That concerned me too. That was one of my first questions when the Whill salesman brought the demo for me to see. It does have tie downs. We use them with our Bruno lift. My ECV never shifted on the lift, but the Whill does. The Whill is of course much shorter in length. I think maybe there is a legal issue with calling them tie downs - as this is not an FDA approved device. But they are quite sturdy. They effectively keep it in place with 4 tie down places.
