The user designed a harness that she sits on in her wheelchair. The harness has handles and can be fastened around the stomach and thighs with straps.
By using the harness during transfers, no one has to pull and lift by the arms or clothing. Transfers when using the harness also feel very safe and secure.
She uses the harness to be carried up and down stairs or during transfers in an airplane.
