The Heavenly bed is the signature bed of the Westin hotels.
Is it comfortable? For a hotel bed, it's one of the most comfortable I've ever slept in. Soft but supportive at the same time. It's not just the mattress and springs, it the entire package. The duvet was really nice. The pillows were VERY comfortable!
But frankly my Sealy Reflexions mattress and springs are much more comfortable. JMHO.
