I bought this set of 4 chairs yesterday at a local shop. Shorty after seeing them I realized that the legs of each chair interlock into each other to form a bench. I can see where it had a square label at one point, but of course its not there now. The chair is made of bent ply. It has a solid back which turns into the seat and it has two legs. The legs are solid and go from side to side. I have tried searching Jacobsen style but I have had no luck.
