Compressing a mattress is an efficient way to reduce its size for storage or transportation. By following the right steps, you can ensure the mattress remains protected and retains its original comfort when unpacked.
To compress a mattress, use a vacuum-sealed bag and a vacuum pump to remove air, roll or fold the mattress, secure it with straps, and store it in a protective bag.
This method helps in moving, storing, or shipping a mattress without compromising its quality.
What Types of Mattresses Can Be Safely Compressed at Home?
Not every mattress is a candidate for DIY compression, so it’s important to know what you’re working with before you break out the vacuum bag.
Generally, the following types of mattresses can be safely compressed at home:
- Memory Foam Mattresses: These are the MVPs of mattress compression. Since they don’t contain springs or rigid frames, their flexible foam layers are designed to handle being vacuum-sealed and bounced back to shape later.
- All-Foam Mattresses: Much like memory foam models, traditional all-foam mattresses are made entirely of compressible materials, making them safe for at-home compression.
- Latex Mattresses: Natural or synthetic latex mattresses are also flexible enough for compression, though you might need to apply a bit more muscle to get them fully flattened.
- Hybrid Mattresses (With Caution): If your hybrid mattress has only a light layer of coils and mostly foam components, you may be able to compress it as well. However, always double-check the manufacturer’s care instructions—too much force could damage internal springs.
On the other hand, it’s best to avoid compressing traditional innerspring mattresses at home. Their steel coil interiors aren’t meant to be squished and could break or bend in the process.
When in doubt, refer to your mattress tag or purchase manual to confirm its construction before you begin. Properly identifying your mattress type will help you avoid any unintended mishaps and keep your bed in top shape after its journey.
Why You Shouldn’t Compress Innerspring Mattresses Yourself
While compressing foam mattresses is fairly straightforward, innerspring mattresses are a different story. These mattresses are built with metal coils that form their main support system—coils that aren’t meant to endure the intense pressure of vacuum compression.
Attempting to compress an innerspring mattress yourself can have some unpleasant consequences:
- The metal coils might bend or snap, leaving you with permanent lumps or sharp pressure points.
- Damaged coils may push through the fabric, potentially creating tears or even a safety hazard.
- Since these mattresses are designed to hold their shape—not to be squashed like memory foam—once the coils are compromised, it’s almost impossible to restore the original comfort.
For these reasons, innerspring (and many coil-based hybrid) mattresses should always be transported flat. If you need to move one, consider enlisting professional movers who have the right equipment and techniques to keep the mattress safe and intact.
What Are the Risks of Compressing an Old Mattress?
Compressing an older mattress may sound convenient, but it can be risky business for your bed’s longevity.
Older mattresses—especially those over seven years old—often have foam, springs, or materials that aren’t as resilient as they once were. When you compress them, the internal structure can crack, crumble, or lose its shape, making it tough (if not impossible) for the mattress to fully rebound once it’s unpacked.
Memory foam, in particular, tends to lose elasticity with age. So, instead of bouncing back to its original form, an old foam mattress might remain lumpy or permanently dented after compression.
A few key risks to keep in mind:
- Permanent damage: Aging materials may break down under pressure and never recover.
- Loss of comfort: Sagging or uneven surfaces could result, affecting your sleep quality.
- Shorter lifespan: An older mattress that’s been compressed may reach the end of its usable life sooner than expected.
If your mattress is already showing signs of wear, consider if compressing it is worth the trade-off. When in doubt, limit the time your mattress stays compressed—or skip compression altogether to preserve comfort and support.
What Tools Are Needed to Compress a Mattress?
To effectively compress a mattress, you need the right tools.
Essential tools include a vacuum-sealed bag, a vacuum pump, sturdy straps, and a protective bag to ensure safe storage and transportation.
| Tool | Purpose |
|---|---|
| Vacuum Bag | Compresses the mattress by removing air |
| Vacuum Pump | Extracts air efficiently from the vacuum bag |
| Straps/Ropes | Secures the compressed mattress to prevent expansion |
| Protective Bag | Shields the mattress from dust and damage |
Can Any Type of Mattress Be Compressed at Home?
While compressing a mattress is convenient, not every type is suited for this process.
Memory foam and all-foam mattresses are the best candidates, as they’re flexible and lack internal metal parts. Some hybrids with very few coils may also handle compression, but it’s crucial to consult your manufacturer’s recommendations beforehand.
