I bought these mattresses for my kids' new bunk beds. They had no smell like other memory foam mattresses, no extra shipping costs are just the right height and thickness for the bunks that I bought and they were priced modestly. They are firm, but not so much that they are uncomfortable. My son loves his new bed! My daughter is not old enough yet to enjoy them (only 6 mo. we were just planning ahead!) Overall, I'm very happy with my purchase and would recommend it to others.
