Choosing the right, safe mattress for your baby is important. Our airflow cot mattress is firm, durable and breathable and designed to provide the ultimate cool, comfortable and supportive sleeping space for your baby. This fibre core cot bed mattress has three sleep surfaces: a knitted, mesh zip-off topper and below that a waterproof top panel. The underside is a water-resistant quilted fabric. An anti-microbial treatment reduces the likelihood of allergic reactions to allergens caused by dust mites and pet hair.
