I was impressed with this Graco Ultra-Premium 2-in-1 Crib Mattress, but more importantly, my little one seemed to like it as well! I admit I was dubious at this innovative concept of two different sides/softness in one mattress to adapt at the child grows, but I think Graco was able to pull it off! The mattress was thick, plush, and comfortable. We have been using it for a few weeks, and it definitely seemed to help my baby sleep better! I can see how it would provide the appropriate level of support and comfort as he grows! The mattress arrived compressed in its cardboard box, but inflated to its full size after a few hours. It appears well-built, high quality, and durable—I don’t doubt that it would last for years usable for future children.
