These chairs are Heavy Duty and are well made. However, I wish there was a color choice on the cushions. They come well packed and are very easy to assemble, with just 4 wing nuts and lock washers to apply. The stools will swivel, but only as a result of the threaded spindle. The threaded spindle serves as a height adjustment as well as the swivel. This method of swivel, is probably better than a ball bearing race, since ball bearings are subject to dirt/dust and rust, if not properly sealed and lubricated. The pipe design is kinda cool too. I believe these chairs will last a long time.
