Firm and supportive mattresses are thought to be the best mattresses for back pain. Memory foam and latex mattresses, for example, adjust to your body, cradling pressure points while supporting and aligning your spine.

The suggested type of mattress for side sleepers is a medium to medium-soft memory foam mattress. During the night, memory foam conforms to the shape of your body, providing proper support for your entire body, particularly your midsection and lower back.

It is important that you do some research about the different types of mattresses for different body types, body weights, and sleeping positions. Firmer mattresses are preferred by heavier persons, but soft foams may sink in too much for comfort and proper support. Lighter sleepers, on the other hand, may sink in less and find firm beds uncomfortable, thus they choose soft to medium firm alternatives.
