The chair is an excellent value for the money.  It is comfortable to sit in for most of the day.  It rolls easily - maybe too easily - and tends to scoot out from under your when climbing on.  The only real problem with this chair is static electricity.  Every time you get off, there will be a zap to anything metallic - even to the metal footrest on the chair.  Since I work with electronic parts, it means being tethered to a groundstrap to prevent damage.
