The Linx Baby Easy Breathe Large Cot Mattress provides firm, supportive comfort for babies from birth to 36 months. Made with 80mm high-density foam, full-depth ventilation holes, and a breathable mesh fabric cover, it promotes airflow throughout the mattress while helping reduce heat build-up. It fits snugly into the Linx Baby Trinity and Luan cots and can also be used in compatible cots, travel beds, or independently on the floor.
