A supporting mattress with springs offers long-lasting comfort and support. The springs feature a felt layer for added comfort, while the dent- resistant orthopaedic foam ensures the mattress stays more comfortable for longer. This extends the life of the mattress and gives you more value for money over time. 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 well-being. This mattress have two covers. The outer cover is removable and machine washable at 60°C. The inner 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.
