breathability done right

Breathable crib mattresses are all about added comfort and safety. Simply put, babies tend to cry more when they’re uncomfortable. Airflow under the baby allows heat to dissipate more efficiently, helping regulate temperature for less sweaty backs. According to airflow tests, breathability may also increase safety by allowing air to flow more freely around the baby.

How it works

The breathable cover features a soft organic cotton surface and a 3-dimensional polyester lattice structure that allows air to flow through the fabric and under the baby for 360° air circulation. Since air is able to pass freely through the cover’s 3D structure, babies can breathe right through it!

Practical design

The breathable function is encapsulated in a washable cover that completely hugs the mattress.  In the event of an accident, remove the soiled cover and wipe the mattress clean. Replace with a spare cover or put the baby back to sleep on the fully functional underlying mattress. The cover can then be machine washed and dried at your convenience.

2-stage dual firmness provides a firmer side for infants and a medium-firm side for growing toddlers. As your child develops, switching over is as easy as flipping the mattress.


Firm support

The Organic Breathable Ultra 2-Stage follows CPSC and pediatrician recommendations for firm support and a snug fit so your baby gets the firm, flat surface that’s recommended for safer sleep. It also features strong edges to help prevent limbs from getting caught between the mattress and the crib while providing that extra edge support for toddlers who like to jump!
