This is our second Stearns and Foster mattress. We loved our first one but when it needed replaced, we decided to try a memory foam mattress. That was a big mistake! That bed was only comfortable for less than a year. We just replaced it with a new Stearns and Foster and couldn't be happier. We are sleeping much better, have less hip and back aches through the night, and we know this mattress will last much longer than the memory foam one we had.
