Whether you’re moving house, redecorating or simply need to free up some space, knowing how to store a mattress properly can make all the difference to its condition when you come to use it again.
Mattresses are designed to provide years of comfort and support, but incorrect storage can lead to sagging, damp, mould or damage to the fillings. The good news is that a little preparation goes a long way.
From cleaning and wrapping your mattress to choosing the right position for storage, here’s everything you need to know.
How to store a mattress: step by step
1. Clean your mattress before storing it
Before putting your mattress into storage, give it a thorough clean.
Start by removing all bed linen, mattress protectors and toppers, then vacuum both sides of the mattress using an upholstery attachment. Pay particular attention to seams and edges where dust can collect.
If the care instructions allow, spot-clean any marks with a small amount of suitable cleaning solution. Avoid soaking the mattress, as excess moisture can become trapped during storage.
Most importantly, make sure your mattress is completely dry before wrapping it.
2. Protect it with a mattress cover
Once clean and dry, place your mattress inside a breathable mattress storage bag or protective cover.
This helps prevent dust, dirt and moisture from reaching the surface while it is being transported or stored.
Avoid wrapping the mattress too tightly in non-breathable plastic for long periods, particularly if there is any possibility of moisture being trapped inside.
For everyday protection once your mattress is back in use, a mattress protector can also help shield it from spills, dust and general wear.

3. Keep your mattress flat where possible
One of the most important rules when learning how to store a mattress is to keep it in its natural position.
Ideally, mattresses should be stored flat, just as they would sit on a bed base. Leaving a mattress upright or leaning against a wall for an extended period can place unnecessary pressure on its internal structure and may cause the fillings or springs to shift.
Make sure the mattress is supported evenly underneath and avoid resting heavy boxes or furniture on top.
4. Choose a dry, temperature-controlled space
Where you store your mattress matters just as much as how you wrap it.
A clean, dry and well-ventilated room is best. Avoid damp garages, sheds, basements or anywhere subject to large changes in temperature or humidity.
Moisture can encourage mould and mildew, while prolonged exposure to excessive heat or cold may affect some mattress materials.
If you’re using a professional mattress storage facility, look for a clean, secure and preferably climate-controlled unit.
How to transport a mattress safely
If you’re moving your mattress before putting it into storage, protect it from dirt and damage during the journey.
Wrap it securely in a mattress bag and make sure it is supported when moving it through doorways or downstairs. Larger mattresses are generally easier and safer to move with two people.
Try not to fold or bend the mattress unless the manufacturer specifically says it can be. This is particularly important for pocket sprung mattresses, as excessive bending can damage the internal spring system.
During transport, secure the mattress so it cannot slide around or become crushed beneath other belongings.
Can you store a mattress on its side?
For very short periods, you may have little choice but to position a mattress on its side. However, for longer-term storage, laying it flat is usually preferable.
Keeping a mattress upright for several weeks or months can allow internal materials to shift and may affect its shape or support.
If space is limited, check the care guidance for your particular mattress before deciding how to position it.

How long can you keep a mattress in storage?
There isn’t one set limit, provided the mattress has been prepared and stored correctly.
For longer periods of storage, it’s worth checking the mattress occasionally. Make sure the cover remains intact and look for any signs of damp or condensation.
If possible, briefly allow the mattress to air before wrapping it again.
What should you avoid when storing a mattress?
A few common mistakes can quickly damage an otherwise perfectly good mattress:
-
Storing it before it is completely dry
-
Leaving it uncovered
-
Keeping it somewhere damp or poorly ventilated
-
Placing heavy items on top of it
-
Folding or sharply bending it
-
Leaving it standing upright for long periods
Taking the time to store your mattress correctly will help preserve its shape, fillings and supportive feel.
What to do when you take your mattress out of storage
Once you’re ready to use your mattress again, remove its protective cover and inspect it before making the bed.
Vacuum the surface if needed and allow the mattress to air in a well-ventilated room for a few hours.
Once it has had time to breathe, place it onto a suitable bed base and add a clean mattress protector before making your bed.
Keep your mattress protected for longer
Correct storage can help extend the life of your mattress, but everyday care is just as important.
Using a good-quality mattress protector, keeping your bedroom ventilated and following the recommended mattress care instructions can all help your mattress stay fresh and comfortable for longer.
