Quick Answer
A mattress can potentially get ruined in a storage unit due to moisture, pests, and compression. To help prevent damage, use a waterproof mattress cover, elevate the mattress off the floor, regularly inspect for pests, and rotate the mattress. With proper precautions, it’s possible to store a mattress for extended periods in a storage unit without ruin.
Overview
Storing a mattress in a storage unit for any length of time does put it at risk for potential damage. However, there are steps you can take to minimize the chances of ruining your mattress while it’s in storage:
- Use a waterproof mattress cover – This will protect against moisture damage from leaks or flooding.
- Elevate the mattress – Place it on wood pallets or a platform to prevent contact with the concrete floor.
- Inspect for pests – Check regularly for signs of mice, bugs, or molds.
- Rotate periodically – Turn the mattress over every few months to prevent compression issues.
- Clean before storing – Vacuum and sanitize the mattress before storage to remove allergens.
- Store in climate control – If available, choose a climate-controlled unit to help regulate temperature and humidity.
With the right safeguards, there’s no reason a quality mattress shouldn’t be able to withstand months or even years in a storage unit without being ruined. Continue reading for more detailed information on protecting your mattress during storage.
Moisture and Mold
Excess moisture is one of the biggest threats to a mattress in storage. Storage units often have concrete floors, which means any water that gets in can pool around and soak into the mattress. High humidity can also lead to mold growth.
To protect against moisture damage:
- Use a waterproof mattress cover – Choose a high-quality encasement made of vinyl or polyethylene to create a waterproof barrier around the entire mattress.
- Elevate off the floor – Place the mattress on pallets or a platform so it’s not directly on the concrete floor. You want several inches of clearance underneath.
- Inspect for leaks – Check for any water intrusion after heavy rains or floods. Look for moisture on the floor near the mattress.
- Consider climate control – This will regulate humidity levels and condensation.
- Air out periodically – Rotate and flip the mattress to allow ventilation if stored long term.
With proper moisture prevention, mold should not be an issue. But inspect periodically for any fuzzy or discolored spots that could indicate mold. Address any moisture problems immediately.
Pests and Bugs
Rodents like mice and rats, as well as bugs like carpet beetles and bed bugs, can take up residence in a mattress while it’s in storage. This can obviously cause extensive damage and make the mattress unsanitary.
To deter pests:
- Vacuum thoroughly – Remove all debris, dander and crumbs that could attract pests before storage.
- Use mattress protectors – Encasements create a barrier that makes it harder for bugs to get in.
- Elevate the mattress – This reduces access for rodents gnawing from underneath.
- Use pest control traps – Place traps around the unit to catch any pests that get in.
- Inspect regularly – Check closely for droppings, chew marks, bugs, and other signs of infestation.
- Treat any issues – If pests are found, use appropriate sprays or fumigation to remove them.
With vigilance and preventative steps, pest damage can be avoided. But you’ll need to monitor closely, especially in the first few weeks after initial storage.
Compression
Mattresses use flexible foams and spring systems that can compress and sag when left under pressure for too long. Laying flat and stationary for months or years can lead to permanent indentations.
To prevent compression problems:
- Rotate periodically – Flip and rotate the mattress every 2-3 months if stored long-term.
- Use a foundation – Place plywood between the mattress and pallets so weight is evenly distributed.
- Stand upright – Try storing the mattress standing on its side rather than flat if space allows.
- Avoid folding – Never tightly roll or fold a mattress for storage as this strains the foam.
With periodic rotation and even support, compression issues should be minimal. But a sagging mattress may need time to re-expand after long-term storage before it feels normal again.
Off-Gassing
Off-gassing refers to the release of volatile organic compounds (VOCs) from mattress foams and adhesives. This chemical smell is most noticeable with brand new mattresses. Storing a mattress may slightly worsen or prolong off-gassing.
To minimize odors:
- Air out before storage – Leave the mattress unboxed in a room for a few days before storage.
- Use an odor cover – Mattress encasements designed for off-gassing can help contain the smell.
- Ventilate periodically – Flip and rotate the mattress to air it out if needed.
