1. LA Baby Natural Triple Zone Crib Mattress

This is a fairly nice and moderately priced organic crib mattress to keep in mind. It has quite a few features that are worth mentioning.


The LA Baby Natural Triple Zone Crib Mattress is a dual-sided mattress. This means that it has one side which is super firm, thus ideal for babies, and the other side being softer, thus being ideal for toddlers. It features a CertiPUR-US Certified soy foam core, which is both durable and sustainable, plus it helps provide a baby with good spinal support for a comfortable and healthy sleep.

The LA Baby Natural Triple Zone Crib Mattress also has a memory foam layer on the toddler side for a bit of added softness. It comes with air vents for ventilation and breathability.

This mattress comes with a heavy-duty inner spring system for even more support.

This is a very simple yet effective eco-friendly and organic mattress for your baby and your toddler to sleep on. It is a bit pricey, but well worth it in our opinion.


The Colgate Eco Classica III Eco-Friendlier Crib mattress is another dual firmness mattress. This means that one side is made to be super firm, which is necessary for babies due to breathing safety and spinal support. The other side of the mattress, the side for toddlers, is a bit softer, and therefore more comfortable. It’s a good 2 in 1 choice for babies who are transitioning into the toddler stage. The mattress itself is lightweight, and therefore easy to handle, plus it is a full 6 inches thick as well.

The Colgate Eco Classica III Eco-Friendlier Crib mattress, the baby side, is made with oil-based eco-foam, which is eco-friendly, but still firm and supportive. What is also important to note here is that this mattress comes with a flammability layer to prevent burning and reduce flammability.

Even better is the natural and organic cotton cover. This helps to provide some softness and comfort, plus it is also moisture resistant. It is not totally waterproof, but at least it is moisture resistant.

This is very important when it comes to safe breathing, especially for babies with breathing issues.

This is one of the safest and most natural crib mattresses available right now.
