What are the common questions about storing a mattress?

What’s the best way to protect a mattress during storage from dust and pests?

The best way to protect a mattress during storage is to completely encase it in a mattress storage bag specifically designed for this purpose. This bag should be made of durable, breathable material, such as plastic or canvas, and should be sealed tightly with packing tape after the mattress is inside. Adding desiccant packets inside the bag can further protect against moisture, and storing the mattress in a clean, dry environment will also help prevent dust and pest infestations.

Proper encasement is crucial because it creates a physical barrier against dust mites, bed bugs, rodents, and other pests that can damage or contaminate the mattress. A breathable material prevents moisture buildup inside the bag, which could lead to mold or mildew growth. Avoid using regular plastic sheeting, as it doesn’t allow air circulation and can trap moisture. Sealing the bag securely prevents pests from entering through any openings. Furthermore, before encasing the mattress, thoroughly clean and dry it. Vacuum the entire surface of the mattress to remove dust, dirt, and potential allergens. If there are any stains, spot clean them with a mild detergent and water, ensuring the mattress is completely dry before placing it in the storage bag. Standing the mattress on its side during storage can also help prevent sagging and maintain its shape, but be sure the storage area is clean and dry to avoid the bottom edge absorbing moisture.

Can I store a mattress on its side, or should it always be flat?

While storing a mattress flat is generally preferred, storing it on its side is acceptable for shorter periods. However, prolonged upright storage can lead to sagging, uneven settling of the internal components, and potential damage to the mattress’s structure, especially in innerspring or hybrid models.

Storing a mattress flat distributes its weight evenly, preventing the internal materials from shifting or compressing in one area. When a mattress is placed on its side, the weight is concentrated along the edge in contact with the floor, which can cause the coils, foam layers, or other components to become misshapen over time. This is particularly true for heavier mattresses. If you must store your mattress on its side, rotate it periodically to distribute the weight more evenly. Consider the mattress type too; all-foam mattresses are generally more resilient to being stored on their side compared to innerspring mattresses with their more complex internal structure. Ultimately, the best way to store a mattress is flat, on a supportive surface like a bed frame or the floor (covered with a protective layer). This minimizes the risk of damage and helps maintain the mattress’s shape and comfort. If you only have the option of storing it on its side, minimize the storage duration and take precautions, such as rotating the mattress, to prevent long-term damage. Always use a mattress storage bag to protect it from dust, moisture, and pests regardless of the storage orientation.

How long can a mattress be stored before it starts to degrade?

A mattress can be stored for approximately 6 to 12 months without significant degradation, provided it’s stored properly. Beyond a year, the risk of dust mite infestation, mold growth (especially in humid environments), and material breakdown increases considerably, even with careful storage.

The key to preserving a mattress during storage lies in controlling its environment and protecting it from external factors. Factors such as temperature fluctuations, humidity, and direct sunlight can accelerate the breakdown of foams and fabrics. A mattress stored in a damp basement is far more likely to develop mold and mildew than one stored in a climate-controlled storage unit. Similarly, exposure to direct sunlight can fade colors and weaken the structural integrity of some materials. To maximize your mattress’s lifespan during storage, preparation is crucial. Clean the mattress thoroughly before storing it to remove dust, allergens, and potential food particles that could attract pests. Enclose it in a breathable, waterproof mattress bag to protect it from moisture and dust. Store it flat, if possible, to prevent sagging or distortion of the coils or foam. Regularly check on the mattress during extended storage to ensure the protective bag remains intact and there are no signs of moisture or pests.

What type of covering or bag should I use for long-term mattress storage?

For long-term mattress storage, invest in a high-quality, breathable, and waterproof mattress storage bag specifically designed for this purpose. These bags protect against dust, moisture, pests, and other potential damage while allowing for some air circulation to prevent mildew growth.

The key considerations are breathability and waterproofing. Plastic tarps, while waterproof, trap moisture and can lead to mold and mildew, effectively ruining your mattress. A breathable bag, often made of heavy-duty polyethylene or a similar material with ventilation holes, allows air to circulate, preventing moisture buildup. Waterproofing is crucial to protect against spills, leaks, and humidity, especially in environments prone to dampness like garages or basements. Ensure the bag is appropriately sized for your mattress; an oversized bag can leave excess material vulnerable to tearing or snagging, while an undersized bag simply won’t work. Look for bags with durable zippers and reinforced seams to prevent tearing during handling. Before inserting your mattress, thoroughly clean and dry it. Consider adding baking soda to the mattress surface to absorb any residual moisture, vacuuming it off before sealing the bag. Sealing the bag properly is paramount to maintaining a clean and protected environment for your mattress during storage. You may also add mothballs or cedar chips inside the sealed bag as a pest deterrent, especially if storing in an area prone to insect activity.

