Seemingly still in the design phase, as this paper chair is being used, the size of the toilet-roll increases. Genius!

The Childrens’ Paper Chair by Charlotte Friis Design Studio is made with drawing paper and as the paper is being “drawn upon”, the size of the front cylinder increases. Clean paper is transferred from the back cylinder to the front simply by rolling the front cylinder backwards. The amount of paper is around 500 meters (about 1640 feet), which means that the paper can be changed twice a week for 5 years, getting larger as your child gets larger.

Fun.
