Buying Guide: How to Choose the Right Thick Pack N Play Mattress
- Size and fit: Verify 38″ x 26″ is exact for your play yard. Look for rounded corners and edge support to minimize gaps that could pose safety risks.

- Durability and weight: Consider weight for portability and a design that can withstand folding and frequent transport.
- Care and cleaning: Check care instructions for both the cover and inner foam. Some require spot cleaning while others are machine washable.
