Project modifies the well known form of a piece of furniture so that one movement allows a user to transform it and add new ways of use. The starting point of the design process was the observation of elderly people using a stool in the kitchen. Base form of this piece of furniture is a classic stool. By adding a pop-up element Stool+ gets new features: back rest, support while getting up and in semi-sitting position and small table. The solid ash wood Stool+ is constructed in a way enabling withstanding heavy loads and ensuring durability of use.
