This chair has a 7ft.  Elevation. It’s able to Recline, Tilt, Leg lift, etc. This chair can move up to 6mph with rear drive. Back rest seat support for quadriplegic support. Also comes with ROHO seat for extra bottom support. Will prevent and help heal pressure sores if any. Power knob for steering can as well swing away for extra room to grab things. Arm rests are able to swing upward to allow transfer to different surfaces. Foot rest can swing up and leg rest can be elevated to help with swelling or blood pressure regulation. As for driving; this chair can move at a normal speed through grass or tough terrain! Standing can be added if preferred. If you’ve had or know of anyone who have had a traumatic, brain injury, or spinal cord injury. Elevation is great for reaching into high cabinets, or even just going into the freezer. I love this chair! It can hold up to 350lbs in weight. It is able to be put into manual to be pushed when or if it gets stuck. Whoever the buyer may be you’re going to love this chair.
