The Pack of 4 Arlet Outdoor Chairs is made of polycarbonate, which is a very strong and impact resistant thermoplastic material. The transparent polycarbonate adds a touch of modernity and visual lightness to the piece. It will look perfect on covered terraces, hotels and restaurants. It is suitable for indoor and outdoor use, although we recommend to protect it from atmospheric phenomena. We recommend cleaning it with a damp cloth without using chemical products. Arlet Collection.
