Frequently Asked Questions
Are cooling crib mattress toppers safe for newborns?
Newborns need a firm, flat sleep surface to reduce SIDS risk. Avoid adding soft, loose toppers or layers for infants. If using a dual-sided mattress, use the firm infant side. Any additional topper should be designed specifically for crib safety and must fit snugly with no gaps.
How do cooling features actually help sweaty sleepers?
Cooling gel foam diffuses and spreads heat, breathable cotton/mesh covers wick moisture and allow airflow, and hybrid innersprings promote ventilation. Together these features reduce heat buildup and help babies maintain a more comfortable temperature overnight.
How should I clean and care for a cooling crib mattress or topper?
Use the removable waterproof cover for routine washing per manufacturer instructions. Spot-clean the core only if recommended; avoid soaking foam. Rotate or flip dual-sided mattresses as suggested, and air out new foam products per the brand’s guidance before use.
