The Serta iComfort Genius uses a combination of CoolAction Dual Effects Gel Memory Foam and Everfeel Technology to help create a supportive, yet contouring, sleep surface, that also dissipates excess heat. The Genius helps manage a sleeper’s body temperature through the phase change material found in the CoolAction Dual Effects Gel Memory Foam layer. Everfeel technology is added to help the mattress maintain a consistent comfort, regardless of the temperature in your room. The ComfortLast Support Core utilizes support to the lower back while minimizing motion transfer between couples. With an Ultimate Edge foam encased perimeter, you can lie edge to edge, with no difference in comfort. It is also adjustable base friendly.
