There are many companies that now sell “no-flip” mattresses, which feature designs that let you lay it down and essentially forget about it. But that doesn’t mean you should not rotate the mattress. Depending on who is sleeping on the bed, there are areas that will get more wear and tear over time. Rotating a bed can help keep wear even and maintain the overall shape of the bed. But how do you remember when to rotate? Whenever your clocks jump backward or forward, you should also rotate your mattress.
