Because it sleeps GREAT! My husband and I are in our late 50's, he likes a firm mattress and I like a mattress a little softer, he sleeps on his stomach and I sleep on my side We got rid of a Stearns & Foster and feel like we've definitely traded up with your mattress. Your mattress is as advertised! Remember, it's not bragging if it's true. And, your claims about the mattress are true.
A little too firm so far, hopefully will get better as I sleep on it more. I weigh 100lbs and my girlfriend weighs 70lbs, maybe were are just too light to sink into the bed, I'm sure somebody heavier would be more comfortable.
It's been less than 2 weeks since we got it. So far it's been everything we hoped it would be. Too soon to know if the memory foam will hold up for the long term.
