That's also exactly why Casper and a half dozen other upstarts have come out with the memory-foam mailed-to-you-in-a-vacuum-tube online mattress sales.
The conclusion of the podcast was "If you spend $800 you're probably safe, below that it's hard to know if it's good or awful. Above $1500 is too much."
Considering Marriott/Hilton/IHG requires their hotels to use a 10 year warrantied mattress that only costs $250-$300 each, I'd say even $800 is too high. Even though that's wholesale price, doubling should be enough to get a single unit price.
People would be better off investing in some HIIT cardio excercise if they're looking for a good night's sleep. And eating less / more nutritious food.
The extra $300 is what you pay for going with a reputable brand, because unlike Marriott, you don't have the time to figure out which off-brand mattresses are crap and which aren't.
In that case, your assertion that "doubling should be sufficient to get single unit price" was wrong, cause you aren't going to get a queen from either of those companies for $500.
