How Often Should You Rotate Your Mattress?

March 10, 2021 | Casper Editorial Team

You may change your sheets every week or so, and even refresh your duvet cover by the season. But when was the last time you rotated your mattress? That’s right—the whole thing, 180 degrees.

If it’s been a while, it may be time to flip your perspective on the usually stationary mattress. It just may extend the life of your bed, and create a better, more functional sleeping surface. From an innerspring mattress to a memory foam mattress, or even a latex mattress, mattress rotation will help with getting better sleep by preserving the mattress firmness. Read on to find out how often you should rotate your mattress and the benefits that come along with doing so. 

Rotation Frequency

The answer to “how often should you rotate your mattress?” depends on your mattress. 

  • For latex, fiber, and memory foam mattresses, opt to rotate 180 degrees once or twice a year, every 6-12 months.
  • Newer innerspring mattresses also need a rotation every 6-12 months.
  • Older innerspring mattresses need slightly more frequent rotation, at 2-5 times per year.
  • Casper mattresses deserve extra love and care because of the high mattress quality. Therefore, we recommend rotating your Casper mattress 180 degrees every 3-6 months.

The benefits of mattress rotation are well worth it as it’ll help keep your mattress fresh in the long run. 

The Benefits of Rotating Your Mattress

Ever wonder how long does a mattress last or how often you should replace your mattress? If you’ve been considered with mattress lifespan, mattress rotation can help. 

By rotating your mattress, you’re avoiding the following signs of mattress wear and ensuring the longevity of your bed: 

  • Lumps and bumps – By evenly distributing your weight across the mattress, you can prevent lumps and bumps from forming. Lumps occur when the internal structure of the mattress gets bunched up, so this is a risk for sleepers who toss and turn often.
  • Sagging – When you strip your mattress bare, always look for evenness. Any sagging, or lower parts of your mattress can cause improper back support—even if the mattress only sags an inch or two. If you tend to sleep on one side of the bed or sleep with a partner, you can stop sagging in its tracks with semi-frequent rotation. A sagging mattress is no fun, especially when you are trying to get a good night’s sleep. 
  • Hammocking – Have you ever climbed into bed, laid down for a good night of rest, only to roll towards the middle of the mattress by the time morning comes? This is called hammocking, and it can be prevented with rotation. It’s similar to sagging, but can wreak extra havoc if you’re a side sleeper—hammocking reduces how much hip support you get. Hammocking is also one of the clearest signs you need a new mattress, so make sure to rotate your mattress to avoid this.
  • Dust and wear – Rotating your mattress gives it a chance to breathe. Over time, mattresses are susceptible to collecting dust mites, dander, sweat, and can even mold in humid environments. By rotating the mattress, and therefore your sleeping spot, you’re fluffing up the mattress and never exposing the same spots to your body for too long. 

How Do I Know if My Mattress Is Flippable?

While you can rotate your mattress 180 degrees, some people also like to flip their mattress over entirely, switching which side faces the ceiling. Not all mattresses are made for flipping, though. It all depends on the material and make of the mattress. 

  • One-sided mattress – A one-sided mattress is built to have only one soft, sleepable surface. Flip a mattress that is really one-sided, and you could wear it out faster (and you may not sleep as well). Instead, stick to rotating your one-sided mattress.
  • Two-sided mattress – Two-sided mattresses are built from the core out so there’s padding on all sides. As a general rule, you can flip your mattress if it’s two-sided, typically made of a fiber-like cotton, wool, and polyester. Flipping a double sided mattress can help fluff and re-invigorate the fibers until it’s time to flip again. For mattresses like these, you typically want to flip every 6-12 months.

    If you’re flipping a fiber mattress, grab a friend! A double sided mattress can be unexpectedly heavy.
  • Pillow top mattresses – If a mattress has a pillow top, is made of memory foam, or has a hybrid design, flipping isn’t recommended. Flipping a foam mattress won’t do anything to refresh your mattress, because sagging and wear have more to do with the foam cells actually breaking down; they can’t bounce back as fibers do. 

Likewise, if you flip a pillow top or a hybrid mattress, you’re inverting the inner construction meant to support your back. This is the case with Casper mattresses—our strategically layered designs require the right side to be facing up so our technology can deliver the best sleep possible.