On the other hand, traditional innerspring mattresses are not suitable for home compression. The metal coils inside can bend or break, leading to permanent damage. Latex mattresses can be compressed, but their denser build requires greater force and care to avoid harm.
In summary:
- Safe to Compress at Home: Memory foam, all-foam, and some hybrids with minimal coils (check guidelines).
- Not Safe to Compress: Innerspring mattresses and more rigid hybrid models.
Always verify with the manufacturer when in doubt to keep your mattress in top shape.
What Types of Mattresses Should You Avoid Compressing at Home?
While compressing a mattress can make moving easier, not every type of mattress is a good fit for DIY compression. Some mattresses simply aren’t built to handle the process and can be damaged—or even ruined—if you try.
Steer clear of compressing these kinds of mattresses:
- Traditional Innerspring Mattresses
Mattresses with metal coils at their core aren’t designed for compression. The internal springs can bend or break under pressure, ruining the mattress’s support. You also run the risk of sharp coils poking through the fabric—a safety hazard and a fast track to the junk pile. Most moving experts recommend handling innerspring mattresses flat and avoiding vacuum sealing altogether. - Very Old Mattresses
If your mattress is older than seven years, the internal materials—especially foams and adhesives—may have weakened with time. Compression might cause the foam to crack or layers to separate, speeding up wear and tear. In many cases, it’s safer (and sometimes time to consider an upgrade) to move older mattresses flat and uncompressed. - Already Damaged Mattresses
Mattresses that have visible tears, sagging, water damage, or areas that have been previously repaired are poor candidates for compression. Existing damage can get much worse under vacuum pressure, sometimes rendering the mattress unusable. Water-logged spots, in particular, can trap moisture inside a tightly sealed bag, creating a risk for mold growth.
As a rule, thoroughly inspect your mattress before starting. If you spot any damage or if the mattress is on the older side, it’s best to err on the side of caution and use a flat moving method instead. This will help extend the mattress’s lifespan and prevent any unpleasant surprises when you set it back up.

How to Identify Your Mattress Type—and Why It Matters for Compression
Before compressing your mattress, it’s important to know what type you have. Mattress construction affects both the ease and safety of compression. Here’s how to distinguish between memory foam, latex, hybrid, and innerspring mattresses—and why this matters.
Memory Foam and All-Foam Mattresses:
These are usually the easiest to compress. Memory foam mattresses don’t contain metal coils or rigid parts, making them flexible enough to vacuum-seal without damage. If your mattress returns to its shape quickly after pressure and feels uniformly dense, chances are it’s memory foam or all-foam. Many boxed mattresses, like those from Casper or Tuft & Needle, use this design.
Latex Mattresses:
Latex mattresses are also foam-based but can feel slightly heavier and springier compared to memory foam. They compress relatively well, though you may need a bit more effort to flatten their denser structure.
Hybrid Mattresses:
Hybrids combine foam layers with some inner coils. While many hybrids can be compressed at home—especially those advertised to ship in boxes—it’s wise to consult the manufacturer’s instructions before proceeding. Too much force can bend or damage the supportive coils.
Innerspring Mattresses:
Traditional innerspring mattresses contain a core of metal springs, making them less suitable for compression. Compressing these at home often risks bending, breaking, or permanently damaging the inner structure.
How to Check:
- Look for tags: The mattress tag or law label typically lists materials and construction details.
- Review purchase information: Product descriptions, receipts, or manufacturer websites describe the mattress’s type.
- Test flexibility: Gently press or fold a small section; foam types will flex easily, while coil-based models resist.
Knowing your mattress’s construction helps you choose the safest compression method—and ensures your mattress stays in great shape after unboxing.
What Are Ratchet Straps and How Do They Help?
Ratchet straps are durable, adjustable straps designed to keep your mattress securely compressed once the air has been removed. By wrapping and tightening these straps around your rolled or folded mattress, you prevent it from expanding prematurely and make it much easier to lift and carry.
For best results, use at least two straps—one at each end of the mattress. If you’re dealing with a larger size, adding a third strap around the middle offers extra security and support, ensuring the mattress stays compact during transport or storage.
How to Clean a Mattress Before Compression?
Cleaning the mattress before compression prevents odors and mold growth.
Use a vacuum cleaner to remove dust, a mild cleaner for stains, and ensure the mattress is completely dry before sealing it.
Cleaning Steps:
- Vacuum: Remove dust and debris from the surface.
- Spot Clean: Use a stain remover for visible marks.
- Air Dry: Ensure the mattress is fully dry before compression.
