Early on, we were trying to find good ways to mount Steve’s Giraffe Cup and his cell phone on his power chair. Ram Mounts have a good wheelchair mounting solution. Because they specialize in auto and truck mounts, the mounts are stable, and they work well on a wheelchair. The base can be mounted on the arm with a few screws. We thought the cell phone holder worked well and would recommend it. The cup holder did not work as well.
