Very comfortable and I love the flip up arm feature which allows for a different style of chair. I purchased this chair because I have a stand up desk and with a goal of it staying in the tallest setting. HOWEVER, after two months the chair would no longer stay to the tallest setting while I sat in it and kept dropping down to the floor within a minute. It seems the cylinder was not longer good. I am well under the maximum weight allowed by the chair so that was quite disappointing.
