The bed came before the delivery due date and we let it air out for 3 days as said. My husband was a little nervous about the purchase at first as he is not on the skinny side. Believe me this is a really firm mattress. We have had the bed for a week now and it is just now starting to break in. Now that it is starting to become a little flexible it is the most comfortable mattress I have slept on. It doesn't stink, it doesn't get hot, and I don't have any horrible springs in my back which is a plus since I am 81/2 months pregnant. Thanks Overstock!
