Key Features

• Size and fit: Measures 38L x 24W x 4H in and is made to fit most mini and portable cribs, so shoppers should measure their crib before ordering.
• Firm support: A hypoallergenic fiber core made from recycled bottles provides a consistently firm sleeping surface that supports safe infant sleep positions.
• Waterproof cover: The durable vinyl cover blocks wetness and wipes clean with warm water and mild soap, helping prevent odor and stains.
• Safety certifications: GREENGUARD Gold certified and tested for flammability, lead, phthalates and CPSIA standards, which reduces concerns about chemical emissions.

Who It's For

The Twinkle Stars mini mattress is ideal for caregivers furnishing a nursery with a mini or portable crib, parents who prioritize a firm, hypoallergenic surface, and anyone who wants a mattress that is simple to clean after leaks or diaper accidents. Its lightweight construction also makes it practical for small spaces, travel between homes, or use in a second sleeping area.

Shoppers who need a mattress for a standard full-size crib, a Pack n Play style playard, or who prefer a plush or memory foam feel should look elsewhere; this mattress is intentionally firm and designed specifically for mini and portable crib dimensions.
