Children release a lot of moisture through breathing and skin when they sleep. Therefore, opt for a mattress made of breathable and sweat-wicking material and avoid mattresses with plastic covers. If your child suffers from dust mite allergy or if you simply want an allergy-friendly and sustainable mattress for your child, choose a health mattress that is produced with the aim of minimizing environmental impact throughout the product's lifespan. For our ECO Dream and ECO Comfort bed series, we recommend mattresses that are 9 cm high. For our ECO Luxury and DELUXE bed series, we recommend mattresses that are 12 cm high.
