I use this chair at work and when needing to upgrade my personal chair I knew there was only one option. And with it being on sale too this is a no brainer.
I've had this chair about a year now and it was fine until a few months ago when it started to lose chair height. I am not a tall person so keep the chair at maximum height it has started to slowly (over the course of a minute or less) lose height on a regular basis. It's awkward in meetings to be slowly sinking and have to readjust.
