This chair offer features that are rare in others. Actually I could not believe that way more expensive chairs does not offer same or better features. Beside being one of the cheapest it is reclining and stopping at your preferred position not like other high or low. I can't really explain it but I bought two of these for my son and me and we are both happy with them. We had them for two weeks now so I do not know how durable they are.
I purchased this chair as a replacement for the one I was using at work. I've had flare up with tendinitis so it was important for me to find an ergonomic one with adjustable seat arms and tilt since I'm at my desk all day. The Staples Carder had the right requirements and was a great price on sale ($99.99). It was fairly easy to assemble and took about 20-30 minutes. The allen wrench comes in the same little packet as the screws so just don't forget about that (I almost threw it away not realizing there was something still in there). This chair isn't lounge-chair comfortable (of course it's not -- it's an office chair) but it provides the ergonomic support I need for desk work.
