What is the way to store a mattress topper?

Mattress toppers are a great way to add comfort and support to your mattress without having to purchase an entirely new bed. However, mattress toppers can be bulky and difficult to store when not in use. Properly storing your mattress topper will help keep it clean, undamaged, and ready to use when needed. In this article, we will discuss some quick tips for storing mattress toppers and provide more detailed explanations on the best storage methods.

Quick Tips for Storing Mattress Toppers

  • Store the mattress topper flat to prevent damage from bending or folding
  • Use a protective cover or place it in a sealed plastic bag
  • Store in a cool, dry place away from moisture and heat
  • Avoid storing directly on the floor which can cause mildew
  • Roll or fold lightly if storing in a confined space
  • If rolled, unroll and allow to fully expand before reusing

Properly storing your mattress topper will help ensure it remains in good condition so you can enjoy its benefits for years to come. Read on as we dive deeper into the best storage methods.

Storing Mattress Toppers Long Term

If you need to store your mattress topper for an extended period of time, such as in between college semesters or during a move, you’ll want to take some extra steps to keep it protected. Here are some tips for long term mattress topper storage:

Use a Protective Cover

One of the best ways to store a mattress topper long term is to use a protective cover or case. This will prevent dust, dirt, moisture, and bugs from damaging the mattress topper while in storage. Look for a cover made from a breathable material like cotton so condensation doesn’t build up inside. Make sure it fits the mattress topper snugly and zips or seals completely.

Put the Mattress Topper in a Plastic Bag

For extra protection, place the covered mattress topper inside a large plastic storage bag and seal it closed. This creates an airtight seal that prevents dirt and moisture from seeping in. Be sure to get a bag big enough to fit the entire mattress topper without having to squeeze or bend it. Remove as much air from the bag as possible before fully sealing.

Store Flat in a Dry Area

It’s important to store the sealed mattress topper flat rather than folding or rolling it tight. Lay it on a flat surface like the floor or a shelf. Avoid excessive bending and creasing which can crack or flatten the foam over time. Choose a storage space that is cool and dry like a closet, under the bed, or in the basement. Avoid humid attics or garages which can cause mold and mildew.

Use Mattress Topper Storage Straps

Specialty straps designed for mattress toppers can help keep them flat and evenly supported when storing long term. The straps wrap around the topper and cinch it tightly together without over compressing the foam. This prevents sagging or creasing damage. Secure with the attached buckles or velcro closures.

Rotate Occasionally

If storing your mattress topper for many months, rotate it over every few months to help it maintain its shape and support. Simply unlock the storage straps if using them, rotate the sealed topper 180 degrees, and re-secure in place. This occasional shuffling prevents indentation from the weight pressing down in one spot over time.

Storing Mattress Toppers Short Term

For short term mattress topper storage like when cleaning sheets or switching between seasons, you can get away with some simpler storage solutions:

Roll Up and Store Vertically

For storage times less than a month, tightly roll up the mattress topper lengthwise starting from the short end. Compress gently as you roll to expel excess air without crushing the foam. Stand the rolled topper upright in a closet corner or behind furniture. Make sure both ends stay elevated off the floor.

Fold Into Thirds

Lightly fold the mattress topper into thirds along its length and width. Try to avoid any harsh creases. Stand the folded topper upright in a closet or storage cube. Make sure all sides are fully supported and not drooping to avoid permanent creases.

Drape Over Furniture

For very short term storage like a few hours or overnight, simply drape the mattress topper over the back of a couch, folded chair, or footboard of the bed. This keeps it handy and avoids bunching it up too small. Just try not to let it drag on the floor.

Air Out Before Reusing

Whether folded or rolled, always make sure to completely unroll the mattress topper and allow it to fully expand for at least a few hours before putting it back on the bed. This allows any compressed areas to return to normal size. Give it plenty of time to air out any odors as well.

Where to Store a Mattress Topper

Choosing the right space in your home to store a mattress topper will help keep it in optimum condition. Here are some good mattress topper storage location options:


An empty closet shelf or vertical space works very well for storing mattress toppers when not in use. Closets tend to be cool, dry, and free of dirt or bugs that could damage the material. Stand upright or stack horizontally on a high shelf.

Under the Bed

Slide the mattress topper underneath the bed frame if you have at least 8 inches of clearance. This utilizes wasted space and keeps it handy for quick access. Just ensure no part of the topper is compressed or bent underneath the bed rails.

Attic or Basement

For long term storage, attics or basements can provide plenty of space. Just be aware of humidity and temperature extremes in these spaces. Make sure to seal the mattress topper in protective plastic sheeting if storing here long term.

Storage Chest

A plastic storage chest or under-bed container is useful for protecting mattress toppers in crowded spaces. Look for one large enough to lay the topper flat without folding or rolling tightly. This will minimize compression damage over time.

Garage or Shed

A garage or shed is not ideal for mattress topper storage due to potential for moisture damage and bug infestations. Only use these as a very last resort and keep the topper fully sealed in plastic and up off the floor on shelves or pallets.

How to Clean a Stored Mattress Topper

Over time in storage, mattress toppers can accumulate dust, dirt, and other allergens. Here are some tips for cleaning a stored topper before using it again:

Vacuum Both Sides

Use the brush attachment of your vacuum cleaner to thoroughly vacuum both sides of the mattress topper. This will remove dust, dirt, pet hair, and other debris that has accumulated while in storage.

Spot Clean Stains

Inspect the surface for any visible stains. Use an upholstery cleaner, mild soap and water solution, or baking soda paste to spot treat any dirt or stains. Gently dab or scrub the affected area, then wipe away residue with a clean, damp cloth.

Deodorize with Baking Soda

Eliminate any musty odors from storage by sprinkling baking soda liberally over the entire surface of the mattress topper. Let sit for an hour before vacuuming away. Baking soda soaks up and neutralizes odors naturally.

Disinfect with Vinegar

Mild vinegar makes an effective natural disinfectant for mattress toppers. Fill a spray bottle with one part white vinegar diluted in four parts water. Spray over the surface, allow to soak for 10 minutes, then wipe dry with a clean towel.

Air Out Outside

If weather permits, let the mattress topper air out in the fresh air for a few hours. The sunlight and breeze will help freshen and dry the material after cleaning. Just don’t leave outside for extended periods in inclement weather.

Use Mattress Topper Refresher Spray

Look for sprays made specifically for refreshing mattress toppers and pads in between cleanings. Spritz lightly over surface according to product instructions. Most provide antimicrobial protection and a light, fresh scent.

Common Problems When Storing Mattress Toppers

Here are some of the most common mattress topper storage issues along with solutions:

Creases and Bends

Solution: Always store flat and avoid folding or tightly rolling. Use light compression and support around rolled toppers. Rotate periodically.

Moisture Buildup and Odors

Solution: Make sure storage area is cool and dry. Use breathable storage covers and plastic. Allow to air out before reusing.

Compression Indentations

Solution: Don’t overload storage containers or shelves. Topper should lie flat without sagging. Rotate periodically.

Pests and Bugs

Solution: Seal in airtight plastic or storage bags. Inspect regularly for signs of pests. Clean thoroughly before reusing.

Mold or Mildew

Solution: Never store directly on concrete floors. Choose cool, dry storage areas. Keep covered and sealed in plastic.

Loss of Loft and Support

Solution: Avoid overly tight rolling, folding, or compression during storage. Allow to fully expand before reusing.
