I do not recommend buying these chairs.  The metal parts were covered with dents and blemishes.  I contacted Sirio customer service as they requested in the instructions.  After three weeks I received a new chair from them instead of the replacement parts for the ones I had as we had agreed upon.  I contacted customer service again and was told they didn't have any inventory left.  So I put two chairs together, but it was terrible.  The parts didn't line up correctly and that made it very difficult to get them together and in a couple of places I'm not convinced they are safe.  I couldn't get the first part connected for the third chair.  I truly wish I had just returned them to Wayfair when I saw the poor quality of the finish.  I feel I did not get any value for the $260 I spent.
