Designers call the mini vintage Harry Bertoia chair a "classic revitalization," but I'm not certain your average mom would agree. The chair, $850, is made up of more than 2,500 strands of closed-cell extruded sponge cord hand knotted to the chair form. While the look is incredibly fun, I can't imagine cleaning it is a picnic in the park. Would you buy this for your kid's room?
