Mattress sheet and system incorporating the same

Abstract

A mattress sheet is provided that has a panel of a selected size and configuration to be disposed on a mattress in a close fitted relationship. The panel includes a bottom layer that confronts the mattress when disposed thereon, a top layer that provides an upper surface for the panel, and an intermediate layer interposed between the top and bottom layers. A mattress sheet system is provided including a mattress casing sized to receive a mattress in its interior in a close fitted relationship and a mattress sheet that spans the interior when in a fastened state. Cooperative fasteners disposed respectively on the mattress casing and the mattress sheet are located to fasten to one another so that the mattress sheet can be releasably fastened to the mattress casing.

 (1) a bottom panel; and  
 (2) a surrounding sidewall joined to said bottom panel around a periphery thereof to form a casing interior and extending upwardly from said bottom panel to terminate in a top edge portion, said sidewall having an inner surface and an outer surface;  
   (B) a mattress sheet that spans the casing interior when in a fastened state; and    (C) cooperative fasteners disposed respectively on said mattress casing and said mattress sheet and located to fasten to one another so that said mattress sheet is releasably fastened to said mattress casing.    
     
     
         11 . A mattress sheet system according to  claim 10  wherein said mattress casing includes a top panel spaced apart from said bottom panel and spanning the casing interior.  
     
     
         12 . A mattress sheet system according to  claim 11  wherein said top panel is joined to said sidewall around a majority of a periphery thereof so as to form an entryway to allow access to the casing interior whereby the mattress may be inserted through the entryway and into the casing interior.  
     
     
         13 . A mattress sheet system according to  claim 10  wherein said casing is sized to receive the mattress in a close-fitted relationship.  
     
     
         14 . A mattress sheet system according to  claim 10  wherein said mattress sheet includes 
 (A) a bottom layer that faces the casing interior when in the fastened state;    (B) a top layer that provides an upper surface for said sheet; and    (C) an intermediate layer interposed between said top layer and said bottom layer.    
     
     
         15 . A mattress sheet system according to  claim 14  wherein said bottom layer is formed of a water resistant material.  
     
     
         16 . A mattress sheet system according to  claim 14  wherein said top layer is formed of a polyester material.  
     
     
         17 . A mattress sheet system according to  claim 14  wherein said intermediate layer is formed of a water absorbent material.  
     
     
         18 . A mattress sheet system according to  claim 10  wherein said mattress sheet is taut when in the fastened state.  
     
     
         19 . A mattress sheet system according to  claim 10  where said mattress sheet is completely removable from said mattress casing.  
     
     
         20 . A mattress sheet system according to  claim 10  wherein said cooperating fasteners are selected from a group consisting of hook-and-loop fasteners, snaps, button-and-hole fasteners and zippers.  
     
     
         21 . A mattress sheet system according to  claim 10  wherein said cooperative fasteners include 
 (A) casing zipper teeth disposed on the inner surface of said casing sidewall at a location proximate to the top edge thereof;    (B) sheet zipper teeth disposed on said mattress sheet at a location proximate to a peripheral margin thereof and adapted to mate with said casing zipper teeth; and    (C) a zipper slide disposed on either said casing sidewall or said mattress sheet.
