Frequently Asked Questions
How firm should a pack 'n play mattress be for safe naps?
A safe nap surface is firm and flat enough to resist significant indenting. Firmness reduces the risk of a baby’s face sinking into the mattress; for infants prioritize a firmer core and avoid very plush, soft toppers. For older toddlers, a slightly thicker, cushioned topper can be acceptable if it still fits snugly and doesn’t compress deeply.
Do I need a waterproof mattress or just a cover?
A waterproof inner liner or waterproof mattress protects the foam from urine and spit-up and prevents mold and bacterial growth. A removable, machine-washable outer cover plus an inner waterproof layer is the easiest and most hygienic approach: it keeps the foam dry while allowing frequent washing of the outer fabric.
Will a thicker mattress increase suffocation risk?
Thickness itself isn’t the sole risk—softness and fit matter more. A thick mattress that’s still firm and fits the playard snugly without gaps can be safe for older babies and toddlers. But very soft, plush cores on a thick topper can increase risk for small infants. Always ensure a snug fit, firm surface, and follow manufacturer age and weight recommendations.
