Hoveround MPV5 , this unit was purchased for my mom, but she used it one time when we took her on a cruise, so it was never used out side and only that once. I kept it hoping she would be able to use again it but she never did. There is no wear or damage to the chair. The unit looks brand new. The seat in 19.5" wide and 18.5 " deep. The back is 20.5" high and 19.5" deep. Since it was just sitting around and not being used the batteries went dead. I have replaced them so the unit is ready to go. The seat belt is long so you can adjust it for any size.
