TheChildren's mattress UniversefromTräumelandensures a peaceful and restful sleep. The unique TENCEL ™ cover consists of 32% TENCEL ™ and 68% polyester. The cover is quilted with cozy fleece for an optimal, dry sleeping environment and a pleasantly soft mattress surface. The contained natural fiber TENCEL ™ prevents sweating. The cover is antimony and pollutant-tested, air-permeable, washable at 60 degrees and suitable for the gentle dryer. A side ventilation band ensures even more air permeability. The mattress core consists of high-quality, point-elastic cold foam for optimal lying comfort. Air circulation is improved thanks to vertical air channels. The mattress core has two degrees of firmness, a soft (small wave contour) and a medium firm (large wave contour) - to protect the child's spine. It is recommended to use the medium-strength side from a weight of 35 kg.
