TEMPUR material responds to your temperature, weight and shape, for truly personalized comfort and support. Heavier areas, like your shoulders and hips, sink in further, while lighter areas sink in less. So whether you sleep on your back, side, or stomach (or change positions during the night) the mattress adapts to you. You get the exact support and comfort your body needs. REDUCES TOSSING AND TURNING; Pressure points those spots where the mattress presses against your body trigger discomfort. Your body shifts position and you toss and turn. As it conforms to your body, TEMPUR material minimizes pressure points that keep you awake. You sleep undisturbed, for a more restful, restorative night. HELPS YOU BOTH SLEEP UNDISTURBED; TEMPUR material dramatically reduces motion transfer, so your sleep partner's movement won't disturb you. When two people are sleeping on a Tempur-Pedic mattress, each is supported independently so if one gets up in the middle of the night, the other is likely unaware. You both sleep undisturbed, and get more hours of rejuvenating rest.
