Is the Sealy Cozy Cool mattress really waterproof?

Yes, but the cover is water-resistant and wipeable, not fully submersible. A separate waterproof protector is recommended.

Does the mattress sleep hot?

The cooling gel and breathable cotton cover help regulate temperature, but some parents still use a breathable mattress pad.

Positive recommendation for Sealy Cozy Cool dual firmness and fit
We have the Sealy Cozy Cool 2-stage and love it. The infant side is perfectly firm and the toddler side is comfy. Fits our crib like a glove.

Detailed comparison including Sealy Cozy Cool cooling and price
After researching forever, we went with the Sealy Cozy Cool. Main reasons: the cooling gel for toddler side and the better edge support. It's pricier than Graco, but we plan to use it for 3+ years.

Discussion of Sealy Cozy Cool vs. Moonlight Slumber
We have the Sealy Cozy Cool 2-stage and it's great. Moonlight Slumber is also good but all-foam. Sealy has the coils and cooling layer. Worth the extra $ for us.

Praise for Sealy Cozy Cool's safety certs and ease of use
Got the Sealy Cozy Cool. Love that it's Greenguard Gold and the cover is wipeable. It's heavy though, but that's because of the coils.
