Top 10 Best King Bed Mattresses
for October 2022

MOOZ's editors select recommendations independently. Purchases made through our links may earn us commissions.

Buying a mattress is one of the most important decisions you can make. Your mattress should be comfortable and supportive, healthy and hygienic, and it should last you a good while. The most common mattress size is a King, but mattresses come in a variety of different sizes depending on your needs.

What is a mattress? Mattresses are made up of layers of different materials, including memory foam, latex, spring coils, or a combination of both. The mattress core is the most important and crucial part of the mattress. The mattress core is the part of the mattress that absorbs your body weight and distributes it evenly for maximum comfort, support, and value. The mattress core should be made of dense and durable materials such as memory foam or latex.

At MOOZ, we test all mattresses in our in-house lab, using our comprehensive performance tests to evaluate all aspects of a mattress including firmness and bounce, edge support, comfort, durability, and more. Our pros also evaluate each mattress for off-gassing, which is when new mattresses give off an odor that makes them smell a little musty. Here are the best mattresses we've reviewed in 2022:
