While most modern mattresses don’t require flipping, there are many benefits to flipping traditional ones. The best way to keep your innerspring mattress in good shape for longer is to maintain its coil system. Flipping your mattress can ensure even weight distribution and prevent coils from breaking. If you have a flippable mattress, constantly sleeping on only one side can wear it out faster. Flip it occasionally to allow each side to recover evenly, increasing your mattress’s lifespan. Over time, mattresses tend to sag in the middle, negatively impacting your spinal alignment. Luckily, flipping your mattress can remedy this problem quickly. Follow these steps when flipping your mattress. If your mattress is on the heavier side, don’t hesitate to ask for help when flipping it.
