Tube is a chair with soft shapes that reafirms its industrial origin, with lines that inspire movement, humanization of the object and even humor. Beauty and comfort are values integrated in the design. Clean forms that seem to be drawn in the air with lines made by a continuous tube of steel and topped with a seat made of polypropylene. Tube is a chair that intentionally hides its merits. Plain design on the outside, smart on the inside: resistant, suitable for indoor and outdoor environment, stackable and easy to maintain.
