Comments about Alera Interval Series Swivel Task Stool, PVC-Free Faux Leather, Black:
The chair was very easy to assemble, not many parts and includes the allen wrench=tool. Once assembled, moves easily on it's casters, at least while rolling over a floor mat or low-pile carpet. The pneumatic height control works well, allowing me to alter my arm position during the day. The seat and back rest are comfortable, although I'm only sitting for a few hours a day. The foot rest is a must with a chair this height. It is adjustable, but requires a manual adjustment, hence it is the only drawback I can find. However, I knew that when I ordered it and as I said, for the price, I'm very pleased with it. I ordered through Staples late on a Friday night and it arrived Monday morning! Super!
