What is it?

It's designed to hook over your foot and lift it. From your bed to the floor and from the floor to your bed.
It's a leg mover.
When you've had a knee op you can't move your bad leg on its own so for a few days this allows you to do so.
Why are you 'talking 'in this funny voice?
It's because I'm amazed anything so simple can be so clever.
Anything else?
Well I can go for a wee when I want to.......
Just in case I haven't been clear I've included an extra where ive had my head cut off,
