Choosing a mattress in Singapore often comes down to two very different options: natural latex and polyurethane (PU) foam.
Natural latex comes from the sap of the rubber tree. It’s valued for being responsive, durable, and naturally breathable.
Polyurethane foam is a synthetic material made from petrochemicals. It’s affordable, widely used, and comes in several grades, from basic polyfoam to memory foam.
In this guide, we’ll look at what each material is, how they compare in comfort and durability, and what factors matter most for Singapore buyers.

What is a Natural Latex Mattress?
A natural latex mattress is made entirely from the sap of the rubber tree (Hevea brasiliensis). The sap is whipped, poured into moulds, and baked into foam blocks that form the mattress core.
There are two types of natural latex:
Dunlop latex — denser, firmer, more common.
Talalay latex — lighter, airier, more buoyant.
Natural latex feels springy and supportive without the ‘stuck’ sensation of memory foam. True natural latex means 100% tree-derived material, not blended with petrochemicals.
Certified latex mattresses are durable, breathable, and chemical-safe, making them suitable for Singapore’s hot and humid climate.
What is a Polyurethane Foam (PU) Mattress?
A polyurethane (PU) foam mattress is made from synthetic petrochemical-based foam. It is one of the most common mattress materials in Singapore, used in both budget beds and premium models. PU foam comes in three main grades:
Regular PU foam — inexpensive, least durable.
High-density (HD) foam — denser, slightly more supportive, often used in budget mattresses.
High-resiliency (HR) foam — more durable and supportive, sometimes used in higher-end beds.
Memory foam is a subtype of PU foam. It feels soft and contouring but traps more heat. PU foam is affordable and widely available, making it attractive for short-term or budget-conscious buyers. However, it wears out faster than natural latex, typically sagging within 5–7 years.
Natural Latex Mattress vs Poly Foam Mattress: Side-by-Side Comparison Table
Category | Natural Latex Mattress | Poly Foam Mattress |
Supports your spine and posture? | ✔️ Yes. Excellent spinal alignment and pressure relief. | ❌ No. Lower-density foams sag quickly and offer poor alignment. |
Long lifespan? | ✔️ Yes. 10 to 15+ years without sagging. | ❌ No. PU foam typically lasts around 5–7 years before sagging or losing support. |
Will you feel your partner move? | ✔️ Yes. Limits most motion so you’re less likely to feel a partner move. | Partially. Absorbs some movement, but less effective than latex or memory foam. |
Will the mattress keep you cool at night? | ✔️ Yes. Naturally breathable and stays cooler in humid climates like Singapore. | ❌ No. Foam tends to trap heat, especially in denser grades. |
Is the mattress hypoallergenic? | ✔️ Yes. Naturally resistant to dust mites, mould, and mildew. | ❌ No. Can trap allergens and moisture. Not naturally hypoallergenic. |
Is the mattress quiet? | ✔️ Yes. No springs, no squeaks. | ✔️ Yes. Foam absorbs sound. |
Is the mattress chemical-free? | ✔️ Yes. Free from harmful chemicals, VOCs, and off-gassing. | ❌ No. Made from petrochemicals. Can contain additives and often off-gasses chemical odors. |
Is the mattress eco-friendly? | ✔️ Yes. Renewable, biodegradable, and available with trusted eco-certifications. | ❌ No. Synthetic and non-biodegradable. Petroleum-based, not sustainable. |

