Introducing an affordable boxed bed solution, the Emma Pressure Relief Memory Foam 6 Inch Twin Mattress features a soft top layer of memory foam over a dense layer of responsive foam, and a quilted polyester fabric cover with stitched padding for an extra layer of comfort. The perfect solution for a guest or kid room, the Emma memory foam twin mattress comes compressed, vacuum-packed, rolled, and sealed in a small portable box that delivers directly to your doorstep. Foam meets fire resistant standards in this mattress-in-a-box, and it fully decompresses in about 2 hours during the summer, and 72 hours during the winter.
