The Wonder Chair by Lee Wen De is a perfect example of a design that takes into account the changing needs of the user to extend its usability. All you have to do is flip it! By setting the orientation in one direction, it can be used as a kid’s chair for eating or a child’s desk for drawing or writing. Flip it over, however, and it becomes a full-size chair for any adolescent or adult. With a simple turn, it can actually grow up with you!
