Did the box for 4 years on a terrace, throughout the year, in the open air. No comparison with my similarly sized and old plastic, which has suffered greatly under the ultraviolet radiation and begins to crumble. This metal was pushed by the storm already three times from the terrace on the lawns and overturned. No scratches, upholstery remain stehts dry, looks like on the first day. Despite the high price and the lengthy assembly, I'm going to buy this metal for the second time and my scrap plastic.
