Is a firm mattress better for back pain?

For back and stomach sleepers, a firm surface like this one helps by keeping hips from sinking and holding the spine level. This firm orthopedic bed scores 8.9 for spinal support and contours just 1.51 inches, a light cushion over a stable platform. Firmness preference is individual, though, and side sleepers often need more give at the shoulder. The 365-night trial lets you confirm it works for your body before committing.
