**Edited** After two years I expect some wear but on one chair the spring has already broken with normal wear. These weren’t expensive but still I would have hoped to get at least another year of use. 
Original review: I bought these for my dining room table and about six months later they still look great. I have had to tighten the screws a couple of times but with a ten year old boy using them I think that is to be expected for the price.
