Back pain rhomboid. Type of mattress!

A very hard/flat mattress can sometimes worsen back pain, but there is no single “best” mattress for everyone. In general, a medium-firm mattress that supports the natural curve of your spine is usually more comfortable than an extremely hard or very soft mattress. Choose a mattress that: Feels supportive without creating pressure points. Does not sag in the middle. Allows your spine to stay in a neutral position. Is comfortable for your usual sleeping position. If you sleep on your back, placing a pillow under your knees may help. If you sleep on your side, keep a pillow between your knees. If back pain persists for more than a few weeks, is severe, or is associated with leg weakness/numbness, bowel or bladder symptoms, fever, or significant injury, please get evaluated by a doctor.

Use soft mattress
