The comfortable seat is made of crossed elastic belts, covered by polyurethane foam. The back is slightly elastic and comfortable. The upholstery could be entirely with fabric or leather (or eco leather) for the outside and fabric for the inside shell. The wide range of colours allows monochromatic upholsteries or bichromatic combinations, inside/outside. The legs can be powder coated to match the upholstery or they can be polished.
