EcoClassica III – Organic Cotton Dual Zone

Colgate’s EcoClassica III, part of the Cradletyme Naturals collection, is a 6” thick, high-quality, dual-firmness mattress designed with your littlest one in mind. The dual-firmness design provides infants with the firmness they need for safety and proper development and toddlers with the comfort they prefer.

Product Review

I spent months looking for a crib mattress and read hundreds of reviews for different products! My daughter was 8 months old before we purchased a crib for her, so I had lots of time to look around! Here is what I like about this mattress: *Very lightweight - makes sheet changes quick and easy. I just pull it up and set it on the sides of the crib to changes the sheets. *No smell - There is no odor to this mattress, which is great since my baby's face spends a lot of time cheek-to-cheek with this! *Dual sided - I really like this feature. The infant side is VERY firm, and the toddler side is still firm, but comfortable. My baby was used to sleeping in a Graco Pack'n'Play, but she sleeps very soundly on this mattress. *Organic - This mattress is organic and environmentally friendly. That was very important to me in making this purchase.
