35% bamboo (more breathable) + 65% polyester (softer)
High Quality Material: Our mattress pad is eco-friendly and made from natural, pure bamboo, resulting in a soft and moisture-wicking fabric. It is very breathable, unlike cotton and terry covers, it is also made from bamboo fiber, and does not contain chemicals, which is important for a baby. Our material is 100% comfortable. The thin, soft and stretchy sides of the waterproof protective cover will allow air circulation and access, giving your baby a restful night's sleep.
