A foam mattress built specifically for a cot. The Airwave Cotbed mattress has a breathable foam core to help keep the mattress (and the infant) cool by increasing airflow through the mattress. The dual-layer Airwave system is designed specifically to provide two separate comfort levels. This product comes with a removable, moisture repellant, zipped cover that can easily be removed and cleaned - to account for the inevitable mess. The mattress is 10cm deep, which provides a supportive, comfortable sleeping surface for your child to use - as recommended by the National Childbirth Trust.
