Abstract (en)
[origin: US2013113264A1] A chair comprises a seat and a seat back made of non-resilient materials. The seat has a shape that matches the natural contours of an occupant's buttocks, thighs, and upper legs, wherein: The seat's concave backward portion connects to the concave lowest portion of the said seat back, creating a dedicated concave zone that contours the occupant's buttocks closely; the seat's concave backward portion has in its center a small hump that contours tightly an occupant's sacrum and coccyx if his buttocks are fitting inside the dedicated concave zone; the seat's forward portion has a wide W-shape that contours the occupant's upper legs: the two concave zones of the seat's W-shaped forward portion contours the back sides of the occupant's upper legs, the center zone of the seat's W-shaped forward portion is convex and snuggles the occupant's thighs; the left side and right side of the seat's W-shaped forward portion are convex so that they contour the outer sides of the occupant's upper legs; the seat is inclined backwardly. The seat back tilts backward to stay at an angle of 135 degrees to the seat and contours the occupant's back, wherein: The seat back's lowest portion is concave to contour the occupant's buttocks; the middle portion that is convex to contour the lumbar vertebrae; the upper portion that is concave to contour the thoracic vertebrae; the top is a headrest to provide support to the occupant's head; the left and right edges of the seat back are convex so that the occupant's back cannot bend left or right.
