Some models need to be rotated now and then because by doing so, you would even out the overall wear and tear that the bed is subjected to. This is not only going to prolong the overall usability period, but it would help you keep your spine in a rather neutral alignment.
This is a critical aspect of getting a night’s sleep that’s good and relaxed. It’s also playing an important role in the prevention of wake-ups through the middle of the night.
On the other hand, flipping the mattress requires you to turn it on its other side. There are certain older beds which require this. Typically, innerspring models which have no pillow top could be flipped to enhance their prolonged performance as they're going to wear out as time passes.
Which is Better: Rotating or Flipping?
There is no one-off answer to this question. The truth is that there are different types of mattresses which would benefit from both procedures in different ways. For instance, if you have a pillow top model, it wouldn’t be subjected to flipping at all. Instead, you can even out the wear by rotating it.
The same could be said for other types. To put it in a nutshell – different models would benefit from different procedures, depending on their overall material compositions and constructions. This is something you’d have to account for, and the instructions are usually given by the manufacturer. Also, keep in mind that the majority of the new beds shouldn’t be flipped at all.
