I just purchased this chair because I wanted to try a desk chair without arms. This chair is not as comfortable as my other chair and It does not roll at all on carpet. This chair  is not made of leather. My last chair I purchased from Sam's Club (Serta) was very comfortable and rolled all around my rug with no issues. I do like the look of this chair. It is somewhat comfortable. This chair raises up and down really well and swivels nicely. I will keep it since I paid $180 for the chair but it has taught me a valuable lesson when buying a chair you sit in often, to do it person to make sure it is comfortable and glides easy on any surface! I did ask a couple of questions to Birch lane before purchasing this chair and I must say that they answered my questions as quickly and accurately as possible.
