Abstract
An ergonomic chair of simplified design includes a seat support member, a backrest support member, and a base member to which the seat support member and the backrest support member are both attached. The base member engages the seat support member in a manner that permits movement of the seat support member between a forward seated position and a rearward seated position. The base member also engages the backrest support member in a manner that permits movement of the backrest support member independent of the movement of the seat support member in a first direction toward the base member and in a second direction away from the base member. The base member also serves to tilt the base member forwardly and rearwardly about a horizontal axis.
