The Snuzpod4 is known for being one of the most sleek, safe and snuggly bedside cribs on the market, and one of its key features is improved breathability. This is because of their new ComfortAir Breathable System and liner. This liner is not a cot bumper, it is made from breathable mesh and is designed to allow air to circulate in multiple directions. It has been thoroughly tried and tested and complies with regulations and safety standards.  The liner has surface-level air flow vents which allow air to pass through the crib at the level where your baby is resting. The breathable mesh liner can be easily removed with a zip and machine washed to keep it clean and fresh.
