YappyKids expert team offers a 100% natural mattress. It is made from some of the most exclusive ecological materials currently available. The mattress has multiple layers that provide excellent comfort and the necessary firmness for the baby to develop and grow healthy. At the core of the mattress are two thick layers - each approximately 3 cm - of horsehair and coir. These provide the mattress with a firm shape, as well as the necessary elasticity and resilience. Horsehair creates a perfect microclimate and ensures comfort in various temperatures. It also has quick-drying properties, which are particularly important for children's mattresses. Coir maintains a good microclimate and provides good air permeability. It is quiet - when the baby moves in bed - there will be no unnecessary noise that could wake them up. These two layers are wrapped in a cover - on one side camel wool, on the other - cotton. Camel wool has good thermoregulation - it will ensure a good sleep both in hot and cold weather. Cotton is a highly breathable material, so the body sweats less. The mattress cover is made of bamboo. It surprises with its unbeatable softness. Bamboo has natural antibacterial elements in its fibers, which prevent bacteria from multiplying.
