Cooling Technology Side Sleeper Cal King

This hybrid mattress pairs a plush pillow-top layer with supportive pocket coils to draw heat away and encourage airflow throughout your space. The memory foam layer cradles your body to relieve pressure points, while targeted lumbar support keeps your spine in proper alignment. Low motion transfer means movement on one side won't wake a sleeping partner, making shared routines easier. Reinforced edge support prevents sagging near the sides for stability across the entire surface. It also arrives compressed in a box for straightforward setup.

Designed for hot sleepers and couples who can't agree on a thermostat setting, the SweetNight CoolNest® Pro Memory Foam Mattress pairs an advanced four-stage cooling system with a contoured 7-zone support layer to keep you cooler from the moment you lie down through the early-morning hours. More than half of U.S. adults say they sleep hot, and overheating is one of the top reasons Americans wake up during the night. This upgraded model from SweetNight's best-selling CoolNest® series is engineered to address that—managing temperature across four stages of the night so you can sleep deeper and wake up refreshed

This mattress is medium firm. More on the firm side, great for a 9 month pregnant side sleeper. I feel great waking up. Depending on your frame height because of how thick this mattress is you might need a stool to get up. Very nice cooling mattress feature, keeps my hot body husband cooler.. Mamamc. Western Kansas.
