This Sealy Waterproof Standard Crib Mattress is made up of 150 coils that have been tested for firmness. Because of these steel coils, the surface uniformly distributes your baby's weight, preventing sagging in the middle. When your child reaches the age of one, you can switch the firm side of the crib mattress to the softer (but still supportive) side. The waterproof cover on the baby bed prevents liquids from accessing the core.

Over 5,900 Wayfair customers rated the Sealy Waterproof Standard Crib Mattress five stars, praising its support and long-lasting design. "Excellent baby mattress! I was a little hesitant about getting a crib mattress online, but it worked beautifully and lasted a long time with not one, but two kids sleeping on it for about two and a half years each.", according to one customer.

This non-toxic crib mattress meets all of the following requirements: It is GreenGuard Gold Approved and GOTS certified, has two sides that can grow with your child, and has a hard surface. The main drawback is that Avocado Organic Crib Mattress does not include a waterproof cover; however, you can add this organic crib mattress covering to your order for an extra $59.
