Reactex® System - Serta's exclusive Reactex® System consists of three layers of cooling technology. Each cooling layer has more cooling capacity than the previous layer, so heat is pulled away from your body and deeper into the mattress. The result is cool, comfortable sleep all night long.
The iComfort Hybrid mattress features EverFeel® Triple Effects™ Gel Memory Foam. The iComfort Hybrid also features advanced Duet® Coil System to create a sleep experience unlike no other.
