I purchased this chair to replace a leatherette chair that was flaking and falling apart. After reading some reviews and doing a bit of research I settled on this Brennen product.  I'm 220 and spend many hours in this chair each day designing web products.  This is a REALLY, REALLY comfortable chair that took less than 30 minutes and one ice cold Miller Light to assemble.  The only problem that has so far surfaced is that my girlfriend keeps trying to "bogart" it for her office.  I'm thinking of putting a small cable lock alarm on it.
