I've used this model for over 3 years following back surgery.  It has been adequate, I'm tall, 6'5",  the chair is not quite long enough.  The footrest has room for improvement, the angle at the up postion is too low, and my legs hang over the footrest by about 6 inches, where normally your heels should just over hang.  Lately the chair has started having control issues, almost like a motor postion sensor is not making, normally one push on the controls and the chair moves all motors at the same time, now I have to move one function, then the single button push may work.  The chair covering has held up well and I'm rough on it.  Overall its been a good buy, I didn't have a lot to pick from when I bought.  I would say for a person 6' or less, and if you don't mind using a pillow on the footrest, it would be a nice fit.
