How to speed up mattress off-gassing?


Off-gassing is a common concern when purchasing a new mattress. It refers to the release of volatile organic compounds (VOCs) from the materials used in the mattress manufacturing process. These VOCs can emit a distinct odor, which can be bothersome for some individuals. If you are looking to speed up the off-gassing process and minimize the odor, there are several steps you can take. In this article, we will explore various methods to help you speed up mattress off-gassing.

Allow Sufficient Time

Patience: The first and most important step in speeding up mattress off-gassing is to allow sufficient time for the process to occur naturally. Most mattresses require a period of time to release the VOCs and eliminate the odor. This process can take anywhere from a few days to a few weeks, depending on the specific mattress and the materials used. It is essential to be patient and give your mattress enough time to off-gas before using it.

Proper Ventilation

Airflow: Providing proper ventilation to your mattress can help speed up the off-gassing process. Place the mattress in a well-ventilated room with windows open or fans running to promote airflow. This will help the VOCs dissipate more quickly, reducing the odor. If possible, you can also place the mattress outside in a shaded area on a sunny day to allow for natural ventilation.

Temperature and Humidity

Temperature: Temperature can also play a role in accelerating off-gassing. Higher temperatures can cause VOCs to evaporate more rapidly. If the weather permits, you can increase the temperature in the room where the mattress is placed. However, be cautious not to expose the mattress to extreme heat, as it may damage the materials.

Humidity: Similarly, humidity levels can affect off-gassing. Low humidity can slow down the process, while higher humidity can help VOCs dissipate more quickly. If you live in a dry climate, you can use a humidifier to increase the humidity in the room. However, ensure that the humidity level remains within a comfortable range to avoid any adverse effects.

Natural Remedies

Baking Soda: Baking soda is known for its ability to absorb odors. Sprinkling a generous amount of baking soda on the mattress and leaving it for a few hours can help absorb the VOCs and reduce the off-gassing odor. Afterward, vacuum the mattress to remove the baking soda residue.

Activated Charcoal: Activated charcoal is another natural remedy that can help absorb odors. Place small bowls filled with activated charcoal near the mattress to absorb the VOCs. Replace the charcoal regularly to maintain its effectiveness.


In conclusion, off-gassing is a natural process that occurs when you purchase a new mattress. While it may be bothersome, there are several steps you can take to speed up the off-gassing process. Allowing sufficient time, providing proper ventilation, adjusting temperature and humidity levels, and using natural remedies like baking soda and activated charcoal can help minimize the off-gassing odor. Remember to be patient and give your mattress the time it needs to off-gas before using it.
