My husband and I purchased two of the same mattresses. One for our bed and one for our daughter. We love them. Our daughter’s mattress seems a little softer than ours but both are VERY firm. We enjoy the firmness as we hate sinking down in a mattress. Both inflated to a little under 10 inches and they had no smell. No complaints whatsoever from our daughter who is 12 so that’s a plus. I did purchase two mattress toppers for additional comfort. I would definitely purchase these again.
