Polypropylene stacking chair

The polypropylene stacking chair or polyprop is a chair manufactured in an injection moulding process using polypropylene. It was designed by Robin Day in 1963 for S. Hille & Co. It is now so iconic that it was selected as one of eight designs in a 2009 series of British stamps of "British Design Classics".

The polypropylene stacking chair is one of the very few chairs that, after over 50 years, is still in production and has been manufactured in forty countries around the world, for use in schools, hospitals, airports, canteens, restaurants, arenas, hotels, as well as homes.
