  • Cooling Comfort: Perforated Cooling Gel Memory Foam cradles your body while keeping you cool and comfortable all night long. Our Cooling Gel Memory Foam also works to reduce motion throughout the night for a truly restful night’s sleep.
  • Maximum Support: High-density base foam reduces pressure points while providing the ideal balance of comfort and support. Trundle mattress is designed to work with 14-slat Maxtrix twin trundle beds to offer superior support without needing a Bunkie board or box spring.
  • Made for Kids: Medium-firm twin-size trundle mattress is designed to promote proper spinal alignment and distribute weight evenly. The combination of our soft Cooling Gel Memory Foam and high-density base foam is perfect for growing kids.
  • Perfect for Bunks & Lofts: Low-profile design provides the comfort and support of a thicker mattress without the bulk.
  • Breathable Cotton Cover: Mattress cover is made with organic cotton for a soft, plush feel. The breathable mattress cover is easy to remove and machine washable for a clean and fresh sleeping space every time.
  • Safe & Eco-Friendly: Hypoallergenic, non-toxic and CertiPUR-US® certified, our mattresses are made without the use of formaldehyde, mercury or other harmful chemicals or heavy metals. Mattress liner contains blends of cotton for a safe, fire-retardant design without the use of fiberglass or chemicals.


This twin-size trundle mattress is compressed and shipped in one box for an easy setup. We recommend letting the mattress air out and reshape for 24 hours before use.
