I have always enjoyed the Westin beds more than the more recent Marriott beds (haven't tried the Revive beds yet though). From what I've read here and elsewhere it sounds like the Heavenly Bed is the standard to which the others try to measure. As a result I've ordered the Heavenly bed today - they don't give 'em away however, at $1350 for mattress & box spring (no frame). The linens cost almost as much.
