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. The top portion can be made of an elastic material. 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. ## Claims ### Claim 1 A fitted bed sheet, the fitted bed sheet comprising: a flat top section and a flat seamless four way stretchable elastic bottom section; a seam that joins the top section to the flat seamless four way stretchable elastic bottom section and wherein the bottom section forms stretchable borders at a head and foot of a mattress and flat seamless four way stretchable elastic bottom section together so that the sheet maintains a flat structure as the two sections are flat against each other, wherein the flat seamless four way stretchable elastic bottom section stretches over the sides and a portion of a bottom portion of the mattress, wherein the flat seamless four way stretchable elastic bottom section has a continuous rectangular frame-like shape wherein the frame-like shape allows the flat seamless elastic bottom section to come over the mattress and it substantially ensures the sheet will grip and not slip off the mattress. ### Claim 2 (depends on 1) The fitted bed sheet of claim 1, wherein the flat top section is made of an inelastic material forming a rectangular shaped surface that matches a top sleeping surface of a mattress and extends with additional four way stretchable material at the head and foot and wherein the flat seamless four way stretchable elastic bottom section comprises a rectangular section surface with an omitted center section so that the flat seamless four way stretchable elastic bottom section over slides a portion of the bottom surface of the mattress through the omitted section. ### Claim 3 (depends on 1) The fitted bed sheet of claim 1, wherein the fitted sheet flat seamless four way stretchable 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. ### Claim 4 (depends on 1) 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 additional stretchable material and wherein the flat seamless four way stretchable elastic bottom section comprises a circular section surface with an omitted center section so that the flat seamless four way stretchable elastic bottom section over slides a portion of the bottom surface of the mattress through the omitted section. ### Claim 5 (depends on 1) 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 additional four way stretchable material and wherein the flat seamless four way stretchable elastic bottom section comprises a matching irregular shaped section surface with an omitted center section so that the flat seamless four way stretchable elastic bottom section over slides a portion of the bottom surface of the mattress through the omitted section. ### Claim 6 (depends on 1) The fitted bed sheet of claim 1, wherein the fitted sheet omits additional elastic sewn into the sheet all around the perimeter, corners, or as straps. ### Claim 7 (depends on 1) The fitted bed sheet of claim 1, wherein the fitted sheet omits any additional elastic sewn to perimeters, corners, or cross pieces of the flat seamless four way stretchable elastic bottom section of sheet. ### Claim 8 (depends on 1) The fitted bed sheet of claim 1, the flat seamless four way stretchable elastic bottom section further comprising: an elongated bottom portion allowing more depth for the varying thicknesses of mattresses. ### Claim 9 (depends on 1) The fitted bed sheet of claim 1, the stretchable borders allow for more depth for the varying thicknesses of mattresses. ### Claim 10 A method for fitting a fitted bed sheet over a mattress, the method comprising: a top section and a flat seamless four way stretchable elastic bottom section; sliding the elastic bottom section of a fitted bed sheet over a mattress, wherein a seam that joins the top section to the seamless four way stretchable elastic bottom section and wherein the flat seamless four way stretchable elastic bottom section forms stretchable borders at a head of foot of a mattress and flat seamless four way stretchable elastic bottom section together so that the sheet maintains a flat structure as the two sections are flat against each other, wherein the flat seamless four way stretchable elastic bottom section stretches over the sides and a portion of a bottom surface of the mattress, wherein the bottom section has a continuous rectangular frame-like shape wherein the frame-like shape allows the bottom section to come over the mattress and it substantially ensures the sheet will grip and not slip off the mattress. ### Claim 11 (depends on 10) The method of claim 10, wherein the flat top section is made of an inelastic material forming a rectangular shaped surface that matches a top sleeping surface of a mattress and extends with additional four way 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 flat seamless four way stretchable elastic bottom section over slides a portion of the bottom surface of the mattress through the omitted section. ### Claim 12 (depends on 10) The method of claim 10, wherein the top section is made of an inelastic material and the fitted sheet flat seamless four way stretchable 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. ### Claim 13 (depends on 10) The method of claim 10, wherein the flat top section is a circular shaped surface that matches a top sleeping surface of a mattress and extends with additional stretchable material and wherein the flat seamless four way stretchable elastic 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. ### Claim 14 (depends on 10) The method of claim 10, wherein the flat top section is an irregular shaped surface that matches a top sleeping surface of a mattress and extends with additional stretchable material and wherein the flat seamless four way stretchable elastic bottom section comprises a matching irregular shaped section surface with an omitted center section so that the flat seamless four way stretchable elastic bottom section over slides a portion of the bottom surface of the mattress through the omitted section. ### Claim 15 (depends on 10) The method of claim 10, wherein the fitted sheet omits additional elastic sewn into the sheet all around the perimeter, corners, or as straps. ### Claim 16 (depends on 10) The method of claim 10, wherein the fitted sheet omits any additional elastic sewn to perimeters, corners, or cross pieces of the flat seamless four way stretchable elastic bottom section of the sheet. ### Claim 17 (depends on 10) The method of claim 10, wherein the flat four way stretchable elastic seamless bottom section further comprises: an elongated bottom portion allowing more depth for the varying thicknesses of mattresses. ### Claim 18 (depends on 10) The method of claim 10, wherein the four way stretchable borders allow for more depth for the varying thicknesses of mattresses.
