Before tucking away your mattress for storage, it's crucial to ensure it's pristine.

A clean mattress prevents odors, wards off pests, and prevents mold, too. Here are the best pre-storage cleaning tips:

  • Vacuum: Start by vacuuming both sides. Use an upholstery attachment to remove dust, dead skin, and potential allergens.
  • Spot Clean Stains: Accidents happen! Use a mild detergent mixed with water, whether a spilled drink or a sweat stain. Dab, don't rub to lift the stain gently.
  • Deodorize: Sprinkle a layer of baking soda over the mattress surface. Let it sit for a few hours, then vacuum. This natural method absorbs odors, leaving the mattress fresh.
  • Air It Out: Before wrapping or covering, let your mattress breathe outdoors on a dry day or in a well-ventilated location to ensure any residual moisture evaporates.
  • Check for Pests: Ensure no signs of bed bugs or mites exist. If found, consider a professional cleaning.

Choosing the Right Mattress Cover

Selecting an appropriate cover is essential for protecting your mattress from potential damage during storage. Here's how to choose the best:

  • Material Type: Opt for breathable materials like cotton or polypropylene. Avoid plastic covers as they can trap moisture, leading to mold.
  • Zipped Covers: These provide all-around protection. Ensure the zipper is of high quality to prevent any unwelcome pests.
  • Waterproof Qualities: Consider a waterproof cover for security against accidental spills.
  • Size & Fit: A cover should fit snugly around your mattress. Too loose, and it might not offer ample protection; too tight, it could strain the mattress.
  • Durability: Ensure the cover is durable and tear-resistant, especially if you're storing the mattress for an extended period.
    While plastic covers are commonly used, it's essential to ensure that it doesn’t trap moisture, which can lead to mold. If storing for a long period, consider covers allowing the mattress to breathe while preventing particles and pests from settling in.

Before storing, clean your dirty mattress with an upholstery cleaner. For hybrid mattress types, ensure thorough drying. Use mattress bags to keep the mattress protected. Seal with duct tape, ensuring the mattress stays free from dust and contaminants while keeping it safe.

Storing a Mattress Flat vs. On Its Side

When storing a mattress, positioning plays a significant role in maintaining its structure and comfort. Here are the pros and cons of the two primary methods:

Flat Storage Unit:


Preserves the natural shape; weight is evenly distributed, preventing sagging or deformities.

  • Cons: Requires more floor space, which may not be feasible in a smaller storage unit.
  • On Its Side:
  • Pros: A Place-saver, allowing for more room in storage areas.
  • Cons: Long-term vertical storage can cause materials to settle, leading to lumps or unevenness.

Storing on its Side: Short-term Solutions

While keeping a mattress on its side can be a location-saving option, it should only be done for short periods. Extended sideways can risk damaging the inner workings and compromise the mattress's comfort level.

Before moving, properly store your spring mattress using a mattress bag, fully covering it. For extra protection, wrap with plastic wrap. If using a pickup truck, ensure interior materials are safe to store items. Prefer a covered moving truck. Sprinkle baking soda on the mattress topper for freshness.

Space-Saving Storage Solutions

Maintaining a mattress in a safe place without compromising on space can seem challenging, but with the right solutions, it becomes effortlessly manageable. Here are some efficient stowage strategies:

Under-Bed Storage Boxes:

  • Designed to fit snugly beneath beds, these boxes can house foldable mattresses or mattress toppers, keeping them accessible yet out of sight.

Vacuum Seal Bags For a Memory Foam Mattress:

  • Removing air drastically reduces the mattress's size, which is especially useful for foam or memory foam mattresses. Ensure they are re-inflated gently to avoid damage.

Loft or Attic Storage:

  • Transform unused overhead spaces into places where the mattress will be. Just ensure they're free from dampness and pests.

Wall-Mounted Racks:

  • Some innovative designs allow mattresses to be stored vertically against walls, with protective barriers to prevent damage.

Storage Units and Storage Facilities:

If on-site solutions aren't feasible, consider renting a climate-controlled storage unit specifically designed for mattresses.

Considering storage facilities, l is an excellent choice. A climate-controlled storage unit maintains an optimal temperature, preventing humidity levels that can harm the mattress's materials.
