The off gassing is incredibly strong initially. You need to have somewhere to put it until it has had chance to air out. It takes weeks for it to go. I have a Tempurpedic bed. It was so strong we had to sleep in the other room for weeks and I kept going in to walk on it to release the fumes. Totally fine now, and I am really really sensitive to things like cleaning sprays etc. so much so I only use vinegar or I get a massive migraine.
Primal, minus eggs, dairy and a myriad of other allergens.
