Mattress sheet system

Abstract

An easy-change mattress sheet system having a top panel selectively interconnected to lateral panels covering at least a portion of the four sides of a mattress is provided. The lateral panels may employ an elastic seam comprised of a vertical drop seam bounded by upper and lower 45-degrees seams, wherein the length of the vertical drop seam varies by mattress thickness. The top panel may be secured to the lateral panels with a simple attaching device. The top panel can be completely removed from the lateral panels by unfastening the simple attaching device. Accordingly, removing/replacing the top panel can be easily accomplished without disturbing the mattress.

What is claimed is: 
     
         1 . A sheet system for a mattress, comprising:
 a bottom base sheet adapted to cover at least a portion of a mattress bottom surface;   a lateral sheet adapted to cover at least a portion of lateral surfaces of the mattress, the lateral sheet having corner segments consisting of an upper angled overhanging portion, a vertical portion, and lower angled portion integrated into the bottom base sheet ( 50 ); and   a removable top sheet adapted to cover a top surface of the mattress and selectively attached to the lateral sheet by a zipper having a zipper pull.   
     
     
         2 . The sheet system of  claim 1 , wherein the top sheet includes an overhang configured to conceal at least a portion of the upper angled overhanging portions. 
     
     
         3 . The sheet system of  claim 1 , wherein zipper teeth of the zipper extend at a distal end of the zipper beyond a zipper start point associated with a zipper slider head. 
     
     
         4 . The sheet system of  claim 1 , wherein zipper teeth of the zipper end at a distal end of the zipper before a zipper start point associated with a zipper slider head, and wherein zipper tape associated with the distal end extends past the teeth and is attached to zipper tape associated with a slider head of the zipper. 
     
     
         5 . A sheet system for a mattress, comprising:
 a bottom base sheet and a removable top sheet which are attached by a zipper having a zipper pull, wherein the base sheet covers the bottom and the four sides of the mattress, and the top sheet covers the top surface of the mattress, wherein zipper teeth of the zipper extend at a distal end of the zipper beyond the point of a zipper start point.   
     
     
         6 . The sheet system of  claim 5 , wherein a slide of the zipper is located on the base sheet. 
     
     
         7 . The sheet system of  claim 5 , wherein a distal end of the zipper extends approximately 5 cm longer than the perimeter of the mattress. 
     
     
         8 . The sheet system of  claim 5 , wherein the zipper, after securely attaching the top sheet and the base sheet, is located on the mattress perimeter and is hidden under a flap associated with the top sheet. 
     
     
         9 . The sheet system of  claim 5 , wherein the bottom base sheet comprises elastic. 
     
     
         10 . The sheet system of  claim 5 , wherein the mattress is used in a bed selected from the group consisting of a crib, a toddler bed, or a bunk bed.
