You spend about a third of your life sleeping.
But have you ever asked what your mattress is made of?
“Eco-friendly.” “Non-toxic.” “Natural.” These claims are everywhere. But in Singapore, where humidity traps air inside closed bedrooms, off-gassing from synthetic materials in your mattress may be making things worse.
It's no surprise more people are starting to ask if latex mattresses are safe and how to tell which ones actually are.
The truth? Not all latex mattresses are created equal. Some are genuinely safe. Many are just labeled that way.
In this Guide:
Why Mattress Safety Concerns Are Rising
TL;DR:
New mattresses may release chemical VOCs that affect indoor air quality and health
Many "eco-friendly" mattress claims are unverified or misleading
How Mattress Chemicals Affect Your Indoor Air
When was the last time you opened a new mattress and noticed that strong chemical smell? That smell often comes from VOCs like benzene and toluene, which are used in synthetic foams.
According to a report by Dreams.co.uk, the average person spends about 26 years of their life sleeping, which means we spend more time in contact with our mattresses than almost any other product in our homes. This raises the question, what exactly are we breathing in night after night.
According to research from the U.S. Environmental Protection Agency, VOC levels can be 2 to 5 times higher indoors than outdoors, with new furnishings being major contributors. While these chemicals help make mattresses flame-retardant, water-resistant, or simply cheaper to produce, they may also cause headaches, respiratory issues, and skin irritation in sensitive individuals.
What makes this issue more pressing is that bedroom air tends to circulate less than in other areas of the home. In Singapore's humid climate, where air conditioning often runs with windows closed, these chemicals can build up in the sleeping environment over time.
"Eco-Friendly" Claims Under Scrutiny
The mattress market has been flooded with "eco," "green," and "natural" claims that often don't stand up to close inspection.
According to a 2023 Consumer Reports survey of 2,088 shoppers, one of the top three priorities when buying a mattress was:
➤ “Comes with a label stating that its materials are not harmful to humans.”
This reflects a growing demand for transparency and certified safety over vague or unverified marketing claims.
Many mattress companies advertise products as "natural latex" when they actually contain significant amounts of synthetic materials.
Without clear labeling requirements, manufacturers can use terms like "eco-friendly" or "green" with minimal natural content.
This practice, known as greenwashing, has become so common that consumer protection agencies in several countries have started investigating misleading environmental claims in the bedding industry.
According to Singapore’s Ministry of Trade and Industry, the CPFTA protects consumers against businesses that make false or misleading environmental claims, and the CCCS is currently developing formal guidelines on the greenwashing issue.
What 'Safe' Really Means in Latex Mattresses
‘Safe’ means natural latex, not synthetic - here’s the difference
Natural latex is one of the cleanest mattress materials you can sleep on. When you hear the term ‘safe latex’, it almost exclusively means natural latex from the Hevea brasiliensis tree.
While synthetic latex may look and feel like natural latex, it’s the complete opposite, meaning more chemicals in your bedroom.
Here's a quick side by side look.
Natural Latex | Synthetic Latex | |
Source | Rubber Tree Sap | Petroleum-based compounds (e.g. SBR) |
Chemical content | ≤5% | Higher chemical load |
Off-gassing | None, rubber scent | High VOCs (e.g. toluene, benzene) |
Fire resistance | Inherent, no additives needed | Needs chemical flame retardants ( potential carcinogens) |
Environmental impact | Renewable, biodegradable | Non-renewable, polluting |
Common use of certifications | GOLS, OEKO-TEX | Rare or unclear |
The Dunlop vs Talalay Process
Even with natural latex, how it's made matters. The Dunlop process was developed in 1929. It makes latex denser, more supportive, and uses fewer additives.
The Talalay process is newer and involves vacuum sealing, flash freezing, and CO₂-based curing, followed by vulcanization.
According to Wikipedia, some manufacturers use only natural latex, while others mix in synthetic compounds like styrene-butadiene rubber depending on the brand.
Both are better than synthetic latex. But if you want the cleanest and safest option, go with Dunlop.
