The two-layer baby mattress Duo offers excellent sleeping comfort thanks to its shape-stable mattress base and a snug topper for added comfort. The breathable cold foam and vertical ventilation channels ensure a perfect sleeping climate. The spine is optimally supported due to the two foam layers. The impact-resistant longitudinal edges provide safety during the first attempts to stand. The functional cover Baby Fresh & Dry (31% cotton / 69% polyester) is a hygienic cover fabric for mattresses. Its material composition provides good climatic and temperature-regulating properties, and it dries particularly quickly. The cover is removable and washable up to 60°C.
