     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1  of the drawings, basic bottom sheet configurations  10  of the bedding sheet system of the invention can be seen having multiple long respective mattress engagement retainment strap top and bottom sets  11 A and  11 B, and short right and left side sets  12 A and  12 B with an optional bed frame end engagement retainment straps  13 . The engagement strap sets  11  and  12  are selectively secured to one another once engaged under and about the respective corners  14  of the bed&#39;s mattress  15  as seen in  FIG. 5  of the drawings. Engagement strap  13  once engaged about the bed frame corner is secured to itself, as seen in  FIGS. 1 and 4  of the drawings. A variety of different strap fastener engagements can be used, such as snaps F′, integrated buckles B and hook and loop material “Velcro” (VF) shown in  FIGS. 1 ,  2 ,  3 , and  5  of the drawings.  FIG. 2  demonstrates differing attachment fasteners to attach top sections  17  options as described hereinafter. 
     The primary basic bottom sheet  10  provided in this example, but not limited to, a mounting platform for multiple secondary top section configurations  17  with section inserts as illustrated generally in multiple configuration orientation positions. In this form of the invention interchangeable sheet top sections  17  can be attached at different select areas dependent on user preference by multiple fasteners Velcro V, F, multiple straps S and fasteners F through button holes BH in adaptive combinations to affect placement on the bottom sheet so configured. Examples illustrated are a single cross center section  19  attached by straps S and fasteners F in  FIG. 7  of the drawings, or a single side section  20  in  FIG. 8 and 20A  in  FIG. 9 ; attached by fastener F and straps S in  FIG. 8 , and fastener strips F, fasteners F and straps S in  FIG. 9  of the drawings. Alternate configurations such as independent top sections  21 A and  21 B, center sections  22 A and  22 B and a bottom section  23 A are illustrated in  FIG. 10  of the drawings. Different selected sections as center  22 A. bottom  23 A and side  20 B can be added which can be of a variety of different configurations as generally illustrated in  FIG. 11  of the drawings. Additionally, sewn in sections are configured to provide multiple vertical and horizontal sections of different configurations including, but not limited to padding P in  FIG. 5  and waterproof forms in  FIGS. 6 and 12 . 
     An optional independent waterproof sheet  25  can be used independently with fastener straps or removably attached to the hereinbefore described bottom sheet  10 . Attachment is achieved using a reversible fastener format using interlocking hook and loop material V on the engagement straps. It will be evident that the waterproof sheet  25  may be attached to the top of the bottom sheet  10  and although it could be slept upon given the addition of lightweight material  25 A, it was intended to be primarily used under bottom sheets of conventional and more luxurious fabrics. It will be seen as with other optional sheet top sections  17  in a reversible fastener format by use of interlocking hook and loop material strips on perimeter edges, straps and sections that top and bottom surfaces can be utilized. It will be evident from the above description that the adaptive strap fasteners can be used in which secondary attachment criteria can be achieved in overlapping, under extending and adjacent co-planar orientation and not be limited thereby well within the scope of the hereinbefore described fastener attachment configurations. 
     The use of separate waterproof sheets  25 , as noted; provide waterproof material cover with lightweight fabric  25 A adding comfort and preventing slippage if used under a common sheet or this product&#39;s bottom sheet. Such construction would be by both layers sewn and bound around their perimeter edges together. 
     Referring now to  FIGS. 12 ,  13  and  14  of the drawings, an alternate waterproof sheet  25 B can be seen with a fabric lip  26  defining its perimeter edge as an optional attachment or independent attachment to the mattress or the bed frame. The waterproof sheet  25 B allows for a “bottom sheet” to be inserted within the waterproof sheet field without interfering with the operational function of the lip  26 . The sheet  25 B has a variety of forms which illustrate the upstanding edge lip portion  26  that is derived by outer and inner perimeter drawstrings  27  within channels  27 A so as to be “drawn” to gather the lip edge material pulling same forming the upstanding lip  26  as a perimeter water and moisture barrier. Multiple corner configurations can be seen at  28 A so as to be rounded integrally at  30  or alternately as a square corner at  31  which is formed having an attachment fastener tab  31 A. To provide placement retention of selected “bottom sheet”, the waterproof sheet  25 B field may have a plurality of fasteners  32  attached to the top side and/or the lip top and underside. Multiple long top and bottom engagement strap sets  33 A and  33 B and short side engagement straps  34 A and  34 B respectively topsides thereof provide a retainment pattern hereinbefore described in the primary form of the drawing. 
     Top sheets of various configurations, as seen in  FIGS. 15 ,  16 , and  17  attached to bottom sheet  10 , of varying configurations permanently or removably using a variety of fasteners such as, but not limited to hook and loop Velcro, snaps, and magnetic snaps (not shown). 
     It will be evident from the foregoing descriptions that a universal multiple configured bedding sheet system has been illustrated and disclosed that it will be evident to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention.
