Can I do Constructive Rest in bed?

Except when practicing CR with the Sleep Constellations (to be released by Dec. 2012), CR is best done on a firm surface like a floor with a carpet, rug, or exercise mat.

Our bed is a powerful stimulus. We might likely just go to sleep. Which is not a bad thing, but when we need a pick-me-up during the day the floor is better. Remember that CR is an opportunity to tune in, not zone out!
