Cushioning device for use in a water container

Abstract

A Cushioning device for use in a water container has an enclosable envelope including a zipper member for opening and closing a portion of the envelope. Padding material is attached to the inner surface of the envelope; and a plurality of pebble members placed within the envelope, such that the cushioning device is adapted to be placed within and sink to the bottom of a water container, and is adapted to be used as a cushion for a person to sit thereupon.

1 . A cushioning device comprising an enclosable envelope including a zipper member for opening and closing a portion of said envelope; padding material attached to the inner surface of said envelope; and a plurality of pebble members placed within said envelope, such that said cushioning device is adapted to be placed within and sink to the bottom of a water container, and is adapted to be used as a cushion for a person to sit thereupon. 
   
   
       2 . The cushioning device of  claim 1 , wherein said envelope is formed from a material that is water resilient, mold resistant, and will not rot. 
   
   
       3 . The cushioning device of  claim 2 , wherein said envelope is formed from a material that is porous, and thereby adapted to allow air to pass therethrough such that the cushioning device is capable of sinking to the bottom of a water container. 
   
   
       4 . The cushioning device of  claim 1 , wherein said padding material is formed from a material that is water resilient, mold resistant, and will not rot. 
   
   
       5 . The cushioning device of  claim 4 , wherein said padding material is attached to the entire inner surface area of said envelope. 
   
   
       6 . The cushioning device of  claim 5 , wherein said padding material is formed from a material that is porous, and thereby adapted to allow air to pass therethrough such that the cushioning device is capable of sinking to the bottom of a water container. 
   
   
       7 . The cushioning device of  claim 1 , wherein said pebble members are formed from a material chosen from a list including ceramic, plastic, polyvinyl, cement, steel, aluminum, and wood. 
   
   
       8 . The cushioning device of  claim 1 , wherein said pebble members are formed from rocks. 
   
   
       9 . The cushioning device of  claim 1 , wherein an amount of said pebble members is chosen to thereby conform with a chosen degree of movement of said pebble members within said envelope, and thereby provide a chosen degree of comfort for a person sitting thereupon. 
   
   
       10 . A combination of a cushioning device and a water container, the combination comprising an enclosable envelope including a zipper member for opening and closing a portion of said envelope; padding material attached to the inner surface of said envelope; a plurality of pebble members placed within said envelope; and a water container including water, such that said cushioning device is placed within and sinks to the bottom of said water container, and is adapted to be used as a cushion for a person to sit thereupon. 
   
   
       11 . The combination of  claim 10 , wherein said envelope is formed from a material that is water resilient, mold resistant, and will not rot; and wherein said envelope is formed from a material that is porous, and thereby adapted to allow air to pass therethrough such that the cushioning device is capable of sinking to the bottom of a water container. 
   
   
       12 . The combination of  claim 10 , wherein said padding material is formed from a material that is water resilient, mold resistant, and will not rot; wherein said padding material is attached to the entire inner surface area of said envelope; and wherein said padding material is formed from a material that is porous, and thereby adapted to allow air to pass therethrough such that the cushioning device is capable of sinking to the bottom of a water container. 
   
   
       13 . The combination of  claim 10 , wherein said pebble members are formed from a material chosen from a list including ceramic, plastic, polyvinyl, cement, steel, aluminum, and wood; and wherein said pebble members are formed from rocks; and wherein an amount of said pebble members is chosen to thereby conform with a chosen degree of movement of said pebble members within said envelope, and thereby provide a chosen degree of comfort for a person sitting thereupon. 
   
   
       14 . The combination of  claim 10 , wherein said water container is formed as a bathtub. 
   
   
       15 . The combination of  claim 10 , wherein said water container is formed as a spa including water jets.
