Damage new mattress?

Hi NewtoMemFoam,

You can see the suggested rotation (for a one sided mattress) and flipping (for a two sided mattress) schedule I would follow in post #2 here.

There appear to be some lower quality materials in the comfort layers of your mattress so I would be especially diligent about regular maintenance to help even out any foam softening and impressions over time as much as possible
