The chair herein shown as'embodying this invention comprises a frame, a seat portion or member and a back portion or member, both ofwhich are detachably secured to the said frame.

The frame comprises four'corner upright members or posts a, b, 0 and d, which are, and may be of the same construction and design, and each of which is provided between its ends with sockets 10, 12, substantially at right angles to each other.

The sockets 10, 12, are preferably madev siightly taperino inwardly to receive the tapering ends or four cross bars 13, 14, 15, 16, two of which as 13, 14, are inserted into sockets 10 of the corner members to form the side bars of the frame and the other two 15, 16, are inserted into the sockets 12 to y forni the rear front Cross bars of said frame.

rlhe cross bars 13, 14, 15, and 16, constitute the support for a removable seat member which may and preferably will be composed of 'flexible material, preferably an upper layer of cloth or other fabric and an under layer 21 of leather, the fabric layer 20 at its opposite sides and at its front end being provided with folded under iaps or extensions 22, 23, 24, which are stitched or otherwise lirmly secured to the upper layer 20 to form loops through which the cross bars 13, 14, 16 are passed as represented in Figs. 4, 5 and 6.
