I have back problems and had been looking for something to really support my lower back. This chair has GREAT back support! I put it together in about 20 minutes very easy even for a 58-yr-old woman. Because I work at an L-shaped desk I decided to put on only one arm and leave the other side open to my desk. I also didn't put on the head rest. Not having all the pieces on the chair hasn't degraded the performance of the chair whatsoever. The chair has the ability to rock but I keep it locked in place. It still allows me to rock a little without really leaning back. I found the rolling casters are lower to the ground than my previous chair so I can open my file drawers without bumping the corners of the drawers or having to make sure the chair leg is out of the way. It's so comfortable! The mesh makes it cool and not sticky like some leather chairs. I do find that it can get a little uncomfortable wearing shorts and sitting on the mesh for any length of time because of the mesh pressing into the skin but the most people don't wear shorts when working. Having the slope at the front of the seat is very nice. I can cross my ankles and there's no hard edge digging into my legs. I bought a more expensive chair about 6 months ago. I wish I'd round this first.
This chair suited my needs perfectly. It sits slightly higher than my previous chair which was necessary for my new office location. Also it is incredibly comfortable to sit in for short or lengthy periods of time. The lumbar support isn't as adjustable as I anticipated it would be however it is still really comfortable and the ability to adjust that at all was a plus in my book. Definitely would buy this chair again if I am ever in the market for another chair in the future.
I am very pleased with the comfort of this chair. Assembly directions were clear and assembly itself was not difficult at all. The back supports my spine and the ability to lean back helps to massage your back from time to time. I would recommend this chair.
