No, pack n plays require a specific size mattress (typically 27.25" x 39.5"). A regular crib mattress is too large and could pose a suffocation risk. Always use a mattress designed for your playard model.
Yes, when they meet safety standards like being firm, flat, and breathable. Look for certifications like CertiPUR-US and GREENGUARD Gold. Avoid soft or plush mattresses for infants under 12 months.
Replace if there's visible sagging, stains that can't be cleaned, or if the cover is torn. Most manufacturers recommend replacing after 2-3 years of use, especially if the mattress was used for siblings.
No, toppers are not recommended as they can increase suffocation risk. The mattress should remain firm and flat. If you need more comfort, consider a higher-quality mattress instead.
