These are amazing and the price was also.  We had bigger people sitting on them, they are still working well.
The look is great and we are impressed by the smoothness of the system.  At this price point (+/-65$ each), we didn't find anything else that has a great look like these ones.  We saw some at double the price and the design was just plain boring.  These ones look like car seat and they are comfortable.  Only issue, we bought 6 but 2 of them didn't have the handle ends (the little things that screw on the the up/down handles).