How to Prepare a Mattress for Compression?
Protecting the mattress before compression ensures a safe and efficient process.
Wrap the mattress in a protective plastic cover or use a mattress bag to prevent tearing and contamination during compression.
Risks of Folding or Sharply Bending a Mattress
Avoid the temptation to fold your mattress in half, as this can lead to lasting damage. Sharp bends or folds introduce deep creases that memory foam and other materials often can’t recover from after decompression.
Key risks include:
- Permanent Creases: Folding creates hard-to-remove ridges, especially in the corners, that may impact comfort and support.
- Structural Damage: Too much bending can weaken or break down the mattress’s internal layers—diminishing its ability to provide proper spinal alignment or pressure relief.
- Sleep Quality Issues: Irreversible creases and deformities can lead to uneven sleeping surfaces or lumps that interfere with restful sleep.
If you must maneuver the mattress through tight spaces, roll it gently or use items like rolled towels along the fold lines to create a wider, softer bend—never a sharp angle. Remember, damage from improper handling may not show up until your mattress is unwrapped and fails to expand as intended.
Is It Safe to Compress an Old or Damaged Mattress?
Compressing older or already compromised mattresses usually ends up causing more harm than good.
Old mattresses—especially those over seven years old—tend to have internal wear and tear that makes them much less resilient. The foam loses springiness and the structural layers aren’t as stable, meaning compression can accelerate break-down and even cause permanent damage.
Visible signs of damage, such as rips, sagging, or previous repairs, are red flags. Compressing a mattress with these issues can make small problems much worse, sometimes to the point where the bed becomes unusable. Water damage is especially risky, as sealing in moisture under compression can lead to mold growth.
If your mattress is already showing its age or has spots that look worse for wear, it’s generally safer to transport it flat rather than compress it. Sometimes, what looks like a minor flaw can turn into a major issue once compression pressure is applied. When in doubt, a careful inspection beforehand can save you a lot of hassle—and possibly help you decide whether it’s time for a replacement instead.
Consider the Age of Your Mattress
Mattress age plays a big role in whether compression is safe—or risky.
Newer mattresses (typically less than three years old) are usually in prime condition for compression. Their materials, especially memory foam or latex layers, maintain resilience and bounce back well after being compressed.
Older mattresses, however, can be a different story. As foam ages—usually after about seven years—it starts to break down internally. That means the inner layers may crack, crumble, or lose their original shape once compressed and released. Memory foam, in particular, can become less elastic over the years, making it harder for your mattress to fully recover.
So, if your mattress is on the older side, try to compress it only for short periods (ideally under a week) to avoid lasting damage. Taking your mattress’s age into account helps you avoid any unwelcome surprises when it’s time to unroll.
Inspect for Signs of Damage Before Compressing
Before you begin compressing your mattress, take a few moments to carefully inspect it for any signs of damage that could worsen during the process.
- Surface Tears and Weak Spots: Examine the entire surface, especially along seams and edges, for rips or small holes. These vulnerable areas can become much larger under compression.
- Check Under the Cover: If your mattress has a removable cover, unzip it and look over the inner foam layers for visible wear or crumbling.
- Look for Stains: Water stains may indicate hidden moisture problems like mold or mildew, which can spread further once the mattress is compressed.
- Test for Uneven Spots: Press on various areas to identify any weak sections or sagging that differs from the rest of the mattress.
If you notice any of these issues, it’s wise to address repairs first or consider alternative moving options to avoid permanent damage.
Preparation Steps:
- Measure the Mattress: Choose a vacuum bag that fits the mattress size.
- Cover the Mattress: Use plastic wrapping for extra protection.
- Seal the Edges: Ensure no gaps remain before vacuum sealing.
What Are the Risks of Compressing a Very Old Mattress?
While compression is a great solution for most mattresses, it can spell trouble for older ones.
Mattresses over seven years old often have weakened internal structures and delicate materials that simply aren’t up to the pressure and manipulation required by compression. The foam inside may have lost its original springiness, making it much harder for the mattress to regain its shape once unpacked.
Older memory foam, for example, can develop tiny cracks over the years. Compressing such a mattress pushes these microcracks to the limit, sometimes resulting in larger splits or crumbling foam. The glues and adhesives holding multiple layers together can also dry out and lose their grip, leading to layers shifting or peeling apart while the mattress is compressed.
Choosing to compress a mattress past its prime may accelerate wear and tear, possibly shortening its lifespan considerably. If the mattress is due for replacement soon, it may be wiser to consider responsibly disposing of it rather than risking further damage with compression.
