System and Method for A Fitted Elastic Bed Sheet

Abstract

An easily foldable fitted sheet is disclosed, made of a flat top section with a backside of fabric flat against a backside of the flat bottom section joined together at their outlining edges. The flat top section is an inelastic rectangular sheet of fabric sewn all around at the outlining edges to the flat bottom section which is an elastic rectangular frame of fabric with no middle center and only one seam. When the fitted sheet's flat bottom section is stretched over any mattress it forms the side panels giving a tight fit and grips the underside of the mattress with the silicone beading or strip that is adhered to the inside edge of the bottom section. When the sheet is released from the mattress the bottom section's elastic material retains its flat rectangular shape and lies flat for ease of folding and storage.

1 . A fitted bed sheet, the fitted bed sheet comprising:
 an inelastic top section and a flat elastic bottom section;   a seam that joins the inelastic top section to the elastic bottom section and wherein the flat elastic bottom section forms stretchable borders at a head and foot of a mattress and elastic bottom section together so that the sheet maintains a flat structure as the two sections are flat against each other, wherein the bottom section stretches over the sides and a portion of a bottom portion mattress.   
     
     
         2 . The fitted bed sheet of  claim 1 , wherein the flat top section is a rectangular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material at the head and foot and wherein the bottom section comprises a rectangular section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         3 . The fitted bed sheet of  claim 1 , wherein the fitted sheet flat elastic bottom section is able to stretch over the sides of the mattress and wraps the sides of the mattress for a tight fit and clings to the bottom side of the mattress and when removed from the mattress, retracts back to its original flat rectangular shape for ease of folding flat and storing. 
     
     
         4 . The fitted bed sheet of  claim 1 , wherein the frame shape allows the bottom section to come over the mattress and it substantially ensures the sheet will grip and not slip off the mattress. 
     
     
         5 . The fitted bed sheet of  claim 1 , wherein the flat top section is a circular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material and wherein the bottom section comprises a circular section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         6 . The fitted bed sheet of  claim 1 , wherein the flat top section is an irregular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material and wherein the bottom section comprises a matching irregular shaped section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         7 . The fitted bed sheet of  claim 1 , wherein the fitted sheet omits elastic sewn into the sheet all around the perimeter, corners, or as straps. 
     
     
         8 . The fitted bed sheet of  claim 1 , wherein the fitted sheet omits any elastic sewn to perimeters, corners, or cross pieces of bottom of sheet. 
     
     
         9 . The fitted bed sheet of  claim 1 , the bottom section further comprising:
 an elongated bottom portion allowing more depth for the varying thicknesses of mattresses.   
     
     
         10 . The fitted bed sheet of  claim 1 , the stretchable borders and end pieces allow for more depth for the varying thicknesses of mattresses. 
     
     
         11 . A method for fitting a fitted bed sheet over a mattress, the method comprising:
 an inelastic top section and a flat elastic bottom section;   sliding an elastic bottom section of a fitted bed sheet over a mattress, wherein a seam that joins the inelastic top section to the elastic bottom section and wherein the flat elastic bottom section forms stretchable borders at a head of foot of a mattress and elastic bottom section together so that the sheet maintains a flat structure as the two sections are flat against each other, wherein the bottom section stretches over the sides and a portion of a bottom surface of the mattress.   
     
     
         12 . The method of  claim 11 , wherein the flat top section is a rectangular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material at the head and foot and wherein the bottom section comprises a rectangular section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         13 . The method of  claim 11 , wherein the fitted sheet flat elastic bottom section is able to stretch over the sides of the mattress and wraps the sides of the mattress for a tight fit and clings to the bottom side of the mattress and when removed from the mattress, retracts back to its original flat rectangular shape for ease of folding flat and storing. 
     
     
         14 . The method of  claim 11 , wherein the frame shape allows the bottom section to come over the mattress and it substantially ensures the sheet will grip and not slip off the mattress. 
     
     
         15 . The method of  claim 11 , wherein the flat top section is a circular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material and wherein the bottom section comprises a circular section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         16 . The method of  claim 11 , wherein the flat top section is an irregular shaped surface that matches a top sleeping surface of a mattress and extends with stretchable material and wherein the bottom section comprises a matching irregular shaped section surface with an omitted center section so that the bottom section over slides a portion of the bottom surface of the mattress through the omitted section. 
     
     
         17 . The method of  claim 11 , wherein the fitted sheet omits elastic sewn into the sheet all around the perimeter, corners, or as straps. 
     
     
         18 . The method of  claim 11 , wherein the fitted sheet omits any elastic sewn to perimeters, corners, or cross pieces of bottom of sheet. 
     
     
         19 . The method of  claim 11 , wherein the bottom section further comprises an elongated bottom portion allowing more depth for the varying thicknesses of mattresses. 
     
     
         20 . The method of  claim 11 , wherein the stretchable borders and end pieces allow for more depth for the varying thicknesses of mattresses.
