What are the best mattresses for side sleepers?
The best mattresses for side sleepers are those that fall on the soft to middle of the firmness scale -- medium-soft to medium. You need a mattress that has enough give to alleviate pressure on your shoulders and hips, but not so much that you sink into it. It's important to keep your spine aligned when you're sleeping on your side, since that's what ensures that you'll sleep comfortably and wake up pain-free.
