Abstract
Abstract A therapeutic mattress cover includes overlying first and second fabric sheets of rectangular shape. Laterally spaced rows of first stitching interconnect the sheets throughout their width. A hollow rectangular skirt at its top edge overlies the perimeter of the sheets and depends therefrom. A second peripheral stitching connects the top edge of the sheet with the corresponding two ends and one side of the sheets defining with the first stitching a plurality of transverse tubes with the second stitches closing one end of the tubes. A filler pad of a foam plastic resilient material is nested within each tube, and third stitching connects the remaining side of the skirt to the remaining side of the sheets closing the other end of the tube. The method of making a therapeutic mattress cover comprises stacking first, second and third fabric sheets and applying a plurality of laterally spaced rows of first stitching interconnecting the sheets throughout their width. Superimposing a hollow continuous skirt to overlie and surround the perimeter of the sheets and applying second continuous peripheral stitching connecting the top edge of the skirt to corresponding two ends and one side of the sheets defining with the first stitching a first set of transverse tubes along the length of the first and second sheets and a second set of transverse tubes underlying the first set of tubes with the second stitching closing one end of the tubes. Inserting a filler pad of a foam plastic resilient material into each tube and applying third stitching connecting the remaining side of the skirt to the remaining side of the sheets.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
289 words
A therapeutic mattress cover comprising: a first fabric sheet of rectangular shape; a second fabric sheet of rectangular shape underlying the first sheet; a third fabric sheet of rectangular shape underlying said second sheet; said sheets having spaced sides and ends; a plurality of laterally spaced rows of first continuous transverse stitching intermediate the ends of said sheets interconnecting said sheets throughout their width; a hollow rectangular skirt having top and bottom edges, at its top edge overlying and surrounding the peripheral edges of said sheets and depending therefrom; second continuous peripheral stitching connecting the top edge of said skirt with the corresponding two ends and one side of said sheets defining with said first stitching a first set of transverse tubes along the lengths of said first and second sheets extending between their sides, and a second set of transverse tubes along the length of said second and third sheets, extending between their sides and underlying said first set of tubes, respectively; said second stitching closing one end of said tubes; an elongated filler pad of a foam plastic resilient material snugly nested within and along the length of each tube; and third stitching connecting the remaining one side of said skirt at its top edge to the remaining side of said sheets closing off all of said tubes and retaining said filler pads therein; said first and second stitching defining both sets of tubes and closing their one ends; said third stitching closing the open ends of all tubes, wherein said tubes throughout the length of said sheets define a plurality of laterally connected resilient body support sections of varying widths, arranged side-by-side and adapted to support a user's feet and legs, knees, torso, back, and head.
Claim 2
Dependent Claim
289 words
A therapeutic mattress cover comprising: a first fabric sheet of rectangular shape; a second fabric sheet of rectangular shape underlying the first sheet; a third fabric sheet of rectangular shape underlying said second sheet; said sheets having spaced sides and ends; a plurality of laterally spaced rows of first continuous transverse stitching intermediate the ends of said sheets interconnecting said sheets throughout their width; a hollow rectangular skirt having top and bottom edges, at its top edge overlying and surrounding the peripheral edges of said sheets and depending therefrom; second continuous peripheral stitching connecting the top edge of said skirt with the corresponding two ends and one side of said sheets defining with said first stitching a first set of transverse tubes along the lengths of said first and second sheets extending between their sides, and a second set of transverse tubes along the length of said second and third sheets, extending between their sides and underlying said first set of tubes, respectively; said second stitching closing one end of said tubes; an elongated filler pad of a foam plastic resilient material snugly nested within and along the length of each tube; and third stitching connecting the remaining one side of said skirt at its top edge to the remaining side of said sheets closing off all of said tubes and retaining said filler pads therein; said first and second stitching defining both sets of tubes and closing their one ends; said third stitching closing the open ends of all tubes, wherein said tubes throughout the length of said sheets define a plurality of laterally connected resilient body support sections of varying widths, arranged side-by-side and adapted to support a user's feet and legs, knees, torso, back, and head.
Claim 3
Dependent Claim
54 words
In the therapeutic mattress cover of claim 1, further comprising said widths being approximately 17" for the user's feet and legs, 11' for the knees, 20" for the torso, 15" for the back, and 11" for the head, plus or minus 3" depending upon the size of the mattress cover for a corresponding mattress.
Claim 4
Dependent Claim
16 words
In the therapeutic mattress cover of claim 1, said foam plastic material being a polyester foam.
Claim 5
Independent Claim
241 words
The method of making a therapeutic mattress cover comprised of a plurality of tubes defining a plurality of laterally connected resilient body support sections of varying widths, arranged side by side and adapted to support a user's feet and legs, knees, torso, back, and head, comprising the steps of: stacking first, second and third fabric sheets of rectangular shape of the same area; applying a plurality of laterally spaced rows of first stitching intermediate the ends of said sheets interconnecting said sheets throughout their width; superimposing a hollow continuous skirt having top and bottom edges with its top edge overlying and surrounding the perimeter of said sheets and depending therefrom; applying second continuous peripheral stitching connecting the top edge of said skirt with the corresponding two ends and one side of said sheets defining with said first stitching a first set of transverse tubes along the length of said first and second sheets extending between their sides, and a second set of transverse tubes along the length of said second and third sheets underlying said first set of tubes, respectively, said second stitching closing one end of said tubes; inserting a filler pad of a foam plastic resilient material successively into and along the length of each tube; and applying third stitching connecting the remaining one side of said skirt at its top edge to the remaining side of said sheets, closing off said tubes and retaining the filler pads therein.
Claim 6
Independent Claim
241 words
The method of making a therapeutic mattress cover comprised of a plurality of tubes defining a plurality of laterally connected resilient body support sections of varying widths, arranged side by side and adapted to support a user's feet and legs, knees, torso, back, and head, comprising the steps of: stacking first, second and third fabric sheets of rectangular shape of the same area; applying a plurality of laterally spaced rows of first stitching intermediate the ends of said sheets interconnecting said sheets throughout their width; superimposing a hollow continuous skirt having top and bottom edges with its top edge overlying and surrounding the perimeter of said sheets and depending therefrom; applying second continuous peripheral stitching connecting the top edge of said skirt with the corresponding two ends and one side of said sheets defining with said first stitching a first set of transverse tubes along the length of said first and second sheets extending between their sides, and a second set of transverse tubes along the length of said second and third sheets underlying said first set of tubes, respectively, said second stitching closing one end of said tubes; inserting a filler pad of a foam plastic resilient material successively into and along the length of each tube; and applying third stitching connecting the remaining one side of said skirt at its top edge to the remaining side of said sheets, closing off said tubes and retaining the filler pads therein.
