This mattress has eliminated the hip and shoulder pain I was experiencing with my old mattresses. I'm a side sleeper. I can't sleep on my back due to medical issues. I even had a 3 inch memory foam topper and thick plush mattress pad on my old mattress and still had hip and shoulder pain that kept me tossing and turning all night. This mattress totally solved the issue without the topper or puffy mattress pad. Highly recommend!
