How to Choose a Mattress for Side Sleepers
Side sleepers need pressure relief at the shoulders and hips. A medium-firm feel often works best, as it supports the spine while cushioning curves. Look for at least 10 inches of thickness to ensure adequate support. Memory foam is a popular choice for its contouring and motion isolation.
What to Look for in a Cooling Mattress
Cooling features vary widely. Gel infusions absorb and disperse heat, but they aren't a cure-all. Breathable covers and open-cell foams also help. If you sleep hot, consider a hybrid with coils for better airflow. Check the foam certifications to ensure low VOC emissions.
