Would be interested to hear more followup impressions from owners who have had the bed for a few years. My main concern is that the bed is beguilingly soft and comfortable for a night but less so long term. I've also read some posts on other forums suggesting that there might be sagging or other issues long term, but I'm not sure if they've been successful in claiming the warranty.

I've never stayed at a W but I remember that the Westin I stayed at a couple years ago had one of the most comfortable beds I've slept on. Seems like there's a hypothesis that W beds are the plush+featherbed and the Westin beds are the pillowtop model? The specs are awfully similar. Both king pillowtop bed are 13" and 1056 coils. Can current owners comment on whether "W Hotels" or "Westin Heavenly" is embossed on the top of your plush or pillow top?

Really debating which one to get and not quite sure I want to spend $200 to test drive the W bed for a night while not on the road. Leaning towards plush with a potential featherbed topper.

I'll be using my bed in a platform bed application, so I'd also be interested to hear if there's any significant difference to using the mattress alone vs. with box spring.
