A wire rod type stacking office furniture chair and method of assembling same, comprising, including a separate chair seat and back for same, a pair of endless rodding members each defining along the left and right sides of a chair a lower quadrilaterally contoured base frame having lower floor engaging runners that may be glide equipped and upper runners above the chair lower runners that support the chair seat between them, with the rodding members adjacent the rear of the chair each defining a similar vertically oriented upright, chair shoulder forming loop, between which shoulders the chair back is supported. The chair back comprises an assembly including a mounting pan fixed between the chair right and left side shoulder forming loops, an inner opaque back member, and an outer opaque back member, with such back members being secured together in opposed relation on either side of the mounting pan and in encapsulating relation to such pan, by interfitting devices that are also concealed. The chair seat also comprises a seat assembly including an opaque mounting seat pan and a bracket plate fixed to each of the rodding member upper runners; the seat pan and bracket plates are arranged to provide interfitting devices similar to those employed in connection with the seat back, for anchoring these chair components to the chair frame.
In a chair that includes a back assembly in the form of a fixedly mounted back pan, an inner imperforate opaque back member, and an outer imperforate opaque back member, with said members being of a similar sizing and being disposed in encapsulating relation on either side of said back pan to define oppositely facing back surfaces, with said inner back member and said back pan respectively including first hooks and corresponding first keyholes for adjustable mounting said inner back member on the inner side of said back pan by limited movement of said inner back member in a first direction relative to said back pan, and said outer back member and said back pan respectively including second hooks and corresponding second keyholes for adjustably mounting said outer back member on the outer side of said back pan by limited movement of said outer back member in a second direction relative to said back pan, the method of attaching said members to said back pan including the steps of:
