Built to Grow With Your Child

Ages 2-7 Side: Soft, Cushioned Comfort
A 1” layer of quilt foam sits right under the cover for a plush, gentle feel. It’s made for lighter bodies and a smooth move from the crib or toddler bed to a big-kid bed.

Ages 8+ Side: Supportive Memory Foam
When they’re ready, flip to the 8+ side. A 1” layer of CopperFlex™ Memory Foam contours to growing frames and eases pressure on shoulders and hips, while the coils underneath keep the spine supported and aligned.

Cool, Bouncy Support on Both Sides
Both sides rest on the same 6” Ascension® individually encased coils, which add bounce, stand up to big-kid wear and keep air flowing. The GlacioTex™ Cooling Cover feels cool to the touch, so kids who run hot sleep soundly.

Certified Safe, Designed in Arizona
The foams are CertiPUR-US® certified, and the mattress is GREENGUARD Gold certified for low chemical emissions. It’s designed and assembled in our Phoenix factory and backed by a 365-night sleep trial and a limited lifetime warranty.

Frequently Asked Questions

What is a dual-sided kids mattress?

A dual-sided kids mattress has a different feel on each side. The Cool Kids Mattress has a soft quilt foam side for ages 2–7 and a supportive CopperFlex™ Memory Foam side for ages 8 and up, so you flip it as your child grows.

When should I flip the Cool Kids Mattress to the 8+ side?

Most families flip it around age 8. If your child seems to need more support sooner, or complains of sore shoulders or hips, it may be time to switch earlier

Is the Cool Kids Mattress good for kids who sleep hot?

Yes. The GlacioTex™ Cooling Cover feels cool to the touch and helps draw heat away, while the 6" Ascension® coil core lets air flow through the mattress. Together they make it a strong cooling mattress for hot-sleeping kids.

Is the Cool Kids Mattress a hybrid?

Yes. It pairs a 6" Ascension® coil support core with a 1" foam comfort layer on each side, giving kids the bounce of coils and the comfort of foam.
