Cariboo wool sleep pads are manufactured using 100% pure NZ wool fibre. Using newly developed technology, Cariboo needles individual fibres of wool together to form a firm pad suitable for sleeping newborns. The cover is 100% cotton. This is the most natural sleeping surface available that has many natural benefits for babies. Firstly, no fire retardant chemicals are added because wool is naturally fire retardant. Wool will absorb 3 times its weight in liquid, so moisture is drawn away from the baby which assist with temperature balancing. Its like putting a temperature guage underneath the baby if you pick up your baby and the sleeping pad is damp then there is a high chance you baby is too hot. Natural antibacterial properties are one of the nice benefits of using wool.
Because this is 100% natural you have to care for it carefully. If the mattress is aired daily then normal moisture will expel. If need be, you can spot clean and lay flat to dry. If you need to completely clean then hand wash, do not wring and lay flat to dry. Do not dry in a dryer.
