I bought the floor model so there was no assembly which was a real plus for me. I'm using it to play the piano so I removed the arms with no difficulty. I'm very satisfied.
This is a nice looking chair with a lot of adjustment. Unfortunately the local staples store didn't have it on display so I ordered it without trying it based on the nice reviews. Assembly was quick and easy. However once I tried sitting in it it was clear to me that the chair is not deep enough thus it is uncomfortable to sit in. I figured it might still work for my kids. They however complained about the small size as well. I just initiated a return with Staples and will be exchanging it for a larger chair. This time I will go for a chair in the store so I can try it before I buy it :)
