New Mattress Smell: What is it and how to get rid of it?

If you’ve just bought a new mattress, you may be wondering what that strange smell is. Don’t worry, it’s normal! All new mattresses have a certain smell to them that comes out when they are first unpacked, and this process is called off-gassing.

This is caused by the release of volatile organic compounds (VOCs) from the mattress materials. In most cases, the smell will dissipate within a few days or weeks.

However, if you’re finding the smell to be too strong or persistent, there are some things you can do to reduce it. Keep reading for our tips on how to get rid of that bad new mattress smell!

Why Does My New Mattress Smell?

All new mattresses have a certain type of smell, and generally it shouldn’t cause any type of concern. Sometimes the smell is mild, but other times it can be quite strong and pungent. The primary cause of that new mattress smell is Off-Gassing. 

The smell comes from the chemicals used in manufacturing. These chemicals can have a negative impact on indoor air quality and can cause respiratory irritation and other health problems.

How Long Will The Mattress Smell Last?

Generally, the new mattress smell typically dissipates within a few days, but in some cases, it may take up to a week for the off-gassing to stop completely. The type of materials used in the mattress can also affect how long the odor lasts.

You should look for a new mattress that uses CertiPUR certified memory foam inside.

This means that the foams used are free from harmful chemicals, CFCs, or added phthalates, which is means that there is lower emissions for better indoor air quality. 

Also having CeritPUR foam inside mattresses means that there is safe, non-toxic levels of fire retardants.

For example, the Simba Hybrid and Nectar Memory Foam mattress use CertiPUR® foam during the manufacturing process. 

Another alternative is to purchase a mattress that uses natural materials inside, such as wool, cotton, and mohair for example. The Flaxby Natural Mattress collection from Dreams is a great option to consider.

2. Use a Fan to Get Rid Of the Smell

One easy way to get rid of the new mattress smell is by using a fan. Place the fan near the mattress and let it run for a few hours to help circulate air and dissipate the odor faster.

3. Make Sure There Is Proper Ventilation

Make sure that your room has proper ventilation so that the off-gassing fumes can easily escape and not linger. Keep windows open and turn on a fan to help circulate air in the room. This can also help to reduce the smell faster.

4. Don’t Unwrap the Mattress in A Room That Doesn’t Have Good Ventilation

If possible, it’s best to unwrap your new mattress in a well-ventilated area, such as an open garage or outside. This will prevent the fumes from getting trapped in a small space and allow them to dissipate faster.

Are These New Mattress Smells Dangerous? Should I Be Worried?

While the off-gassing fumes can have a negative impact on indoor air quality and may cause respiratory irritation, they are not typically considered to be dangerous.

However, individuals with sensitivities or respiratory issues may want to take extra precautions in reducing the new mattress smell. It can also affect your quality of sleep.

It’s always best to consult with your doctor if you have any concerns about the potential health effects of the unpleasant smell.

Do All Mattresses Smell Nowadays?

No, not all mattresses will have a new mattress smell. It depends on the type of mattress and the materials used in the manufacturing process, and how much off-gassing occurs.

Some companies may also use methods to reduce or eliminate off-gassing during the manufacturing process.

Mattresses that use memory foam usually smell more as compared to pocket spring mattresses as the foam has more chemicals used in its production process.

It’s always best to do research and choose a mattress that you think will be comfortable for you and your family. 


Getting rid of the new mattress smell can be a hassle, but it is possible with some effort and proper knowledge. It’s also important to consider the potential off-gassing when purchasing a new mattress and choose one that may have less odor.

At the end of the day, if you don’t want to put in the effort to get rid of the new mattress smell, then the best thing you can do is look for mattresses that have CertiPUR certification.

Mattresses that are CertiPUR certified use less (or no) volatile organic compounds in their manufacturing process and have less off-gassing. 

Also, consider buying a new mattress that comes with trial period of 100 up to 365 days. This way you test the mattress at home, and if for some reason you’re unsatisfied you can return it for a full refund.
