Exceptional quality for the price. We have had a few kids stand on them and they seem to hold up, although over time I could see that the material may sag with sustained heavy weight. When it rains, water pools on them, but easily slides off with a quick tilt of the chair. The aluminum scratches, so dont leave them on their sides against rough surfaces like bluestone. They have many recline positions and also lay flat. Very comfortably and not too low to the ground. We get so many compliments.
