Abstract

A high density stacking flex chair is disclosed. A frame has a seat attached thereto, and a back pivotally attached thereto. The back is curved and can tilt backwards, but is limited by the frame which, through the back, has a lesser radius of curvature and is angled downward, thus providing stop action for back rotation.
