Medical grade materials
Eco-friendly & organic materials

Providing a healthy and safe sleeping surface for your child is essential. Our foam is CertiPUR-US certified and offers a liquid-proof cover made of organic fabric.

Trust our certified foam made without any heavy metals, flame retardants or other substances that could harm your little one's health.

The natural fibers of our TENCEL® cover are directly extracted from raw wood, while respecting the environment.

Safe for baby and the planet
Better support for all growth stages

Many companies offer a reversible baby crib mattress with different foam densities. This leads to an uneven sleep surface over time, and can cause body misalignment during important stages of developement.

Our premium hybrid foam is engineered to offer the best possible support, ensuring optimal alignment during all growth stages.

True comfort and support
Waterproof and breathable

Accidents are bound to happen, so we've engineered a waterproof cover thats simple to clean and maintain.

The TENCEL® cover uses organic fibers, making it soft and breathable.

Always dry, and easy to clean
Optimal temperature control

Our hybrid foam uses open cell technology which allows for better airflow than memory foam. When your little one sleeps better, you sleep better.

A cooler sleep
