     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, and particularly to FIG. 1, there is shown a bedding apparatus which broadly includes a bottom fitted sheet member 20, a contoured top sheet member 30 and a contoured blanket member 40. As will be hereinafter described, the top sheet member 30 is configured and dimensioned for being received within the blanket member 40 and suitably attached thereto, with the thus-attached combination, in turn, being configured and dimensioned for attachment to the fitted bottom sheet member 20, which in turn, is fitted to a mattress of corresponding size. 
     The bottom sheet member 20 is a &#34;fitted&#34; sheet, that is, it has a rectangular main portion 21 of approximately the same dimensions as the sleeping surface of the mattress 12 (See FIGS. 2-4) and a peripheral skirt portion 22 attached thereto to form box-like corners. The peripheral skirt portion 22 has a sufficient depth which exceeds the depth of the mattress to allow excess material for forming a peripheral underhang portion 24. 
     Although FIG. 1 does not show the mattress 12, the orientation of the parts of the bottom skirt member are oriented as though affixed to the mattress, that is the peripheral skirt portion 22 depends from the main portion 21 at about a right angle, with the underhang portion encircling a short distance beneath the mattress in the plane of the lower surface of the mattress. For comfort purposes, a pad 26 is sewn to the undersurface of the main portion 21 of the sheet member 20. 
     Referring also to FIG. 3, for affixation to the mattress 12, the terminal end of the underhang 24 is provided with an open hem portion 27, through which is threaded a pair of elastic members 28, each being of a length sufficient to encompass one-half the perimeter of the underhang 24. The free ends 28a of the elastic members 28 are passed through slide lock members 29 to form a drawstring at diagonally opposite corners for enabling adjustment of the tension of the elastic members 28. With the sheet member 20 fitted to the mattress 12, this arrangement provides full encirclement of the underside of the mattress by both the underhang and the elastic members 28, thus providing a sturdy fitting bottom sheet member 20. 
     For reference purposes, and with reference to the orientation of the parts as shown in FIG. 1, the right ends of the parts will be referred to as the &#34;head&#34; ends, and the left ends will be referred to as the &#34;foot&#34; ends. For attachment purposes, the lower edge of the skirt portion 22 of sheet 20, at the junction with the underhang 24, is provided with two first sections 50a, 51a of a separable &#34;zipper&#34; or slide fastener 50, 51. The other mating sections 50b, 51b are attached to the blanket member 40 as will hereinafter be described. 
     The slide fastener sections 50a, 51a, commence at about the center of the foot portion of the bottom sheet member 20, extending around the corners and up the sides a distance about twelve inches form the corners of the head end of the bottom sheet member 20; this distance being sufficient for exposure of the head of the person utilizing the bedding apparatus. For enabling attachment of the other halves or sections 50b, 51b, of the slide fasteners 50, 51, the attachment points of the sections 50a, 50b on the bottom sheet member 20 are separated by a short distance of about one inch. 
     The top sheet member 30 is a &#34;contoured&#34; sheet member, that is, it is somewhat box-like on three sides with sewn corners 30a, 30b, and is oontoured to overlie the bottom sheet member 20. The length of the main portion 31 of the top sheet member is about the same as, or a little larger than, the length of the main portion 21 of the bottom sheet member 20. The width, however, is about one and one half times as wide as that of the bottom sheet member 20 for obvious reasons, that is, to allow for the volume of the human body. 
     The top sheet member is provided with a skirt portion 32 about the foot portion 32a and the two side portions 32b and 32c. The lower edge of the skirt portion has affixed, such as by sewing, a suitable fastener section 60a, such as the &#34;hook&#34; or &#34;eye&#34; section of a hook and eye fastener assembly 60. This section 60a starts along one side portion 32c of the skirt portion 32, around the foot portion 32a and up the other side portion 32b, terminating a distance from the corners of the head end by a suitable distance, designated 36. This distance 36 is again, about twelve inches. 
     The blanket portion 40, in shape, size and dimensions, corresponds approximately to the shape, size and dimensions of the top sheet member 30. That is, it is box-like on three sides of the rectangular main portion 41 with sewn corners 40a, 40b; it has a depending skirt portion 42 configured similarly to the three-sided skirt configuration 32 of the top sheet member 30, with the depth of the skirt portions 32 and 42 being about equal and both being about the same depth, or slightly greater than the depth of the skirt portion 22 of the bottom sheet member 20; and the width of the main portion 42 corresponds to a width equal to or slightly greater than the width of the main portion 32 of the top sheet member, which is about one and one-half times the width of the main portion 21 of the bottom sheet member 20. 
     Sewn on the outer lower peripheral edges of the skirt portion 42 are the second halves or sections 51a, 51b of the slide fasteners 50, 51. They are sewn at locations corresponding to the coacting sections 50a, 51a, for engagement therewith with the main portions 21 and 41, in overlying relation. The slide fastener sections 50b, 51b, terminate a distance 46 from the head end of the blanket member 40, with the fastener sliders 56 being spaced a slight distance apart (about one inch) at the center of the foot end of the blanket member 40. 
     Sewn on the inside of the skirt portion 42 opposite the slide fastener is the other section 60b of the hook and eye hook and eye fastener 60. The length and placement of the section 60b corresponds to the length and placement of the section 60a, as well as the length and placement of the combined zipper sections 50b, 51b. 
     Referring now also to FIGS. 2 through 4, FIG. 4 illustrates the manner in which the contoured top sheet member 30 is fitted into the interior of the contoured blanket member 40. This is done by coupling the hook and eye sections 60a and 60b together, with the corners 30a and 30b at the foot end of the top sheet member 30 fitted snugly into the corresponding inside corners 40a, 40b of the blanket member 40. Thereafter, the slide fasteners sliders 56 are utilized to couple the two pairs 50a,  51a, and 50b, 51b of the slide fasteners 50, 51 together to thereby attach the top sheet/blanket combination to the lower sheet member 20. The volume of the space for human occupancy is depicted in FIG. 2, that is a view from the head end of the bed mattress 12 with the parts of the bedding apparatus attached together and fitted to the mattress 12. The top sheet member 30 and blanket member 40 are shown in &#34;stretched fitted&#34; view to provide an indication of the widths thereof relative to the width of the main portion 21 of the bottom sheet member 20. 
     In accordance with the invention, there is provided a bedding apparatus which is easily assembled and will take just minutes to attach to the associated mattress. The combination allows the user to detach the less bulky top and bottom sheet members 30 and 20, respectively, for laundering without the need for laundering the blanket member 40 nearly as often. 
     The bottom fitted sheet member 20 has a pad 26 permanently sewn into the flat main portion 21 of the sheet member 20 for added comfort. It also contains elastic 28 all about the under periphery, rather than at just the corners as on sheets of current design, with the sliders 29 enabling adjustment of the tension by a drawstring effect. The side fasteners 50, 51 are heavy duty and washable, and sewn at the point where the sheet skirt 22 edge folds under the mattress 12. 
     The top sheet member 30, during construction, is cut at the foot end lower corners 30a, 30b so that the sheet, when fitted to the blanket 40 will fold over the mattress 12. The sheet material, in uncut form, is as long as the mattress 12 plus the mattress thickness or depth. The width is approximately 1.5 times the mattress 12 width for comfort. 
     The blanket member 40 can be selected from a variety of materials, depending on cost and warmth desired. Only one blanket is required. If additional warmth is desired, a comforter could be merely laid over the blanket and stuffed in easily. The blanket material would prevent the comforter from sliding off. 
     While there has been shown and described a preferred embodiment, it is to be understood that various other adaptations and modifications may be made within the spirit and scope of the invention.
