Knee Pillow

Abstract

A knee pillow includes a compressible cushion including a rectangular prism shape, the cushion including a first side and a second side. The knee pillow includes a first concave depression on the first side of the compressible cushion, the first depression extending an entire length of the first side in a first direction and a second concave depression on the first side of the compressible cushion, the second depression extending an entire width of the first side in a second direction orthogonal to the first direction. The knee pillow includes a third concave depression on the second side of the compressible cushion, the third depression extending an entire length of the second side in the first direction. The knee pillow also includes a fourth concave depression on the second side of the compressible cushion, the fourth depression extending an entire width of the second side in the second direction.

What is claimed is: 
     
         1 . A knee pillow comprising:
 a compressible cushion comprising a first side and a second side;   a first depression on the first side of the compressible cushion, the first depression extending in a first direction;   a second depression on the first side of the compressible cushion, the second depression extending in a second direction;   a third depression on the second side of the compressible cushion, the third depression extending in the third direction;   a fourth depression on the second side of the compressible cushion, the fourth depression extending in the fourth direction, wherein the first direction is orthogonal to the second direction.   
     
     
         2 . The knee pillow of  claim 1 , wherein the first direction is orthogonal to the second direction and wherein the third direction is orthogonal to the fourth direction. 
     
     
         3 . The knee pillow of  claim 2 , wherein the first, second, third, and fourth depressions are concave depressions. 
     
     
         4 . The knee pillow of  claim 3 , wherein the first depression extends an entire length of the first side. 
     
     
         5 . The knee pillow of  claim 4 , wherein the second depression extends an entire width of the first side. 
     
     
         6 . The knee pillow of  claim 5 , wherein the first depression and the second depression intersect. 
     
     
         7 . The knee pillow of  claim 6 , wherein the third depression extends an entire length of the second side. 
     
     
         8 . The knee pillow of  claim 7 , wherein the fourth depression extends an entire width of the second side. 
     
     
         9 . The knee pillow of  claim 8 , wherein the third depression and the fourth depression intersect. 
     
     
         10 . The knee pillow of  claim 9 , wherein the first depression is centered on the first side of the compressible cushion. 
     
     
         11 . The knee pillow of  claim 10 , wherein the second depression is centered on the first side of the compressible cushion. 
     
     
         12 . The knee pillow of  claim 1 , wherein the second depression is deeper than the first depression. 
     
     
         13 . The knee pillow of  claim 1  wherein the first depression is deeper than the second depression. 
     
     
         14 . The knee pillow of  claim 1 , wherein the third depression on the second side of the cushion mirrors the first depression on the first side of the cushion. 
     
     
         15 . A knee pillow, comprising:
 a compressible cushion comprising a rectangular prism shape, the cushion comprising a first side and a second side;   a first concave depression on the first side of the compressible cushion, the first depression extending an entire length of the first side in a first direction;   a second concave depression on the first side of the compressible cushion, the second depression extending an entire width of the first side in a second direction orthogonal to the first direction;   a third concave depression on the second side of the compressible cushion, the third depression extending an entire length of the second side in the first direction;   a fourth concave depression on the second side of the compressible cushion, the fourth depression extending an entire width of the second side in the second direction.   
     
     
         16 . The knee pillow of  claim 15 , wherein the first depression and the second depression bisect each other. 
     
     
         17 . The knee pillow of  claim 16 , wherein the third depression and the fourth depression bisect each other. 
     
     
         18 . The knee pillow of  claim 15 , wherein the second depression is deeper than the first depression. 
     
     
         19 . The knee pillow of  claim 15 , wherein the first depression is deeper than the first depression. 
     
     
         20 . The knee pillow of  claim 15 , wherein the third depression on the second side of the cushion mirrors the first depression on the first side of the cushion.
