All standing wheelchairs will be mounted on the armrest either into the unitrack under the armrest (if available) or by drilling custom holes. It is important to mount on the armrest in order to keep the device/tray level with the user whether they are in a sitting or standing position.
The standing wheelchair must always be mounted on the armrest. The Mount'n Mover will ride up and down with the user. This allows the mount to be in the proper position whether standing or sitting.
