How to Get Rid of Smell From New Mattress

There’s nothing quite like the excitement of getting a new mattress. The promise of restful nights and rejuvenated mornings is almost tangible.

How to Get Rid of Smell From New Mattress

However, along with the anticipation, you might notice an unexpected and unpleasant companion: a peculiar smell emanating from your brand-new mattress. This phenomenon, often referred to as “off-gassing,” can be both annoying and concerning.

In this blog post on how to get rid of smell from new mattress, we’ll delve into what causes the smell in new mattresses, why it happens, and most importantly, how you can effectively get rid of it. We’ll guide you through a step-by-step process to ensure your mattress smells fresh, allowing you to enjoy the comfort it promises without any unwelcome odors.

What Causes the Smell in New Mattresses?

Understanding Off-Gassing

Off-gassing occurs when volatile organic compounds (VOCs) are released into the air from new products.

Mattresses, especially those made of foam, are susceptible to this because of the materials used in their production. These VOCs are responsible for the “new mattress smell” that many people find unpleasant.

Common Chemicals Involved

The primary culprits behind the smell are chemicals such as formaldehyde, benzene, and other industrial solvents. These are often found in adhesives, flame retardants, and other synthetic materials used to manufacture mattresses.

While these chemicals are usually present in low amounts, they can produce a strong odor when released over time.

Health Considerations

While the smell is typically not harmful, it can cause mild irritation for some people, such as headaches or respiratory issues. It’s essential to address the odor not just for comfort, but also to ensure a healthy sleeping environment, especially for those with sensitivities.

Why Does It Happen?

Manufacturing Process

Involves Using Various Chemicals

The production process of mattresses involves using various chemicals to enhance durability, comfort, and safety. During the manufacturing stage, these chemicals are trapped within the materials and begin to release when the mattress is removed from its packaging.

Packaging and Shipping

Mattresses are often vacuum-sealed in plastic to make shipping easier and more efficient. This sealing process traps the VOCs inside. Once the packaging is opened, the trapped gases are released into the air, leading to that distinctive “new mattress smell.”

Room Environment

The environment where the mattress is placed also plays a role in the intensity of the smell. Poorly ventilated rooms can trap the VOCs, making the smell linger longer. Ensuring proper airflow can help dissipate these compounds more quickly.

Needed Materials

To tackle the smell effectively, you’ll need the following materials:

Baking Soda:

A natural deodorizer, baking soda is excellent at absorbing and neutralizing odors.


An all-natural cleaning agent, vinegar can help remove stubborn smells.

Fresh Air:

Opening windows and allowing fresh air to circulate can help dissipate the smell more quickly.

10 Step-by-Step Guidelines on How to Get Rid of Smell From New Mattress

Step 1: Unpack the Mattress Immediately

Removing the Plastic Wrap

As soon as your new mattress arrives, unpack it immediately. Removing the plastic wrap and other packaging materials helps the mattress start airing out. Place it in a well-ventilated room to ensure a continuous flow of fresh air. It’s best to do this step outside if possible. The more time you allow the mattress to air out, the better.

Step 2: Use Baking Soda

Baking soda is a natural odor absorber. Sprinkle a generous amount of baking soda evenly over the surface of the mattress. Leave it on for at least 24 hours to let it absorb the VOCs and neutralize the smell.

Then, vacuum it off thoroughly using a brush attachment. You can also mix a small amount of baking soda with water to create a paste and apply it directly to any stubborn areas.

Step 3: Vacuum Thoroughly

After letting the baking soda sit, use a vacuum cleaner to remove it from the mattress. Ensure you vacuum all the crevices and surfaces thoroughly to get rid of any residual baking soda and absorbed odors.

It’s best to use a vacuum cleaner with a HEPA filter to trap any leftover particles effectively. You can also use a handheld vacuum for smaller areas.

Step 4: Apply Essential Oils (Optional)

For an added layer of freshness, consider applying a few drops of essential oils such as lavender, eucalyptus, or tea tree oil. Mix a few drops of water in a spray bottle and lightly mist the surface of the mattress.

This step is optional but can help mask any remaining odors. The essential oils also have antibacterial and antifungal properties, making them great for keeping your mattress clean.

Step 5: Air Out the Mattress

A Room With Good Airflow

Position the mattress near an open window or in a room with good airflow. If possible, use a portable fan or air purifier to help circulate the air around the mattress. This will help speed up the off-gassing process. You can also place the mattress outside in a shaded area for a few hours to air out.

Step 6: Place in Direct Sunlight

Sunlight can naturally break down VOCs. If weather permits, place the mattress outside in direct sunlight for a few hours. Be sure to flip it to expose both sides to the sun’s rays.

If this is not possible, place the mattress near a sunny window to get some indirect sunlight. It may also help to remove any sheets or covers during this step to allow the mattress to air out more thoroughly.

Step 7: Use White Vinegar

White vinegar is another effective odor neutralizer. Fill a spray bottle with equal parts water and white vinegar. Lightly spray the mattress surface and let it dry completely.

The vinegar smell will dissipate, taking the unwanted odors with it. You can also use a mixture of white vinegar and water to clean any stains or spots on the mattress.

Step 8: Set Up Activated Charcoal or Odor-Absorbing Bags

Activated charcoal and odor-absorbing bags are great for continuously capturing any lingering smells. Place them under your bed or near the mattress to keep the air fresh.

The charcoal and bags will need to be replaced every few months. It’s also best to use bags made of natural materials such as bamboo or activated charcoal.

Step 9: Use a Mattress Protector

A high-quality mattress protector acts as a barrier, preventing any new odors from seeping into the mattress.

It also helps protect against spills, dust, and allergens, contributing to a healthier sleeping environment. You can choose from a variety of materials, including cotton, polyester, or waterproof protectors.

Step 10: Regular Maintenance

Vacuum Your Mattress Regularly

To keep your mattress smelling fresh, incorporate regular maintenance into your routine. Rotate and vacuum your mattress regularly, and refresh it with baking soda every few months. The more you take care of your mattress, the less likely it is to develop strong odors.

Following these steps on how to get rid of smell from new mattress can help eliminate the unwanted smell from your new mattress, allowing you to enjoy its comfort without any unpleasant odors. Remember to keep the room well-ventilated and use natural odor-neutralizers for a healthier and more refreshing sleep experience. 

So, don’t let the initial off-gassing damper. You’re getting a good night’s rest on your new mattress. With these simple steps, you can rid your mattress of the smell and enjoy all the benefits it has to offer.  Happy sleeping!

Additional Tips

Improve Room Ventilation

Improving the ventilation in your room can significantly help in reducing the smell faster. Keep windows open whenever possible and use fans to ensure a steady flow of fresh air.

Use Indoor Plants

Certain houseplants, such as spider plants and peace lilies, are known for their air-purifying qualities. Placing these plants in your bedroom can help reduce VOC levels and improve air quality.

Opt for Low-VOC Products

If you’re sensitive to smells or concerned about chemicals, consider purchasing low-VOC or eco-friendly mattresses. These products use fewer harmful chemicals, resulting in less off-gassing.
