I got hooked on one hotel chain years ago because of how well I slept -- all because of the damn bed.  The Westin, owned by Starwood, has made their Westin Heavenly Bed a major point of difference.

I mean, listen to this description. C'mon!

The Westin Heavenly Bed is uniquely designed with a plush, pillow-top construction for premium comfort and support. Slip into the Westin Heavenly Bed and experience a night of restorative sleep that is simply divine. 

I'm drooling over here.  In addition to the mattress and boxspring, you can also take home those Egyptian cotton sheets and delicious down blanket.  By allowing guests the opportunity to take the Westin Heavenly Bed home, they have taken the experience a step further creating more brand loyalty in the process.

And, a quick side note, W Hotels, also part of Starwood, also sells their beds online.  If you've had a great hotel bed experience, leave me a note in the comments.

Right now, I'll be over here dreaming about that bed.
