I have purchased many chairs for my home office during the past 50 years and this is the most comfortable chair I have every owned. The fact that the arms can be lifted to be behind me instead of at my side I find to be a quite useful feature. There is nothing about the chair that I do not like and I highly recommend it.
This is a really nice chair. It wasn't quite as easy to put together the final piece / back as I thought it would be. Really make sure you are actually in the threaded hole - its not the easiest. But got it done and seems well built and high quality.
My girlfriend loves this chair. She has even given the chair a pet name. She calls it the White Knight. Primarily she uses it for sitting at a table doing crafting projects. Its very comfortable and sturdy.
With a back tall enough to rest one's head back comfortably padded arms and a comfortable seat this chair is great! I got one last May but there wasn't an option for white/gray only blue/black and red/black. They just came out with white/gray and my wife said YES! I got it for her. Problem is I'm jealous as it fits our decor SO much better. Dang! If only...
