Memory Foam vs Regular Foam: Choosing the Best Material for Your Foldable Mattress
What’s better for a foldable mattress in Australia—memory foam or regular foam? In Australia, memory foam offers excellent pressure relief and comfort for foldable mattresses, while regular foam is more affordable, cooler, and easier to transport. Choose memory foam for nightly comfort or regular foam for guests, kids, or camping.
When shopping for a foldable foam mattress, one of the most important decisions you'll face is choosing between memory foam and regular polyurethane foam. This choice significantly impacts comfort, durability, price, and overall satisfaction with your purchase. In this comprehensive guide, we'll explore the differences between these materials, their pros and cons, and help you determine which is best suited for your specific needs.
Whether you're looking for a foldable memory foam mattress for guests, camping, or everyday use, understanding the material differences will ensure you make an informed decision that provides the comfort and support you need.
Understanding Different Foam Types
Before diving into comparisons, it's essential to understand what each foam type actually is and how they're made. This foundation will help you better appreciate their differences in performance and suitability for foldable mattresses.
What is Memory Foam?
Memory foam (technically called viscoelastic polyurethane foam) was originally developed by NASA in the 1960s to improve seat cushioning and crash protection for astronauts. This specialized material is distinguished by its ability to respond to heat and pressure, allowing it to contour precisely to the body's shape.
When you lie on a foldable memory foam mattress, the material temporarily "remembers" your body impression, hence the name "memory" foam. Once pressure is removed, it slowly returns to its original shape. This unique property provides exceptional pressure relief by distributing body weight evenly across the surface.
What is Regular Foam?
Regular foam, often called polyurethane foam or poly-foam, is the standard foam used in many furniture and mattress applications. It's made from petrochemicals and is available in various densities and firmness levels. Unlike memory foam, regular foam has an immediate response to pressure—it compresses when weight is applied and returns to shape quickly when the weight is removed.
In foldable foam mattresses, regular polyurethane foam provides a more consistent feel throughout the sleeping surface and typically offers firmer support than memory foam alternatives.
Other Foam Variations
While memory foam and regular polyurethane foam are the most common materials in foldable mattresses, there are other variations worth mentioning:
- Gel-infused memory foam: Memory foam infused with cooling gel particles to help dissipate heat
- Plant-based memory foam: Partially replaces petroleum products with plant-derived oils for a more eco-friendly option
- High-resilience foam: A premium type of polyurethane foam with greater durability and responsiveness
- Latex foam: Though less common in foldable mattresses due to its weight and cost, natural or synthetic latex offers exceptional durability and responsiveness
Memory Foam Benefits and Drawbacks
Memory foam has revolutionized the mattress industry, including the market for foldable memory foam mattresses. Let's explore its advantages and limitations:
Benefits of Memory Foam
- Superior Pressure Relief: Memory foam excels at reducing pressure points by contouring to the body's curves, making it ideal for side sleepers and those with joint pain.
- Motion Isolation: The energy-absorbing properties of memory foam minimize motion transfer, meaning one person's movements are less likely to disturb another.
- Spinal Alignment: By conforming to the body's natural shape, memory foam helps maintain proper spinal alignment during sleep.
- Durability: Quality memory foam typically outlasts regular foam, especially in higher densities (5+ pounds per cubic foot).
- Hypoallergenic Properties: The dense structure of memory foam resists dust mites and other allergens better than traditional mattress materials.
Drawbacks of Memory Foam
- Heat Retention: Traditional memory foam can trap body heat, potentially causing discomfort for hot sleepers (though newer cooling technologies address this issue).
- Slow Response Time: The slow-recovering nature of memory foam can make changing positions more difficult, which some sleepers find restrictive.
- Initial Odor: New memory foam products often emit a temporary chemical smell (off-gassing) that dissipates over time but may be bothersome initially.
- Higher Cost: Memory foam is typically more expensive than regular polyurethane foam.
- Weight: Memory foam is denser and heavier than regular foam, potentially making a foldable memory foam bed less portable.

Regular Foam Benefits and Drawbacks
Regular polyurethane foam remains a popular choice for foldable foam mattresses due to several distinct advantages. However, it also has limitations worth considering:
Benefits of Regular Foam
- Affordability: Regular foam is significantly less expensive than memory foam, making it a budget-friendly option.
- Lightweight: The lower density of regular foam makes foam mattress foldable products lighter and easier to transport.
