Why It is Important to Speed up off-gassing?

Prolonged exposure to chemicals and VOCs released during the off-gassing process of a new mattress can have negative effects on your health. These chemicals have been linked to respiratory issues, headaches, dizziness, and even cancer in some cases.

By speeding up the off-gassing process, you reduce the amount of time you and your loved ones are exposed to these potentially harmful chemicals. It’s especially important for those with pre-existing respiratory conditions or compromised immune systems to minimize exposure to these chemicals as much as possible. 

Don’t let the smell of a new mattress compromise your health – take action to minimize exposure to harmful chemicals and enjoy a restful night’s sleep with peace of mind. And speaking of strong off-gassing odors, did you know that certain materials used in mattresses can contribute to a more intense odor? Let’s explore some common causes.

Causes of Strong Off-Gassing Odors

There are several factors that can contribute to a strong off-gassing odor in a new mattress.

Manufacturing Process

The manufacturing process of sustainable mattresses involves using natural materials, such as organic cotton, wool, and latex. These materials are grown without the use of harmful pesticides or chemicals, making them safer both for the environment and for consumers. Once harvested, the materials are treated with non-toxic processes to create layers that will provide comfort and support.

The layers are then assembled using a variety of methods, such as hand-tufting or zipping together. This allows for customization and adjustability in the mattress design. Finally, the mattress is wrapped in an organic cotton cover and shipped directly to customers.

Chemicals Used in the Production of Mattress

Chemicals used in the production of traditional mattresses can be harmful to both the environment and human health. These chemicals, such as formaldehyde and flame retardants, are often added to synthetic materials to increase durability and safety.

However, these chemicals can off-gas over time and release toxic fumes into the air. This process can take weeks or even months, leaving consumers with an unpleasant odor and potential health risks.

How to Speed Up Mattress Off-Gassing: 11 Expert Tips

To speed up the off-gassing process and get a good night’s sleep, here are 11 expert tips:

Air In A Well-Ventilated Room

The quality of air in a room can have a significant impact on your health. Poorly ventilated spaces can trap harmful pollutants such as dust, mold, and carbon monoxide, leading to respiratory problems and other health issues.

On the other hand, a well-ventilated room with fresh air can improve your overall health and well-being. Proper ventilation helps reduce indoor air pollution, keeps humidity levels balanced, and allows for better oxygen flow.

To ensure good air quality in your home, make sure to open windows regularly and use fans or air purifiers to increase circulation. Regular cleaning and maintenance of HVAC systems can also help keep your indoor air clean.

Air Outside In The Sun

To speed up the off-gassing process, take your mattress outside on a sunny day. UV rays from the sun can help break down the VOCs and reduce the odor more quickly than if left indoors.

Be sure to choose a well-ventilated area where your mattress can receive direct sunlight for several hours. Avoid leaving your mattress outside overnight or in damp conditions.

By airing out your new mattress in the sun, you’ll minimize exposure to potentially harmful chemicals and improve indoor air quality faster. So, take advantage of sunny weather and get that off-gassing process moving!

Air Purifier

Another way to speed up the off-gassing process of your new mattress is by using an air purifier. This device can help remove VOCs and other toxins from the air, which in turn helps reduce the chemical odor emitted by your mattress.

Using an air purifier is a safe and effective way to improve indoor air quality while reducing exposure to potentially harmful chemicals, place it in the room where you’re airing out the mattress and run it for 24 hours. The purifier should be able to capture and eliminate most of the VOCs present in the air, making it easier for you to breathe and sleep comfortably.

Baking Soda

Baking soda is a natural and affordable solution for speeding up the off-gassing process of your new mattress. The odor-absorbing properties of baking soda can help eliminate the chemical smell emitted by the mattress.

By using baking soda, you can reduce the amount of time it takes for your new mattress to off-gas, making it easier to sleep comfortably without any unpleasant odors., simply sprinkle it generously over the entire surface of the mattress, and let it sit for at least 30 minutes. Then, vacuum thoroughly to remove any residue. Baking soda is non-toxic and safe for use around children and pets.

Vacuum The Mattress Regularly

Vacuum The Mattress

One of the easiest ways to speed up the off-gassing process of your new mattress is by vacuuming it regularly. Vacuuming helps to remove any toxins or dust trapped in the mattress, which can contribute to the chemical smell.

Make sure to vacuum your mattress at least once a day during the off-gassing period. Use a handheld vacuum or an attachment designed for mattresses to get into all the nooks and crannies.

By vacuuming regularly, you can help reduce the time it takes for your new mattress to off-gas. This will make it easier to breathe and sleep comfortably without any unpleasant odors.

Jump On It

jump on the mattress

If you have a foam or latex mattress, jumping on it can help speed up the off-gassing process. This method is also known as the “white sock treatment.”

Simply jump on every inch of the mattress for as long as possible. This will help to dislodge any trapped chemicals and release them into your well-ventilated room. However, be sure not to try this method with a mattress containing springs as it could lead to damage.

Jumping on your new mattress regularly can help reduce the time it takes for off-gassing to occur. Just make sure to do so in a safe and controlled manner for optimal results.


Dehumidifier in the bedroom

If you’re living in a humid environment, using a dehumidifier can speed up the process of mattress off-gassing. This is because higher humidity levels can cause the chemicals to remain trapped in the material for longer periods.

