I ordered this item because we are in need of a new mattress, but unfortunately cannot afford one at the moment. I read the other reviews and gave this item a shot, and I am truly happy with it. It arrived in 3 business days, unfolded by itself quickly, and we used the foam mattress the same night. There was a slight smell, but nothing annoying where it keeps you up at night. Overall, it is a wonderful purchase and I sleep fantastically now, no more back pains!!
