This chair, which can be stacked up to twelve high, has a flexible, integral polyurethane foam body, available in four colours. Steel structure with back legs in tubular steel and front legs in silver-painted aluminium with a smooth surface. A supplemental hook element makes it possible to attach the stackable chairs to form rows or circles. The aesthetic trademark of .03 is its clear, simple lines. Thanks to incorporated springs, the upper part of the backrest moves under pressure. Available in a non-stackable version, with armrests or a chromed base.
