ABSTRACT:
A chair seat structure is formed of a plurality of identically dimensioned planar members and a plurality of plastic connective members having slots to receive and engage the planar members. This construction provides easy handling, economical shipment and storage, and dimensional adjustability of the chair seats during manufacture. In use the chair seats can adjust to uneven floor surfaces which support the frame on which the chair seat is mounted. This adjustability under the weight of an occupant aids in preventing the chair from undergoing discomforting teetering.
