If you happen to get a hoveround chair, at least on the "MPV4" to make the seat recline, on the left side (as you are sitting in the chair) at the hinge for the back of the chair there are 4 drilled & taped holes. If "your" chair does not recline, remove the stop screw in one of the holes. Thats It!. It'll now recline. Hoveround wanted $500. To remove that screw 5 years ago. Of corse they won't tell you what's needed to make it recline.
