Mattress Firmness May Ease Chronic Back Pain
Key takeaway
A supportive, often medium-firm mattress may help some people with chronic low back pain sleep more comfortably, but evidence does not prove one commercial system is best for all.
- Very soft surfaces often worsen morning stiffness for people with low back pain.
- Trials more often favor medium-firm support than ultra-soft beds.
