I have this old cherner-style (but unmarked) bent ply chair that we bought in terrible condition 20 years ago and used as a side chair until one of the legs snapped. We had it repaired (glued) and then it broke again a few years later beyond repair.

I want to put the seat on legs, but searching high and low, I have no idea where to even start.

An Eames H-base (DSX) narrow-mount would still be too wide as the screw holes are 5" apart on center side-to-side and 5 1/1" front-to-back.

the one-piece bent ply seat and back, resting on a pink eames shell chair on an H-base next to our kitchen table to the right and a Hay side table to the left.A bunch of potted plants are on the credenza on the back wall.

the ruins of the base, wood from the veneer still glued in places, screw hardware remains in three, the top right corner is stripped completely.
