A firm and supportive mattress with individual springs housed in separate fabric pockets. The springs work independently to offer support for your little one where needed. In designing this mattress we have considered the safety of the child. Current research indicates that the sleeping environment, and in particular its hygiene, is an important factor for the child's future wellbeing. This mattress has two covers: the outer cover is removable and machine washable at 60°C. The extra Innercare™ cover makes removing and replacing the outer cover quick and simple and can be used when the outer cover is in the wash. So in the middle of the night when you and your baby want to get back to sleep after a night time accident, the inner cover provides a suitable waterproof surface if the outer cover has had to be removed. This mattress has a 3D fabric on one side. This fabric promotes air circulation and assists breathability. It also draws fluid away from baby's body for comfort and safety. The bottom of the outer cover is made from a waterproof yet vapour-permeable fabric, excellent for the older child when toilet training, and which significantly reduces sweating. The inner cover is made from a non-sweat water- repellent fabric, helping your little one stay comfortable throughout the night. Before opening the packaging please check the size of your mattress. Optimise baby's sleep by partnering your purchase with a mattress protector from our comprehensive range.
