Thread: Wheelchair dump, how much do you have?

  1. #21
    my new zr is 17w x 16d and 4 inches of dump. it's weird, but i feel much better in that setup than in my zra that was 17x17 with 5 inches of dump.

    someone feel free to correct me if i'm wrong, but you can't necessarily do a straight up comparison of two chairs based simply on the amount of dump. i think scott explained it a little better in another thread and it really comes down to basic high school geometry.

    Yeah, it's more an issue of seat angle.

    It's basic trig. Dump measurement = one side of a triangle, seat depth = another. The angle between those 2 sides will vary slightly between different seat depths w/ the same dump.

    Make sense?
