Maybe the next step would be just continuing it on up.
Incidently, when I think of high quads and the difficulties of reaching and grasping I wonder if a joystick or similar controlled arm sort of like a backhoe-type shape but techy and not yellow and greasy mounted toward the front of the chair with a grasping device at the end would be useful for stuff like pulling something from the refrig, picking up dropped items, light switches, picking up clothes and doing laundry, cooking, etc. Some of these new robotic devices are pretty dextrous.