1. Spinal Support and Posture
Natural latex provides superior spinal alignment compared to PU foam. A study in the Journal of Physical Therapy Science found that latex mattresses distributed body pressure more evenly than polyurethane foam, reducing strain on shoulders and hips.
Natural latex:
Consistent support across the body
Helps reduce back and shoulder pain
Keeps structure over years
Polyurethane foam:
Lower-density foam softens quickly
Sagging leads to poor alignment
Even high-density grades decline faster than latex
2. Lifespan and Durability
Natural latex mattresses last far longer than poly foam. High-quality natural latex mattresses last 10–15 years or more. Latex resists sagging because it springs back into shape instead of forming deep impressions.
Natural latex:
Resists sagging and body impressions
Springs back into shape
Warranties of 10+ years are common
Polyurethane foam:
Breaks down within 5–7 years
Loses firmness more quickly
Shorter warranties reflect lower durability
3. Cooling and Breathability
Latex sleeps cooler than PU foam, especially in Singapore’s humid climate. Research on mattress ventilation confirms latex promotes better breathability and helps prevent overheating (study on body pressure and ventilation).
Natural latex:
Naturally ventilated design
Cooler than PU or memory foam
Suitable for hot and humid climates
Polyurethane foam:
Dense foams trap heat
“Sleeping hot” is a common complaint
Added gels or metals help but only partly
4. Chemical Safety and Off-Gassing
For health-conscious buyers, this matters most. Certified natural latex with eco-INSTITUT or OEKO-TEX Standard 100 (Class 1) labels is tested to be free from harmful substances and has very low VOC emissions.
Natural latex:
Safe when certified by eco-INSTITUT or OEKO-TEX
Very low emissions
Polyurethane foam:
Made from petrochemicals
Can release VOCs (that “new mattress” chemical smell)
Even CertiPUR-US only restricts certain chemicals — it doesn’t make the foam natural
A 2022 study in Chemosphere found new PU foam mattresses emitted multiple VOCs. The Danish EPA has also flagged PU foam products for indoor VOC release.
5. Value Over Time
Latex has better long-term value despite a higher upfront cost.
Natural latex:
$2,000 mattress lasting 15+ years = ~$133 per year
Longer replacement cycle reduces waste
Polyurethane foam:
$900 mattress lasting 5 years = ~$180 per year
Frequent replacements cost more in the long run
What Matters Most for Singapore Mattress Buyers
When choosing a mattress in Singapore, a few factors stand out:
Heat and humidity management - With year-round temperatures around 30°C and 80-90% humidity, your mattress needs to breathe. Waking up in a sweat isn't just uncomfortable—it disrupts sleep quality night after night. Natural latex's open-cell structure allows airflow, while most PU foams trap body heat and moisture.
Long-term value - In Singapore's high-cost environment, a mattress represents a significant investment. When quality natural latex lasts 12-15 years compared to 5-7 years for typical PU foam, you're looking at potentially buying two or three PU mattresses in the time one latex mattress serves you.
Health-conscious materials - Singapore consumers increasingly prioritize low-emission, certified materials. Look for OEKO-TEX Standard 100 or eco-INSTITUT certifications, which test for harmful chemicals and VOCs. This matters especially for families with young children or anyone sensitive to synthetic materials.
How to Choose Between Latex and Polyurethane Mattresses?
Choose a Natural Latex Mattress if you:
Want a mattress that lasts 10-15+ years without sagging
Sleep hot or live in Singapore's humid climate
Have back pain, joint issues, or allergies
Value long-term savings over upfront cost

Don't mind replacing your mattress every 3-5 years
Want to try a mattress type before investing in higher quality
Are furnishing a spare bedroom that gets occasional use
Final Takeaway
For Singapore's climate and cost of living, natural latex delivers better long-term value. It stays cooler in humidity, lasts 10-15+ years, and provides healthier sleep without chemical off-gassing.
Polyurethane Foam works well for temporary needs or strict budgets, but when it comes to your primary mattress, latex typically offers superior comfort, durability, and overall value per year of use.

FAQs
Does a natural latex mattress stay cooler than polyurethane foam in Singapore’s climate?
A natural latex mattress stays cooler than PU foam in Singapore’s humid climate due to its open-cell structure and breathability. Latex promotes airflow and reduces heat retention, while PU foam traps heat. This makes latex better for hot sleepers in tropical environments.
How many years can I expect a natural latex mattress to last compared to polyurethane foam?
A natural latex mattress lasts 10-15+ years, while PU foam typically lasts 5–7 years. Latex resists sagging and wear, offering long-term durability. PU foam breaks down faster due to oxidation and compression. Latex offers triple the lifespan under normal use conditions.
Are natural latex mattresses safer and more hypoallergenic than polyurethane foam?
Natural latex mattresses are safer and more hypoallergenic than PU foam. Latex is resistant to dust mites, mould, and bacteria, and contains fewer VOCs. PU foam can emit harmful chemicals and may trigger allergies. Latex is ideal for sensitive individuals.
Why does natural latex cost more than polyurethane foam?
Natural latex costs more than polyurethane foam due to labor-intensive harvesting, eco-friendly processing, and longer lifespan. Latex is derived from rubber tree sap, requiring sustainable farming. PU foam is synthetic, cheaper to produce, and degrades faster, reducing its long-term value.
Who should choose natural latex, and who should choose PU foam?
Choose natural latex if you want durability, support, cooling, and low allergens. Choose polyurethane foam if you need a budget-friendly, softer mattress for short-term use. Latex suits hot sleepers and allergy-sensitive users. PU foam suits those prioritizing price over longevity.
