Please search for hil bichovsky bandcamp.

There is a 5 minute seated relaxation - intended for use at work at a desk, or in a chair. And there is a 30 minute lying down guided deep relaxation of the type we do at the end of a yoga session.

(Sorry,I can't work out momentarily how to add a direct link here, but usual search engines should find it. Please email me at hil.b@:zen.co.uk if there's a problem.)
