How To Store a Mattress Properly?

Whether you have a guest bed you put away for months at a time or a new mattress that you are saving for a new home, there are plenty of scenarios where you might need to store a mattress for extended periods.

The good news is storing a mattress is relatively easy, but you need space for it, and this is the biggest downside to mattress storage. Also, you may need to buy a mattress storage bag to protect the mattress from dust and dampness.

Here’s how to store a mattress properly:

Storing an old mattress

If your mattress is used (i.e., not new in packaging), your storage prep will be a little longer than if the mattress was new.

The best way to store an old mattress is in a storage bag, which envelopes the mattress in sturdy, waterproof plastic.

You can store your mattress anywhere, including in damp basements, providing you get an airtight seal on the mattress bag. However, storing an old mattress in a dry environment is always best to prevent mould growth.

It would be best if you also cleaned your mattress. Our mattress cleaning guide has all the steps you need – you must first determine whether a dry or wet clean is needed and use neutral cleaning agents to prevent long-term fibre damage.

Once clean and sealed in a bag, you can store your mattress flat on the floor or prop it against the wall at an almost flush angle. Do not store it against the wall at an acute angle, or else the support layers will be under extreme stress.

Note: if you wet clean your mattress, let it dry thoroughly before wrapping it. 

Storing a new (unboxed) mattress

If your mattress is new but unboxed, you can leave it in its plastic packaging or slip it into a mattress storage bag without cleaning it.

New mattresses must be stored according to the manufacturer’s instructions. Otherwise, you can damage them and void the warranty. Most new mattresses need storing flat, but some can be propped upright if they have sturdy construction.

If your mattress starts to sag or flop against the wall, it must be stored flat to prevent damage to the internal layers

Storing a new boxed mattress

If you have a mattress-in-a-box, storing it is easy – just put the box somewhere!

Mattresses-in-a-box can stay compressed for years, so there is no risk of leaving your mattress in its box for months before opening it.

If you have removed the mattress from the box, you can put it back, providing you haven’t broken the seal on the mattress’s plastic wrap. Once broken, the mattress expands, and you need to store it like any other mattress (see above).

General tips for mattress storage

  • Beware of the potential for punctures – sharp objects can pierce a mattress and the coverings you use. Screws, nails, hand tools, knives, and even rubbing past the mattress with something blunt can damage it.
  • Beware of dampness – if you don’t store your mattress in an airtight mattress storage bag, damp rooms will destroy your mattress. Avoid basements and damp spaces if you don’t have an airtight covering.
  • Beware of mattress deformation – if you store your mattress on its side, the materials inside could compress and sink. It’s best to store a mattress flat, or you could permanently damage the internal support system. 
  • Now is the time to give it a clean – cleaning your old mattress before storage will ensure there are no bacteria to fester. This is especially important if the mattress is in a humid environment.
  • Is a folding bed an option? If you are storing a guest room mattress, a folding bed takes up around the same space in storage and leaves no bed frame behind. Check out our range of folding beds for ideas.
