Abstract
A versatile chair having a back assembly, a seat assembly and a leg assembly. Two brackets are formed on the leg assembly and create an axis of rotation for the back assembly and for the seat assembly independent of the back assembly. The back assembly rotates due to a user's weight. The seat assembly is rotated manually. The chair is stackable and nestable with identically structured chairs. A tension system is aligned on an oblique axis to bias the back assembly to an upright position. The tension system is mounted within front legs of the leg assembly.
