Many people love their memory foam toppers, but they often smell like chemicals. This smell comes from a process called off-gassing. It happens when volatile organic compounds (VOCs) in the foam break down and release gases. These gases include harmful chemicals like formaldehyde, benzene, and toluene.
At first, the smell can be really strong. But don’t worry, it’s usually not dangerous and goes away in a few weeks. Some brands, like Amerisleep, make their foam in ways that smell less. This means you might not get that strong chemical smell.
Key Takeaways
- Memory foam mattress toppers often emit an initial “chemical-like” smell due to off-gassing of volatile organic compounds (VOCs).
- The smell is generally not harmful to most people and typically lasts up to 4 weeks.
- Some memory foam brands use better materials and production methods to reduce or eliminate the odor.
- Off-gassing happens as VOCs like formaldehyde, benzene, and toluene break down and release gases.
- Proper storage and airing out the topper can help minimize the smell.
Understanding Memory Foam Composition
Understanding the smell of a new memory foam mattress topper starts with knowing what it’s made of. Memory foam is mostly polyurethane, a material from petroleum. To make it better, chemicals are added. These help it feel the body’s heat and pressure.
What Is Memory Foam Made Of?
Memory foam isn’t natural; it’s a polyurethane-based foam made by NASA in the 1960s. To make it work well, chemicals and compounds are added. These can include things to stop fires, kill germs, and even plant oils.
Importance of Chemicals in Production
The chemicals in memory foam are key to its quality and safety. Flame retardants, for example, help it meet safety standards. But these chemicals can also cause the smell of new memory foam. Companies are trying to make safer, less smelly foam by using plant oils.
Knowing how memory foam is made helps you choose the right topper. It also helps you avoid any odor problems.
Reasons for the Initial Smell
When you open a new memory foam mattress topper, you might smell something strong. This smell is called off-gassing. It happens when the topper releases chemicals into the air. The off-gassing process is like the smell from a new paint or car.
Off-Gassing Explained
Off-gassing happens when foam and adhesives in the topper release chemicals. These include things like chlorofluorocarbons (CFCs) and formaldehyde. The smell can be stronger or weaker based on the foam’s density and how it was made.
Common Chemicals Involved
Volatile organic compounds (VOCs) in memory foam can cause bad smells. Being around too many VOCs can hurt your eyes, breathing, and brain. Knowing about off-gassing helps you choose a topper that’s good for your health.
Understanding why your topper smells and what chemicals are involved helps you pick the right one. This way, you can sleep better knowing your topper is safe and comfy.
How Long Does the Smell Last?
When you first open a new memory foam mattress topper, you might smell something. This smell, called off-gassing, comes from the foam’s chemicals. The good news is that it usually goes away in a few days to weeks, depending on some things.
Duration of Off-Gassing
The time it takes for the smell to go away can change a lot. If the smell is really strong, it might take longer to fade. Thicker memory foam takes longer because it has more chemicals.
Factors That Influence Smell Duration
- Foam Density: Thicker foam smells longer, up to weeks.
- Chemical Composition: The chemicals in the foam affect how strong and long the smell lasts.
- Environmental Conditions: Good air, temperature, and humidity help the smell go away faster. It might disappear in days in a well-ventilated place.
Some CertiPUR-US® certified mattress toppers might not smell at all. They’re good for people who don’t like strong smells.
Knowing what affects the smell’s duration helps you make your bed smell better faster. You can enjoy a fresher sleep space sooner.
Factors That Can Intensify Odor
Memory foam mattress toppers are very comfortable. But, they can have a strong smell at first. Some things in the environment can make this smell worse. Knowing what these things are can help reduce the smell.
Temperature and Humidity Effects
The smell from memory foam comes from chemicals that get released. Hot temperatures make these chemicals come out faster. This makes the smell stronger.
Also, when it’s more humid, the smell gets worse. This is because moisture in the air helps the chemicals spread out.
Improper Storage and Transport
How you handle and store memory foam toppers can also affect the smell. Keeping the foam compressed for a long time makes the smell worse. This is true during transport or storage.
Putting the foam in direct sunlight or near heat can also make the smell stronger.
Knowing how these factors can affect the smell helps. You can then take steps to make the smell less noticeable. This way, you can still enjoy the comfort of these toppers.
Tips for Reducing the Smell
If your memory foam mattress topper smells bad, don’t worry. There are ways to get rid of the smell and sleep better.
Airing Out Your Mattress Topper
To ventilate your memory foam mattress topper, let it air out for 48-72 hours. Open windows and turn on fans. This helps get rid of bad smells.
Using Baking Soda to Absorb Odors
- Sprinkle a lot of baking soda for odor removal on your mattress topper.
- Let it sit for a few hours, then vacuum it up well.
- The baking soda will soak up and get rid of bad smells.
You can also use white vinegar mixed with water to clean and freshen your mattress topper. Some people like using essential oil-based air fresheners to cover up smells.
By cleaning and airing out your memory foam mattress topper often, you can stop smells from building up. This makes your sleep area fresher and more comfortable.
How to Choose Low-Odor Options
Memory foam mattress toppers can sometimes smell. But, you can find ones that don’t smell much. Look for low-odor memory foam and CertiPUR-US® certified products. Also, choose brands that don’t smell much.
Looking for CertiPUR-US® Certified Products
The CertiPUR-US® certification is a good sign. It means the foam is safe and doesn’t smell much. It’s tested for harmful chemicals and smells. So, a CertiPUR-US® certified topper is a safe choice.
Brands Known for Minimal Odor
Some brands focus on making toppers that don’t smell. Look for eco-friendly mattress toppers and brands that use natural materials. For example, Amerisleep uses castor oil in their foam. This makes the topper smell less.

Maintaining Your Memory Foam Topper
Keeping your memory foam mattress topper fresh and odor-free is important. Regular cleaning and storage help prevent smells and extend its life. Here are some key tips to keep your memory foam in great shape.
Cleaning Tips to Prevent Smells
To keep your memory foam topper clean, vacuum it often. This removes dust, skin cells, and allergens. Vacuuming monthly is a good rule.
For small stains, use a mild detergent and blot gently. Don’t scrub too hard, as it can harm the foam. Never machine wash it, as it can damage the foam.
Using a mattress protector helps prevent smells. It keeps your topper safe from spills and moisture. For tough stains or odors, try laundry borax and baking soda.
