Illusory is the closest that one could get to describing Five by Anna Bullus. This one is ‘optical’ furniture: designed to create optical illusion whilst being functional. Five is a set of four stools that can be placed in various configurations to create a larger stool. Each one of these stools is designed to function independently as a small seating or side table. Bring these together, however, and you have a much larger fifth stool at hand. Pleasure to behold and fun to play with, Five is an ingenious creation. The designer makes these to order and any interested user can visit her site for more info.
