What is a no-turn or no-need-to-turn mattress?
These mattresses are made with layers of fillings with greater resilience on the sleeping surface of the mattress. They are better able to stand continuous use of just one surface of the mattress, and therefore need less care by the user. They should still be rotated and flipped every month for the first 6 months to allow the fillings to settle correctly, and.rotated every three months thereafter.
