We aim to give you the right amount of support to make sure your spine is aligned in order to reduce pain and improve comfort. It’s possible to have too little support, but also too much support. Some of our mattresses are listed as “Side Sleeper Support”. These mattresses are best for people who sleep on their side, or people who toss and turn all night long. Our other mattresses are listed as “All Positions Support.” These mattresses are best for people who sleep on their back or stomach, and side sleepers who are heavier and need a little extra support. Both types of mattresses are designed to be as supportive and comfy as you need!
