Beautiful and very comfortable office chair. Very solid construction. The chair itself is assembled very quickly. Only four stars because: 1. The "Blue" in the picture unfortunately is not entirely true. It is rather a very subtle dark blue. (But I was looking specifically a strong blue. Schade) 2. As mentioned here a couple of times it's a little silly that the backrests are not height-adjustable. 3. The chair is ratzfatz together, but for the rest you need "an eternity". Very, very bad instructions for this. You never know exactly where what comes out exactly. Send those responsible but even a week at a crash course to IKEA. Then it'll work well with a "simple foolproof instructions".
