4 Best Organic Tatami Mats (Traditional Japanese Style)

A tatami mat is a traditional Japanese floor mat consisting of a firm rectangular core wrapped in a woven rush grass surface, traditionally measuring around 2¼ inches (5.7 cm) thick.

Organic tatami mats are made from natural, biodegradable materials like Igusa rush grass, rice straw, and split bamboo. These sustainable and stylish alternatives to traditional carpets and rugs are becoming increasingly popular among eco-conscious consumers, offering natural fibers, tranquil colors, and an authentic Japanese feel.

But some synthetic mats contain compressed wood fiber board or polystyrene foam cores. They also contain chemicals and flame retardants you don't want in your home.

This guide is for eco-conscious homeowners, yoga practitioners, and anyone interested in traditional Japanese home decor without the chemicals.

Below, I list the best organic tatami mats that offer a sustainable, non-toxic alternative to conventional flooring, which can benefit both your health and the environment.

Our 4 Favorite Tatami Floor Mats

They Say: The tatami core is a combination of coconut hair and a cotton based natural filling makes this CocoMat Tatami extremely lighter (10 kg) and consequently easier to handle. There is no aroma or smell when they come out of the packaging. This combination establishes a pliable surface perfect for Yoga and soft exercise.

We Say: The Luxury Tatami Coco Mat is a coconut-cored tatami that works equally well as a traditional floor covering, a futon base, and a yoga surface. After testing it alongside our pure rush-grass mats, it's the most versatile tatami I've used.

The core combines latex-bonded coconut hair (1.8 cm / 0.7 inches) with a 1 cm (0.4 inch) layer of cotton and linen, finished with Igusa rush grass and a traditional black fabric edge on the long sides, for a total thickness of 2¼ inches (5.7 cm) that matches the classic Japanese specification. At roughly 10 kg (22 lbs) per piece, it's also lighter than equivalent rice-straw mats, which makes repositioning much easier.

There is no aroma when the mat comes out of the packaging, so you can use it straight away rather than airing it for days. The coconut fiber underside also allows moisture to evaporate naturally, so it can sit directly on a hard floor without the damp buildup that often causes mold.

The coconut and linen layer makes the mat noticeably softer underfoot than rush-grass-only options, which is why The Futon Shop markets it specifically for yoga and soft exercise. Mrs. M now uses ours as a permanent yoga mat in her home practice room and says it's just as good as some of the eco-friendly yoga mats we have elsewhere.

It comes in five sizes from Twin (39" x 75" / 99 x 191 cm) to Cal King (72" x 84" / 183 x 213 cm), with larger sizes shipped as two pieces that sit flush together. That's the broadest range in this guide and the main reason it works equally well as a yoga surface, a futon foundation, or a low-profile sleeping platform.

They Say: Create a space with a Japanese mood by simply placing these unit tatami mats on the floor. The mat surface material is made from Japanese (Kyushu)-grown rush grass. Each strand of rush grass is thick, with a thick surface skin and fine fibers, resulting in outstanding elasticity and durability.

We Say: FutonTokyo’s mats are a fantastic way to bring natural comfort and beauty into your home.

They’re constructed with Japanese-grown rush grass and Aomori cypress cotton padding, providing excellent elasticity and durability.

They’re lightweight and come with connector joints, allowing you to purchase multiple mats and customize the size and shape of your layout to fit any space.

The color of the edges of my mat looks different from that of the center, but this is not a sign of a product defect…it’s simply an effect of the natural materials used.

These tatami mats are a fantastic choice for anyone looking to add a touch of Japanese style to their home.

The free U.S. (carbon offset) shipping took under three weeks to reach my door. The mat was securely packaged and arrived 100% undamaged.

Finally, if you’re visiting Japan, FutonTokyo has a physical shop in Tokyo that you should visit!

They Say: Oriental Furniture opened its doors in 1985 as a retail store in Natick, Massachusetts. Since then, we have been providing our customers with unique and handcrafted furniture, decor, and gifts from overseas. It has been our privilege to know and work with many of the same craftsmen and their families for more than 30 years.

We Say: Measuring 2” thick, this Oriental Furniture tatami mat is significantly thicker than average.

The thickness makes this platform mat a perfect choice for supporting furniture.

It’s also an excellent choice if you like the idea of sleeping on a traditional Japanese futon mattress on tatami mats but want that little bit of extra height off the ground.

Its double-strength woven rush grass and moisture barrier backing make it incredibly strong and durable.

This mat has a kiln-dried hard pine frame, which ensures that it has a perfect spring vs. firmness balance that makes it durable and comfortable to use.

In addition to the strong frame, it has a baked dried rice straw fill, which gives off a sweet and distinctive smell.

