We ordered this mattress for our child’s room. We opened the box outside on the screened in porch and let it breathe for about 1.5 days.  It filled up nicely and never really had that strong of a chemical smell. Our child loves it and so do we. I’ve fallen asleep on it after reading books at bedtime. Very comfortable. If you like a medium/soft mattress, this is for you. We love it so much that we’re ordering a second for our oldest.
