I received the Ivy Upholstered Office Chair in Black with a Polished Brass base in exchange for my honest review. I LOVE this chair. My husband had it assembled in about 30 minutes and it is very sturdy and stable. The chair rolls easily over our floor and the lift mechanism works perfectly to adjust the height of the seat to your needs. The seat is very comfortable to sit on for long periods of time having a slight lumbar support. I like that there are no arms on the chair so that I can move in close to our desk when working, which I was unable to do with our old office chair. I highly recommend this office chair for quality, comfort and purpose, not to mention style.
