Frequently Asked Questions
What makes a mattress good for side sleepers?
Mattresses that combine contouring foam and supportive coils or zones are best—they alleviate pressure at the hips and shoulders while ensuring the spine stays straight all night.
Should I choose a soft or medium-firm mattress?
Medium-firm tends to balance cushion and support, preventing sagging or soreness. Extra-soft models may feel comfortable at first but rarely provide enough structure for side sleepers over time.
How important is cooling for side sleepers?
Very important—side sleepers often burrow into the mattress, trapping heat more easily. Cooling gels, ventilated foams, and breathable covers can make a significant difference in sleep quality.
Does a longer trial period really matter?
Absolutely. A 365-night trial lets you fully test the mattress through every season and position, reducing buyer’s remorse and ensuring lasting comfort.
