Mattress firmness affects spine alignment and back pain
Mattress firmness directly influences spinal alignment and back pain, with specialized support designs demonstrably reducing low-back pain and improving comfort.
Multiple studies demonstrate the impact of mattress support and firmness on spinal angles, muscle activity, and low-back pain. Specifically, experimental mattresses designed to alter spinal curvature reduce pain while lying down (Paper 1), mattresses alter lumbar alignment compared to rigid surfaces (Paper 4), and medium-firm surfaces improve pain and sleep quality (Paper 5), while review and biomechanical literature highlight the overall relationship between mattress parameters and musculoskeletal health.

Uses MRI to show that sleeping on a mattress versus a rigid surface induces small but statistically significant changes in lumbar spine alignment and angles.

Shows that mattress firmness and support influence muscle activity and comfort, noting that different firmness levels suit individuals based on anthropometric parameters like BMI.
