ABSTRACT OF THE DISCLOSURE A chair comprises a pair of laterally spaced-apart seat supports, each of which is of substantially uniform external cross section along its length; the axis of each external cross section is upwardly concavely arcuate, and the two axes define spaced-apart vertical planes. The seat has a pair of laterally spaced-apart sleeves, each of which receives a corresponding one of the seat supports. Each sleeve is of substantially uniform internal cross section along its length, the axis of the internal cross section being coincident with the axis of the respective seat support such that the seat is slidable backward and forward on the seat support and has an increased rake, the further forward it is on the scat supports, by reason of the curvatures of the axes. The back of the chair is mounted by means of articulating resilient connectors on back supports, the back supports, preferably, being integral with the seat supports. The chairs are stackable, and they may be ganged such as by -1- way of interlocking arms for interconnecting them when ganged. An extensible, flexible tubing is received on each of the integral back and seat support frame members and is connected at one end to the back and at the other end to the seat, such that it flexes and extends and contracts as the seat is moved forward and backward and as the back is tilted to different positions.
