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).

Abstract: A game in which objects are moved from a first location to a second location and then are allowed to move through the action of gravity back to the first location can be constructed so as to utilize this movement back to the first location so as to control the manner in which the objects are moved from the first to the second location. This is accomplished through the use of a lever located so as to be engaged by objects passing from the second to the first location. When a sufficient number of objects are located on the lever, the lever tilts so as to discharge the objects so that they can move back to the first location. Such tilting of the lever permits rotation of a wheel; in turn such rotation is used to establish open and closed paths determining the number of ways that objects can be moved from the first to the second location.
