These chairs are very sturdy and very comfortable.  Assembly took a little more time than I had hoped and I used a cordless drill and driver bit rather than the tiny allen wrench provided.   But, it went well and we love these chairs.  We put them in our new pergola with the glider bench made by the same company that we also purchased from Wayfair. The "wood" material is much nicer quality than we had expected, so even better!