- Let air out fully – Before using, keep the mattress in a room for 24-48 hours to let odors dissipate.
Off-gassing odors are generally harmless for most people. But letting a mattress air out properly before and after storage will help minimize this temporary smell.
Preparing Your Mattress for Storage
To maximize your mattress’s chances of surviving storage damage-free, start by taking a few important preparatory steps:
Vacuum Thoroughly
Use a handheld vacuum to remove dust, dander, hair, crumbs, and other debris. This will eliminate anything that could attract pests later on. Get into crevices and under seams. Change out vacuum bags afterwards.
Clean Any Stains
Use an enzymatic cleaner and small amounts of water to gently blot out urine, blood, sweat, or food stains. Let the mattress dry completely before storage.
Sanitize the Mattress
Mist the mattress lightly with a disinfectant spray and allow to fully dry. This will kill mold, bacteria, dust mites, and allergens.
Air Out Off-Gassing
If the mattress is new, keep it unboxed in a well-ventilated room for 1-2 days to allow initial off-gassing before storage.
Protect with Encasements
Cover the mattress in a waterproof, breathable cover or encasement. Zip it closed without bedding inside.
Storing the Mattress in a Storage Unit
Once prepped for storage, carefully transport and place the mattress inside your storage unit. Be sure to take additional protective measures:
Elevate Off the Floor
Use wood pallets, platforms, or shelving to keep the mattress at least a few inches above the concrete floor. This prevents moisture damage and pest access.
Consider Climate Control
A climate-controlled unit will help regulate humidity and prevent condensation that can lead to mold growth.
Place Traps for Pests
Put down sticky traps or bait stations around the perimeter to help catch any rodents or bugs that get inside.
Inspect Regularly
Check on the mattress every 4-6 weeks if possible. Look closely for any signs of mold, pests, or compression issues. Address any problems immediately.
Rotate Periodically
Flip and rotate the mattress every 2-3 months. This helps it retain its shape and prevents sagging.
Protecting Different Types of Mattresses
Specific steps may be needed to prevent damage to certain mattress materials and designs:
Innerspring
– Use a plywood foundation to evenly distribute weight and prevent compression of coils.
– Allow space around coils for ventilation to prevent moisture buildup.
– Flip occasionally, but rotate very gently to avoid straining coils.
Memory Foam
– Stand upright against a wall if possible, as foam is prone to compression when laying flat.
– Use an encasement made for memory foam to prevent off-gassing buildup.
– After storage, unroll carefully – don’t bend or fold. Then allow 2 days to re-expand before use.
Adjustable Bases
– Remove and store power supply/remote separately in a dry area.
– Disconnect base from mattress before storage to allow separate handling.
– Cover electrical components with plastic to prevent moisture damage.
Pillowtop
– Handle gently and store flat to prevent fill material from shifting or bunching up.
– Use plywood between pallets and mattress for even weight distribution.
– Check regularly for compression indentations and rotate to redistribute fill.
Removing from Storage
When it comes time to remove a stored mattress for use, allow for proper airing out:
– Uncover and unroll the mattress carefully. Watch for rips, stains, or signs of pests.
– Stand the mattress upright against a wall if possible. This allows air circulation to dissipate odors.
– Place in a well-ventilated room for 24-48 hours before putting on a bed frame.
– Vacuum again and re-cover with fresh bedding before using.
With the right storage conditions and periodic maintenance, a quality mattress can safely stay in a storage unit for up to a few years without ruin. But take preventative measures against moisture, pests, odors, mold, and compression for optimal results. With some care and caution, you can keep mattresses clean and damage-free during storage.
Conclusion
Storing a mattress in a storage unit introduces risks of moisture damage, mold, pests, odors, and compression. But with proper precautions like waterproof encasements, elevation off the floor, climate control, and regular inspection and rotation, a mattress can remain in good condition for extended periods in storage. Prepare mattresses thoroughly before storage, take steps to protect from damage, and air out properly afterwards. With vigilant preventative measures and care, mattresses can survive storage in a unit without being ruined. Just be sure to take the necessary safeguards.
