Best Firm Mattresses
Firm mattresses (7–9 on the 1–10 scale) are ideal for stomach sleepers, back sleepers who need extra lumbar support, and heavier sleepers whose weight would compress a softer mattress to an effectively firmer feel. A truly firm mattress keeps the spine flat, prevents hip sinkage, and provides a stable surface that won't compress unevenly over time.
How We Ranked
- ✓Firmness 7–9+ on the 1–10 scale
- ✓Stable, non-compressing support core
- ✓Good or excellent edge support
- ✓Suited for stomach/back sleepers
