The chair is comfortable for sitting a long time at your desk. The easily adjustable lumbar support is appreciated. The chair is also very light to move around in front of the desk to reach places to get needed supplies. The wheels easily roll over the edges of the floor protector that is also appreciated. The chair adjustment for leaning back to relax is also easy to adjust. The mesh surface prevents a sweaty seat and back. Assembly is very simple by using only an included allen wrench. The directions and separate packaging for all the well labeled parts are exceptional. These are the best organized directions I have ever used. There is one step where having a second person to help hold one of the parts being assembled would be very helpful.