If 6’ x 3’ (72” x 36") is not right for you, don’t worry. This excellent platform tatami mat is available in five other sizes:

• Euro Full (28.50” x 78.70”)
• Euro Queen (31.50” x 78.70”)
• Euro King (34.50” x 78.70”)
• US Queen (30” x 80”)
• US King (38” x 80”)

It’s beautifully designed in a classic Japanese style that instantly elevates any décor or room setting, making it the perfect choice if you’re looking for an attractive decorative platform that also provides a unique and beautiful flooring solution.

They Say: We use the highest-quality rushes and Japanese traditional methods passed down many years to delicately craft each tatami mat individually. Good futon and good tatami mats for a good sleep. Tatami mats bring the wonderful, calming feeling of being surrounded by nature. Would you like to experience a “Japanese bedroom” using tatami mats and futons?

We Say: The FULI Japanese Tatami Mattress is ideal for giving your bedroom a unique and calming look.

FULI calls it a mattress, but it’s essentially the same as all the other folding tatami mats I tested…just better!

Its 100% Japanese rush grass material ensures that you will get the best quality and maximum comfort when using this mat.

As the rushes are individually crafted, you can be sure of their long-lasting durability too.

With the FULI Japanese Tatami Mattress, you don’t have to worry about sacrificing comfort for style because it offers both!

Tatami Mat: A Brief History

Tatami mats first appeared in the ancient palaces of Japan and were used as a status symbol by the elite.

A tatami mat is made from a combination of Igusa rush grass, rice straw, and split bamboo held together with natural fibers and has been an essential part of Japanese culture since at least the Heian period (794-1185).

Tatami mats are still used today, especially by practitioners of Zen Buddhism, who use them as a meditation platform.

But they're not only for Buddhists. Many households are beginning to see the benefits of having a tatami room in their home.

What Are the Benefits of Using an Organic Tatami Mat?

Organic tatami mats are better for the environment and can offer other benefits, including the following.

• Environmentally Sustainable: The production of tatami mats often involves minimal processing and the use of non-toxic materials, making them a healthier choice for indoor environments compared to synthetic flooring options. They are made from natural, renewable materials like rush grass, rice straw, and split bamboo.
• Biodegradable / Compostable: When tatami mats come to the end of their life, they can be taken apart and composted or used as mulch without damaging the environment.
• Provides Noise Insulation: The dense straw base of organic tatami mats offers better sound absorption and insulation compared to rugs and carpets, which makes them great for bedrooms and nurseries.
• May Help With Back Pain: Tatami offers unique "firm yet springy" resilience, providing better support for the back and joints, and reducing impact on knees when walking barefoot. Firmer sleeping mats can help soothe back pain.
• May Be Suitable for Allergy Sufferers: Tatami mats are often considered a good choice for those with allergies, as the tightly woven rush grass surface may collect less dust than some traditional floor coverings.
• Temperature Control: Organic mats maintain cool surfaces in summer and retain heat in winter, providing superior climate control.
• Provides Natural Antimicrobial Properties: Rush grass is often considered to have natural antimicrobial properties, though the extent of these properties can vary.
• Acts as a Humidifier/Dehumidifier: When humidity levels are high, tatami mats capture and retain moisture from the air. When conditions become drier, they release this stored water vapor back into your home, effectively functioning as both a humidifier and a dehumidifier!
• Can Help With Mental Health: The traditional design and smell of tatami mats are said to bring about inner peace, which can be beneficial for mental health.
• Delivers Unique Aesthetics: Tatami mats look beautiful and bring a traditional Japanese feel to your home.
• Gives a Minimalist Look: Tatami mats fit in well with a minimalist lifestyle.
• Portable and Easy to Store: Some tatami mats are lightweight, practical, and can be folded up for easy storage if you need to move or rearrange your home.

It’s not all positive, though. There are some minor potential downsides to be aware of:

• Easily damaged if not careful
• Prone to mold build-up
• Labor-intensive to keep clean

If you decide the positives outweigh the negatives, there are many ways to use tatami in your home.

What Are the Common Uses for Organic Tatami Mats in A Home?

Organic tatami mats are most commonly used in the following ways:

• Sleeping surface beneath a futon mattress, either on the floor or on a low platform bed
• Yoga and meditation practice, where the firm but pliable surface provides natural cushioning
• Tea ceremony settings, following traditional Japanese custom
• Low-profile floor covering in living rooms, reading nooks, or guest spaces
• Traditional Japanese-style room (washitsu) flooring, often combined with sliding doors and minimal furniture
• Flexible modular flooring, where unit mats can be rearranged or removed as needs change
• Kids' Bedroom floor with a non-toxic bean bag chair on top to create a comfortable seating/play area

Do Organic Tatami Mats Help with Mold or Have a Unique Smell?

Organic tatami mats can help reduce mold risk because the natural rush grass and rice straw or coconut fiber core absorb and release moisture, allowing humidity to evaporate rather than build up.

However, they're not mold-proof. Mats placed directly on cold or damp floors, or in poorly ventilated rooms, can still develop mold underneath.

Choosing a mat with a coconut fiber backing, airing it periodically, and maintaining good room ventilation will keep yours in the best condition.

