Looking to get a new computer desk chair but its so hard to find the right one when I can't sit on it first to test it out. I'm looking to spend around $200. I did some searching and found these three that look pretty good and are within my price range. I'm leaning towards the Ikea markus since it comes with a 10 year warranty and I can go to the Ikea store and test it out first. Any other suggestions or recommendations?
