The Sealy Baby Serene Duo-Sleek is a two-stage foam crib mattress with a firmer infant side and a softer toddler side, so it carries a child from the crib through the toddler bed. The fiber foam core is hypoallergenic, the cover is fully waterproof and wipes clean, and an airflow pocket adds breathability without metal vents or zippers. At under 8 pounds it is one of the lightest standard crib mattresses, which makes sheet changes easier than with innerspring models. It meets ASTM crib mattress standards and is GREENGUARD GOLD certified for indoor air quality.

The Sealy Baby Serene Duo-Sleek is a 2-stage crib and toddler mattress made from sustainable fiber foam. It is dual firm: one side is firmer for infants, and the other side is cozier for toddlers. The foam is hypoallergenic and extra durable.
The reinforced pearlized cover is waterproof, tear-resistant, stain-resistant and odor-resistant. An airflow pocket lets the mattress breathe without small metal vents or zippers. The cover wipes clean with a damp cloth.
The mattress fits standard cribs and toddler beds. Its square corner design gives a snug fit in the corners. It weighs less than 8 pounds, which makes changing crib sheets easier.