- Quick Response: Regular foam bounces back immediately when pressure is removed, making it easier to change positions during sleep.
- Cooler Sleep: The open-cell structure of regular foam typically allows for better airflow than traditional memory foam, resulting in a cooler sleeping experience.
- Variety of Firmness Options: Regular foam is available in a wide range of firmness levels, from very soft to extra firm.
Drawbacks of Regular Foam
- Less Pressure Relief: Regular foam doesn't contour to the body as precisely as memory foam, potentially creating pressure points for some sleepers.
- Shorter Lifespan: Lower-density regular foam typically deteriorates faster than memory foam, developing impressions and losing support over time.
- Less Motion Isolation: Movement transfers more easily across regular foam, potentially disturbing sleep partners.
- Lower Density Options: Many budget foldable foam mattresses use low-density foam (under 1.5 pounds per cubic foot) that compresses quickly with regular use.
- Less Support: Regular foam may not provide adequate support for heavier individuals or those with specific support needs.

Which Material is Best for Different Needs
The ideal material for your foldable mattress depends largely on how you plan to use it. Let's explore which foam type works best for various common scenarios:
Best for Guest Accommodations
Recommendation: Memory Foam
When hosting guests, comfort is a priority. A foldable memory foam mattress provides superior pressure relief and support, helping ensure your visitors get a good night's sleep. The improved motion isolation is also beneficial when accommodating couples. Since guest mattresses are typically used intermittently, the higher cost of memory foam is offset by its longer lifespan.
Best for Camping and Outdoor Use
Recommendation: Regular Foam or Hybrid
For outdoor adventures, the lighter weight of regular foam makes it easier to transport. Regular foam also performs better in variable temperatures, as memory foam can become uncomfortably firm in cold environments. However, if comfort is your priority for "glamping," consider a hybrid option with a thin memory foam top layer over a regular foam base.
Best for Children
Recommendation: Regular Foam
For children's use, whether for sleepovers or play areas, regular foam offers practical advantages. It's more affordable (important since children outgrow or rough-handle items), recovers quickly from pressure (better for active use), and is lighter for kids to move themselves. The firmer support of regular foam is also generally better for growing bodies.
Best for Daily Use
Recommendation: High-Quality Memory Foam
If your foldable mattress will serve as a primary bed in a small space, investing in quality memory foam is worthwhile. Look for higher density (5+ pounds per cubic foot) memory foam that will maintain its supportive properties over years of nightly use. Consider gel-infused options if you tend to sleep hot.
Best for People with Pain or Mobility Issues
Recommendation: Memory Foam
The pressure-relieving properties of memory foam make it the superior choice for those with arthritis, fibromyalgia, or other conditions causing joint or muscle pain. However, those with mobility issues should consider that memory foam's slow response time can make changing positions more challenging.
Best for Hot Sleepers
Recommendation: Regular Foam or Gel-Infused Memory Foam
If you tend to sleep hot, regular foam's better airflow makes it a cooler option. Alternatively, look for memory foam specifically designed to address heat retention, such as open-cell or gel-infused varieties that promote better temperature regulation.
Hybrid Foam Options
Can't decide between memory foam and regular foam? Many manufacturers now offer hybrid foldable mattresses that combine the benefits of both materials:
Layered Construction
The most common hybrid approach features a comfort layer of memory foam (typically 1-2 inches) on top of a support core of firmer regular foam. This construction provides the pressure-relieving benefits of memory foam with the support, durability, and cost-effectiveness of regular foam.
Benefits of Hybrid Construction
- Balanced Comfort and Support: The memory foam top layer contours to the body while the regular foam base provides stable support.
- Improved Temperature Regulation: The regular foam base allows for better airflow than an all-memory foam design.
- Cost Efficiency: Hybrids are typically less expensive than full memory foam options while offering many of the same benefits.
- Reduced Weight: Hybrids are lighter than all-memory foam mattresses, making them more portable.
- Better Responsiveness: The regular foam base makes changing positions easier than with pure memory foam.
Considerations for Hybrid Foldable Mattresses
When evaluating hybrid options, pay attention to the thickness of each layer. A too-thin memory foam layer (less than 1 inch) may compress fully under body weight, negating its benefits. Conversely, a very thick memory foam layer on a foldable mattress may create pronounced creases at the fold points over time.
