Frequently asked questions
- Do memory foam mattresses sleep hot?
- Older foams can trap heat, but many now use open-cell or gel-infused layers and breathable covers to disperse warmth. Side sleepers who sink in deeper tend to feel it most.
- How firm should a memory foam mattress be?
- Side sleepers usually suit medium firmness for shoulder and hip relief, while back and front sleepers often prefer firmer support to keep the spine aligned.
- How long do memory foam mattresses last?
- Quality foam mattresses commonly last several years before support declines. Higher-density foams resist sagging longer, and rotating the mattress regularly helps even out wear.
