I’m sitting on an Aeron at work, it’s good, but I can’t in good conscience pay that much for a chair. I was recently on the market for a new office chair and extensively researched it. It really looks like it’s a hit or miss with every chair in every price range, and I was very seriously considering replacing my Hyken with another Hyken. I decided to go with the IKEA Markus and have been sitting on it for about a month. I’m only moderately happy with it, may even return it before the year is up although I’d hate doing it.
