The chair has a specially constructed seat made up of a forward section, central section and rear section functioning respectively as thigh, tuber and sacral supports for an occupant seated in the chair. The central section serving as the tuber support is inclined upwardly in a rearward direction at a slight angle. The rear section or sacral support, in turn, is increasingly inclined at a greater angle to terminate in an arcuate rear edge for the seat so that the left and right sides of this rear section wrap around the sides of the central section to provide a crescent-shaped cup rim functioning to support the sacrum even when the occupant sits obliquely in the chair. Back and arm rests are provided and cooperate together to define a hip rest bulge which extends horizontally over 180°so that again proper pelvic support is provided for an occupant sitting obliquely in the chair. The components are so formed that the chair better enables the sitter to freely shift from one sitting posture to most any other sitting posture, all the while providing comfortable support. In essence, the construction motivates the sitter to move about, changing from posture to posture so that the sitter remains more alert and productive than would otherwise be possible.

A physiological chair including a seat having forward, central and rear sections, (a) said forward section sloping downwardly at a first acute angle adjacent to its front edge to its interception with said central section to provide thigh support for an occupant; (b) said central section sloping upwardly at an angle less than said acute angle from its interception with said forward section to its interception with said rear section to provide a tuber support for said occupant; (c) said rear section having a generally crescent shape when viewed in plan so that it wraps partially around the sides of said central section, said rear section initially sloping upwardly at an acute angle corresponding to said first acute angle, thence gradually sloping upwardly more steeply to terminate in an arcuate edge of the seat extending over at least 150°and being in the shape of a cup rim to provide sacral support for an occupant, even should said occupant sit obliquely on said seat; and (d) back and arm rests, said back rest including a lower section concavely contoured when viewed in plan and including a convexly curved portion when viewed in side cross section providing a bulge functioning as a hip rest, each of said arm rests constituting integral continuations of said concavely contoured back portion over arcuate extents so that the tops of the arm rests and concavely contoured back at the same horizontal level define a continuous arc when viewed in plan, said arm rests having downwardly sloping inner surfaces including convex curved portions providing bulges at the same level as and integrally connecting with the bulge on said lower back portion so that the hip rest is extended over a continuous arc and hip and back support is provided by the arm rests when said occupant sits obliquely in said seat.
