No, I suggest you read more about the info provided by the manufacturer.
According to my research there is only latex. The top of the mattress is cotton, the sides and bottom are not cotton. There was no smell when we opened the mattress and we have not had any health problems come up since sleeping on it. It is super hard though. I bought it as a base and have 2 latex toppers on top of it as well as a wool topper. I’m super happy with it with the toppers but it was too hard without.
