We desperately needed a new mattress about a year ago. I wanted a Temperpedic mattress. I wasn't sure my DH would go for it because it is a little bit pricey and he doesn't like to try new things. I have never regretted spending the extra to get it. We have loved it from the day we got it. I am 60 and my hips, knees and back feel so much better. They do have a 90 day money back guarantee. But you do have to buy something else from them I think. If I ever need another mattress it will be the same brand. My son has another name brand of memory foam mattress. It is comfy but not as good as ours. Ours also has something to make it feel cool. My sister has one that is about 20 years old that she still loves. And my sister is a whiner and complainer.