By using a dehumidifier, you can reduce the moisture content in your room and prevent it from being absorbed by your new mattress. This will help release any unwanted chemical odors into the air more quickly.

Mattress Protector

A mattress protector is a great way to protect your mattress from spills, stains, and allergens. However, it’s important to wait until your new mattress has fully off-gassed before using a protector.

This is because using a protector too soon can trap some of the chemicals in the material for extended periods. The last thing you want is to increase your exposure to toxins and harmful substances.

Once your mattress has fully off-gassed, you can safely use a protector without worrying about any negative effects. It will act as a barrier between you and the surface of the mattress, preventing any unwanted substances from seeping in.

In addition to protecting your mattress, a cover can also help reduce allergies and prevent bed bugs and dust mites from accumulating on your bed. Just make sure to choose one that’s breathable and easy to clean for optimal comfort and hygiene.

Avoid Synthetic Fragrances

Off-gassing can be unpleasant, but many people try to mask the smell with synthetic fragrances. However, using scented candles or air fresheners in the same room as your off-gassing mattress can actually slow down the process.

Synthetic fragrances contain chemicals that can interact with the chemicals being released from your mattress, making it harder for them to disperse. This means that you’ll be exposed to the toxins and harmful substances for a longer period of time.

In order to speed up the off-gassing process, it’s best to avoid using any scented products in the room where your new mattress is located. Instead, open windows and doors to increase ventilation and allow fresh air to circulate.

If you want a pleasant scent in your bedroom, consider using natural alternatives like essential oils or dried flowers. These won’t interfere with the off-gassing process and are less likely to cause adverse reactions or allergies.

Bamboo Charcoal Bags

Bamboo charcoal bags are an excellent way to speed up the off-gassing process of your new mattress. These bags work by absorbing the volatile organic compounds (VOCs) that are released from your mattress, which can help reduce the unpleasant odor. They are non-toxic, eco-friendly, and can be reused many times over. Plus, they’re affordable and easy to find online or at home goods stores.

To use bamboo charcoal bags, simply place them on and around your mattress. They will begin to absorb VOCs immediately and can be left in place for several days or weeks, depending on how strong the off-gassing smell is.

To refresh the bags and release the VOCs they’ve absorbed, simply place them outside in direct sunlight for two hours. This will help to recharge the activated charcoal inside and make them ready to use again.

Follow The Manufacturer's Advice

One of the most important things you can do to speed up the off-gassing process of your new mattress is to follow the manufacturer’s advice. Most mattress manufacturers will have specific guidelines on how to reduce the smell and how long it will take for the off-gassing process to complete.

Make sure to read through any user manuals or instructions that came with your mattress, as they may contain valuable information on how to speed up the process. If you can’t find any guidance, don’t hesitate to contact the company directly for assistance.

Ignoring the manufacturer’s advice could result in a longer off-gassing period or even damage to your mattress. So, it’s essential to follow their recommendations for a safe and efficient way to speed up the off-gassing process.


How Long Does Off-Gassing Last?

The length of time mattress off-gassing lasts depends on the type of mattress you have. Memory foam and synthetic latex mattresses tend to have the longest off-gassing period because they use more chemicals during manufacture. Natural latex mattresses don’t off-gas, while innerspring mattresses are predominantly made of stainless steel springs that don’t off-gas, but their plastic pockets do.

The duration of off-gassing can range from a few days to several weeks or even months. However, the smell should gradually dissipate over time as the chemicals break down and escape into the air.

Although it’s normal for new mattresses to emit an odor during the off-gassing process, it can be unpleasant and cause discomfort for some people. If you’re sensitive to smells, it’s essential to choose a low VOC (volatile organic compound) mattress or allow your new mattress ample time to air out before using it.

Is Mattress Off-Gassing Toxic?

The short answer is no. The low levels of chemicals released during off-gassing are not generally considered toxic. However, they can cause short-term issues for some people, such as headaches, breathing difficulties, dizziness, and allergies.

It’s essential to choose a low VOC (volatile organic compound) mattress if you’re sensitive to smells or have pre-existing health conditions that could be exacerbated by off-gassing. Natural latex mattresses don’t off-gas at all, while innerspring mattresses are predominantly made of stainless steel springs that don’t off-gas but their plastic pockets do.

If you’re concerned about the potential health effects of off-gassing, it’s always best to consult with your doctor or healthcare provider for personalized advice. In general, though, the odors emitted during the off-gassing process should dissipate over time as the chemicals break down and escape into the air.

Who Should Care About Off-Gassing?

Everyone should be aware of off-gassing. Off-gassing refers to the release of chemicals from furniture, paints, and household items into the air we breathe. These chemicals can have negative effects on both our health and the environment. Pregnant women, newborns, and young children are especially vulnerable to these toxins. 

However, even healthy adults can experience symptoms such as headaches, dizziness, and respiratory problems after prolonged exposure to these chemicals. It is essential to always research and choose products with low or no VOC emissions to reduce exposure to these harmful substances.


Mattress off-gassing is not generally considered toxic, but it can cause short-term issues such as headaches, breathing difficulties, dizziness, and allergies. It’s best to choose a low VOC mattress if you’re sensitive to smells or have pre-existing health conditions that could be exacerbated by off-gassing.