Why Foam Density Matters
Regardless of whether you choose memory foam or regular foam, density is perhaps the most important factor determining quality, comfort, and durability in a foldable foam mattress.
Understanding Foam Density
Foam density is measured in pounds per cubic foot (PCF) and indicates how much actual foam material is present in a given volume. Higher density means more material and less air, resulting in greater durability and support. However, density is not the same as firmness—you can have soft, high-density foam or firm, low-density foam.
Density Ranges for Memory Foam
- Low: 2.5-3.9 PCF - Budget options, suitable for occasional use, 2-5 year lifespan
- Medium: 4.0-5.0 PCF - Good quality, suitable for regular use, 5-7 year lifespan
- High: 5.1+ PCF - Premium quality, suitable for daily use, 7-10+ year lifespan
Density Ranges for Regular Polyurethane Foam
- Low: 1.0-1.5 PCF - Budget options, suitable for very occasional use, 1-3 year lifespan
- Medium: 1.6-2.0 PCF - Good quality, suitable for occasional use, 3-5 year lifespan
- High: 2.1+ PCF - Premium quality, suitable for regular use, 5-7 year lifespan
Impact of Density on Foldable Mattresses
In the context of foldable mattresses, density affects several key performance factors:
- Fold Recovery: Higher density foams generally retain fold lines longer but also resist permanent creasing better over time.
- Portability: Higher density means greater weight, potentially reducing portability.
- Support: Higher density foams provide more consistent support, especially important for heavier individuals.
- Value: While higher density foams cost more initially, their extended lifespan often makes them more economical in the long run.
For a foldable memory foam bed that will see regular use, we recommend looking for memory foam with at least 4.0 PCF density or regular foam with at least 1.8 PCF density to ensure adequate durability and support.
Important Certifications to Look For
When purchasing a foldable foam mattress, certifications provide assurance about safety, quality, and environmental standards. Here are the most important certifications to consider:
CertiPUR-US®
This certification ensures that the foam in your mattress is:
- Made without ozone depleters
- Made without PBDEs, TDCPP, or TCEP flame retardants
- Made without mercury, lead, and other heavy metals
- Made without formaldehyde
- Made without phthalates regulated by the Consumer Product Safety Commission
- Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million)
CertiPUR-US® is particularly important for both memory foam and regular polyurethane foam products.
OEKO-TEX® Standard 100
This certification focuses on the textile components (like mattress covers) and ensures they're free from harmful substances. Products with this certification have been tested for:
- Regulated and non-regulated harmful substances
- Chemicals that might be harmful to health
- Parameters for health protection
GREENGUARD and GREENGUARD Gold
These certifications focus on low chemical emissions, with GREENGUARD Gold having even stricter criteria. Certified products have been tested for thousands of chemicals and meet strict limits for VOC emissions.
Global Organic Textile Standard (GOTS)
If you're looking for organic components, particularly in the mattress cover, GOTS certification ensures that textiles meet environmental and social criteria along the entire organic supply chain.
While not all foldable mattresses will have every certification, products with one or more of these certifications demonstrate a manufacturer's commitment to safety and quality.
Maintenance Tips for Different Foam Types
Proper maintenance can significantly extend the life of your foldable foam mattress. However, care requirements differ somewhat between memory foam and regular foam:
Memory Foam Maintenance
- Rotation: Rotate your unfolded mattress end-to-end every 3-4 months to prevent uneven wear.
- Cleaning: Spot clean with mild soap and water. Never saturate memory foam as it can be difficult to dry completely.
- Storage: Store unfolded if possible for extended periods. If folded storage is necessary, unfold the mattress at least once a month to allow it to recover its shape.
- Protection: Use a waterproof mattress protector to prevent stains and moisture damage, which can be particularly difficult to address in memory foam.
- Temperature Considerations: Avoid exposing memory foam to extreme temperatures, which can affect its performance and longevity.
Regular Foam Maintenance
- Rotation: Rotate your unfolded mattress end-to-end every 2-3 months, as regular foam may develop impressions more quickly than memory foam.
- Cleaning: Spot clean with mild soap and water. Regular foam typically dries faster than memory foam but should still not be saturated.
- Storage: Regular foam generally recovers better from prolonged folding but should still be unfolded periodically to maintain its shape.
- Protection: A waterproof mattress protector is recommended, particularly for lower-density foams that may be more susceptible to damage.
