Watch Out For

mediumThe waterproof cover is 'wipe clean' only, which can be inconvenient for major leaks.
lowSome users report a slight off-gassing smell initially, though less than cheaper mattresses.

Community Q&A

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.

Compared To

vs Moonlight Slumber Little Dreamer

Moonlight Slumber is noted as a firm, high-quality foam alternative, but Sealy Cozy Cool offers the cooling feature and coil support.

vs Graco Premium Foam

Graco is cheaper but lacks the 2-stage and cooling features; Sealy is preferred for long-term use.

Source Threads

  • 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.
