These chairs leave rust stains all over the concrete where they sit. They were outside for two days and in a light rain and the next day as we moved the chairs a bit, we saw the rust stains and the rust actually dripping out of the chairs. As for comfort, they need a little pillow or something. I'm 5'6" and my back got a little sore from sitting for about 20 minutes. They look nice but the rust stains are nearly impossible to get off our pool deck and considering the cost of our pool deck, we need to make a better investment in furniture.
