How to Store a Mattress Topper

Lara Vargas


Mattress toppers can be a much-needed addition to a mattress for a variety of reasons. They can help change the firmness of a mattress, enhance comfort, and add extra support. But, just like a mattress, proper storage is essential for prolonging a topper’s lifespan, and there are key things to keep in mind when you’re planning to store one. Here, we’re sharing steps for how and where to store a mattress topper, signs it’s time to replace it, and the benefits of using one.

1. Clean and Dry It Thoroughly

Before storing your mattress topper, you’ll want to thoroughly clean it to get rid of any dirt and dust mites. If these particles become trapped during the storage process, they can damage your mattress topper while in storage.

How to Clean a Mattress Topper

  • Remove all bedding: Remove any bedding or covers from the mattress topper.
  • Vacuum: Use a hand-held vacuum to remove any loose hairs, particles, and other debris from the outside of the topper.
  • Treat stains: If you see any stains on the topper, spot clean them by using a mild cleaning solution. Blot the liquid up with a towel and repeat until the stain is removed.
  • Treat odors: Sweating, spills, and other accidents can cause odors in a mattress topper. Treat these by sprinkling baking soda on the surface of the topper and letting sit for an hour or two before using a vacuum to remove it. For more persistent odors, dissolve baking soda in water and gently rub into the area of the odor. Use a damp cloth to remove the mixture. Then, blot with a dry towel.
  • Air dry: To make sure your mattress topper is completely dry, allow it to air dry for 24 hours. Making sure the topper is completely dry before placing it into storage is very important because any trapped moisture can cause mold and mildew to grow.

2. Roll It Up

When your mattress is completely dry, rolling it up will save space in storage and make it easier to move. You should never fold your mattress topper because the pressure from folding can cause creases that can ultimately damage the foam and render it useless. Instead, always roll your mattress topper when storing it to prevent creasing and damaging the foam.

3. Use a Protective Storage Bag

It’s important to use a protective storage bag when storing a mattress topper to prevent dirt, dust mites, and liquids from causing damage. If you have the original bag the topper came in, you can use that. The best storage bags for mattress toppers are those that vacuum seal shut because they save space and keep dirt out.

If you don’t have the original packaging, you can also use a plastic mattress bag and vacuum seal it. Otherwise, wrapping the topper in protective plastic and securing with heavy-duty duct tape will work to protect it.

4. Choose a Climate-Controlled Storage Space

The best place to store a mattress topper is in a climate-controlled environment because a dry and cool climate is ideal for preventing mold or mildew growth in the topper. In warm, humid climates, mold and mildew have a much higher likelihood of thriving.

If you have space in your house to store your mattress topper, choose a dry area of the home, like a spare bedroom or closet, where dirt and liquids are not likely to get to it.

You can also opt for a climate-controlled storage unit. These are great for storing any type of furniture or mattress because the temperature and humidity levels are maintained year-round. These storage units are also usually located indoors, keeping dirt and rain out.

When to Replace a Mattress Topper

Toppers will not last as long as mattresses because they’re much thinner. However, you can usually expect a mattress topper to last anywhere from three to five years. The level of quality, thickness, and care will all affect a mattress topper’s lifespan. If you’re on the fence about storing your mattress topper or replacing it, consider these two factors.

Wear and Tear

One of the most common signs of wear with mattress toppers is thinning of the material. This happens over time when the foam begins to break down due to being slept on. As this happens, the topper will become too thin to serve its intended purpose. Other signs that it’s time to replace your mattress topper include visible holes and tears in the material.

Set-In Odors

If you’ve repeatedly tried cleaning your mattress topper only to discover that odors and stains won’t budge, it’s probably time to replace it. Set-in odors can be a sign of mold or mildew and can eventually transfer to your mattress and other bedding. Mold and mildew are a hazard to your health and sleep quality, and you should toss your topper immediately if you suspect the presence of either.

Benefits of Using a Mattress Topper

If you have a mattress whose firmness and support is not quite what you’re looking for, adding a mattress topper can be an affordable fix. Toppers have a multitude of benefits that can improve your sleep quality and protect your mattress.

Custom Firmness

Mattress toppers are a great way to adjust the firmness of your mattress without having to spend the money to buy a whole new bed. If you find that your mattress is too soft, adding a topper can firm it up to better suit your preference. On the flip side, if your mattress is too firm, you can add a topper that will make the sleep surface much softer.

Enhanced Comfort

The extra cushioning of a mattress topper can offer a more comfortable sleeping surface. Some toppers with cooling technology contain gels to help you stay cooler at night. Features like these can prevent night sweats and regulate body temperatures for a better night’s sleep.

Added Support

Adding a mattress topper to your bed can increase the level of support it offers. The cushioned layer of the topper reduces pressure on your body which in turn, can improve sleep quality and muscle or joint pain. Some toppers also feature zoned support that adds an extra level of firmness where you need it most, like under your hips and lower back.

Helps Protect Your Mattress

Using a mattress topper can reduce the direct wear and tear to your mattress. While they’re intended to add extra comfort, toppers can act as a buffer between your mattress’s surface. This can keep stains, spills, and physical damage away.

Helps Extend the Life of Your Mattress

Mattress toppers can help reduce indentations and sagging in your mattress’s comfort layer which can extend its lifespan. But, it’s important to know that toppers can’t reverse the effects of indentations and sagging that are already present. Toppers are specifically designed to modify a mattress’s feel and they cannot miraculously fix an old one. If you notice lumps and bumps across your bed’s surface, it’s time to replace your mattress.


Can I fold my mattress topper?

You should never fold your mattress topper because folding can cause creases. Pressure from the creases in your topper can damage the foam and ultimately render it unusable. Instead, always roll your mattress topper up. This will prevent any damage or creases from occurring.

How long do mattress toppers last?

A high-quality mattress topper generally lasts between three to five years while lower quality ones will last even less. Additionally, a thinner topper will wear out quicker than thick memory foam, because thicker foam takes longer to break down. Other factors affecting a topper’s lifespan include how frequently it’s used and the amount of weight being placed on it. Frequent use and a heavy amount of weight will wear down a mattress quicker.

Can I vacuum-seal a memory foam mattress topper?

Yes, you can use a vacuum-sealed bag to store your memory foam mattress topper. These space-saving bags are great for storing mattress toppers because they keep dirt and dust mites out. Generally, mattress toppers come in vacuum-sealed bags.

What’s the difference between a mattress topper and a mattress pad?

Mattress pads are usually less than one inch thick and are used to add a layer of plushness to a mattress. Many are machine-washable and some materials can help protect your mattress from spills and liquids.

Mattress toppers are usually much thicker than mattress pads and more effective at offering protection from wear. They are used to alter the feel of a mattress, enhance comfort, and add support. Often, toppers are made out of the same materials as mattresses like memory foam and latex. This, however, makes them more difficult to clean and store than mattress pads.

When should I replace my mattress topper?

You should replace your mattress topper when you begin to see signs of the foam material thinning out, or if you spot any holes or tears. These things can occur over time from normal use and eventually, the topper will no longer be able to serve its intended purpose.

If you suspect any signs of mold or mildew, you should get rid of your topper immediately to prevent it from spreading to your mattress and bedding. Mold and mildew can negatively affect your sleep quality and overall health.


Knowing how to properly store a mattress topper can prevent it from any damage and prolong its lifespan. While high-quality toppers can last up to five years, it’s important to know the signs of one that needs replacing in order to protect your health and mattress. A well-maintained mattress topper can provide many benefits that promote a good night’s sleep.
