Improved airflow and temperature control – thanks to breathable mesh fabric

Open-weave polyester mesh allows air to pass through while the microfiber fill retains structural softness without blocking ventilation. The construction helps maintain a more comfortable microclimate inside the cot.

Hygienic and teething-friendly rail cover – with machine-washable fabric

Fabric and filling are machine washable, with the recommendation to secure all fabric fasteners before laundering to avoid snagging. Materials are designed not to shrink or fade easily.

Removes drool, debris and paint chips from the sleep area easily, keeping the crib cleaner and safer for teething babies.
