Within 2 years body depressions formed on either side, with a firm hump in the middle. When one of us is gone the other "hikes the hump" for better sleep. Yes we rotate the mattress, every month now. I contacted Serra for warranty information. They had a 3rd party, Mattress Marshalls, send a self-inspection kit. The "kit" was a string with a washer tied at either side to lay across the bed to measure depression depths. An unmade bed must sag 1.5" or greater to qualify. Ours only sagged 5/8". Sorry if this is boring but it's worth knowing. Every morning we wake up stiff. Never when I sleep at a hotel though.
