This chairs work great in our home office. They match the style of my other office chair (somewhat modern as well as slightly casual-which gives welcoming yet professional feel). They are comfortable even for my 6'3" fiancé. But, they don't take up a lot of space. They are fairly lightweight, but not cheap or flimsy. I found these chairs to be easy to put together, with one small exception (I think at the factory...one of the workers may have mixed their drill bits on the pieces they had to drill, because on both chairs, in the same location, I had to reverse the screws that go into the back and the screws that go into the seats (as they would not thread b/c the screws could not reach the metal thread inside until I switched the screws). Otherwise, these chairs are great w/ mesh-like material backs and foam padded-fabric covered seats. Also, I found that CAN stack them if needed. They do not roll, and it seems like it would be tricky to add rollers on your own, so I wouldn't advise considering doing so unless you have Liam Neesan type Special Skills!
