Some beds ask you to meet in the middle. The iZone® 12" Essential was built so you never have to. Each side adjusts independently across three dedicated comfort zones, with lumbar firmness adjustable from 1 to 100 through the hand control or mobile app so the support you need is always exactly where you need it. Patented flippable foam comfort cubes at the head and foot of each side let you choose between plush and firm in an instant, while 2.5" of Cooling Convoluted Gellux® Engineered Latex Foam delivers cool, responsive comfort that moves with you through the night. A precision air lumbar chamber gently contours and supports your lower back, so you stop carrying the day into your sleep. 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.
