My boyfriend is a diesel mechanic. He works all day around chemicals and the smells don’t bother him. He has sleep apnea pretty bad, so a good friend of ours bought us a new mattress and adjustable frame. A Cloud Supreme. We love it. We were told by an ex employee of mattress firm that we should walk all over it to break the membrane in the material and that will speed up and get through the beginning off gassing period. So we did that last night. We haven’t noticed ANY smell at all from the mattress, and we sleep great… but this is day 2 and both days he’s woken up with a headache. I figure well go two weeks and see if his headaches bed would you recommend to match the softness of a cloud supreme? We have a split side adjustable bed.
