A therapeutic chair having a seat, a base configured to rest on a surface, and a seat support mechanism configured to couple the seat to the base and to enable the seat to be rocked in any direction while resisting rocking of the seat. Ideally the seat-support mechanism permits universal motion in all directions about a vertical axis, including 360 degrees of rotation, 40 degrees of side-to-side flexion, and 35 degrees of front-to-back flexion on a universal-type joint. The joint includes a first support member having a projecting post and a second support member having a housing with first and second resilient members mounted therein and configured to slidably receive the post. A unique seat design in combination with the universal seat connector reduces pressure on the legs and facilitates therapeutic exercise when seated.
