The Tab Stool by 5.5 Designers

The tab stool by 5.5 designers is lightweight and easy to assemble without nail, key or screw. The design of the stool is based on four identical profiles which fit into one another, resulting in a concave structure. this ‘half-object’, unfinished piece gives the user the opportunity to select a cushion of choice, whether it be floral, plaid, plain, dotted or embroidered, allowing them to have some contribution to the final appearance of the design. the owner is given control to determine the evolution of the object in time in terms of trends and patterns.
