ZERO GRAVITY PILLOW The Zero Gravity pillow has the property of slow memory (memory foam pillow), acting as a real shock absorber for a more responsive, more supportive, and smoother bounce back. Each pillow is individually moulded as opposed to cut conforming more effectively to your weight and pressure thermosensitive and responding to the body’s temperature created with an open cell structure that collapses when it is warmed to body heat. It provides pressure relief facilitating blood circulation.
