    Firmness

    From a mattress width of 160 cm, the mattress core is always made up of two individual cores. You can choose whether both cores have the same firmness or different firmness levels (e.g. “Medium + Firm”).

    For a size of 180 × 200 cm, this means two 90 cm cores, for example. The cores can either be glued together to form one continuous core or supplied as two separate cores inside a shared cover (see section “Core”).

    Soft corresponds to H1, Medium to H2, and Firm to H3.
    Cover

    Organic cotton

    Cover made from 100% organic cotton (GOTS) with 300g/m² organic cotton (GOTS) quilting, straight quilting – machine washable, vegan.

    Sheep’s wool

    Cover made from 100% organic cotton (GOTS) with 500 g/m² quilting of sheep’s wool (GOTS), wave quilting – temperature and moisture regulating.

    Core

    For mattresses wider than 160 cm, the cores are always made from two individual cores (e.g. 2 × 80 cm). You can choose whether you would like two separate cores in a shared cover or whether you would like us to bond the two cores together to form one continuous core.

    High Quality at a Fair Price

    Koje is our most affordable mattress – featuring a 14 cm synthetic cold foam core, an organic cotton cover and OEKO-TEX certification, offering a fair compromise between ecology and price.

    Choose between two firmness levels: Firm (H3) and Medium (H2). Overall, Koje feels slightly firmer than our natural latex mattresses.

    Komfort Matratzen mit ergonomischen Zonen für deinen Rücken

    Ergonomic and tested for harmful substances

    The cold foam core is OEKO-TEX® Standard 100 certified and has therefore been tested for harmful substances. Its high density of 50 kg/m³ ensures durability and prevents sagging.

    The seven symmetrical zones support the body where it is needed most – firmer around the hips, softer at the shoulders – for even support in every sleeping position and on both sides.

    Care
    • Rotate and, if necessary, flip the mattress every 2–3 months to prevent pressure points and help maintain its shape for as long as possible. Air it out regularly, ideally without a duvet, to allow absorbed moisture to escape. The cotton cover and the lyocell cover are removable and machine-washable at 60 °C. After washing, pull the covers firmly into shape while damp. The wool cover is not washable – please remove stains only locally using water and a sponge.
