A king-size mattress is perfect for couples who like to sleep on the same surface, or who wake up feeling stiff and sore. Our testing team has evaluated king-size mattresses based on a number of performance factors such as mattress construction, materials, and firmness. We look at reviews posted online by customers as well as ratings on sites like GoodBed, SleepLikeTheDead and Consumer Reports to make sure we're evaluating the mattresses based on actual user feedback.

We test mattresses in the MOOZ Reviews Lab. For king-size mattresses, we evaluate sleep surface comfort by measuring firmness and identifying the best mattresses for side sleepers, back sleepers and stomach sleepers. We also evaluate mattress construction, including materials and firmness, as well as overall construction, such as strength, durability and overall value.

by SureGuard Mattress Protectors

King (78 in x 80 in) - Fits 9 to 12 inches deep; Zippered Mattress Encasement - Machine wash and dry. Independently lab tested and GREENGUARD Gold certified.

Our daughter wanted a bed and, after the separation of the bed/crib and the shared room, my wife and I realized we needed a new mattress. We purchased king size, and after many nights, realized we needed something better than our old queen size cover. We have always been concerned with bed bugs, so we wanted a bed that would offer maximum protection; King SureGuard is an excellent choice.

King Size Mattress, JINGWEI 11 Inches Cooling-Gel Memory Foam Mattress Bed in a Box, Certified Foam, Pressure Relief Supportive, Medium Firm, 76 X 80 X 11 inches

JINGWEI King Size Mattress

by JINGWEI

Say Goodbye to Back Pain The 11 INCH Mattress features a 3-Layer Design: (1) 2.5" gel memory foam that fits your body perfectly and absorbs 95% of your body pressure; (2) 2.5" comfortable layer with special formula and design for cushioned feel comfort; (3) 6" high density support foam which gives your body perfect support from head to toe and create medium-firm feel.

The JINGWEI 11 Inches Cooling-Gel Memory Foam Mattress Bed in a Box, Certified Foam, Pressure Relief Supportive, Medium Firm, 76 X 80 X 11 inches is a pretty cool mattress. It's comfortable, cool to sleep on, and well made, but lacks the ventilation and design of the Savvy Rest 3 in 1. Our chief complaint about the mattress is that we felt it lacked the support we needed to fall asleep and stay asleep. On the plus side, it's more reasonably priced than many of its competitors, and it's significantly cheaper than many other memory foam mattresses on the market.

PrimaSleep 12 Inch Multi-Layered I-Gel Infused Memory Foam Mattress | White/Blue | King

PrimaSleep 12 Inch Multi-Layered I-Gel Memory Infused Foam Mattress

by Grantec Co., Ltd

I-gel foam particles in the memory foam keep the mattress cool | Convoluted foam provides better ventilation and disperses body pressure

I wasn't really sure what to expect from this mattress. I sleep on a mattress with memory foam, but it's been 12 years and shows no signs of breaking down. I wanted the more traditional memory foam I had slept on, but I needed something deeper than the ones that came wrapped in plastic. So I ordered this mattress in king size, and it exceeded my expectations. I'm 6'2" tall, and the mattress fits me perfectly. I'm able to sleep on my side and have gaps between the mattress and bed, just where I'd need them. The mattress feels firm, but not overly so. I'm able to toss and turn all night without waking up. I'm able to sleep on my back without tossing and this mattress is very comfortable to sleep on in any position. I sleep with a box spring, but with this mattress, I don't have to box spring it at all. I wish I'd ordered this mattress years ago.

If you're up for a new mattress and you like the feel of luxury, the Zinus memory foam + pocket springs hybrid mattress is hard to beat. It's more expensive than our previous top pick, but it has a 10-year warranty, and its combination of foams and springs makes it a great option for those who require customized comfort and support. Overall, we found the Zinus bed to be the tallest in our tests, and it slept cool, with no hot spots, during our tests. In addition, the foam layers provided plenty of support and pressure relief. Every Zinus mattress comes with a lifetime warranty, though its cover is only warrantied for 10 years.

Linenspa 8 Inch Memory Foam and Innerspring Hybrid Medium-Firm Feel-King Mattress, White

Linenspa 8 Inch Memory Foam Innerspring and Hybrid Medium-Firm Feel-King Mattress

by Linenspa

Available in a medium firm 8 inch profile, a medium 10 inch profile, or a plush 12 inch profile that also features gel infusions and individually encased coils

The Linenspa 8-inch Memory Foam and Innerspring Hybrid Mattress delivers excellent value for a low-cost hybrid mattress. Although it's thinner than the foam and innerspring models in our comparison, it still delivers a soft, luxurious feel. Our testers all said it felt like sleeping on a cloud, and its unique foam layer was better than some of the other models we tested at reducing uncomfortable pressure points. The addition of memory foam to the traditional support of an innerspring mattress makes this mattress a good choice for kids rooms, guest beds, or an affordable low-profile option in a master bedroom. The Linenspa 8-inch Hybrid Mattress is also priced about $100 less than other mattresses in this price range, and the organic cotton-polyester cover adds to the mattress's comfort.

Milliard Memory Foam Mattress - His and Hers Split Firm and Soft Couple Bed - 10 inch (King)

Milliard Memory Foam Mattress

by Milliard

Convenient - The beautifully designed cover is removable and machine washable for easy care.

The Milliard Memory Foam Mattress has a firm side and a plush side (which we called medium-soft). The mattress has a medium-firm feel that is nice andsupportive--not too hard not too soft. Its 10-inch thickness is just right for back, side, and stomach sleepers. We also like the fact that it ships compressed and rolled in a box for ease in moving from one location to another.

Olee Sleep 10 inch Aquarius Memory Foam Mattress - King

Olee Sleep 10 inch Memory Aquarius Foam Mattress

by Grantec Co., Ltd

Smartly shipping - Our patented technology allows Our mattresses to be efficiently compressed, rolled and shipped in a box conveniently to your door

The Olee Sleep Mattress lives up to its promise. It's extremely comfortable right out of the box, and it sleeps cool. Oh, and it smells pretty good, too. The mattress feels a little denser than our previous pick, the Amerisleep AS3, and it's firmer overall. It features Olee's new contouring foam, which distributes pressure evenly. The topper is made of a firmer material. That firmness is tailored to accommodate us side sleepers, but it may feel a little too firm for back or stomach sleepers. The mattress is also on the firmer end of this review's price range. All in all, this mattress is a great value.
