The Importance of a Proper Mattress Storage
Now, you can certainly just leave your mattress lying around, but storing it properly will benefit everyone. Here’s how:
- Long-term mattress storage decreases the chances of funky odors. Storing a mattress in a specifically designed place prevents it from soaking the odors from your home or insufficient air circulation between the layers, which also can result in a stale odor.
- No mold or mildew will get inside your mattress. Proper humidity is as important as proper aeration, and if your mattress is just lying on the basement floor or elsewhere, it becomes an easy target for colonies of mold or mildew that thrive easily in humid environments and can ruin your mattress.
- Your mattress will retain its shape. By properly storing a mattress, you protect it from any possible impact that can damage the construction. This is especially true for the firm and ultra-firm mattresses that typically have fewer layers, and hence, are more susceptible to the outside impact.
Places Where You Should (and Shouldn’t) Store a Mattress
So, now you know all the benefits of storing a mattress in the right way.
It is time to choose the place for it, because even a twin mattress designed for lightweight people check more info here) is pretty bulky, not to mention bigger sizes.
Below, you will find a couple of ideas on where to put your mattress, as well as a list of less appropriate places for storage.
Let’s start with the safe places for long-term mattress storage:
- Climate-controlled storage unit. This is obviously your best bet. A storage unit with a climate control system will help you take a hold of temperature, humidity, and aeration, which will be useful not only for mattress storage but for literally everything you may want to put inside a unit.
- Dry ventilated room. If you cannot afford a storage unit, you can organize space in your home to fit your needs. For mattress storage, it’s better to choose a room that isn’t damp and has some air circulation, either via the vents or through the windows.
Also, make sure that your mattress doesn’t touch the floor directly. Keep it wrapped in something or slightly elevated above the floor — you can use pellets or a plywood sheet for that matter. Elevating the mattress will promote air circulation under its bottom and prevent the mildew from growing.
Now, here are the places where you definitely shouldn’t store your mattress:
- Basement, garage, or any room beyond ground level. These spaces usually have high humidity and may create a good environment for bacteria and fungi, which will end up inside your mattress. If you plan to use it further, be sure to choose a more suitable storage place.
- Near the heat source. It doesn’t matter whether your mattress is composed of natural latex or synthetic memory foam: both of these materials cannot withstand high heat. They will melt or deform, thus making your bed uneven and uncomfortable.
- Near the sharp objects. Sharp objects can poke through the mattress fabric and protective layers and damage the insides. Also, mildew, dust mites, or even bed bugs will have a much easier time getting inside your mattress if there’s a hole in it.
How to Prepare the Mattress for Storage?
Finally, let’s run through a list of things you need to do right before you place your mattress into a storage vault or a dark room.
Clean The Mattress
Your mattress has probably collected some dust and debris during use, and the dust buildup, along with insufficient cleaning, creates a perfect environment for the dust mites (1), which are the most common allergens in U.S. homes.
To prevent them from hosting a party inside your mattress, give it a thorough cleaning session before you put it into storage:
- Remove all the bedding and mattress protectors from a mattress and vacuum it from all sides. If your mattress has a tufted top, use a small brush for hard-to-reach places to clean every crevice.
- If your mattress has some stains, treat them. Make a mixture of lukewarm water, dish soap, and baking soda and pour it into a spray bottle. Generously spray the mixture on a stained area and a few inches around it. Let sit for 10-15 minutes and blot the stain with a cloth. Allow the mattress to dry before hauling it away.
- Disinfect the surface. To make sure that your mattress has a minimal amount of microorganisms, you can disinfect the surface by spraying it with a Lysol spray and allowing it to dry out.
Invest in a Mattress Storage Bag
You should store your mattress in a wrapped state to prevent any unwanted critters from using it as their home.
The easiest way to do it is to use perforated plastic wrap, but if you’re about to get fancy, we recommend that you purchase a mattress storage bag. It has a layered design with a waterproof lining, and can securely seal your mattress inside and protect it from any unpleasant accidents.
Oh, and don’t worry:
You can easily find storage bad for your California King mattress because they’re available in almost all online stores.
Store a Mattress on a Flat Surface
Mattresses have a structure: they consist of top, comfort layers, transitional layers, and base. And the best way to maintain your structure, and therefore the comfort of your mattress is by laying it on the floor or another flat surface.
Placing a mattress on the side, folding, or rolling it may cause the structural elements to shift or bend under their weight, which will result in lumps or broken coils. That’s why your storage room should have enough space to place your mattress as you’d typically put it on the bed.
How to Store a Mattress Depending on Its Type
Generally speaking, the way you store your mattress is the same regardless of its type: don’t place it on an uneven surface or right on the ground, and make sure it’s protected from mold and dust mites.
However, each mattress type has its unique features, which might prompt you to the way of arranging the best storage space for it:
- Memory foam mattress. Memory foam mattresses don’t have coils inside and can adjust to your body curves pretty easily. However, the softness of memory foam can work against you if you place a mattress on an uneven surface. Plus, memory foam is especially susceptible to mildew growth, so be sure to wrap the mattress into a plastic or place it in a storage bag.
- Latex mattress. Natural latex is dense and heavy, so it has a higher chance to bend under its weight. Place a latex mattress on a flat supportive surface and don’t store it on the side or in an upright position.
- Hybrid mattress. Hybrid mattresses are among the heaviest, and they also have a rigid coil layer for a core. However, the coils inside a hybrid mattress typically are individually wrapped, which means they are more likely to shift if you place a mattress on its side.
