The doomoo basics highly absorbent sheet and mattress cover is perfect for babies and also for children who are in the process of becoming dry at night, or who have problems with bed-wetting. It is a completely waterproof padded cover allowing maximum airflow and consisting of 5 different layers. It is highly absorbent and can cope with +/- 2 litres per m 2. The unique way in which it is made actually allows a very large quantity of liquid to be absorbed right through to the bottom layers, thus leaving the top layer dry. Very practical; it is placed directly on top of the fitted sheet and can therefore be changed quickly.
