Side sleeper will especially love this mattress… The Wondrous is the most adaptable model in the range, suitable for back, stomach, side sleepers. Memory foam mattresses have excellent movement absorption, so motion on one side will not be felt by the person on the other side. Sweaty sleepers rejoice! The UltraStretch ComfortLoft Cover with MoistureProtect textile knit exclusive to Sealy feels immediately and consistently cool to the touch, this coolness is even perceptible through clothes. The top layer is made up of the curve hugging, pressure point reducing, heat dissipating SealyChill Gel Memory Foam. Beneath this layer lies the SealyCool Gel Foam and Sealy ComfortSense Gel Memory Foam for a supportive, yet conforming feel to ensure a restful night free of tossing and turning. The carefully crafted SealySupport Gel Base Foam layer provides essential back support and absorbs movement so that the early to bed and early to rise person and the night owl can achieve perfect resting harmony.
