The Composition chair is designed by Kouichi Okamoto in 2009. This chair is only made with wire, and weighs as much as 50kg. It holds together only by the pattern that keeps the wire tangled in to each other, and no bolts or screws are used. The tolls used are a piece to make the pattern with and a pair of pliers to bend and attache it together.
I wonder if this chair is comfortable to sit in? Visit www.kyouei-ltd.co.jp and see more of his designs!
