Tempurpedic vs Memory Foam Mattress? Which is better?

I need to get a new queen mattress. Should I spend the money on a tempurpedic or is their a generic brand that sells the same quality for cheaper. I don't want to buy the name, I want to buy a good mattress. Any suggestions?

The fake ones are of much lesser quality.the foam will break down and fall apart.I bought a Tempurpedic mattress about 15 years ago,and it is the best money I ever spent.You spend a third of your life on it.It is like sleeping on a cloud.Go for the real thing.You will not regret it.Stay away from a pillowtop tempurpedic.It defeats the purpose of the benefits of the mattress.
