What a fantastic idea by Charlotte Friis. This chair is made with drawing paper, and as the paper is used , the size of the front cylinder increases following the child’s growth. Clean paper is transferred from the back cylinder to the front simply by rolling the front cylinder backwards. The amount of paper is approx. 500 meters, which means that the paper can be changed twice a week for 5 years. What I love about it the most is that all of the drawings are archived in the same place. Genius.
