Abstract

An inflatable mattress topper has a length and width substantially corresponding to the length and width of a mattress so that the inflatable mattress topper can overlie the upper surface of the mattress, substantially within the perimeter of the mattress. The topper has separate left and right inflatable chambers having common upper and lower walls, and each chamber having separate head, foot, left and right side walls. There are a plurality of generally elongate parallel beams between the upper walls and the lower walls of each chamber, each beam extending substantially the width of its respective chamber from a point adjacent the left side of the chamber to a point adjacent the right side of the chamber.

Claims

exact text as granted — not AI-modified

         2 . The inflatable mattress topper according to  claim 1  wherein there is a perimeter chamber extending around the entire perimeter of the topper, encircling the left and right chambers. 
     
     
         3 . The inflatable mattress topper according to  claim 1  further comprising an elongate chamber of substantially the same height as the left and right side walls of the left and right chambers extending from one side of the perimeter chamber to the other side of the perimeter chamber, between the left and right chambers. 
     
     
         4 . The inflatable mattress topper according to  claim 3  wherein the perimeter chamber is in fluid communication with the elongate chamber. 
     
     
         5 . The inflatable mattress topper according to  claim 4  wherein the perimeter chamber and the elongate chamber are in fluid communication with one of the left and right chambers. 
     
     
         6 . An inflatable mattress topper having a length and width substantially corresponding to the length and width of a mattress so that the inflatable mattress topper can overlie the upper surface of the mattress, substantially within the perimeter of the mattress, and comprising separate left and right inflatable chambers having common upper and lower walls, and each of the chambers having a head, foot, left and right side walls, and a plurality of generally elongate parallel beams of substantially the same height as the head, foot, left and right side walls of the chambers, extending between the upper wall and the lower wall, the beams maintaining a substantially constant thickness between the plane of the tops of the chambers and the plane of the bottoms of the chambers. 
     
     
         7 . The inflatable mattress topper according to  claim 6  wherein the beams are substantially parallel, and extend substantially across the chamber from a point adjacent one wall to a point adjacent the opposite wall. 
     
     
         8 . The inflatable mattress topper according to  claim 7  wherein the width of the topper is between 1 and 3 inches narrower than the width of the bed on which the topper is designed to be used, and wherein the length of the topper is between 1 and 3 inches shorter than the length of the bed on which the topper is designed to be used. 
     
     
         9 . The inflatable mattress topper according to  claim 6  wherein the width of the topper is between 1 and 3 inches narrower than the width of the bed on which the topper is designed to be used, and wherein the length of the topper is between 1 and 3 inches shorter than the length of the bed on which the topper is designed to be used. 
     
     
         10 . The inflatable mattress topper according to  claim 6  wherein each beam extends between about 75% and about 95% of the distance across its respective chamber. 
     
     
         11 . The inflatable mattress topper according to  claim 6  wherein the height of each of the beams is substantially the same. 
     
     
         12 . The inflatable mattress topper according to  claim 11  wherein the distance between each beam and its adjacent beam is greater than or equal to the height of the beams. 
     
     
         13 . The inflatable mattress topper according to  claim 12  wherein the distance between each beam and its adjacent beam is substantially equal to the height of the beam. 
     
     
         14 . The inflatable mattress topper according to  claim 6  wherein the first and second chambers are spaced apart. 
     
     
         15 . The inflatable mattress topper according to  claim 14  wherein there is a gap between the left and right chambers, and further comprising an elongate foam member disposed in the gap between the left and right chambers. 
     
     
         16 . The inflatable mattress topper according to  claim 14  wherein there is a gap between the left and right chambers, and further comprising an elongate inflatable element disposed in the gap between the left and right chambers. 
     
     
         17 . The inflatable mattress topper according to  claim 16  wherein the perimeter air chamber is in fluid communication with the elongate inflatable element disposed in the gap between the left and right chambers. 
     
     
         18 . The inflatable mattress topper according to  claim 17  wherein the perimeter air chamber is in fluid communication with one of the left and right chambers. 
     
     
         19 . The inflatable mattress topper according to  claim 16  wherein the elongate inflatable element is in fluid communication with one of the left and right chambers.
