At 76 inches wide by 80 inches long, a king-size mattress can be a sensible choice for anyone who needs more space than what’s offered by a full, twin, or queen bed. Maybe you have a partner or pet, a tendency to sleep sprawled out like a snow angel, or simply a spacious bedroom that looks too empty with a smaller mattress. No matter the reason, you’ve come to the right place if you’re looking for a comfy and expansive new bed.
When searching for any mattress, not just a king-sized one, it’s important to find a bed that provides soothing pressure relief while still being supportive enough to prop the spine into proper alignment. According to Sleepopolis Chief Medical Advisor Dr. Raj Dasgupta, to find a bed with the ideal balance of these two qualities, you’ll want to look for something that combines “medium firmness, contouring materials like memory foam or latex, zoned support, responsive materials, pocketed coils, layered construction, strong edge support, and proper alignment for the spine.”
With all that in mind, I’ve put together a list of the best king-size mattresses for a variety of body types, budgets, and sleeping positions. To make these recommendations, not only do I put each bed through an extensive battery of tests that measure performance factors such as cooling, motion isolation, and pressure relief — I also vet every product’s trial period, shipping policy, and warranty. My list includes a variety of king beds that range from $1,349 to $2,783 (for an average of $2,137, before discounts), so there should be something here to fit your budget. In 2024, Sleepopolis helped 12,544 people find their perfect bed—I know we can help you find yours, too.
Our Top Pick for King Mattresses
A king mattress is often favored by people over 250 pounds, combination sleepers who tend to switch positions throughout the night, and couples — all of whom benefit from strong edge support. The Nectar gives them just that, despite being made of memory foam. The brand’s recent redesign has added more durability and responsiveness to the bed’s structure.

What I Look for in a King Mattress
Support
I know the support of your mattress is important to you, so I was careful to test each of the mattresses thoroughly so you can be sure you’re getting a comfortable king-sized mattress that is still supportive. To gauge a bed’s support, I pay close attention to how I feel while lying on a mattress, including whether or not my spine is properly and comfortably aligned. I also look at the components of the mattress to determine which provides a strong base of support, such as the innerspring coil unit or core layer of dense memory foam.
Edge Support
We’ve found that one of the benefits of a king mattress is that the additional size allows you to fully spread out and use the whole surface of the bed. However, if a mattress has weak edges, you lose some of that valuable space. Your mattress might also deteriorate faster if it has weak edges. Because of this, I personally tested the strength and support of all of the edges on these mattresses to make sure they’ll hold up under your body weight and maintain shape over the long haul.
Trial Period and Warranty
We know that king-sized mattresses can be pricey investments, but if your bed has a generous trial period and/or warranty, you get the assurance of longevity. I know this is important when investing in a big-ticket item like a king-size mattress, so I looked into the trial period and warranty for all of the mattresses in this list to help you find the one best suited to your budget and needs.

Nectar – Best Memory Foam King-Size Mattress
The Nectar Classic is a memory foam mattress that provides solid support for most light to average weight sleepers. The cushioning memory foam allows for plenty of pain relief around the lower lumbar spine. Most back sleepers and side sleepers should enjoy the pressure relief. Plus, a lengthy trial period, lifetime warranty, and affordable price make the Nectar a reassuring choice for many. Watch our video review to learn more.
What our tester says:
“I think the Nectar Classic does a great job of relieving back pain. The pressure map test results show a lot of blue and green on our backs, meaning back sleepers should experience good pressure relief from the Nectar.” – Nichole Mondshein, lead reviewer and staff writer
Expert Opinion
We think that those wanting an all-foam bed that’s supportive enough to help relieve back pain will love the Nectar Classic. Its contouring memory foam helps with pressure relief around the lower lumbar spine. Unlike other all-foam mattresses, the Nectar provides sufficient support so you don’t sink too far in of the material and throw your spine out of alignment. I was also impressed with the Nectar’s edge support, which is an indication you’ll be able to make full use of your king bed’s surface. Nectar offers a generous 365-night trial and lifetime warranty with this mattress.

