How can I store a memory foam mattress topper?

A memory foam mattress topper can provide a great way to improve the comfort of your mattress without having to purchase a whole new bed. However, these foam toppers need to be cared for properly, especially when putting them into storage. Taking the right steps when storing your memory foam topper will help keep it in good condition so it’s ready to use when you need it again.

Why Proper Storage Matters

Memory foam toppers are designed to contour to the shape of your body, providing customized support and relieving pressure points. The foam itself is quite sensitive and can be damaged if not stored correctly. Things like moisture, compression, and temperature fluctuations can all degrade the foam over time if you don’t take the right precautions.

If stored improperly, a memory foam topper may start to break down more quickly. You’ll notice it doesn’t bounce back as well when you take it out of storage. It may get flat spots or indentations where the foam has compressed too much. This can lead to lost comfort and support. Proper storage helps prolong the life of the foam so you get the most out of your topper.

The Best Way to Store a Memory Foam Mattress Topper

Follow these tips for keeping your memory foam topper in good shape when putting it into storage:

1. Clean Thoroughly First

Before storing your mattress topper, make sure it’s completely clean. Vacuum off any dust or debris using the soft brush attachment. Spot treat any stains or spills by gently dabbing with a mild detergent and warm water. Let the topper air dry completely before moving on to the next steps.

2. Air Out the Foam

Moisture is one of the biggest threats to memory foam. Let your topper sit out in a well-ventilated area for 12-24 hours before storage. This allows any built-up moisture in the foam to fully dissipate. Once it’s dried out, it’s less likely to develop mold or mildew while packed away.

3. Roll Up Gently

The best way to store a memory foam topper is by rolling it up. This prevents the kind of compression that can flatten sections of foam. Carefully roll up the topper starting at one short end. Try not to fold or crease the foam. Rolling tightly may damage the foam, so leave a little slack.

4. Put It In a Breathable Cover

Choose a large storage bag or plastic container that allows for airflow. The container shouldn’t squeeze the rolled topper. Avoid storing in completely airtight spaces like vacuum seal bags. The foam needs air circulation to prevent moisture buildup and off-gassing.

5. Store It Flat

Make sure to store the rolled topper flat rather than standing it upright. Laying it flat helps the foam retain its original shape rather than sagging under its own weight. Storing flat also keeps the roll from uncurling and expanding against any compression.

6. Keep It Cool

Temperature fluctuations can damage memory foam. Exposure to excess heat causes the foam to soften and sag. Freezing temps make the foam more brittle. Maintain a temperature between 60-70°F for ideal storage conditions. Avoid attics, garages, and other spots with extreme temps.

7. Use Moisture-Absorbers

Place desiccant packs in the storage container to actively absorb moisture. Silica gel packs work very well. Space packs out around the rolled topper and check them monthly, replacing any that become saturated. This keeps the interior environment nice and dry.

8. Store It Flat

Lay the rolled topper flat on a shelf or stack flat storage containers. Avoid standing it on its side or end where the weight can misshape the foam. Flat storage optimizes support for the full surface area.

9. Elevate Off Concrete

Avoid setting the stored topper directly on concrete garage or basement floors. The cold from the concrete can seep in, plus moisture from the slab. Place sheets of wood or cardboard underneath for insulation and moisture protection.

10. Use Within 6 Months

Try to use your stored memory foam topper within about 6 months. The longer it’s packed away, the more likely moisture and compression will degrade the quality. Rotate it out seasonally for the best care.

Other Memory Foam Topper Storage Tips

Keep these other pointers in mind when putting away your memory foam mattress topper:

  • Store in a dark place, as light can degrade the foam over time.
  • Make sure hands are clean when handling to avoid dirt or oils rubbing off on the foam.
  • Never fold or sharply bend the topper, as this can crack the foam.
  • Check periodically for moisture or mildew buildup.
  • Consider adding lavender sachets or cedar blocks to repel insects.
  • Never step directly on a stored topper, as body weight compresses the foam.

Using Your Topper After Storage

When you’re ready to start using your memory foam topper again after storage, allow it to air out in a room temperature space for 24-48 hours before placing it on your bed. This allows any trapped moisture to fully evaporate. The foam will return to its original shape overnight once laid out flat and allowed to expand. Enjoy the renewed comfort!

Know When to Replace Your Topper

With proper storage methods, a quality memory foam mattress topper can last several years. But there are some signs it may be time to replace your topper:

  • The foam no longer bounces back and retains imprints.
  • You see visible cracks, creases, or tears.
  • There’s yellowing or other discoloration of the foam.
  • You feel coils or bars through the foam.
  • There’s an odor like chemicals or mildew.
  • You see mold, moisture damage, or clumping.

If you notice any of these issues, it likely means the foam has broken down too much and won’t provide the same level of comfort and support. Investing in a new replacement topper can restore your bed’s sleep surface.


Caring for your memory foam mattress topper properly doesn’t have to be difficult. With the right storage techniques, you can keep your topper in like-new condition during periods of non-use. Roll it gently, store flat in breathable packaging, keep in temperature controlled spaces, and take other steps to prevent moisture or compression damage. With a little planning, your topper will be fresh and ready to use whenever you need an extra comfort boost.
