The iComfort® Sleep System offers a variety of options so you can find the level of comfort and support that is perfect for you. Choose from four different models with distinct feels ranging from cushion firm to luxuriously plush. Plus, for a totally customizable bedroom experience, you can choose a Serta Motion Perfect® Adjustable Foundation, which allows you to adjust the head or foot of the mattress using a wireless remote. This advanced adjustable foundation also has a massage option with varying levels of intensity, so you can relax your body and mind before you go to sleep. The Motion Perfect Adjustable Foundation features an upholstery-grade cover that matches seamlessly to the mattress for a clean and stylish finish. The exclusive ZipFit™ system uses a durable zipper to attach the adjustable base discreetly to the mattress, using no bulky or unsightly metal bars.
