Squatting stool

Abstract

A squatting stool may feature two opposed support plates with at least one variable width coil springs therebetween. The larger diameter portion of the springs should be located towards the bottom of the stool, thereby positioning the lower spring constant downward and allowing for collapse of the springs from the bottom upward.

What is claimed is: 
     
         1 . A stool to promote a squatting posture, the stool comprising:
 a bottom plate designed to be supported upon a ground surface;   at least one conically shaped coil springs positioned on an upper surface of the bottom plate; and   a top plate designed to support a user, resting upon the at least one conically shaped springs;   wherein said sat least one springs can support the full weight of an adult person in a squatting position.   
     
     
         2 . The stool of  claim 1 , comprising three springs. 
     
     
         3 . The stool of  claim 2 , the three springs each having a variable spring constant. 
     
     
         4 . The stool of  claim 3 , the three springs being conically shaped coil springs with a variable radius with height, and connected to the plates with a narrower radius towards the top plate so as to maintain the stability of the upper plate.
