The chair is made of a regularly solid material (wood or metal of some sort), while the joints and the skin of the chair are made of rubber. You may bend and turn any way you wish, without breaking or busting. Don’t bend too far, however, as the chair has not been rendered fall-on-your-head-proof. Rubbertastic? The design is said to have been inspired by an old grandpa’s chair that had become loose and creaky. It has character in it’s old age, and as the years have set in, so has the flexibility. This chair is for people who move around a bunch. It’s called “A Restless Chairacter.”