‘Safe’ means less VOCs and off-gassing
VOCs, or volatile organic compounds, can be released from your mattress into the air over time. These chemicals evaporate at room temperature and often get trapped in enclosed spaces like bedrooms.
In places like Singapore, where air conditioning is common and windows stay closed, off-gassing can build up over time.
Synthetic latex can release several VOCs. These include compounds like formaldehyde and benzene, which are not just unpleasant. In some people, they can cause noticeable symptoms.
Common short-term effects include:
Headaches
Dizziness
Throat or eye irritation
Difficulty breathing
Some VOCs found in household furnishings and materials, such as benzene and formaldehyde, are classified as known human carcinogens by the EPA and IARC. Synthetic mattresses made with polyurethane foam or chemical flame retardants can release these compounds into the air through off-gassing.
Children are especially vulnerable because their bodies are still developing and they breathe more rapidly than adults.
‘Safe’ means fire safety without the chemicals
In most countries, mattresses need to meet fire safety standards. That usually means they must be able to resist catching fire when exposed to an open flame.
In Singapore, bedding products like mattresses are tested under international fire safety standards such as ISO 12952. These tests check how easily a mattress might catch fire if exposed to something like a match.
Most synthetic mattresses rely on chemical flame retardants to meet the fire safety requirements. Some of these chemicals have been linked to hormone disruption and other health concerns.
Natural latex takes a different approach. It’s naturally flame resistant. Many manufacturers meet fire safety standards without adding flame retardant chemicals. Some also use wool as a natural fire barrier.
This gives you both fire protection and low chemical exposure in one mattress. That’s one reason health-conscious buyers often choose certified natural latex, even if it costs more.
‘Safe’ means environmentally friendly
Mattress safety isn’t just about what’s safe for your body. It’s also about what’s safe for the planet.
Natural latex is the eco-friendly choice:
It’s made from rubber trees, a renewable resource.
It breaks down naturally at the end of its life.
It’s processed using water-based methods that produce less pollution.
Other mattress types aren’t very friendly for the environment:
Type | Renewable? | Biodegradable? | Recyclable? | Pollution? | End of Life Impact |
Natural Latex | Yes (rubber tree) | Yes | Limited | Low (water based methods) | Breaks down naturally |
Synthetic Latex | No (petroleum) | No | No | High (chemical-heavy) | Remains in landfills |
Pocket Spring | Partial (steel) | No | Only if separated | Medium | Hard to recycle, mixed materials |
Memory Foam | No (petroleum) | No | No | High (energy-intensive) | Non-biodegradable waste |
When you choose natural latex, you’re choosing a cleaner product for your home and the planet.
Latex Mattress Certifications That Actually Matter
Mattress certifications can be confusing, especially with all the technical terms to describe their safety standards. Now that you know what "safe" really means in a latex mattress, here’s a simple guide to the certifications that actually matter:
If you see OEKO-TEX, it means the mattress has been tested for harmful chemicals and is safe to sleep on
The mattress is tested for over 100 harmful substances
→ You won’t be sleeping on a mattress that could affect your health
All parts of the mattress are tested, including the foam, fabric, stitching, and zippers
→ You won’t be exposed to hidden chemicals inside the mattress
The safety standards are strict enough for baby products
→ You’ll get a mattress that’s safe for sensitive skin and long-term use
The manufacturer sends in samples every year to keep the certification
→ You won’t be relying on outdated test results
Each certified mattress gets a unique number
→ You can look up the number on the OEKO-TEX website to confirm the certification is valid and up to date
If you see eco-INSTITUT, it means the mattress has been tested for chemical emissions and meets strict indoor air quality standards
The mattress is tested for VOCs like formaldehyde and other toxic gases
→ You won’t be breathing in harmful chemicals while you sleep
It also checks for things like pesticides, heavy metals, and flame retardants
→ You’ll avoid substances linked to long-term health risks
The certification is based on strict German standards
→ You’re getting a product held to some of the toughest air quality rules in the world
Testing focuses on low emissions, not just safe materials
→ Even natural materials can release gases, and this label helps you avoid that
eco-INSTITUT tests are done in independent labs
→ You can trust the results are real and not based on manufacturer claims
Be Careful with Vague or Unverified Labels
Some terms sound safe or eco-friendly but may not have clear definitions.
