Understanding the Air-Out Process for a New Mattress
When you purchase a new mattress, you might notice a distinctive smell upon unboxing it. This is often due to the release of volatile organic compounds (VOCs) that can emanate from the materials used in the mattress’s construction. Generally, it’s recommended to allow the mattress to air out for at least 24 to 72 hours to ensure that the majority of the noticeable odor dissipates before using it for restful sleep. However, this can vary depending on the type of mattress and the sensitivity of the individual to smells.
What Are Volatile Organic Compounds (VOCs)?
Identifying VOCs in Mattresses
Volatile Organic Compounds, or VOCs, are chemicals that can be emitted as gases from certain solids or liquids – including the foams, adhesives, and fire retardants used in many mattresses. While not all VOCs are harmful, some may cause discomfort or health issues for certain individuals, particularly those with allergies, asthma, or chemical sensitivities.
Sources of VOC Emissions
Mattresses, especially those made of memory foam or other petroleum-based foams, can have a higher level of VOCs due to their manufacturing processes. The scent that comes with a new mattress, often referred to as “new mattress smell,” is actually the result of these compounds off-gassing.
Factors Affecting the Air-Out Time Frame
The time it takes for a new mattress to adequately air out can be influenced by various factors.
The Type of Mattress
Different types of mattresses can have different air-out periods:
– Memory Foam Mattresses: Typically require longer airing due to higher levels of VOCs.
– Latex Mattresses: Latex can also emit a natural smell, which is usually less intense and airs out more quickly than synthetic foams.
– Innerspring Mattresses: These may have less off-gassing than foam mattresses but can still benefit from airing out to remove any smells from packaging or manufacturing.
Manufacturing Processes
Some manufacturers may use a process called “off-gassing” at the factory, which can reduce the amount of air-out time needed once the mattress is in your home. Additionally, certifications such as CertiPUR-US® ensure that the foams meet specific standards for low VOC emissions.
Room Ventilation and Temperature
A well-ventilated room with a moderate temperature can enhance the airing-out process. Warmer temperatures can cause VOCs to be emitted more rapidly, so maintaining a comfortable, not too warm, room temperature can help manage the off-gassing process.
Personal Sensitivity
Individual sensitivity to odors and chemicals can also dictate the length of time a mattress should be aired out. Those who are more sensitive may require a longer time than the average person.
Effective Ways to Air Out Your New Mattress
There are several steps you can take to help your new mattress air out more effectively and efficiently.
Unpack the Mattress Immediately
After bringing your new mattress home, it’s important to remove all of the packaging and let it expand. This initiates the airing-out process and allows for better circulation around the mattress.
Increase Airflow in the Room
Open windows and utilize fans to create a breezy environment that will help carry away the odorous air and introduce fresh air into the room. This step is crucial in speeding up the off-gassing process.
Use a Mattress Protector
Once the initial airing-out period is over, using a breathable mattress protector can help maintain the mattress’ cleanliness without restricting airflow.
Considering Baking Soda
For especially stubborn odors, lightly sprinkling baking soda on the mattress surface and then vacuuming it off after a few hours can help neutralize smells.
Allow Direct Sunlight Exposure
If possible, allowing your mattress to sit in direct sunlight can aid in reducing odors and freshening up the mattress due to the sun’s natural deodorizing effects.
Maintaining Your Mattress for Long-Term Health
The airing-out process is just the beginning of maintaining the freshness and ensuring the longevity of your new mattress.

Vacuuming the mattress regularly and spot-cleaning any stains can help prevent odors from becoming trapped in the mattress.
Rotate or Flip the Mattress
Regularly rotating or flipping the mattress, if applicable, can also promote even wear and extend its lifespan.
Use of a Dehumidifier
In humid climates, a dehumidifier can help maintain a dry environment that’s less conducive to mold and mildew growth in your mattress.
Finishing Thoughts
Airing out a new mattress is an essential step in ensuring your sleeping environment remains pleasant and healthy. While the average time for this process ranges from 24 to 72 hours, individual conditions and sensitivities may require longer. By understanding the off-gassing process and how to effectively manage it, along with maintaining your mattress after the fact, you can enjoy a great night’s sleep on your new mattress with peace of mind.
