New mattress odors is a common concern for many people, especially after purchasing a new mattress made from non-natural cushioning products. These materials can release volatile organic compounds as they cure, resulting in noticeable off-putting scents and mild respiratory irritation. While the off-gassing often disappears after a couple of weeks, there are practical measures you can take to accelerate the process safely through proper cleaning and care.

Start by unboxing your new mattress as soon as possible and position it in a drafty room. Ventilate the room with open windows and portable fans to enhance gas dispersion. This simple step helps accelerate the release of VOCs. Avoid covering the mattress with any fabric or barrier materials during the first week. Enable the material to ventilate so the VOCs can escape naturally.

Afterward, coat the mattress uniformly with baking soda. This common household item neutralizes smells and can absorb residual chemical scents. Let it sit for at least four to six hours if possible. Once the time has passed, clean the surface using a a crevice brush suited for fabric. Take your time with each section and make several passes how to clean sofa at home eliminate odor-absorbing particles that may have captured VOCs.

For a deeper clean, lightly clean the top layer with a damp cloth that has been lightly sprayed with white vinegar. White vinegar neutralizes odors and kills bacteria and can help neutralize residual smells. Never saturate the foam—just use a barely damp cloth and dry it thoroughly before use. Wait until no moisture remains before putting on any bedding.

Avoid using harsh chemical cleaners, air fresheners, or perfumed deodorizers. These can react with the materials in the mattress and produce toxic fumes. Instead, focus on natural, breathable solutions. If the smell remains noticeable after 10–14 days, perform another round of deodorizing. It’s also a recommended practice to use a certified organic or breathable mattress protector going forward. This forms a breathable layer between you and the foam while still maintaining breathability.

Lastly, maintain good indoor air quality by adding an activated charcoal-based air cleaner in your bedroom. They effectively trap VOCs and volatile compounds and help reduce lingering contaminants.

Implementing these proven techniques, you can significantly reduce mattress off-gassing and make your bedroom safer and more pleasant. VOC levels typically normalize in under three weeks with consistent effort.
