Off-Gassing 101: What You Need to Know About Memory Foam Mattresses

You just got a new memory foam mattress, and as you unbox it, an unusual smell fills the room. It’s the unmistakable "new mattress smell," but what is it really? That odor comes from off-gassing, a process where volatile organic compounds (VOCs) are released into the air. While it’s common, off-gassing raises important health and environmental concerns you should know about. Let’s explore what off-gassing is, why it happens, and how it can affect your health—and introduce safer alternatives for a healthier sleep. What Is Off-Gassing? Off-gassing occurs when certain chemicals in manufactured products release into the air as gases. Memory foam mattresses, made from synthetic materials like polyurethane foam, are a major source of off-gassing. When compressed during shipping, these VOCs become trapped and are released when the product is unpackaged. According to the Environmental Working Group (EWG), these compounds can include formaldehyde, benzene, and toluene—chemicals that are harmful to both human health and indoor air quality. How Off-Gassing Impacts Your Health Respiratory Irritation Breathing in VOCs can irritate the nose, throat, and lungs. The American Lung Association warns that exposure to these chemicals can worsen asthma and other respiratory conditions, particularly in children and older adults. Headaches and Nausea High levels of off-gassing VOCs, especially in poorly ventilated spaces, can cause symptoms like headaches, dizziness, and nausea, as noted by the Centers for Disease Control and Prevention (CDC). Long-Term Health Risks Prolonged exposure to certain VOCs, like formaldehyde, has been linked to more serious health concerns, including cancer, according to the International Agency for Research on Cancer (IARC). How to Minimize Off-Gassing If you own a memory foam mattress, here are some steps to reduce the impact of off-gassing: Unpack Outdoors: Open the mattress in a well-ventilated area, such as outside or in a garage, to allow VOCs to dissipate. Ventilate Your Room: Place the mattress in a well-ventilated room with open windows for several days before use. Use an Air Purifier: A HEPA air purifier can help remove airborne VOCs and improve indoor air quality.
