I dunno, I went with their mattress recommendation (at least the one of three years ago, don't know what it is now) and lived it, it's the first mattress I've really liked since becoming an adult.
Mattresses are highly subjective, especially because a decent chunk of the population doesn't have particular requirements for one (i.e. no back or neck problems and general health make it easy to sleep on a rock).
However, there is a discrete consistency to picking a durable mattress that has advantageous qualities such as support and whatnot, and none of those mattresses are made of quality, durable materials that will provide lasting benefits for sensitive people.