How does temperature and humidity affect a stored mattress?

Temperature and humidity are critical factors in mattress storage because they directly influence the growth of mold, mildew, and the degradation of mattress materials. High humidity promotes moisture absorption, creating an ideal environment for mold and mildew, which can permanently damage the mattress and pose health risks. Extreme temperatures, both hot and cold, can also degrade foam and other materials, leading to premature wear and tear.

Prolonged exposure to high humidity allows moisture to seep into the mattress fibers, creating a breeding ground for mold and mildew. These organisms not only cause unpleasant odors and staining but can also trigger allergic reactions and respiratory problems. Once established, mold and mildew are difficult, if not impossible, to completely remove, rendering the mattress unusable. Therefore, storing a mattress in a damp basement, garage, or storage unit without climate control is highly risky. Similarly, extreme temperatures can negatively impact the mattress’s structural integrity. Intense heat can cause foam layers to break down and lose their shape and support. Cold temperatures, especially when fluctuating, can make the materials brittle and prone to cracking. Ideally, a mattress should be stored in a cool, dry, and well-ventilated area to prevent these issues. Using a mattress protector or encasement can also help shield it from environmental damage during storage. While not always possible, climate-controlled storage units are the best option. If that is not within budget, focus on these steps:

  • Thoroughly clean and dry the mattress before storing it.
  • Use a breathable mattress bag for protection.
  • Store it in a cool, dry place with good ventilation.
  • Avoid direct sunlight and extreme temperature fluctuations.

How often should I rotate or flip a mattress that is in storage?

You should rotate or flip a mattress in storage every 2-3 months. This helps prevent the settling of materials and ensures even weight distribution, ultimately preserving the mattress’s comfort and lifespan.

Rotating or flipping a mattress, even when it’s not in use, is crucial for maintaining its structural integrity. Mattresses are made of various materials like foam, coils, and fibers, all of which can compress over time due to gravity. When a mattress sits in the same position for an extended period, the lower layers can become overly compressed, leading to uneven support and potential sagging. By rotating or flipping it, you distribute the pressure more evenly across the entire surface. Consider the type of mattress you have. If it’s a single-sided mattress (designed to only be used on one side), you should only rotate it. Double-sided mattresses can be both rotated and flipped. Regardless of the type, consistent rotation/flipping is especially important during storage because the mattress isn’t being actively used and adjusted to by a sleeper’s movements. If you are storing your mattress, it is also wise to consider using the following guidelines for long-term storage success:

  • Clean the mattress thoroughly before storing it.
  • Wrap it in a breathable mattress bag.
  • Store it flat in a climate-controlled environment.

What are the storage requirements for different mattress types (foam, innerspring, etc.)?

Storing a mattress properly, regardless of type (foam, innerspring, hybrid, etc.), requires a clean, dry, and climate-controlled environment to prevent mold, mildew, and damage to the materials. Proper preparation, including cleaning and wrapping the mattress, is crucial, and storing it flat is generally recommended, although some exceptions exist for certain foam mattresses.

Different mattress types have slightly varying needs during storage. Innerspring mattresses are generally more robust and less susceptible to damage from being stored on their side for shorter periods, but the coils can still be bent or compressed unevenly over extended storage. Foam mattresses, especially memory foam, are more susceptible to compression and deformation if stored improperly. They should ideally be stored flat to maintain their shape and integrity. Hybrid mattresses, combining innerspring and foam layers, require similar care to innerspring mattresses, emphasizing flat storage to prevent uneven wear on the coil system and foam layers. Avoid extreme temperatures and humidity, as these can degrade the materials in all mattress types, leading to faster breakdown and potential mold growth. Here’s a helpful way to think about the priorities when storing a mattress:

  • Cleanliness: Vacuum and spot-clean the mattress before storing to prevent attracting pests and mold growth.
  • Protection: Wrap the mattress in a breathable, waterproof mattress bag to shield it from dust, moisture, and pests.
  • Environment: Store the mattress in a cool, dry, and climate-controlled environment. Avoid attics, garages, or basements with high humidity or temperature fluctuations.
  • Orientation: Store the mattress flat whenever possible, especially for foam and hybrid mattresses. If storing on its side is unavoidable, rotate it regularly to distribute the weight and prevent permanent deformation.

And that’s all there is to it! Storing a mattress properly might seem like a chore, but it’s totally worth it to keep your investment clean and comfy for whenever you need it again.
