Why choose a futon mattress?
A futon mattress is an excellent choice for those who prefer a firm mattress. Compared to a traditional mattress, a Japanese mattress is often thinner and firmer, ensuring your body is well supported while you sleep. This can contribute to a better sleeping posture thanks to the natural alignment of the spine.
In addition, futon mattresses are versatile in use. They can be used on a futon bed, a slatted base or a traditional tatami matMany people choose to buy a futon when they want to create a minimalist bedroom or when they are looking for a flexible mattress that is easy to move. Thanks to these characteristics, a Japanese mattress is not only comfortable but also practical for smaller spaces, studios, or guest rooms.
Additionally, we offer futon protectors and toppers with which you offer your futon mattress extra protection and can easily adjust the sleeping comfort.

Futon mattress fillings
An important feature of a futon mattress is its natural filling. Many futon mattresses are made from materials such as cotton, wool, or coconut fiber. These materials are breathable, moisture-regulating, and contribute to a healthy sleeping environment. In our collection, you will find two main types:
- Traditional futonsThese consist primarily of multiple layers of cotton and offer a firm and authentic Japanese sleeping experience. This Japanese mattress is often used on a tatami mat and can be folded in half. Only a thin version up to 8 cm thick is truly rollable; we make these to order.
- Hybrid futonsModern futon mattresses combine cotton with materials such as latex or foam. This results in a slightly softer mattress with extra support and comfort, while retaining a traditional appearance. Furthermore, many futon mattresses are produced using natural or organically responsible materials, making them a sustainable choice.
Which filling suits you?
| Type | Material | Lying sensation | Suitable for |
| Traditional | Multiple layers of cotton | Sturdy, authentic | For those who love a firm surface and the classic tatami feel |
| Hybrid | Cotton + latex or foam | Softer, resilient | For those who want to combine sturdiness with extra comfort |
| Organic | Cotton, wool or coconut fiber (naturally certified) | Breathable, natural | For those who want to sleep consciously and sustainably |
Futon mattresses from Karup Design

Buying a futon mattress: what to look for?
You choose a futon mattress based on thickness, filling, and the surface on which it will lie. That is how our collection is structured.
Thickness and strength
Our futons are 10 to 18 cm thick: thicker than a traditional Japanese futon, so they are also comfortable on a slatted base or futon bed. Karup Basic (10 cm) and One Traditional mode (13 cm) are the most compact and sturdy; Comfort (13 cm) and Coconut (15 cm) are slightly more crowded; Sandwich (17 cm) and Double en Triple Latex (18 cm) have a latex core and are the most resilient. Our organic futons They are 12 cm thick, the organic Traditional 15 cm.
Filling and lying comfort
Cotton is the foundation of every futon: firm, breathable, and it molds to your body over time. Coconut fiber makes the futon firmer and more breathable. Wool insulates and regulates moisture: warm in winter, cool in summer. Natural latex provides resilience and pressure distribution, comfortable for side and stomach sleepers. Karup Basic and Comfort feature a comfort foam core (4 and 6 cm) between the cotton layers.
Organic or Karup?
Our organic futons are handmade in Germany from GOTS-certified materials, free from chemicals, and made to order. The Karup futons are available in natural or black and fit perfectly on the Karup futon beds.
Substrate
A futon rests on a slatted base, a futon bed, tatami mats or on the floor. Do not place it on a sealed floor without airing it regularly: cotton absorbs moisture and needs to dry. The futon breathes best on tatami; this is also how it is used in Japan.
Rollable or foldable?
Our standard futons are 10 to 18 cm thick and are not rolled up; you fold them in half to air them out, move them, or store them temporarily. If you want a truly rollable futon, like the Japanese shikibuton, we can make that for you. on order: traditional, 100% cotton or wool, maximum 8 cm thick. A futon protector or topper keeps moisture and dirt out of the cotton layers and extends the lifespan. If in doubt, read our extensive futon advice.

Frequently asked questions about futon mattresses
What is a futon mattress?
A futon mattress is a Japanese-inspired mattress, usually constructed from multiple layers of cotton and sometimes supplemented with wool, coconut fiber, latex, or foam. It is thinner and firmer than a traditional mattress and is often used on a tatami mat, slatted base, or futon bed. Read more about what a futon mattress is in our blog article.
Is a futon mattress rollable?
A thin, traditional futon made of 100% cotton or wool up to 8 cm thick is possible; we make those to order. Our standard futons of 10 to 18 cm are not rolled up; you fold them in half to air them out, move them, or store them.
What is the difference between a Japanese mattress and a regular mattress?
A Japanese mattress is generally thinner, firmer, and made of natural materials such as cotton, wool, or coconut fiber. A traditional mattress is often thicker and contains more foam or inner springs. A futon mattress provides firm, natural support for your body.
On what surface do you use a futon mattress?
You can use a futon mattress on a tatami mat, a slatted base, or a futon bed. It is versatile and easily adapts to various sleeping situations, from a permanent bedroom to a temporary guest room.
Is a futon mattress hard?
Firm, not hard. A futon does not sag like a soft mattress, but the cotton molds to your body. If you want more resilience, choose a futon with a latex core (Sandwich, Double, or Triple Latex) or place a topper on top.
Is sleeping on a futon good for your back?
A futon provides flat, firm support: your spine remains straight and your weight is distributed evenly. Many people with back problems find this comfortable. However, choose a sufficient thickness (our futons are 10 to 18 cm) and consult a doctor or physiotherapist if symptoms persist.
How long does a futon mattress last?
On average 5 to 10 years, depending on filling and maintenance. Cotton becomes more compact and firm over the years; latex and coconut retain their resilience longer. Air the futon regularly, rotate it every few months, and use a futon protector. That way, it will last the longest.
