King Koil Pocketed coil innerspring futon mattress XVPKN with dandified polyester fiber surrounding cotton and poly foam, this 9 inch plus futon model is supreme. Features individual springs wrapped in a fabric encasement to create Pocket Springs. Mattresses with a more traditional coil system have springs that are wired together. This way each Pocket Spring moves independently, responding to body movement and the contour of the body. Because they're not connected by interconnecting wires, each spring works independently. The weight on one spring does not affect the surrounding springs.
Twin Futon Mattress measures 39"Wide, 75"Long. Comfort: Medium Firm, Warranty: 10 Years, Thicknes: 9 inch.
