Fully upholstered in a 100 cotton cover, the mattress features a deep quilted finish that secures the outer fabric to the top layers. The core of the mattress is made up of small diameter pocket springs, with each coil housed in its own cloth sleeve for total flexibility. This allows each spring to move freely of any surrounding springs, resulting in piston-like support to each part of the sleepers body.
