designer's own words:This chair is intended to be easy to produce and keep beauty as well. The seat is one piece injected in polypropylene (other plastic could be used if necesary) with a high gloss finish for better cleanability so the chair can be used indoors or outdoors. The legs are a couple of tubular rolled formed legs in hardened steel. These are fixed to the seat by four screws and a mounting plate that keeps united both legs and limits its possible movement keep it robust. The seat can be injected in a wide variety of colors and finishes.