Helix Midnight Luxe – Best Luxury King-Size Mattress
Helix has a line of six hybrid mattresses, each with a different level of firmness. The Midnight is one of their medium models. It has enough contouring for side sleepers, but should still be supportive enough for back sleepers, as long as they don’t mind a softer bed. Learn more in our video review.
What our tester says:
“I like the Helix Midnight Luxe for back sleepers and side sleepers. The medium-soft to medium-firm feel should give these folks the right balance of comfort and support.” – Nichole Mondshein, lead reviewer and mattress tester
Expert Opinion
Helix is known for its line of customizable, high-quality mattresses, which gives sleepers so many options to find their best match. I’m especially impressed by one of the brand’s most versatile options, the Midnight Luxe, which is the luxurious upgrade of its popular Midnight mattress. This king-size hybrid has a breathable Tencel cover and packs in two additional inches of comfort foam, as well as a plush pillow top layer. I felt lots of cushion and pressure relief when lying down on the Midnight Luxe, but also enough firmness and support to decide it has an overall medium-firm feel. This bed comes with a 100-night trial and a 15-year warranty.
Saatva – Best King-Size Mattress for Back Pain
The Saatva’s coil-on-coil construction provides a classic innerspring feel. It’s a good option for combo sleepers, who will want to feel free to switch positions and avoid feeling “stuck” in the mattress. It comes in three firmness levels, so you should be able to find one that suits your needs. The white glove delivery Saatva provides is an added perk and will save you the headache of getting rid of your old mattress (they take it away for free!). For more information, watch our video review.
What our tester says:
“I think the Saatva is a great option for back sleepers, as the Luxury Firm model provides enough cushioning for their lumbar region, but also lots of support to keep their spine in a neutral alignment.” – Nichole Mondshein, lead reviewer and staff writer
Expert Opinion
We found that the Saatva’s bouncy innerspring construction offers firm support, keeping my spine aligned when I lay down on it. Built with a coil-on-coil construction, this mattress offers a traditional innerspring feel that still feels cushioned and comfortable thanks to a Euro top layer. The durable steel coils in its support layer prevent sagging and provide lots of back support and spinal alignment, which is important for sleepers with back pain. I also love how the Saatva offers three firmness levels (Plush Soft, Firm, and Luxury Firm), so it should work for most body types and sleeping positions. This bed comes with a 365-night trial and a lifetime warranty.

DreamCloud Original – Best Hybrid King-Size Mattress
The DreamCloud Original is a hybrid mattress with a luxurious feel that back sleepers in particular will love. The coil layer keeps the bed breathable and cool while still being supportive. The memory foam top layer helps make the mattress comfortable, and gives it that luxurious and contouring feel without being too soft, ranking as a 7 out of 10 on our firmness scale.
What our tester says:
“The DreamCloud got a 7 from me because it strikes a nice balance between pressure relief and support. There’s some gentle cushioning up top, as well as some firm bounce in the bed’s core. I think this feel could work well for anyone who likes to feel more lifted up by their bed rather than stuck in it..” – Bridget Chapman, former senior product editor
Expert Opinion
The DreamCloud Original mattress is a hybrid bed, meaning that it’s made with layers of foam and a layer of innerspring coils. The coils provide the necessary amount of support through the back and hips to promote a comfortable, neutral position for your spine. Above the coils, the mattress has a cashmere blend cover, a layer of memory foam, a foam transition layer, and a base layer, all of which work together to create a balanced, luxurious sleeping experience. I found the DreamCloud to be a fairly firm, springy mattress that should work best for back and combination sleepers — and an overall value with generous policies that include a 365-night sleep trial and lifetime warranty.

WinkBed – Best King-Size Mattress for Couples
The WinkBed is a luxury hybrid mattress. It has a similarly supportive and sturdy feel to a traditional innerspring mattress, but upgrades like a Euro top and cooling Tencel cover give it a touch of modern luxury. Available in three firmness levels, there is a WinkBed for just about every sleeper. And a responsive and bouncy feel makes it a great pick for combination sleepers. Learn more in our video review.
What our tester says:
“If you like the feel of a traditional innerspring mattress, the WinkBed could work for you. Since this bed offered great pressure relief around my lumbar region, I’d also recommend it to folks who suffer from lower back pain.” – Nichole Mondshein, lead reviewer and staff writer
Expert Opinion
We think this pillow-top hybrid mattress by WinkBeds is a match made in heaven for couples. First, it has strong edge support, so you can use the entire surface without feeling like its sides might crumble beneath you. I also found the WinkBed to be bouncy and supportive when I lay down on it, which is a nice perk for sex because it helps you change positions easily. Another win for couples: The bed’s comfort foams are infused with cooling gels that work to prevent the trapping of body heat. And last, I recommend couples look for a bed with low motion transfer to prevent you from feeling your partner tossing and turning at night, or vice versa.
While testing the WinkBed’s Luxury Firm model, I didn’t see too many movement vibrations on our seismograph, thus indicating overall low motion transfer — and a likely peaceful night of sleep. The WinkBed is also available in Softer, Firmer, and Plus versions, which makes it one of our most versatile options.

Silk & Snow Hybrid – Best Medium-Firm King Size Mattress
As an affordable option with a medium-firm feel, we think that the Silk & Snow Hybrid should appeal to a wide variety of sleepers, including back sleepers, side sleepers, hot sleepers, and budget shoppers. Learn more in our full video review, where we compare the Silk & Snow Hybrid to the original Silk & Snow, which doesn’t have coils.
What our tester says:
“The Silk & Snow Hybrid is a great middle ground firmness for those who don’t want an ultra-firm bed, but also want to feel well-supported.” – Amelia Jerden, senior staff writer
Expert Opinion
Medium-firm beds are some of the most common in the mattress market because of their versatile feel that can accommodate a variety of different sleepers. The Silk & Snow Hybrid is one such mattress — we rated it at a 6.5 out of 10 for firmness, a truly medium-firm feel. This mattress packs both coils and foam into its construction, offering high-quality support and comfort that far outclasses its reasonable price tag. For a king mattress, it’s rare to find a sub-$1,000 price point, so this only sweetens the deal. It also comes with a 100-night sleep trial and a generous 15-year warranty.
