Hey folks, my comfy old air mattress has blown a gasket. I'm looking for a new uber-luxury camping mattress. Weight is not an object, but it has to shrink down into a sleeping bag size for transport. This is not for on-my-back wilderness work; it will be schlepped around in a car or canoe.

I will pay good money for something that is "hotel comfortable" and will last for 10 years. No wally-world rubbish need apply.

Recommendations?
