The key is to adjust the footrest and move it higher (it always goes down too far when it's set to the flat position) so that ones feet are always on it to avoid sliding. And, of course, wear non slippery clothes.
I can rarely sleep in any moving device. And I can only sleep if the surface is completely flat (otherwise highly uncomfortable and outright impossible to really sleep). The WBC seats however - with the footrest adjusted to avoid slippage - are very condutive to sleep.