- Spring mattress. Unlike hybrid mattresses, spring mattresses have a reinforced coil unit with a wired perimeter, which maintains shape better, But they are still prone to bending and breaking through the mattress, so be sure to store it in a flat position.
- Futon Mattress. Futon mattresses should be dried and stored in plastic before storage, ensuring it’s folded along its bi-seam or tri-seam, depending on what type of futon mattress you have. To help the cotton filling inside stay lofty, avoid placing heavy objects on top of the futon during storage.
How to Store Big Mattresses?
For big sizes, such as King, California King or bulky RV mattresses (check the best ones on this page), as well as all high-profile mattresses, the main concern is their weight. If you place these mattresses on a lumpy surface or decide to store them on the side, they might crook and bend under their weight and lose all supportive properties.
So, the best you can do to properly store your King-sized mattress is to place it flat and ensure no things are lying on it, so the top layers won’t get deformed.
Can you store a mattress in an upright position?
It’s better not to store the mattress in an upright position or on its side, even though some manufacturers suggest that. The chances of bending or crooking in these positions are much higher than if your mattress would simply lie on the floor.
How to prevent bed bugs while the mattress is in the storage unit?
Purchase a mattress protector with hidden zippers that encases the mattress from all sides. Beg bugs cannot chew into dense fabrics and plastic lining, so your mattress will be safe. When you bring it back home, replace the mattress protector with a new one, and you’re all set.
Can you fold a mattress for storage?
No, both because it’s very hard to do and because it will damage the mattress.
Can you Store a Tempurpedic Mattress on its Side?
A Tempurpedic mattress should never be placed on its side or should be placed there for the lowest amount of time possible. Tempurpedic mattresses are made up of viscous memory foam that, when shifted on its side, settles towards the bottom, which sometimes cannot be restored.
How do I Store a Mattress Against a Wall?
To store a mattress against the wall, wrap it in a mattress bag after ensuring the mattress is clean and moisture-free, and then lean its base first against the wall. Standing a mattress against the wall can save on space, but may also lead to the mattress losing shape due to the inner core dealing with uneven pressure, causing the integrity to slowly deteriorate. To avoid this, only have your mattress standing upright for a short period of time.
As you can see, storing a mattress is pretty easy! Just wrap it in a dense plastic or put inside a waterproof mattress encasement, and place it in a cool dry place for as long as you need.
Some mattress types may need a bit of a different approach, but having read this article, you will know how to make the most of it and prolong the lifespan of your bed.

Thank you for the informative article on storing a mattress. We are getting ready to do some renovation and construction I need to store several mattresses. Do you have advice for storing five mattresses together? Well they each need to be if something in between them if we were to lay them flat on top of each other? What are those recommendations? Thank you, Amy
You can stack your mattresses on top of each other, but make sure you put the bottom mattress on a box spring or a large sheet of plastic (cardboard should suffice too). Now, you don’t necessarily have to add layers between the mattresses. That being said, since you are planning to do some renovations, chances are some dust can get on your mattresses (if you will store them at home). So, it might be a good idea to wrap each of them in plastic to protect your mattresses from dust and other debris.
I moved in a new apartment two weeks ago ( I’m based in Dublin). When I signed the rent contract with the Agency ( they work in behalf of landlord), they guarantted to me that I could bring my own personal mattress and they would arrange to remove the one in this apartment. Today I received bad news from them: they could not dispose for the one in my apartment and I could leave it underneath or something like that.
Not sure what do they mean for “leaving it underneath”. The mattress is a big size and at the moment is against the wall in my living room. Any suggestion?
As far as I understand, the rent agency representatives suggested you keep the old mattress underneath your new one (kind of like a box spring), which isn’t a good idea, in my opinion.
If you don’t reach a compromise with them, you will probably have to hire a professional mattress removal service. As far as I know, it costs around 30-60 Euros in Dublin.
I am planning to store 2 king size mattress and box springs in a climate controlled storage unit for about 1 year. When stacking, should I start with box springs, then first mattress and then the 2nd box spring and 2nd mattress on top of that?
The best way I’ve found to store king-sized mattresses is to start with the box spring, and then place the mattress on top. Due to the delicate nature of mattresses, I would recommend not placing anything heavy on top of the mattress, as this can cause the foam and coils inside to become damaged over time.
I have the same question as Cindy from October 31, 2022 but with Queen size beds?
Thank you for your question! For queen-sized beds, I’ve found the best way to store them is by starting with the box spring and then placing the mattress on top. As coils and foam can become damaged over time with heavy weight on top of the mattress, I would recommend avoiding placing another box spring and mattress on top of them.
We are moving to a new home, we have two new king size mattresses, but we will not have two bedrooms. While we know it is not recommended, we will need to store one of the mattresses standing up rather than lying flat down because we do not have the storage space. We do not want to throw it out since it is brand new, so we are willing to take a chance doing this.
What would you recommend as far as supporting this standing up? Again, we know there is no guarantee and that it is not recommended, but we need to take the chance.
Thank you for any suggestions you can offer.
Thanks for reaching out! I understand that sometimes storage space might not allow a mattress to lie flat, and I still stand by seeing if you can lie it flat on the floor or create a loft in the storage area so the mattress can rest overtop of other storage items. My only other recommendation would be to store it on its side for as short as possible, as gravity will cause the innerspring or memory foam core to come out of balance, making the mattress uncomfortable to sleep on.
