A Mattress Designed for Kids


    The unique properties of our CertiPUR-US ® certified memory foam allow it to adapt to your 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. This kids’ mattress contours to the shape of your child’s body to relieve pressure points and promote proper spinal alignment.


    Memory foam is not only hypoallergenic but also antimicrobial due to its inherent properties. Its dense structure and composition make it resistant to common allergens such as dust mites, mold, and pet dander. This inherent resistance helps create a cleaner and healthier sleep environment by minimizing the presence of potential allergens.


    Made from organic cotton, the sleep surface of the mattress cover allows for enhanced airflow and ventilation, promoting a cooler and more breathable sleep environment for your child. The natural properties of organic cotton help regulate body temperature, wick away moisture, and prevent heat buildup, ensuring a refreshing and comfortable night's sleep.


    The mattress cover is designed to be 100% machine washable, allowing for convenient cleaning. You can simply toss it in the washing machine whenever needed. For optimal results, wash the mattress cover on a cold setting and avoid using heat when drying.

Love this so far. Took my toddler a few nights to get used to being in a big bed but now she absolutely loves it. Very comfortable too.

Softest Mattress Ever!

We bought this mattress for my almost 3 year old as he transitioned out of his crib. This bed is so soft and comfortable that I actually kind of look forward to when he needs extra snuggles to fall asleep.


My 13-year-old daughter loves her new bed!

No complaints

The order shipped and delivered quickly. Very easy to unpack. My son loved the monkey surprise. The mattress is comfortable and we highly recommend.
