Our tatami mats are manufactured in Fukuyama, Japan. Our craftsmen use
traditional rice straw and igusa rush with traditional hand-sewn fabric
edging. You will never find any non-natural foam, insulation, or latex in our mats.  Note that we do put a waterproof vapor barrier on the bottom of the mats to protect against excess humidity.

Of course! Sleeping on tatami mats is good for your back and your
posture, although it takes some getting used to if you normally sleep on
a mattress. You can sleep directly on the mat with just a pillow, or
you can get a tatami futon to place on your tatami mat(s).

If you use a futon mattress on the tatami mats, we recommend airing/flipping the mattress once per month.

Tatami mats are very durable and strong but need to be taken care of.
Because the top of the tatami mats are made of igusa rushes, they can be damaged by sharp or heavy objects. It is recommended to put pads under furniture feet and to walk in shoes without sharp heels (perfect for sock feet or bare feet!).

Even though tatami mats are often used in a minimalist-style setting, you will often find low tables, cushions, and futon mattresses in tatami rooms.

Our tatami mats last 15 years with proper care.

Use a dry cloth to pick up a wet spill. Use a damp cloth to clean a mess. If residue is present gently use a toothbrush to loosen particles.

Yes. Some people like to put the tatami on a rug to keep the mat from shifting. There is also a vapor barrier on the underside of the mat to protect it.

There are a few approaches you can take if the standard mats do not exactly fill the space you have:

- Put them in the center of the space that you have. Because tatami are
heavy, they will remain in one spot if you put them directly on the floor or on a carpet. They may shift slightly as you use them but they are easy to move back again.

- You can put a small edge, up to 5.5cm tall, to hold the mats in place in the area that is decided upon. For example you could use a standard "quarter round" moulding to give your mats a finished look and keep them where you want them.

- Some people build a section of raised flooring, the same height as the tatami mats (5.5cm), to fill the space not filled by the tatami mats. This can also be a very elegant solution.

Nowadays, the main rule is that there are no rules - anything goes with the placement of tatami mats - it is about practicality and what seems visually pleasing to you!

For example an interesting design is to use half mats only, with the direction of the weave of the top of the tatami alternating to vary the way that light reflects on them.

Historically, different regions and eras in Japan developed different rules for the placement of tatami. For example some say not to let 4 corners of tatami meet in one spot but others recommend this! Others say to never use more than one half tatami in a given layout.

But the main message is to do what works for you in your space.
