Back Sleeper Guide

Why Back Sleepers Need Medium-Firm

Back sleeping distributes weight evenly, but your lower back (lumbar region) needs proper support to maintain its natural curve. Too soft = sagging and back pain. Too firm = pressure on tailbone and shoulders.

Best Mattress Types

  • Hybrid: Best overall - combines support and comfort (Purple, Saatva)
  • Latex: Excellent support and durability (Avocado Green)
  • Responsive Foam: Good balance without sinking (Tuft & Needle Mint)

Firmness by Weight

  • <130 lbs: Medium (5/10)
  • 130-230 lbs: Medium-firm (6/10)
  • 230+ lbs: Firm (7-8/10)
