Premium memory foam conforms and responds to your individual shape, while coils help add extra support for your entire body. This Hybrid mattress was designed to combine the best of both worlds for outstanding comfort and support 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 hassle-free. When your Mattress-in-a-Box arrives, simply place the mattress on your bed, remove the interior plastic packaging, and allow time for the bed to decompress and expand to its comfortable shape.
