Meltdown PP Tube 1 chair is designed and created by a British Designer Tom Price. The chair is made from polypropylene tubes by heating and pressing a seat-shaped former into a stack of common plumbing tubes. The ends of the tubes melt and fuse together as they come into contact with the heat, leaving a pattern of irregular holes on the surface of the molded seat. It's an ideal chair made from recycled pipes.
