Tatami also effectively absorbs sweat. Even if you perspire a lot at night, you can wake up feeling dry and fresh since the sponge-like structure not only absorbs moisture but also eliminates odors.

Additionally, the rush releases the moisture it has collected as the air becomes dry, adjusting the humidity, so you may anticipate a moisturizing effect in a location containing rushes.

Modern individuals, however, have stronger curves because they are taller than their forebears.

Because of this, some people use soft mattresses with springs or soft materials like memory foam while they sleep, which may exaggerate their curvature and have a negative impact on their sleep. It’s also true that back discomfort might result from it.

The product “Tatami” is good for effortlessly straightening the contours of your body that have grown too strong and correcting them to natural curves because it is softer than flooring and harder than memory foam.

Just like when sleeping on tatami in a room decorated in the Japanese style, the bedding used on a tatami bed should be folded and stored every day. Do not leave it unattended, please.

  • Turn the tatami surface over and let it dry for three to four days in the shade outside in a well-ventilated place.

Between the futon and the tatami mat, you may absorb extra moisture and stop it from accumulating by using a dehumidifying sheet or slatted mat. An absorbent sheet that removes excess moisture is a dehumidifying sheet. The sheet can be reused numerous times after the moisture has been absorbed. Simply hang the sheet outside to dry. Dehumidifying sheets are known for being portable and lightweight.

8. Is there a recommended number of tatami mats for my bedroom?

In general, a single person’s bedroom should be between 4.5 and 6 tatami mats in size, whereas a bedroom for two couples should be between 6 and 8 tatami mats.

Additionally, you can put a TV and dresser in addition to the bed if you have 10 tatami mats.

9. On tatami mats, will alcohol eradicate mites?

Both dust mites and bacteria are killed by alcohol disinfection, which also has bactericidal properties.
