Any mattresses made with petroleum-based foams, memory foams, chemical adhesives and chemical flame retardants will "off-gas" — which means that they release Volatile Organic Compounds (VOCs) as they age.
However, we do not use polyurethane foams, memory foams, chemical flame retardants or chemical adhesives between the comfort layers of our mattresses. Instead, we use 100% GOLS organic certified Dunlop latex, 100% GOTS organic certified wool, and 100% GOTS organic certifed cotton. These materials are GREENGUARD Gold certified for low emissions and quality assurance by UL Environment.
In particularly humid climates, you may notice a very slight natural odor when your mattress arrives, which will dissipate quickly. This is because your mattress has been sealed after it was made in order to facilitate shipping. This is natural and not a chemical odor.
