    Wendematratze aus Kaltschaum

    Two-Sided Mattress

    Koje is our most affordable mattress – made with synthetic cold foam, an organic cotton cover, and Oeko-Tex certification, offering a fair compromise between sustainability and price.

    As a reversible mattress, it offers two firmness levels: firm (H3) and medium (H2). This allows you to find out at home which suits you best. Overall, Koje feels slightly firmer than our natural latex mattresses.

    7 Zonen Kaltschaummatratze

    Ergonomic and tested for harmful substances

    The cold foam core is Ökotex 100 certified and therefore tested for harmful substances. The high density of 50 kg/m³ ensures durability and prevents dimpling.

    The 7 symmetrical zones support the body where it needs it - firmer in the hip area, softer on the shoulders. This keeps the spine straight - in any sleeping position and on both sides.

    Care
    • Turn and, if necessary, rotate the mattress every 2-3 months to avoid pressure points and maintain its shape. Air it regularly, ideally without a duvet, so that absorbed moisture can escape. The cotton cover is removable and can be machine washed at 60 °C - please follow the care instructions.
