How to Protect a Mattress in Storage?

Whether you’re moving home, decluttering, or storing furniture during a renovation, your mattress is one of the most important items you’ll need to protect. A quality mattress represents a significant investment, and without proper care during storage, it can suffer from moisture damage, mould, dust mites, and structural deterioration.
The good news is that with the right preparation and storage methods, you can keep your mattress in pristine condition for months or even years. Below, we will walk you through everything you need to know about protecting your mattress whilst in home storage, ensuring it remains clean, dry and ready to use when you need it again.
Why is protecting your mattress in storage so important?
Mattresses are particularly vulnerable in storage environments for several reasons. Unlike other furniture items, they’re designed to be breathable and absorbent, which means they can easily soak up moisture from the air. This moisture creates the perfect breeding ground for mould and mildew, which not only damages the mattress but can also pose serious health risks.
Additionally, mattresses provide an ideal habitat for dust mites and other pests if left unprotected. The materials inside your mattress (whether memory foam, springs, or natural fibres) can also become compressed or damaged if stored incorrectly, affecting the comfort and support they provide. By taking proper precautions, you’ll protect your investment and ensure you have a hygienic, comfortable mattress to return to.
How should you clean your mattress before storage?
Before storing your mattress, it’s essential to give it a thorough clean:
- Start by stripping off all bedding and vacuuming the entire surface of the mattress, paying particular attention to seams and crevices where dust and debris accumulate.
- Use the upholstery attachment on your vacuum cleaner to ensure you’re not damaging the fabric. If there are any stains, treat them with an appropriate cleaner – for most mattresses, a mixture of mild detergent and water works well, but always check the manufacturer’s guidelines first.
- After spot-cleaning, it’s crucial to allow your mattress to dry completely. This might take 24 to 48 hours in a well-ventilated area. Never store a damp mattress, as this will almost certainly lead to mould growth.
- Once it’s completely dry, you can proceed with wrapping and storing it.
What type of mattress cover should you use?
Choosing the right cover for your mattress is perhaps the most important step in the protection process. You’ll want to invest in a purpose-designed mattress storage bag or cover. These specialist covers are typically made from thick, breathable plastic that protects against dust, dirt, and pests whilst still allowing air circulation to prevent moisture build-up. Standard mattress protectors or fitted sheets aren’t sufficient for long-term storage, as they don’t provide adequate coverage or protection.
When selecting a mattress cover, ensure it’s the correct size for your mattress. The cover should fit snugly without being too tight, and it should completely enclose the mattress with a secure closure – usually a zip or adhesive strip. Some people make the mistake of using non-breathable plastic sheeting, such as standard polythene, which can trap moisture inside and cause condensation. Breathable storage bags are designed specifically to prevent this problem whilst keeping your mattress clean and protected.
Should you store a mattress flat or upright?
The way you position your mattress in storage can significantly impact its condition. Ideally, mattresses should be stored flat in their natural position. This prevents sagging and maintains the structural integrity of the internal components, whether that’s springs, foam, or other materials. However, we understand that space constraints sometimes make flat storage impractical.
If you must store your mattress upright or on its side, make sure it’s properly supported and not leaning at an angle, which could cause permanent warping. Never store anything heavy on top of a mattress, as this can compress the materials and create permanent indentations. If you’re storing your mattress flat and need to stack items, place the mattress on top of other furniture rather than underneath it. This simple adjustment can prevent damage and keep your mattress in excellent condition.
How can you prevent moisture damage during storage?
Moisture is the enemy of stored mattresses. Even in seemingly dry environments, humidity can accumulate and lead to mould, mildew, and unpleasant odours. The key to preventing moisture damage is choosing the right storage environment. Your mattress should be stored in a clean, dry space with good air circulation and stable temperatures.
Self storage units specifically designed for household items are ideal because they’re typically kept at optimal humidity levels. Avoid storing mattresses in damp basements, unheated garages, or outdoor sheds where temperature and humidity fluctuate dramatically. If you’re storing your mattress at home, choose an upstairs room or closet rather than a basement. You might also consider using moisture-absorbing products like silica gel packets placed near (but not directly on) your mattress to help control humidity levels.
What about protecting against pests and dust?
Beyond moisture, pests and dust pose significant threats to stored mattresses. Dust mites, bed bugs, and other insects can infiltrate an unprotected mattress, making it unusable when you retrieve it from storage. Your breathable mattress cover provides the first line of defence, but there are additional steps you can take.
Before wrapping your mattress, consider applying a fabric-safe pest deterrent spray, though make sure it’s completely dry before covering. Throughout the storage period, if you have access to your mattress, it’s worth inspecting it every few months to check for any signs of pest activity or dust accumulation. This proactive approach means you can address any issues before they become serious problems.
