Abstract: A dynamic posture chair is disclosed which is capable of use in a range of sit/stand positions. The chair includes a mobile base that is selectively movable by the user and the chair member that is mounted to the base with a tilt mechanism that enables the chair member to be selectively and infinitely tilted over a predetermined of tilt positions while resistively restraining the chair member in the selected tilt position. The chair member includes seat and back members that relatively subtend an angle in the range of about 120 degrees to 135 degrees. The chair member has a uniquely shaped fixed seat/back contour that instantly supports in comfort the back, buttocks and thighs of the user in its lowest and highest vertical positions, and in all positions in between.

Abstract: A back support for use with a collapsible body support. The back support includes at least one first rib having a first end, a second end, and a central portion between the first end and the second end, wherein the first end includes structure for pivotally securing the at least one first rib to a first support member. The back support further includes at least one second rib having a first end, a second end, and a central portion between the first end and the second end, wherein the first end includes structure for pivotally securing the at least one second rib to a second support member. The central portion of the at least one first rib is pivotally connected to the central portion of the at least one second rib to form a support surface upon which an individual can rest their back.

Abstract: A motivational device has a vertical support for supporting medallions indicating steps or levels of achieving a goal to permit visual identification of accomplishments leading toward a goal, and when such goal is reached. The device is supported on a base and combined with a supported sculptural work of art. The achievement indicating medallions can be inserted from the exterior of the work of art, and include medallions that are opaque and medallions that are light transmitting and of different colors, for indicating achievement of steps toward a goal. A light source is utilized so that as light transmitting medallions are added to replace opaque medallions, light will pass through the medallion and indicate visually the achievements being made toward a specific goal.
