Abstract
Abstract The present invention provides an improved mattress arrangement wherein the outer portion of the mattress body itself includes a deck covering which may be a conventional fabric or sheet of waterproof material for preventing any moisture from passing therethrough and into the interior of the mattress. The removable mattress cover is removably secured to the deck cover about the outer peripheral edges thereof, as by zippers or the like, so that the removable mattress cover can be removed for laundering, washing, cleaning, or replacement. Different and distinct removable mattress covers or pads can be substituted for one another and changed with the season or desires or needs of the individual occupying the bed. Furthermore, the construction of the removal mattress covers may include upper and lower surfaces of natural or synthetic material with intermediate layers of foam materials or fill material and various single layer members or materials, such as sheepskin, or the like, can also be used. Intermediate layers can be disposed between the lower surface of the removable mattress cover and the upper surface of the deck cover, including such members as waterproof sheets and/or absorbent foam pads.
