So, I have a Stearns & Foster Nottoway firm mattress with pillowtop that was purchased a little under 2 years ago. The pillowtop has basically collapsed and Sleepy's has issued me credit for a new mattress. I do NOT want to go with a pillow top again as I just don't trust them anymore.

In order to keep my full warranty in effect (not replacing box spring as it is fine) I need to pick another S&F mattress and have no idea what is out there today.

My wife & I are both side sleepers, and I have neck/back injury.

We both like a firm mattress but comfort is also needed.

Queen size.

Thoughts?
