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

The Sleep System
  • 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.

What the Experts Think

"When it comes to the transition from crib to big kid bed–the better the tools, the smoother the journey. 5 Little Monkeys is one of the most indispensable tools you can have as you head out."
"As a Family Sleep Specialist, I know the importance of a quality sleep surface for a child. Up until finding the 5 Little Monkeys Sleep System, I did not have a specific mattress I could recommend to my clients looking to purchase their child’s first big kid bed mattress. All of the mattresses available were adult mattresses being sold for children. The 5 Little Monkeys Sleep System is unique in that it was developed specifically for a child’s growing body. The creators, veterans in the mattress business, constructed the mattress with the developmentally appropriate support, durability, temperature regulation, and organic materials, for a children’s mattress. As an added value, the mattress also comes with a waterproof and washable mattress protector (priceless for those “accidents do happen” nights), a child size pillow, and an adorable stuffed monkey that the kids will love. I work with so many families during the crib to bed transition, which is often a stressful time. I am so happy that I now have the perfect mattress system to recommend to my clients."
"Children need a good mattress and cozy sleep space as much as any adult. I recommend 5 Little Monkeys. Once your child is ready for a “big kid” bed, get them one that even you would want to sleep in...and maybe you won’t have to!"
