PostureTech® 2.0: deep-down support that springs back

A higher-gauge wire and re-engineered head design give a steadier, more stable base. The coil's unique geometry responds to your shape and spreads your weight evenly, so hips and shoulders are supported rather than left to sink. Twice tempered and tested by Sealy scientists.

What's inside, layer by layer
