How To Store A Mattress In A Storage Unit | Expert Guide

Store A Mattress

A quality mattress is an investment for your health, and can withstand up to 10 years of use when properly maintained.3 If you’re moving house, renovating, travelling, or doing anything else that requires putting your stuff into storage, it’s important to store your mattress properly to keep it in good condition.

In this article, we’ll provide comprehensive instructions on how to store a mattress in a storage unit, to keep it dry, and in great shape.       

What will I need to store my mattress?

Before packing your mattress into a storage unit you’ll need to grab some supplies. Make sure you have a vacuum, upholstery cleaner, packing tape, a plastic mattress cover, and some old sheets. You’ll also need a van to transport it.

Once you’ve gathered these necessities, you can get started. 

1. Clean and vacuum your mattress before storing

It’s important that you clean your mattress before it goes into storage. This is to keep any nasty pests, odours or allergens away from the sides, tops and seams of the mattress. Before you start cleaning, strip the mattress of its sheets, and remove the mattress from the bed frame. Then you can thoroughly vacuum both sides of the mattress, paying close attention to the seams. Finally, you can apply the upholstery cleaner as per the instructions on the label.

If your mattress has an unpleasant odor, you can sprinkle the offending areas with baking soda and let it sit for 24 hours, before vacuuming it up.

When you’ve finished cleaning, you’ll need to let your mattress dry for up to two hours before moving onto the next step.

2. Wrap the mattress in a protective plastic cover

To protect the mattress from moisture, mould, staining, and dirt while it’s being transported to the storage facility, you’ll want to use a plastic cover. Alternatively you can also wrap the mattress in plastic and secure it with packing tape for a tight seal. Choosing a light, breathable plastic material will allow your mattress to stay covered for longer periods of time before reaching the storage unit.

3. Move the mattress to a secure storage unit

The best place to store your mattress is in a climate-controlled storage unit, as it’ll help to keep the mattress cool in summer, warm in winter, as well as free of humidity, to discourage the growth of mould. A climate-controlled unit will keep your mattress safe from any significant damage caused by extreme temperature changes.

While moving your mattress to a secure storage unit, you’ll want to protect it from rain, hail, and sunlight, and for this reason, it’s best to use a van for the trip. The best way to move the mattress is to position it on its side in the van, which will prevent the mattress from bending, and from heavy furniture being piled on top of it. During the trip, you can safely rely on your plastic mattress storage bag to protect your mattress from any potential damage.

4. Wrap the mattress in old sheets

When you arrive at your secure storage unit with the mattress, switch its plastic storage bag for old sheets. Sheets will let the mattress material breath and avoid any build up of condensation or mildew. This type of mattress cover will also continue to protect your mattress from dirt or significant distress.

When wrapping your mattress, try to get 1-2 large sheets instead of several smaller ones. This will allow you to fold your sheet all the way around the mattress, and tuck in any excess fabric. Finally, use extra layers of fabric along the corners and outer edges of your mattress to prevent any damage while in storage.

5. Lay the mattress flat in storage

While it’s okay to position the mattress on its side in a moving vehicle, one of the best mattress storage solutions is to lay the mattress flat. This will allow you to maintain the natural position of your mattress, and help to prevent foam, padding and coils from drooping. Storing a mattress on its side will skew the coils, and slowly destroy the padding inside.

6. Avoid stacking your mattress while in storage

Can you stack mattresses for storage? Unfortunately not. Placing weight onto your mattress in storage adds pressure that prevents the material from resting. Over time, the mattress will flatten under the added weight, which will shorten its lifespan. It’s possible to stack the mattress on top of other furniture, but you’ll need to make sure the furniture is stable, and that there’s no bits poking into the mattress that will create permanent impressions. 

We understand that this is frustrating because self-storage is charged by the size of the unit, and a flat mattress takes up a lot of space. But if you want to keep your mattress in good condition, you should avoid stacking items on top of it.
