2 of the 4 chairs make a crackling noise whenever anyone sits on them (regardless of weight - kids and adults alike)...and make sure no one puts too much weight on the front foot rest because they aren't made to hold much.  One broke since we've had them but Wayfair customer service came through and sent a replacement chair.  But for the price I'd say it's hard to beat this product, they look very nice and all in all the stools were just what I was looking for.