- Weight Distribution: Avoid concentrating weight on a single area of the mattress, which can cause regular foam to compress permanently over time.
General Maintenance for All Foldable Mattresses
- Cover Care: If your mattress has a removable cover, wash it according to the manufacturer's instructions, typically every 1-3 months.
- Airing Out: Periodically air out your mattress in a well-ventilated area to prevent moisture buildup and odors.
- Sun Exposure: Occasional brief exposure to sunlight can help eliminate odors and kill bacteria, but avoid prolonged exposure, which can degrade foam materials.
- Fold Line Management: To minimize permanent creasing, vary the exact position of folds slightly each time you fold the mattress.
Frequently Asked Questions
How long do foldable foam mattresses typically last?
The lifespan of a foldable foam mattress depends primarily on the foam type, density, and frequency of use. High-density memory foam mattresses (5+ PCF) can last 7-10 years with occasional use, while medium-density options (4-5 PCF) typically last 5-7 years. Regular polyurethane foam mattresses generally have shorter lifespans, with high-density options (2.1+ PCF) lasting 5-7 years and lower-density versions lasting 1-5 years depending on quality and use. Frequent folding and unfolding can reduce these timeframes, particularly at the fold points.
Is memory foam or regular foam better for people with allergies?
Memory foam is generally better for allergy sufferers because its dense structure creates fewer spaces for dust mites, mold, and other allergens to accumulate. The viscoelastic nature of memory foam makes it naturally more resistant to dust mites compared to regular polyurethane foam. However, both foam types can cause issues for people with chemical sensitivities due to potential off-gassing. If allergies are a concern, look for CertiPUR-US certified foams with low VOC emissions and consider mattresses with removable, washable covers.
Do foldable foam mattresses work for all sleeping positions?
Different foam types better accommodate specific sleeping positions. Memory foam excels for side sleepers because it relieves pressure on shoulders and hips by contouring to these wider body parts. Back sleepers can do well on either memory foam or medium-firm regular foam that maintains proper spinal alignment. Stomach sleepers typically need firmer support to prevent excessive sinking of the midsection, making firmer regular foam often the better choice. For combination sleepers who change positions frequently, medium-firm regular foam or responsive memory foam formulations offer a good balance of comfort and ease of movement.
Can foldable foam mattresses cause back pain?
Inadequate support from a foldable mattress can potentially cause or exacerbate back pain. This is more likely with low-density foams that compress too easily or very thin mattresses (under 4 inches) that don't provide sufficient cushioning from hard surfaces beneath. For those with back concerns, a medium-firm to firm mattress with adequate thickness (6+ inches) is generally recommended. Memory foam can be beneficial for back pain sufferers due to its pressure-relieving properties, but it must have sufficient density and thickness to provide proper support. If using a foldable mattress regularly, consider a higher-quality option with appropriate support for your body weight and sleeping position.
How do I get rid of the chemical smell from a new foam mattress?
The chemical smell (off-gassing) from new foam mattresses is caused by VOCs released as the foam adjusts to room temperature. To minimize this odor: 1) Unpack the mattress in a well-ventilated area and allow it to air out for 24-72 hours before use; 2) Place the unfolded mattress in direct sunlight for a few hours if possible, as UV light can help break down VOCs; 3) Sprinkle baking soda on the surface, let it sit for several hours, then vacuum thoroughly; 4) Use activated charcoal odor absorbers in the room where the mattress is airing out. CertiPUR-US certified foams typically have lower VOC emissions and less pronounced odors. The smell should dissipate within a few days to a week, though some mattresses may take longer.
Conclusion
Choosing between memory foam and regular foam for your foldable mattress ultimately comes down to your specific needs, preferences, and budget. Memory foam offers superior pressure relief, motion isolation, and durability, making it ideal for those prioritizing comfort and support, particularly side sleepers and those with joint pain. Regular polyurethane foam provides better value, cooler sleep, and lighter weight, making it suitable for budget-conscious shoppers, hot sleepers, and those who need maximum portability.
For many users, hybrid options that combine a memory foam comfort layer with a regular foam support base offer an excellent middle ground, providing enhanced comfort while maintaining reasonable cost and weight.
Regardless of which material you choose, prioritize appropriate density for your intended use, look for relevant certifications, and follow proper maintenance procedures to maximize the lifespan of your investment. Remember that the best foldable foam mattress is one that meets your specific needs while providing comfortable, restful sleep.
