It is a good looking comfortable seat. I'm thankful that the tension coil is adjustable because the default setting was fully tightened and it was rather stiff but loosening the spring has made it easier to lean back but it doesn't lean very far. Safety allowed I guess. Assembly wasn't too bad: it is a well thought out process with excellent directions easy to follow and generally easy to fit all the parts together; the only thing they don't tell you is that it's best not to tighten the arm screws until you have all the screws for each arm at least partially screwed in. Then crank them tight and all's swell! I'm very happy with the chair now that I'm using it the only thing to see is how long that remains true. Be positive: it will probably be part of my estate.
i like it was easy to install it just follow the simple instructions. the only thing for safety issue doesnt let you lean back that much only slightly. very comfortable chair since i sit on it almost 10 hours a day.
The user (a relatively small person) likes the chair; however it was a necessary purchase due to the failing of the hydraulics on the first chair purchased (within the past 3 years). I hope this one lasts longer.
