These chairs made from plushy toys where made by tow Brazilian brothers Fernando and Humberto Campana. There is not really a design for this chair, the chairs were created by attaching a bunch of stuffed plushy toys to a metal base. This kind of chairs would be perfect for a kid that loves little plushy toys, but I don’t know if this chair is to comfortable. Anyway a good way to keep his toy collection organized.
