A king size mattress can comfortably fit you and your sleep partner with plenty of room for both of you to stretch out. We recommend a king for anyone who needs extra space while they sleep. This size might also be practical if pets or small children share your sleep area from time to time. Split king models cater to people who own adjustable beds.
As a standard size, king mattresses are widely available, and you can choose from many different options. Below is a list of mattresses that our testing team has determined to be the best options for king size. Our team performed thorough research and hands-on tests to ensure that this list includes the best overall mattresses on the market. We considered criteria such as price-point, since king beds cost more money than beds in smaller sizes. We also looked at durability and temperature neutrality, since king size beds are often purchased by couples.
If you're curious to learn more about our picks, read our reviews below. At the bottom, we also provide a buyer's guide to shopping for king size mattresses. Our guide offers practical advice on how to find the right king mattress, which types of sleepers will benefit from these mattresses, and which mattresses are best for a king size.
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.
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.
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.
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.
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.
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.
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.
The support core contains high-density polyfoam that prevents uncomfortable sagging and promotes spinal alignment. We found that this layer reinforces the medium firm (6) feel without making the mattress feel overly stiff or rigid. At 14 inches thick, we consider the Premier Copper a high-profile model.
Thanks to the thick profile and medium firm (6) feel, we recommend the Bear Star Hybrid to anyone seeking a combination of close cushioning and good overall stability. The mattress begins with a plush Euro-top over a three-layer comfort system featuring polyfoam on the top and bottom and memory foam in the middle. This mixed-foam arrangement provided a mix of contouring and responsiveness. We noticed a light bounce when getting onto the mattress, followed by gentle conforming.
In addition to pressure relief, other performance areas where the mattress excelled during our tests include motion isolation, ease of movement, and responsiveness for sex. For the latter two categories, we found the surface sufficiently bouncy and could slide across the surface without feeling trapped. At the same time, our testers didn't detect much motion transfer when lying side by side on the mattress.
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.
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.

A king mattress is a noteworthy investment, and hopefully one that you'll be able to enjoy for many years. To help you find the best king mattress for you, we'll discuss different types of king mattresses, who is best-suited to a king mattress, and factors that influence comfort and support.
Introduced to the mainstream bedding industry in the 1940s, king mattresses are the largest of the standard sizes in terms of surface area. A king mattress measures 76 by 80 inches, leaving more than enough space for two adults to sleep side-by-side. King mattresses are becoming increasingly popular with multiple subsets of sleepers, including single adults, couples, and families.
Single Adults: With its imposing build, a king size mattress can make a powerful statement in a spacious bedroom. If you sleep alone, a king size mattress can be the perfect accent for your carefully curated interior design. For taller sleepers, larger sleepers, or those who frequently switch sleeping positions, a king mattress also allows enough room to sprawl out and get your beauty rest.
Couples: Falling asleep while spooning is romantic, but it's not for everybody. A king size mattress is 16 inches wider than a queen mattress, giving each partner ample room to sleep comfortably. If you and your partner have trouble agreeing on mattress firmness, you can take things one step further and buy a split king with two different feels.Families: There's nothing cuter than having the kids cozy up with you in bed, but if you're short on space, this can make it tricky to get to sleep. A king size mattress is the best option if you and your sleeping partner want some extra room for kids or pets.
There are several variations of the king size mattress. The most widely available alternative is the California king. Measuring 72 by 84 inches, the California king size is 4 inches narrower and 4 inches longer than the standard king.
The extra length of the California king makes it popular with taller individuals. However, many people prefer the aesthetic appeal of the standard king mattress. This size may also be more convenient for heavier sleepers or those who anticipate sharing the bed with children or pets.
Most mattress manufacturers offer king and California king mattresses at identical price-points, although it might be slightly harder to find bedding for the latter. King and California king mattresses may also come in a split version, in which each side can be customized with a different firmness level. As split king mattresses aren't fully attached to each other, they also allow less motion transfer.
Other types of king beds include Alaska king (108 by 108 inches) and Wyoming king (84 by 84 inches). These are rarely found through regular channels and may need to be specially ordered where available.
A king size mattress may be ideal for sleepers who love spreading out in bed, but not everybody has the space for such a hefty mattress. Here are some pros and cons to weigh if you're considering the jump to a king size mattress.
Definition: Innerspring mattresses are built almost entirely of steel coils that provide bounce, support, and airflow. Some innerspring mattresses may have a comfort layer, but this does not significantly change the feel of the mattress.Highlight: Customizable. Innerspring mattresses pair well with mattress toppers. You and your partner can use a split king mattress to give each side a different feel and eliminate the problem of motion transfer that can arise with interconnected coils. 59ce067264
