Designing a chair
is the "Hello World!" of design. For my masters course, the first solo module is an exercise in chair design. It's called Superform, and the brief is to design a "Chair plus..." which I'm free to interpret however I wish. I'm two thirds of the way through the project. I've submitted three chair proposals, and I'm about to build one of them.
The world is full of cantilevered steel tube chairs, and I find them quite appealing. I really like bits of "impossible" mechanics, so I thought I'd go one step further and make a singe-point cantilever chair. It's a single bent piece of steel tube (possibly with some cunning tricks in wall thickness, etc.) upholstered in elastic bands. You can see through the upholstery to be sure there's nothing hidden up its sleeve. It's also super durable - the only bits that will wear out (the rubber bands) can be easily replaced by the user.
