Furniture Design Etabu Stackable stool by Alfredo Carreño Etabu is a set of 3 stools that create the feeling of not being in balance when they are stacked. The stools evoke the simplicity and practicality of accommodation with engineering calculations to maintain the balance. The materials used such as plastic and wood, create the perfect combination to avoid friction that may harm the stools. Etabu was designed for reduced spaces maintaining a simple manufacture and an accessible cost to the client. Etabu pretends to use surprise as one of the ways to open people´s minds, increasing unconsciously their creativity.
