Hi odhora89,
Hopefully some of the members here will see your post and share their comments and preferences but in the meantime post #2 here and the topics it links to has much more information about mattresses and children and choosing materials that are “safe enough” for children and includes a number of links to the better forum posts and topics about mattress and children as well including 5 links to topics about crib mattresses that can help you decide on a crib mattress that is the best “match” for you based on your budget and all the other criteria that are most important to you.