For those who absolutely need to move an old mattress, it’s safest to keep it flat during transport instead of compressing it. This reduces the risk of further damage and helps the mattress retain whatever comfort and structure remain.
Why Should You Avoid Sharp Bends or Folds During Mattress Compression?
Taking care to avoid sharp bends or folds when compressing your mattress is crucial for preserving its structure and comfort.
Folding a mattress in half or making sharp creases can cause permanent damage. Memory foam and other core materials are sensitive to stress—bending them sharply can create ridges or weak spots that won’t disappear after the mattress is unrolled. Over time, these deformations can lead to lumps or uneven support, ultimately affecting how well you sleep.
When you need to make your mattress more compact, it’s best to roll it gently rather than folding. If you have to bend the mattress to maneuver through a doorway, create as smooth a curve as possible; you can even place pool noodles or rolled towels along the fold lines for extra protection against sharp angles.
Even if the damage isn’t visible right away, it often becomes noticeable after decompression—so treating your mattress gently during the compression process helps ensure it will return to its original, comfortable shape when you’re ready to use it again.
How to Compress a Mattress Using a Vacuum Bag?
Vacuum sealing is the most effective method for mattress compression.
Place the mattress inside the vacuum bag, connect the vacuum pump, and remove all air until the mattress is fully compressed.
Step-by-Step Vacuum Compression:
- Insert the Mattress: Place the mattress flat inside the vacuum bag.
- Seal the Bag: Ensure an airtight closure before vacuuming.
- Connect the Vacuum Pump: Attach the pump to the valve and start suction.
- Extract the Air: Continue until the mattress is significantly reduced in size.
- Secure the Seal: Close the valve tightly to prevent air from re-entering.
How to Secure a Compressed Mattress?
Once compressed, securing the mattress prevents expansion.
Use durable straps or strong rope to tie the mattress and maintain its compact form.
Securing Steps:
- Tie with Straps: Use multiple straps to secure the compressed shape.
- Wrap Again (Optional): Place the mattress in an additional protective bag.
- Check for Stability: Ensure the mattress remains in its compressed state.
How to Store or Transport a Compressed Mattress?
Proper storage and transportation protect the mattress from damage.
Keep the compressed mattress in a dry, cool place, and handle it gently during transport to avoid punctures or damage.
How Long Can You Safely Keep a Mattress Compressed?
If you’re wondering how long it’s safe to keep your mattress compressed, the general rule is no longer than two weeks. Most memory foam and bed-in-a-box mattresses can start to suffer permanent damage if left compressed for too long—even those fancy new models aren’t immune.
Leaving a mattress in its compressed state beyond that window can lead to sagging, compromised support, or foam that just doesn’t bounce back. If your plans change and you need to extend storage, it’s better to unroll the mattress and let it fully expand, then re-compress it later if necessary. And always keep extreme temperatures and humidity in mind, as these can speed up potential damage.
How Long Can You Safely Keep a Mattress Compressed?
Keeping a memory foam mattress compressed for too long can lead to permanent damage. Most manufacturers recommend that you do not leave your mattress compressed for more than two weeks. Exceeding this window increases the risk that the mattress won’t fully expand or regain its original shape once you unbox it.
Both new and older mattresses can suffer if stored compressed beyond this safe period—age may offer some flexibility, but it’s best not to push your luck. If your plans change and you can’t set up your mattress within two weeks, unbox it and let it expand until you’re ready to move it again, rather than leaving it compressed for an extended stretch.
Finally, always review the manufacturer’s care instructions or warranty details. Some may specify exact time limits for safe compression based on materials and construction. High heat or humidity can further stress the mattress, so try to minimize exposure to these conditions while it’s packed away.
Best Practices for Storage & Transport:
- Store in an Upright Position: Prevents unnecessary pressure on the mattress.
- Avoid Sharp Objects: Keep away from items that could puncture the bag.
- Use Proper Handling: Lift carefully to maintain compression.
- Check Regularly: Inspect for any leaks or loss of compression.
How to Restore a Compressed Mattress?
When ready to use, decompress the mattress properly for best results.
Unseal the vacuum bag, place the mattress on a flat surface, and allow 24-48 hours for full expansion.
Unpacking and Expanding Steps:
- Carefully Unseal the Bag: Avoid using sharp objects.
- Lay the Mattress Flat: Place it in a well-ventilated area.
