What to look for in breathable side sleeper mattresses

The best breathable mattress for side sleepers combines airflow with pressure relief and support for comfortable, cooler zzz's.

1. Breathable Materials

Look for breathable foams, innerspring coils or hybrid designs that promote airflow through the mattress. Cooling covers and moisture-wicking fabrics may also help you stay more comfortable throughout the night.

2. Pressure Relief

Side sleepers often need cushioning around the shoulders and hips, where pressure can build. Memory foam or other contouring comfort layers can help distribute your weight and reduce pressure in these areas.

3. Supportive Alignment

A supportive mattress should help keep your head, neck and spine aligned while you sleep on your side. Look for a design that cushions the hips and shoulders without allowing your midsection to sink too deeply.

4. Firmness Level

Many side sleepers prefer a medium-soft to medium mattress that balances cushioning and support. Your body type and personal comfort preferences also matter, so consider trying different firmness levels before you choose.
