Abstract
Abstract A pedestal stool is disclosed having a base carrying a stem on which a seat portion is supported. The base includes a sand-filled, bulbous, ground-engaging bag or sack to enable the stool to be tilted at any angle and held at that angle by virtue of the change in shape of the sack in response to the resultant flow of sand which produces a new equilibrium position for the stool.

Claim 1
Independent Claim
83 words
A seat comprising a seat portion, a stem carrying the seat portion, and a base supporting the stem, the base including a support, a ground-engaging flexible bag secured to the support and, together with the support, defining a chamber, and particulate material substantially filling the support and flowable in the bag to change the shape of the bag in response to displacement of the bag produced by a tilting of the stem whereby to hold the seat in equilibrium in its tilted state.
Claim 2
Dependent Claim
83 words
A seat comprising a seat portion, a stem carrying the seat portion, and a base supporting the stem, the base including a support, a ground-engaging flexible bag secured to the support and, together with the support, defining a chamber, and particulate material substantially filling the support and flowable in the bag to change the shape of the bag in response to displacement of the bag produced by a tilting of the stem whereby to hold the seat in equilibrium in its tilted state.
