ABSTRACT:
A dissassemblable chair structure is provided having a conventional lower chair seat section and an upper chair back section. Manually releasable fastening means are provided for detachably assembling the upper chair back section without the use of tools. The lower chair seat section includes legs, a seat portion and, optionally, arm rests, all of which are permanently fastened together. The upper chair back section includes a U-shaped frame member the legs of which are preferably sufficiently flexible to allow them to be moved toward or away from one another slightly during assembly of the upper and lower sections of the chair to compensate for manufacturing tolerance misalignments that may exist between the two sections. A lower cross bar member and resilient straps may be provided on the upper seat back section to increase the strength and comfort of the seat back section.
