I bought this chair based on all the positive reviews and have to admit, I'm a bit baffled by them. This chair has a stiff back with little to no lumbar support. After sitting in it for about a week, the seat cushioning is starting to flatten out and get lumpy. It also doesn't quite look as nice as the picture - seems cheaper looking. I wanted to return it, but could not get the gas lift off, so it won't fit back in the original box. My suggestion is to not buy an office chair online - only buy one you can sit in first.
