Lovely chair, I worked for 10 hours straight in it and found the seat to be comfortable. It was super easy to assemble. I have to return it, as for my height and thus desk needs the chair doesn't go high enough up and I need a lumbar support pillow for better ergonomic position. Note that you would need to have a mat on a floor if you intent to use it on medium or thick carpet as the wheels don't turn well in that scenario. (I don't think they were designed for carpet). In short, the chair works and delivers for what it was designed.. which is a lovely decor item for 2-3 hour a day desk job.
