The top 1.5" Temperature Responsive Gel Memory Foam Layer maintains the ideal temp zone for optimal sleep, adapts to body contours for relief in pressure-sensitive areas and eliminates discomfort for less tossing and turning.

Side Edge Support allows you to sleep edge-to-edge without the fear of rolling off. Unique to the 4Sleep Mattress, our support system resists over-compression and is designed to gently nudge you back from the edge.
