A seat includes a support having a first coupling hole and a second coupling hole disposed therein. The seat also includes a seat cradle having a back, a bottom, a first side fixedly connected to the back and the bottom, and a second side fixedly connected to the back and the bottom. The seat cradle has a neutral position in which a top portion of the back is positioned forward of a bottom portion of the back, and a rear portion of the bottom is positioned below a forward position of the bottom. The seat also has a first cradle coupler extending from the first side of the seat cradle, such that the first cradle coupler cannot rotate with respect to the first side. The seat further includes a second cradle coupler extending from the second side of the seat cradle, such that the second cradle coupler cannot rotate with respect to the second side. The first cradle coupler is received in the first coupling hole and the second cradle coupler is received in the second coupling hole.

A rotatable seat cradle including a lumbar supporting back, a thigh supporting front, an intermediate pelvic support bucket located between the back and the front, and an upwardly sloping transition wall that extends continuously and co-extensively between the pelvic support bucket and the thigh supporting front. The seat cradle is pivotally coupled to a stand or to a yoke connected to a chair base. The thigh supporting front of the seat cradle lies above the pelvic support bucket and cantilevers outwardly from the upwardly sloping transition wall. A seated user shifting his weight towards the front of the seat cradle pushes his legs against the thigh supporting front to generate a rotational force thereagainst for causing a corresponding rotation of the seat cradle relative to the stand or the yoke to which the seat cradle is pivotally coupled.
