Sealy Baby Cozy Cool
Score: 81/100
Delta Children Summer Breeze
Score: 84/100Rankings

The Summer Breeze Mattress provides a dual-sided, breathable design with an upcycled Cloud Core and a removable, machine-washable cover, certified GREENGUARD Gold and JPMA. At 12 lb it is heavier and lacks extensive third-party testing. Suitable for health-conscious parents wanting a long-lasting, eco-friendly mattress from birth through age 3.

The Sealy Cozy Cool Hybrid provides a 2-stage mattress with 204 coils and a cool-gel foam side, wrapped in a waterproof breathable cover. Its heavier weight and lack of GREENGUARD certification are notable compromises. It fits parents who want hybrid support and temperature regulation.
