Do Latex Mattresses Smell?
Natural latex can have a characteristic rubber-like smell when new. That is different from using the term “off-gassing” broadly for volatile compounds from synthetic foams or adhesives.
What to do
Follow the manufacturer setup instructions and ventilate the room if a new-mattress odor bothers you. If you have respiratory symptoms or a known latex allergy, seek medical guidance rather than relying on a mattress article.
