About Length and Width

Please choose the length and width carefully when ordering a custom-size futon.

A futon measuring 210 × 160 cm (82.7 × 63.0 in) is different from a futon measuring 160 × 210 cm (63.0 × 82.7 in). We recommend sleeping along the Length side of the futon.

The center of the futon is padded with more cotton along the length direction. As the futon is used, the cotton gradually settles according to the weight of the body. Sleeping in a different direction may feel less comfortable.

What is GOTS Certification?

GOTS (Global Organic Textile Standard) is one of the world's most rigorous certifications for organic textiles.

The certification verifies that every stage of production—from farming and harvesting to processing, manufacturing, and distribution—meets strict environmental and social responsibility standards.

The use of harmful chemicals is tightly controlled, ensuring a safer and more skin-friendly material you can use with confidence.

Fabric & Colors

The outer fabric is made from GOTS-certified organic cotton and is available in four colors: Natural Beige and three original colors developed for Futon Tokyo.

Natural Beige is used in its unbleached state, so small brown cotton specks may appear on the surface. These are natural parts of the cotton and are not a defect.

The other three colors are original Futon Tokyo colors, developed to complement the simple character of our cotton futons and work naturally in a wide range of interiors.

The same organic cotton fabric is used across all four colors.

Filling

The filling is 100% GOTS-certified organic cotton.

For larger sizes, such as Queen, our craftspeople carefully layer as many as 30 sheets of cotton by hand, gradually shaping the futon as they work.

We use cotton with a firm, supportive fiber that works well for Japanese futons. The futon feels soft at first, then gradually becomes denser and more supportive with use.

No wool, polyester, flame retardants, pesticides, or adhesives are used in the filling.

Size Information

Please check the listed measurements carefully before ordering.

Size names such as “Single” or “Double” can vary by country.

For our Futon Mattresses (Shikifutons), the fabric size and finished size are different. Once the cotton filling is added, the futon becomes thicker, and the finished size is usually about 10 cm (4.0 in) smaller than the fabric size.

Numbers in parentheses indicate the finished size after cotton filling is added.

US Full is available for selected futons only.

Package Size & Weight

Approximate package sizes and weights.

Care Instructions

  • After sleeping, fold back or stand up your futon to let the underside air out. This helps prevent moisture from building up underneath.
  • We recommend using a futon cover to keep your futon clean.
  • Air out your futon regularly to prevent moisture buildup. When possible, dry it in direct sunlight for about 2 hours on each side.
  • If outdoor airing is difficult, place the futon in a well-ventilated room so air can circulate around it.
  • Do not wash with water.
  • For long-term storage, keep it in a dry place, preferably on an upper closet shelf or raised area.

    Please note: If the fabric gets stained, wipe gently with a damp cloth. Avoid beating the futon or jumping on it, as this may damage the cotton filling.

How It’s Made

Each shikibuton is made by the craftspeople in our Tokyo workshop.

From preparing the cotton to layering, shaping, stitching, and tufting, every step is done carefully so the cotton can settle naturally over time.

Futon Mattress (Shikifuton) FAQ

  1. What is a Shikifuton?
    A shikifuton is a traditional Japanese futon mattress used for sleeping. It is usually placed on tatami, a futon mat, or another breathable surface, and can be folded or aired out when needed.
  2. Can I use a shikifuton directly on the floor?
    Yes, but we recommend using it on tatami, a futon mat, or another breathable surface. This helps reduce moisture buildup underneath the futon.
  3. Do I need a tatami mat?
    A tatami mat is not always required, but it is recommended if you use your shikifuton directly on the floor. Tatami helps create a more breathable and comfortable sleeping surface.
  4. Can I use a shikifuton on a bed frame?
    Yes, if the bed frame has good airflow. Slatted bed frames usually work better than solid boards, because cotton bedding needs ventilation.
  5. How thick is a shikifuton when new?
    Our standard shikifuton is over 4 in / 10 cm at the thickest point when new. Cotton futons are very fluffy at first and naturally settle with use.
  6. Will the futon become thinner over time?
    Yes. Cotton futons gradually compress as they are used. A standard shikifuton usually settles to around 2 in / 5 cm over time. This is a natural characteristic of cotton bedding.
  7. Does compression mean the futon is defective?
    No. Natural compression is normal for cotton futons. As the cotton becomes denser, the futon becomes firmer and more supportive.
  8. Is a cotton shikifuton soft or firm?
    It feels soft and fluffy when new, then gradually becomes firmer as the cotton settles. Compared with many modern mattresses, a shikifuton gives a simple, supportive feel.
  9. What should I do if I want a softer sleeping surface?
    If you prefer a softer feel, we recommend adding a futon topper. A topper can add extra comfort while keeping the simple structure of a Japanese futon.
  10. What is the difference between fabric size and finished size?
    The fabric size and finished size are different. After cotton filling is added, the futon becomes thicker and the finished size is usually about 4 in / 10 cm smaller than the fabric size.
  11. How should I choose the right size?
    Please check the actual measurements carefully before ordering. Size names such as “Single” or “Double” can vary depending on the country.
  12. Can I fold and store the shikifuton?
    Yes. A shikifuton can be folded, although larger sizes may be more difficult to handle. Folding also helps air circulate when the futon is not in use.
  13. How often should I air out my futon?
    We recommend airing out your futon regularly to prevent moisture buildup. When possible, dry it in direct sunlight for about 2 hours on each side.
  14. What if I cannot dry it outside?
    If outdoor airing is difficult, stand the futon up in a well-ventilated room. Try to expose the side that was facing the floor so moisture can escape.
  15. Can I wash the shikifuton?
    No. Please do not wash the shikifuton with water. If the fabric gets stained, wipe it gently with a damp cloth.
  16. Should I use a futon cover?
    Yes. We recommend using a futon cover to keep your shikifuton clean. The cover can be removed and washed more easily than the futon itself.
  17. How should I store it for a long time?
    For long-term storage, keep the futon in a dry, well-ventilated place. A higher closet shelf or raised area is recommended to help avoid humidity.
  18. Are flame retardants or adhesives used?
    No flame retardants, insecticides, adhesives, or other residual chemical treatments are added to the cotton filling.
