Nook applies this knowledge in all products by facilitating better airflow in and around the crib and by ensuring smarter temperature regulation at naptime and nighttime.
The disadvantages are that you don't quite get the complete support that memory foam can provide. While they can bend to the shape that you lie in it, it's more 'general' rather then the specific support that memory foam can do. As mentioned above, latex toppers are also quite expensive.
