A healthy night's sleep is an important part of your baby's development. This Babybay Mattress, with a height of 5cm, contributes to this. The innovative hygiene cover on the mattress effectively and reliably prevents the penetration of moisture while still allowing air to circulate. You do not need an additional water-repellent topper. This mattress also effectively and sustainably prevents the formation of moulds and dust mites—completely free of harmful substances, without the use of fungicides or microbicides! The patented vertical air conditioning ducts in the comfort foam core ensure increased air circulation and are precisely matched to the ventilation slots on the lying surface. The improved oxygen supply prevents heat build-up. The foam core adapts ideally to the body shape of your little one. The elaborate quilting of the cover offers support and thus ensures a deep, long, relaxing and dreamlike baby sleep. So your baby feels completely at ease. The mattress is harmful substances and awarded "Confidence in Textiles" in accordance with Oeko-Tex Standard 100 class 1 for babies.
