Transfer boards are used to reduce the risk of falling between the seat and wheelchair when transferring into and out of the car. A typical transfer board is permanently installed and folded out of the way when not needed. There are also semi-permanent boards that attaches to a permanent bracket in the car. Finally, there’s the completely portable transfer board. However, there's a big benefit of a permanent or semi-permanent installation. Transferring to a fixed point greatly reduces the risk of falling as it cannot slide away during transfer.
