We were in need of a new mattress (ours was 18 years old) and in very bad condition. After doing some research, we decided on a Firm, pillow top. We've had it for 2 months, and already the mattress is sagging. We decided to go with a Sterns and Foster because of the reviews and it seemed like the Top of the Line product. $3,000 + and we are sorely disappointed. I'm happy there was a 120 day guarantee with it, we will go back to the store and select a different mattress. It took 10 years for our old mattress to start failing, this took 2 months. It started out really good, we slept better, felt supported, now we feel like we're on a hill toward the center. We will not choose the mattress without the pillow top for fear it will do the same thing. We will chooses a different brand, Sadly.
