From The Manufacturer

Serta’s Tranquility Comfort Crib and Toddler Mattress is designed with all the features you’d hope to find in your child’s first mattress: Finished square corners to help with a secure fit inside the crib. Lightweight, two-sided construction so your child can use the same mattress as a newborn and toddler. For your newborn, the firmer ‘newborn’ side faces up and then as your child becomes a toddler, simply flip the mattress over to the ‘toddler’ side. The toddler side has a layer of Cool Action™ Gel Memory Foam that provides toddlers with support and the cooling touch of gel. This comfortable crib mattress is also GREENGUARD Gold certified – meeting the strictest standards offered by the GREENGUARD Environmental Institute.
