The mattress cover made of 100% organic cotton from controlled organic cultivation is breathable, washable up to 40 °C, and suitable for tumble drying on a low heat. It offers excellent sleeping comfort thanks to natural latex. The innovative sandwich construction is optimally adapted to the sleep needs of children. Horizontal and vertical ventilation channels ensure good mattress ventilation. There are two different firmness levels (soft = nubbed structure and medium-firm). Träumeland recommends flipping the mattress to the medium-firm side for body weights of around 35 kg (suitable for body weights up to approximately 70 kg).