Watch for terms like:
"Eco-latex" — Often used in marketing but has no fixed meaning
"Natural blend" — Usually a mix of natural and synthetic latex
"Botanical" or "plant-derived" — Suggests natural content but doesn’t guarantee how much
"Chemical-free" — Technically inaccurate, since all materials contain chemicals, it’s more accurate to say ‘free from harmful chemicals’
"Green" or "Environmentally friendly" — Broad claims that vary between brands
If you see these terms being used that’s your cue to ask questions to clarify what they really mean.
Even well-known brands have come under scrutiny for this. In 2023, Avocado Mattress was named in a class-action lawsuit under California’s Consumers Legal Remedies Act. The complaint, reported by ClassAction.org, cited lab tests showing synthetic compounds (e.g., Wingstay‑L and naphthenic oils) despite the brand marketing mattresses as “natural” and “eco.” The case was later dismissed without any court ruling on whether the claims were accurate.

Health Considerations for Singapore Homes
Singapore’s humidity makes it easier for mould, dust mites, and heat to build up. A natural latex mattress can help you with healthier sleep.
Mould and Dust Mites Are Common in Humid Bedrooms
In Singapore, mould and dust mites are common in bedrooms due to the year-round humidity. These allergens thrive in warm, damp environments, especially in mattresses that trap moisture and lack airflow.
A study published in Clinical & Experimental Allergy found that mattresses in Singapore homes had the highest concentration of dust mite allergens among all indoor surfaces tested.
Natural latex helps prevent this. It resists moisture buildup and allows air to flow freely, making it harder for mould or mites to survive.
If you’ve noticed musty smells, skin irritation, or sneezing in the morning, your mattress could be contributing. Choosing hypoallergenic materials that resist these issues can support cleaner, healthier sleep.
Just to add, when it comes to bed bugs, no mattress is fully protected, no matter what it's made of. While bed bugs likely won’t burrow into latex like they might in an innerspring mattress, they can still live on the surface if they get into your home. So it’s important to clean and care for your mattress regularly.
Poor Indoor Air Can Affect Your Breathing While You Sleep
Poor indoor air quality is a common issue in bedrooms with closed windows and constant air conditioning, especially in humid climates like Singapore.
Your mattress can make this worse. Synthetic materials may release VOCs, trap allergens, or hold moisture that encourages mould.
Natural latex helps by:
Reducing airborne mould spores
Limiting dust mite allergens
Emitting fewer VOCs, which lowers chemical buildup in your bedroom air
Sweat and Humidity Build Up Overnight
Your mattress needs to handle sweat and humidity without breaking down. Natural latex:
Doesn’t absorb moisture
Breathes well even in high humidity
Keeps its shape despite temperature swings
This matters in bedrooms where the air is cool but humidity lingers. These conditions create the perfect environment for mould in materials that trap moisture.
Trapped Heat Can Disrupt Sleep in a Hot Climate
Singapore stays hot year-round, with average temperatures between 26 and 32°C. In these conditions, heat buildup in your mattress can affect how well you sleep.
Natural latex helps by regulating temperature. Its open-cell structure allows air to circulate, so heat doesn’t get trapped while you sleep. Unlike memory foam, it doesn’t retain heat or lose its shape over time, making it a better option for staying cool through the night.
Ready to Sleep Healthier, Every Night?
Most of your week is spent in bed. Choose a mattress that’s actually good for you.
Here’s why natural latex is a healthier choice:
Low in chemical emissions, with no off-gassing
Breathes well in Singapore’s hot, humid climate
Naturally resists mould, dust mites, and allergens
Keeps its shape over time without sagging
Made from renewable rubber trees and fully biodegradable
A quality natural latex mattress usually lasts 10 to 15 years, which makes it a safer long-term investment compared to mattresses that break down faster.
