The arrival of a new mattress is an exciting time. There are plenty of brands that will ship your mattress straight to your door, vacuum sealed, and ready to be opened like a present on Christmas day.

Unboxing and taking your mattress out of its plastic seal should be pretty easy. Most mattresses, especially those with foam layers, may need some time to expand and let foam expand but will be ready to go before long.

Some people may experience chemical-like smell that often accompanies the unboxing of a new mattress, especially foam mattresses. This odor is often referred to as a “new mattress smell” because it resembles the same type of scent people remember from a new car or opening a can of paint.

The new mattress smell is actually s a large group of chemicals, which are found in many products, that are released as gas or “off-gassed” into the air.

When your mattress has been sealed shut and rolled up for a period of time, the chemicals have a chance to build up, making it especially potent when you unbox your new mattress.

So what is off-gassing and should we be concerned for our health? We’ve put together everything you need to know about that new mattress smell, off-gassing and how to remove it from your mattress.

What Is Off-Gassing?

Off-gassing occurs as a result of the breakdown of volatile organic compounds (VOCs). VOCs are emitted gases or vapors from certain solids or liquids.

VOCs can be found in thousands of manufactured household products, from cleaners and air fresheners to paints and dry-cleaned clothes.

Typically, the VOCs from foams and adhesives are the most common ones to off-gas in memory foam mattresses. Some of these include chlorofluorocarbons (CFCs), formaldehyde, benzene, methylene chloride, toluene, trichloroethane, naphthalene, perfluorocarbons.

Mattresses are also required to be flame retardant, and VOCs are used to ensure that as well.

Is Off-Gassing Harmful?

Yes, it is unnerving to think about sleeping on a mattress that is made with chemical carcinogens like formaldehyde and benzene. However, experts say that the low emission levels of these compounds make it OK for us to breathe in each day. What’s more – most major mattress brands that use foam work with an organization that keeps an eye on VOC emission levels (more on that later).

If you choose to research this topic online further, you will see that the discussion about health risks and the use of VOC in manufacturing mattresses is hotly debated. At this time, there are no proven health risks associated with the chemicals used in mattresses. However, the emissions of VOCs are a major concern for air pollution and indoor air quality.

According to the Minnesota Department of Health, breathing low levels of VOCs for long periods of time may increase some people’s risk of health problems. They say that several studies suggest that exposure to VOC’s may make symptoms worse for people with asthma or who are particularly sensitive to chemicals.

How Do I Get Rid Of The New Mattress Smell?

If you have a foam mattress with a strong off-gassing odor, there are a few proactive steps you can take to get rid of the new mattress smell.

Open your mattress and let it air out. The best thing you can do if you are experiencing off-gassing is to let your mattress breathe outside of the house. The majority of VOCs will be emitted in the first hour after opening the mattress but they can continue to be released for an unknown amount of time.

The best way to avoid inhaling off-gas is to open your mattress outside and let it breathe for at least two days. Some suggest letting it air out for a week or two if possible. A well-ventilated area with a cross breeze is a preferable environment for your new mattress.

Consider buying a mattress that has been independently tested CertiPUR-US. CertiPUR-US is a non-profit that makes sure the flexible polyurethane foam on memory foam meets certain environmental and health standards. While they’re not completely chemical or VOC-free, CertiPUR-US certified foams are:

  • Made without ozone depleters
  • Made without PBDEs, TDCPP or TCEP (”Tris”) flame retardants
  • Made without mercury, lead, and other heavy metals
  • Made without formaldehyde
  • Made without phthalates regulated by the Consumer Product Safety Commission Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million)

The Bottom Line

Off-gassing is what happens when the volatile organic compounds (VOCs) in manufactured products like memory foam mattresses break down. It causes a smell that can be unpleasant and disconcerting to others.

Although no health risks have been linked to VOCs and off-gassing, it may be wise to do your research to see what chemicals are in your mattress materials, especially if you have asthma or chemical sensitivities.

If you experience off-gassing with your own mattress, make sure you air it out as long as possible in the most well-ventilated area.
