Our Karup traditional futon mattress is a 13 cm thick Japanese futon filled with cotton. Our futons have a higher density and thickness than traditional Japanese futons, but it still offers all the great features of a traditional futon. The traditional futon feels flexible and gets its hardness from the surface it rests on, which ensures a medium hard sleeping comfort. Because this futon gets its hardness from the surface, this futon is best placed on a flat surface, such as when using tatami mats. The cotton layers make the futon flexible so that it easily adapts to your body and supports where necessary.

The Karup futon mattress traditional is a futon as a futon is meant, constructed in a traditional Japanese way. Thanks to the multiple layers of recycled cotton, covered with a 100% cotton cover, this futon offers very good ventilation. Recycled Cotton is endorsed by various studies as the most sustainable shape of cotton due to the fact that the high environmental impact caused by regular cotton cultivation does not apply.

Karup futon mattress TRADITIONAL black


  • Ticking of 100% cotton
  • Filling 8 layers of cotton
  • Ecologically recycled cotton through use
  • Felt padding made of wool
  • Thickness 13 cm


  • A futon provides a firm surface with a light counter-pressure and, thanks to the compact cotton filling, forms to the contours of your body. It provides support over the entire length of your body.
  • This is why FUTONS are especially recommended for people with back problems or who are overweight.
  • Due to the natural and airy filling, it offers excellent ventilation. This way you will sleep comfortably even on warm nights.
  • Thanks to the firm structure and the mattress is easy to turn, the FUTON can ventilate well during the day, which means that it is better ventilated and retains its fresh, natural scent.
  • A futon can easily be folded in half, with which you can save space in a smart way


  • A natural property of cotton is its ability to be compressed. To restore the original shape of the futon, it is best to roll and fold it at least once a week in all directions, so that you move the cotton well over the mattress. Cotton is a natural product and can shrink during use with a margin of 1 to 1 cm. To keep the mattress even, you can occasionally run down the edges of the futon with your full weight to keep the surface even.
  • Do not use synthetic corner sheets or flannel/mattress protector, as this will block the ventilation and cause the futon to mold.
  • A futon mattress is made of cotton fibers – don't let it get wet.
  • As with other mattresses, the FUTON must be turned regularly so that it retains its shape and can be ventilated.
  • Leave the mattress uncovered regularly during the day. It can ventilate better if not covered.
  • Provide a ventilating surface, for example a tatami mat or slatted base. Directly on a wooden floor / tile floor / laminate floor or carpet does not provide sufficient ventilation, which can cause the futon to mold.
  • Do not let the futon get wet and do not place it in a room with high humidity. This will result in mold in the futon.
