My wife and I do 35 Marriott timeshare nights a year along with another 30 hotel nights a year. All I know is that we sleep damned good on those mattresses and we always remark to each other how Marriott's mattresses are far superior to our own sucky mattress. We're going to do something about that in January when we do some work on our master bathroom and bedroom and a new Marriott mattress is near the top of the list.
