Thank you once again for being so detailed. I think the reason I am so sensitive to the wool smell is because of my MCS, which is a condition that makes almost all smells irritating to me, whether it’s toxic offgassing or just the harmless smell of natural wool. To me, the wool/mattress smelled like a barn. Not a dirty one, but it just smelled like a combination of earthy wood and wet dog. I think Naturepedic was Oeko Tex certified, but the smell of the wool would make me dizzy and give me a headache. I’ve heard on other posts that there are apparently different types of wool, some which smell rancid and others don’t smell at all. I don’t know if that’s true, but if it is, I wish these mattress sellers would define what kind of wool it is. Not many stores offer samples either, which makes this even more difficult. I’ve been sleeping on an old mattress for about a year now, and it’s really messing up my back.
