Best mattress firmness for your sleep position
The right mattress firmness depends heavily on your dominant sleep position, since it changes where your body needs support.
By position
- Side sleepers: a medium-soft mattress that cushions shoulders and hips.
- Back sleepers: medium-firm, to support the lower back's natural curve.
- Stomach sleepers: firmer, to prevent the hips from sinking and straining the spine.
When to replace
Most mattresses lose adequate support after 7-10 years — sagging or waking with new aches are common signs.
