Abstract:

A chair (10) designed for its comfort, ease of operation, and therapeutic effect. The chair (10) includes an envelope (12) having first and second portions (14, 24). The first portion (14) defines a reservoir (16) therein, and the second portion (24) has a pillar-like member (28) received within an interior (26) thereof. The interior (26) of the second portion (24) communicates with the reservoir (16) defined within the first portion (14) of the envelope (12), and the pillar-like member (28) is sufficiently long so that, when it is received within the interior (26) of the second portion (24) of the envelope (12), it will extend into the reservoir (16). The reservoir (16) is filled with a volume of fill (18) which, typically, comprises stryofoam beads (20). The base (30) of the pillar-like member (28) is immersed within the fill (18), and the fill (18) is of a consistency and density so that, unless a threshhold pressure applied to the pillar-like member (28) is imposed, the member (28) will tend to maintain its position relative to the rest of the envelope (12).
