We keep seeing chair concept after chair concept but who said that the average furniture-making enthusiast can’t create his or her own original design? Take for example an Instructable user that decided to make his own chair out of birch plywood, cast aluminum and, the piece of résistance, pool noodles. That’s right the pool noodles used to build this do-it-yourself chair will act as the seating area and the back of the chair and, at least from the distance, everything looks quite comfortable. Add to all that a pinch of mathematics madness and you should be in for a great project. In case you do build a similar chair, or come up with your own DIY design then by all means, drop us a shout.
