About The Sleep System
The 5 little monkeys sleep system has created the ideal sleeping environment for your child. Our system includes a triple-layered mattress made using CertiPUR-US® certified memory foam, waterproof mattress protector and custom fill pillow.
The mattress has cutting-edge temperature regulating technology to keep little bodies comfortable and cozy. The removable and washable mattress cover, made with organic cotton, ensures years of good sleep hygiene. For added protection and comfort, our waterproof mattress protector is made with soft organic jersey knit and comes alongside a custom filled pillow, which is anatomically correct for smaller bodies.
Make Sweet Sleep More Than a Dream
Kids Bedding Designed to Address Issues That Keep Kids From Good Rest

-
Toxin Free & Allergy Proof
Our kids mattress is made from CertiPUR-US® certified foam, and the waterproof mattress protector creates a protective barrier from allergens so kids can breathe easy and rest peacefully. -
Waterproof
Growing up is a contact sport, and kids bedding shouldn't be fragile. Our waterproof, stain-resistant mattress protector and water-resistant mattress cover mean accidents are always what they should be: no big deal. -
Cradling Support
Your child's body is growing, and it needs proper support to get the job done. Our mattress and pillow use a unique cradling technology to reduce restless movement and uncomfortable sleep positions, and the mattress's adaptive pressure relief ensures consistent weight distribution for better skeletal health. -
Temperature Responsive
Seasons change, but this kids mattress will keep your little one comfortable year-round. Our mattress features an open-cell structure to enhance airflow and Dual Phase Change Gel technology that adapts according to a child's unique temperature regulation needs. That means little bodies stay comfortably balanced from head to toe – so your child sleeps soundly through the night whether it's summer, winter, spring, or fall.
