Memory foam and latex consistently top the list of mattresses better-suited for overweight people, according to What's the Best Bed?. In addition, shoppers should look for firmer, thicker mattresses and request a trial period during which they may return the mattress if not satisfied.
Because of its high level of support and ability to contour to the sleeper's body, memory foam often makes a good choice for overweight people. Two examples of highly-regarded memory foam mattresses include Serta iComfort and Amerisleep.
Latex mattresses offer another good option, but they need to have a thickness of at least 9 inches and contain 100 percent latex. These mattresses prove quite durable. Two brands considered superior in this category are Astrabeds and Flobeds.
