Abstract

The present invention is a chair having a first seat portion operably associated with a second seat portion, with the first seat portion disposed in the same plane as the second seat portion when the chair is in a lowered position, and an actuator for moving the first seat portion relative to the second seat portion. When the actuator is actuated, the first seat portion pivots relative to the second seat portion such that the first seat portion is located in a different plane compared to the second seat portion. When in the raised position, the first seat portion is substantially parallel to the ground, which allows the occupant of the chair to easily transfer the occupant's center of gravity to being supported by the occupant's feet and knees.