- Allow Full Expansion: Give it 24-48 hours to regain shape.
- Fluff and Rotate: Shake or rotate the mattress to speed up expansion.
How to Check for Compression Damage
After decompressing your mattress, it’s important to inspect for any signs of damage caused by compression.
Look and feel for these common indicators:
- Surface Irregularities: Gently run your hands over the entire mattress to spot areas that feel lumpy, sunken, or noticeably different from the surrounding surface.
- Corner and Edge Checks: Pay close attention to the corners and edges—these spots are most vulnerable to creasing or flattening.
- Sleep Test: Lie down in your preferred position and notice any uncomfortable spots or uneven support that weren’t present before compression.
Minor bumps or irregularities should smooth out within a week as the mattress fully recovers. However, if you notice deep creases, lasting lumps, or an uneven sleeping surface that does not improve, this is a sign of compression damage. Early detection helps you address warranty issues or consider replacement if needed.
What if Your Mattress Doesn’t Fully Expand After Compression?
If your mattress hasn’t fully regained its shape after decompression, a little patience and a few simple steps can help.
- Wait It Out: Allow the mattress a full 24 to 72 hours in a warm, well-ventilated room. Some mattresses, especially memory foam, may take longer to expand at the center or corners.
- Light Pressure: Gently walk across the surface (wearing clean socks) to encourage the foam to expand, especially in areas that seem stubborn.
- Check Conditions: Ensure the room is warm, as cold temperatures can slow the expansion process.
- Manufacturer Guidance: If the mattress still hasn’t reached its full size after three days, consult the manufacturer for specific recommendations for your model.
With these steps, most mattresses will eventually reach their intended shape and comfort.
What If Your Mattress Doesn’t Fully Expand?
If your mattress hasn’t fully expanded after the recommended waiting period, don’t panic—this is a common occurrence, especially with memory foam models.
Troubleshooting Steps:
- Give It Extra Time: Sometimes, mattresses need a bit longer, especially in cooler or less ventilated rooms. Leave it to sit, ideally in a warm, well-ventilated space, for an additional 24-48 hours.
- Even Out the Expansion: Gently walk on the mattress with clean socks, focusing on areas that appear flatter or haven’t puffed up as much. This can help activate the foam cells and encourage them to expand.
- Check the Room Conditions: Low temperatures and high humidity can slow expansion. Try increasing airflow or temporarily warming the room if safe and possible.
- Contact Customer Support: If your mattress remains uneven or compressed after several days, reach out to the manufacturer for guidance. They may be able to provide further instructions or determine if there’s a defect that needs addressing.
Is It Safe to Sleep on a Mattress Right After Decompression?
It’s best to give your freshly decompressed mattress a bit of patience before hopping on for a full night’s sleep. Most manufacturers recommend letting the mattress air out and fully expand for 24–72 hours before using it. This waiting period allows the foam to inflate completely, prevents the risk of permanent body impressions, and gives any lingering odors from packaging a chance to dissipate.
That said, if you’re in a pinch and need to use the mattress sooner, one night of sleep—especially if the mattress has mostly regained its shape (usually at least 90%)—typically won’t cause lasting damage. Just remember, the longer you wait, the better your mattress will perform in the long run.
How to Inspect Your Mattress for Damage After Decompression
After your mattress has had time to fully expand, it’s essential to check for any issues that may have arisen during compression or transport.
Damage Inspection Steps:
- Surface Check:
Gently run your hands across the mattress, feeling for lumps, dents, or uneven spots. Pay extra attention to the edges and corners—these areas are most likely to show signs of creasing or damage. - Visual Assessment:
Look over all sides of the mattress for tears, cuts, or holes that could have happened while moving or unbagging. Check the cover for any signs of stretching or fabric stress. - Comfort Test:
Lie down in your usual sleeping position and notice any areas that feel less supportive or unusually firm. Sometimes, small irregularities will smooth themselves out after a few days. - Documentation:
If you find any noticeable damage—such as deep creases, tears, or large indents—take clear photos. This will be helpful for warranty inquiries or insurance purposes. - Give It Time:
Minor imperfections, especially with memory foam, often resolve within a week as the mattress continues to recover. However, if major concerns persist, reach out to the manufacturer to discuss next steps or warranty coverage.
Conclusion
Compressing a mattress is a straightforward process that requires the right tools and techniques. By cleaning, vacuum-sealing, securing, and storing the mattress correctly, you can ensure safe transportation and long-term preservation of its quality.
