Concept one

This was my first concept i came up with. I began with simply a stool that had no back rest and evolved it into one that looked like a traditional high backed chair. Through this evolution came this concept. It is in between both- a stool with a sligth backrest. The stool is made from the one piece of xanita board and is quite minimal. I think the design is effective in the way that it folds back onto itself. I am fairly confident that the stool will support the required 150kg.
