This is what sleep feels like when nothing is left to chance. The iZone® 16" Prestige adjusts independently on each side across three dedicated comfort zones, with lumbar firmness adjustable from 1 to 100 through the hand control or mobile app, personalized down to the last degree. Patented flippable foam comfort cubes at the head and foot of each side let you choose between plush and firm, while 3.5" of 7-Zone Cooling MicroTec Gel™ Memory Foam and an additional 1" Gellux® cooling layer deliver deep, pressure-relieving comfort that keeps you cool from the first moment to the last. The copper-infused Ice Lux™ cover works through the night so you never have to. A precision air lumbar chamber gently contours and supports your lower back, so you wake up feeling like yourself again. Wake up without the ache. Without the compromise. Without ever having to choose between a good night's sleep and the person you share it with. Two people, two perfect nights, the way it was always supposed to feel.
