ABSTRACT:
The present invention provides a chair with a seat cushion thickened toward the front thereof, and thinned toward the rear, positioned on a support frame having a pair of legs extending down to a pair of curved rails which flair apart from one another toward the rear thereof. These rails extend forward sufficiently that the chair can be tilted forward along the rails on a horizontal surface until the top of the seat cushion slopes downward, and these rails extend rearward sufficiently such that the chair can be tilted rearward therealong until the seat cushion top again slopes downward. The backrest extending from underneath the cushion, and then upward therefrom, carries a cushion which is thickened toward the top thereof and thinned toward the bottom. This cushion is adjustably positionable up or down along the backrest to be available to be positioned against a user's lumbar region depending on the length of the user's back. The backrest may also be adjustable suitable forward and backward to fit the length of the user's legs between the pelvis and the back of the knees.
