A mattress is one of those things you don’t think much about until it’s time to move or clear some space. Suddenly, the question pops up: how do you store it without damage? Storing a mattress isn’t as simple as sliding it into a corner, it’s bulky, moisture-sensitive, and easily damaged.
Experts note that extreme heat or cold can damage a mattress by weakening foam layers or warping springs. That’s why it’s best to keep storage temperatures steady, ideally between 65 and 75°F. So, that’s where a climate-controlled storage unit helps, shielding your mattress from humidity swings and unpredictable weather changes.
In this guide, we’ll walk through simple steps on how to store a mattress, from prepping and wrapping to choosing the right storage unit, so your mattress stays comfortable and ready for its next use.
Why It Matters, and What Goes Wrong If You Skip the Basics?
A mattress is bulky, expensive, and oddly sentimental. Store it sloppily, and you risk mildew, lingering smells, or dips that never bounce back. In other words, a mattress that’s treated carelessly can stop feeling like a mattress you want to sleep on. That is why knowing how to store a mattress carefully is worth the extra five minutes up front.
Preparing The Mattress for Storage
Start with a quick inspection, because little repairs now save headaches later. Vacuum surface dust, spot and clean stains with gentle cleaners, and let the mattress dry completely in the sun or a well-ventilated room. It seems obvious, but moisture trapped under a cover is the main culprit behind mold.
Next, wrap it. Use a breathable mattress bag if possible, or a thick, clean mattress cover. For longer storage, a sealed plastic wrap can protect against pests and water; however, make sure the mattress is fully dry first. That step is essential when you’re learning how to wrap a mattress for storage, which helps prevent moisture damage and keeps pests away.
Before you move it, measure the mattress and the path through your home, stairs, and elevator. A little planning avoids bruised corners and bent frames.
Flat Or Upright, Which Is Better?
You might ask, Should I store a mattress flat or upright? The simplest answer is flat, especially for long-term storage. Laying it flat preserves the internal structure and avoids stress spots. So, on the other hand, storing it upright can save space for a short period, but it increases the chance of sagging if it leans for months.
If you must store it upright, keep it supported and don’t lean anything heavy against it. Also, rotate it occasionally to make sure pressure points do not become permanent, as this is an important part of learning how to store a mattress the right way.
Why Climate Matters in Detroit, And the Better Option?
Detroit weather swings a lot, with moisture often being the villain. That is why the benefits of climate-controlled self-storage units are worth mentioning; they cut down on humidity changes and temperature extremes that can ruin foam or encourage mold. Plus, if you plan to store a mattress for several months, choosing climate control is the safer bet, particularly during humid summers or cold winters.
Picking The Right Unit Size, Quick Guide
Size matters, and not just for the mattress. You want space to move around the mattress when you set it down. Use our storage unit size guide to match mattress type and extras.
- A 5×5 Storage Unit is about the size of a small closet, useful for a twin mattress or a couple of boxes. It may work if you only have a mattress and little else.
- A 5×10 Storage Unit fits a full or queen plus a few boxes, making it a common choice for someone storing a mattress and bedroom items. See our 5×10 details for examples.
- A 10×10 Storage Unit gives room for a queen or king mattress and furniture, so it’s useful for longer moves or whole-room storage.
It’s common to ask questions like how much does a 5×10 storage unit cost per month or even how much does a 10×10 storage unit cost per month if you’re planning for a bigger move. Others might only need to know how much does a 5×5 storage unit cost per month, especially when storing something smaller like a twin mattress. Notably, prices shift depending on factors such as location, seasonal demand, and whether you choose climate control.

Storing A Mattress in A Storage Unit: Practical Tips
When you bring the mattress to the unit, follow a few habits that pay off:
- Elevate it off the floor, use pallets or shelving to avoid ground moisture and pest access.
- Keep the mattress covered, and if your unit is not climate-controlled, add a breathable layer to reduce condensation.
- Avoid stacking heavy items on top. Pillows are fine, dressers are not.
- Label the cover with the date and orientation, especially for memory foam, so you can rotate or flip if needed.

Safety Tips for Storing Your Mattress
When learning how to store a mattress, a few safety steps can make the difference between lasting comfort and lasting damage:
- Elevate off the floor to prevent moisture absorption.
- Avoid heavy stacking, which can deform springs and foam.
- Check occasionally, especially for long-term storage, to spot issues early.
A little care ensures your mattress stays clean, supported, and ready when you need it.
Short-Term Vs Long-Term Storage, Different Mindsets
For short-term storage under a month, wrapping and upright storage might be fine. For long-term, plan to use climate control, store flat, and visit the unit once or twice to check for any problems. Therefore, we noticed customers who check in occasionally avoid surprises, and that habit is calming.
