Sleep is when your body does the majority of its healing and repair, and the surface you sleep on matters more than most people realize. A poor mattress can undermine spinal health, worsen pain conditions, and degrade sleep quality night after night. Here's what to actually look for when evaluating a mattress.
Support vs. Comfort: Understanding the Difference
Support and comfort are related but distinct qualities. Support refers to the mattress's ability to maintain proper spinal alignment, keeping the natural curves of your spine in their neutral position throughout the night. Comfort refers to the feel and pressure relief at the surface. You need both. A mattress that feels comfortable but allows the hips to sink too deeply is unsupportive, creating spinal distortion that leads to morning stiffness and pain.
Coil Count and Quality
For innerspring mattresses, coil count and construction matter significantly. Higher coil counts generally mean better contouring, but coil gauge (thickness) is equally important. Individually pocketed coils are superior to bonnell or continuous coil systems because they respond independently to different body parts, reducing motion transfer and providing more targeted support.
Foam Density and ILD
Memory foam and latex mattresses are evaluated by density and ILD (Indentation Load Deflection). Higher density foam (4+ lb/cubic foot) is more durable and supportive. ILD measures firmness, lower numbers feel softer. Most back pain patients do best with medium to medium-firm support (ILD of 25-31).
Sleeping Position Considerations
Your ideal mattress firmness depends partly on your primary sleep position. Side sleepers need more cushioning at the shoulders and hips to allow the spine to stay aligned. Back sleepers need firm support under the lumbar spine. Stomach sleeping is generally discouraged from a spinal health perspective.
