Whether at school or at an overcrowded family get-together; we've all done time sitting on a cheap, uncomfortable wooden chair. But it doesn't have to be that way. With just a little flexible polymer added to the mix a wooden chair doesn't need a cushion to be comfy.
J.C. Karich's Rombo Chair is proof of that. The backrest and seat are composed of ash plywood segments connected in a diamond pattern using flexible polymer in between. The results are a chair that's still made of cheap components, but one that flexes under your weight providing an enjoyable spot to sit for a spell.
