NO assistant is required, an audience member can be used.
Perform completely surrounded clear of back-drops or drapes!
2 Chairs are set face to face, with a long wood board on top.
A person lays on the board and is briefly covered with a cloth.
You remove the chair supporting their feet, they are SUSPENDED!
Wave below them, there's nothing to find!
The Magician then removes the board that the helper is laying on!
