If you feel like your mattress is sagging when you lay down at night, or if you can see dips developing on the top surface of the mattress, use your own discretion and rotate and/or flip it, so that a different part of the mattress gets more use. If needed, you could do this more (or less) frequently than every 3 months. Many brand-new mattresses, for instance, likely won’t need to be flipped or rotated right away, while many older mattresses will probably need to be adjusted more often.
When considering whether and when to flip your personal mattress, keep in mind that how you use it will partly determine how often it will need to be adjusted. For example, if you are using a mattress consistently every night, it is more likely to sag quickly, and you should probably adjust it every 3 months. Compare this to the mattress in the guest bedroom that gets used sparingly, which will not need to be adjusted as often (maybe every 6 or 8 months).
In addition, are you the only person sleeping on the mattress, or do you share it with a partner? If you’re the only one sleeping on it, you may start to notice dips or wear on the only side that’s being used. In that case, it’s important to rotate it to ensure that support and comfort don’t significantly diminish on that side.
Even if you do share a mattress with a partner, it’s possible that they are not the same weight as you, or they may sleep in different positions. In either case, rotating and/or flipping your mattress can help ensure a more even amount of wear on each side.
Adjusting your mattress, either through rotating or flipping it, helps add to the lifespan of your mattress. It aids in maintaining the quality of the mattress, by ensuring that support and comfort are not lost.
