All the comfort and trusted quality of a Sealy® mattress, now conveniently packaged in a ready-to-ship box. Fall into a cradling memory foam top that “hugs” your body all night long, so you wake up refreshed and ready to take on the day. This 8-inch memory foam mattress combines distinct layers of foams—including a top layer infused with CopperChill™—to provide comfort and support for all sleepers and, of course, convenience. At Sealy, we want to help you live your best life, which is why we made the delivery and setup of this mattress in a box hassle-free. When your Mattress-in-a-Box arrives, simply place the mattress on your bed, remove the packaging, and allow time for the bed to decompress and expand to its comfortable shape.
