Frequently asked questions
How thick should a pack n play mattress be?
Most pack n play mattresses range from 2 to 4 inches thick. A thickness of at least 3 inches is recommended for comfort, but ensure it doesn't compromise safety, mattresses should fit snugly without gaps.
Are thicker mattresses safe for infants?
Yes, as long as the mattress is firm and fits tightly in the play yard. Thicker mattresses can reduce the risk of suffocation if they remain firm. Always check for safety certifications like CertiPUR-US and follow the manufacturer's guidelines.
What certifications should I look for?
Look for CertiPUR-US for foam safety and durability, and OEKO-TEX or Greenguard Gold for low chemical emissions. These ensure the mattress is free from harmful substances.
Can I use a regular crib mattress in a pack n play?
No, pack n play mattresses are smaller and often foldable. Using a regular crib mattress can create dangerous gaps. Always buy a mattress designed for your specific play yard model.
