king-size bed. The memory foam will conform to your body and make you feel oh-so-comfortable. Also, while it is a memory foam mattress, the Nectar shouldn’t sleep too hot! The mattress features a breathable cover and cooling gel infusions that we found helped with heat dissipation.

What the testers say: “When sleeping on the Nectar, I could feel the memory foam layers conforming to the curves of my body. The Nectar is one of the most comfortable memory foam mattresses on the market and should be a good fit for anyone who needs pressure relief and contouring.” – Marten, Lead Reviewer

Based on a whopping 50,525 reviews on the Nectar website, the Nectar mattress earns an average score of 4.7 out of 5. There are many reviews stating that the bed has helped mitigate aches and pains, particularly in people who are older. That said, there are many comments calling out the poor customer service that Nectar provides, with some users stating that they waited a very long time for their mattresses to be delivered.

Those who like the feeling of a luxurious pillow top will love the DreamCloud Premier.

Stomach sleepers won’t get enough support on this mattress. If you sleep primarily in this position, take a look at our best mattresses for stomach sleepers. If you prefer the feeling of a memory foam mattress, the DreamCloud will be too bouncy for you. You should check out our best memory foam mattresses.

The DreamCloud Premier is a luxurious hybrid that gives you the feeling of sleeping in a nice hotel. Its combination of foam, coils, and cooling materials make it an ideal pick for both back sleepers and hot sleepers as well. At the same time, it is plush enough for the majority of side sleepers. However, if you sleep on your stomach, take a look at the firmer DreamCloud Luxury Hybrid mattress. Learn more in our video review.

A king-size mattress is a big investment. Odds are, you’ll be sleeping on this mattress for years to come, so you’ll certainly want to prioritize comfort. The DreamCloud Premier has you covered in this department, as its plush pillow top provides luxurious cushioning that helps relieve pressure in sensitive areas of your body. The hybrid construction underneath the pillow top provide ample support, so this mattress really has the best of both worlds—the comfort of a soft foam mattress and the support and durability of an innerspring mattress.

What the testers say: “The DreamCloud Premier mattress is a luxury hybrid that has been helping people sleep in style for years. It offers an excellent balance of comfort and support because of its plush pillow top and supportive coils.” – Marten, Lead Reviewer

It has a bouncy, responsive feel. This is great for combination sleepers who benefit from a bed that makes it easy to change positions at night. The WinkBed features zoned support. With firmer foam at the top and bottom and more cushioning foam in the middle, this bed has excellent lumbar support. This bed sleeps cool. Thanks to the breathable coils and gel-infused memory foam, hot sleepers can expect a cool night’s rest.

This isn’t the best option for motion isolation. Instead, check out our list of the best mattresses for couples. The WinkBed doesn’t have a traditional “sink-in” memory foam feel. Instead, check out our list of the best memory foam mattresses.

The WinkBed is a versatile mattress that provides zoned support and cooling comfort for a fair price. This bed’s excellent responsiveness makes it a good fit for combination sleeper that want a bed that’s easy to move around on. For couples looking for motion isolation, though, this probably isn’t the best choice. Instead, check out the Nectar Premier Copper. Learn more in our video review.

The WinkBed — especially the King-size — is a luxurious hybrid mattress with a traditional innerspring feel. Among its many notable features are tall, supportive coils, zoning, and a plush pillow-top. It’s also available in multiple firmnesses, so you can select from a Softer, Luxury Firm, Firm, or Plus model. The Luxury Firm is their most popular and we found it might be a great mattress for combination sleepers — comfortable for back sleepers, side sleepers, stomach sleepers, and anyone who switches between all of these positions.

What the testers say: “When I lay on the WinkBed, I got a pleasant balance of comfort and support, especially when sleeping on my back. The zoning in this mattress provides great lumbar support, though I did feel a bit too much pressure while side sleeping on this mattress. If you’re a lightweight or average-weight sleeper though, you might find a bit more pressure relief than I did. –Marten, Lead Reviewer

The WinkBed earned a 4.8 out of 5, based on 8,414 customer reviews submitted to the WinkBed website. Much praise is given to the firm yet somehow soft feel of the mattress, as well as the ease-of-movement that the construction provides. Not all is well, though, as some customers found it lacking in pressure relief, resulting in hip and back pain.

The Saatva mattress is a great option for combination sleepers. It is available in multiple firmness options, but the Luxury Firm model works well for multiple sleeping positions. The Luxury Firm model of the Saatva will work well for most back sleepers. Its balance of comfort and support and zoned construction ensure you’ll sleep in good neutral alignment. Shoppers looking for a long-lasting mattress will love the Saatva. It feature high-density foam and durable coils that should ensure it lasts for over 10 years.

If you like the feel of a memory foam mattress, you’re not going to love the feel of the Saatva. Instead, you should take a look at our best memory foam mattresses. Lightweight side sleepers might not get the best pressure relief, even on the softest Saatva model. If you weigh less than 130 lb, check out our best mattresses for lightweight people.

The Saatva is a luxurious hybrid innerspring mattress that should be a great long-term investment. It is available in multiple firmness options, so it should work for the majority of sleeping positions, and its Luxury Firm model is one of the best mattresses for back sleepers. However, lightweight side sleepers and fans of memory foam should look elsewhere. Learn more in our video review.

If you’ve visited some of our other best-of lists you may have noticed that the Saatva appears quite often. It’s true: We love this mattress. The two sets of coils, combined with a plush pillow top, deliver that luxury hotel feel that so many people look for. Plus, the Soft, Luxury Firm and Firm options mean that you can select the firmness that best matches your needs. But for the best balance of comfort and support, we recommend the Luxury Firm model.

What the testers say: “The Saatva gives that classic feel that’s expected from a coil mattress with a pillow top. There’s some bounce from the multiple layers of coils, and a soft, plush feel on top. When I lie on the mattress, it feels more like I am sleeping “on” the mattress rather than “in” it.”– Marten, Lead Reviewer

On the Saatva website, the classic Saatva mattress has 2,888 customer reviews with an average score of 4.8 out of 5. Many of these reviews praise the high-quality, comfortable materials used in the Saatva, as well as the excellent customer service. On the flip side, a few customers were disappointed to find their Saatva sagging after just a few years.
