While a firm mattress excels at providing support, those seeking pressure relief may find it worsens joint and muscle pain. If you have arthritis, scoliosis, or chronic lower back pain, a firm mattress without some cushioning and contouring may reduce your sleep quality. Additionally, side sleepers and lighter-weight sleepers may find they require more pressure relief than a firm mattress offers.
Fortunately, modifying a too-firm mattress is easier than a too-soft mattress. Mattress toppers and support pillows can offer the extra contouring you need without requiring you to buy a brand new mattress.