Tatami mats are known for their distinct and unique smell. This is because the rush grass, rice straw, and split bamboo used to make them give off a natural scent that some find comforting, while others may find it unpleasant.

You can minimize the smell with regular maintenance, such as airing out the mat or using essential oils and incense. You just need to know how to care for your mat properly.

How Do I Care for And Maintain an Organic Tatami Mat?

A tatami mat can last decades with proper care. Some top tips to extend the lifespan include:

• Immediately wipe up all spills with a clean, damp (but not too wet) cloth.
• When vacuuming, always go in the direction of the weaves.
• Always place padding under heavy furniture (always lift furniture to move, never drag).
• You can restore minor dents with a hot towel or steam iron.
• Remove your shoes when walking on a tatami mat.
• Don’t step too close to the edge.
• Avoid placing them in damp areas and keep them dry and well-ventilated.
• If you have to store your mats for an extended period, ensure they’re kept in a cool, dry place (under-bed storage bags will help keep them in A1 condition).
• Putting your mats outside in the shade on a sunny day can help eliminate odors. Just be sure to keep them in the shade because direct sunlight can turn the natural green color yellow.

Don’t Be Fooled by Low Quality Brands

Low-quality, non-authentic mats are often made from inferior materials, leading to a shorter lifespan.

Ensure you only buy genuine sustainable tatami mats if you want the best results.

Investing in authentic products supports local communities and lets you enjoy all the benefits of this traditional flooring for many years to come.

Be careful to avoid greenwashing companies falsely making their mats sound more authentic and eco-friendly than they actually are.

What Is the Difference Between Organic Tatami Mats and Other Floor Mats or Bed Rugs?

Organic tatami mats differ from other floor mats and bed rugs in their construction, firmness, and intended use.

• Traditional tatami has a dense rice straw or coconut fiber core wrapped in woven Igusa rush grass, giving it a firm, supportive surface around 2¼ inches (5.7 cm) thick that can be slept on directly with just a futon.
• Standard floor mats and bed rugs are typically thin, soft, and decorative, designed to sit on top of existing flooring rather than function as a sleeping or sitting surface in their own right.
• Bamboo floor mats are a great option if you’re looking for an alternative. They provide a similar look and feel without needing regular maintenance.

What Are the Different Types and Sizes of Organic Tatami Mats Available?

Traditionally, Japanese tatami mats are usually twice as long as they are wide, with the most common sizing being 910mm x 1,820mm (35.8" x 71.7").

However, this varies slightly in different parts of Japan.

• The most common tatami mat size in Tokyo is 880mm x 1,760mm (34.6" x 69.3")
• The most common tatami mat size in Nagoya is 910mm x 1,820mm (35.8" x 71.7")
• The most common tatami mat size in Kyoto is 955mm x 1,910mm (37.6" x 75.2")

Are There Any Eco-Friendly Certifications for Organic Tatami Mats?

Most genuine tatami mats are made in Japan by artisan craftspeople. Organic certifications are often too expensive for small-scale producers.

Also, many of the certifications we’re familiar with in the U.S. are uncommon in Japan. The recommended mats might not be officially marketed as organic, but they’re jam-packed with non-toxic and sustainable natural materials.

Is Tatami Flooring Easy To Install?

Yes, tatami flooring is effortless to install and can be put in place within minutes.

Can organic tatami mats be used for sleeping directly on the floor?

Tatami mats are suitable for sleeping directly on the floor. Full-thickness mats like the Futon Shop Luxury Tatami Coco Mat are designed for this purpose.

Some people find traditional tatami mats comfortable enough to sleep on (and even find that the natural scent can help them sleep more deeply).

Others prefer an all-natural futon mattress on top of their tatami (which is an alternative to the traditional way of placing a futon mattress on a futon frame).

Where is the Best Place to Use a Tatami Mat?

Tatami mats are perfect for creating a cozy and inviting atmosphere in your home.

They can be used in any room, but Japanese-style tea rooms (chashitsu) are also particularly suited to mats.

What is a Tatami Coco Mat?

It’s a tatami mat with an internal layer of coconut coir for extra stability and durability. The Futon Shop Luxury Tatami Coco Mat is the best example I found.

What’s the Best Half-Size Tatami Mat?

The recommendations in this article come in a range of sizes. If you don’t find something to meet your needs, let me know, and I’ll help you source the exact size you’re looking for.

What is a Tatami Bed?

When people talk about tatami beds, they’re usually simply referring to a futon mattress on a tatami mat.

The Final Word

Traditional tatami mats are a great way to bring a Japanese aesthetic into your home and, if looked after correctly, can last for years. By following the tips in this article, you should be able to keep your mat looking as good as new!

Using original Japanese materials and, wherever possible, traditional production methods, you can ensure your tatami mat will stand the test of time. Make sure to buy from a reliable source so you don’t fall victim to greenwashing tactics or inferior products that won’t last.
