New memory foam tends to have a slight scent as a result of the production process. No worries, you can easily reduce the scent by tossing the whole pillow in the dryer on low heat for an hour or two with a dryer sheet. If you don’t have a dryer, allow the pillow to air out for a day or two in direct sunlight. Keep in mind that the new foam scent is not harmful, as our foam is CertiPUR-US and GREENGUARD Gold certified for your safety.
