Bought this chair to work from home. It's pretty standard and serves the purpose. After a year it is no longer holding its height positioning. I set it to the highest setting and it slowly sinks over the course of an hour. Unfortunately now unable to return.
Nice looking chair and very easy to assemble. Excellent instructions & warranty. Excellent (fast & free) shipping. I would have rated it a 5 but it is a little firm for me...a little uncomfortable after sitting a while. But that's a personal preference/issue.
