"Luxury" hotel bedding is anything but, in my opinion. At least, I've never experienced bedding in a luxury hotel that was actually better -- as in more comfortable -- than that at less expensive hotels. The bedding in every hotel I've every stayed in is worse than my bedding at home, which is mid-range.
Interesting. Those articles make it sound like it's oh, so, wonderful and the hotel chains will actually let you buy it!
