Characteristics of Danizerock

Danizerock is a mite-proof bedding that is safe to use because it contains no anti-mite chemicals.

We have obtained a patent for this manufacturing method.
Yamasei’s Anti-Mite Futon is absolutely clean, and contains no mites whatsoever within the inner batting. Our manufacturing technique of preventing the infiltration, during use, of house dust mites via the fabric or needle holes is patented as an Anti-Mite Futon. Since mites are not generated from inside the futon, users are less likely to inhale this often allergenic dust.
We use no anti-mite or other chemicals. So our products are safe to use, even for babies.
We use no anti-mite chemicals such as mite-deterring agents or mite killers in the fabric or the inner batting, so our products are safe to use, even by small children or people with sensitive skin. We especially recommend them for infants, who spend most of their time in bed.
The texture is soft and smooth. Made of 100% cotton featuring outstanding air permeability and moisture-absorption properties.
We use a special high-density woven fabric made of 100% cotton. It has outstanding air permeability and moisture-absorption properties, so it remains nice and dry, without getting moist, even during hot seasons when people perspire while they sleep. During winter, when the temperature drops, our high heat-retaining futons ensure a warm, comfortable sleep. The softness and comfort of our all-natural fabric helps you sleep soundly without being aware that you are sleeping in a unique, highly-functional futon that deters house dust mites.
Our products are easy to care for, too.
There is no need to vacuum the futons to eliminate mites and dust from the inside, which can be quite a chore. Just expose the futon to sunlight on a sunny day, and allow it to dry. The cover can be cleaned at home in your washing machine.

To deter house mites, we worked hard to incorporate all sorts of hidden designs and concepts into our products.

We prevent mites and their eggs from entering the futon.
The fabric is 100% natural cotton. It is specially woven at a high density that prevents the infiltration of both tiny mites, that are only about 0.3 mm across and their eggs. The texture is not too fine, so the fabric has very good air permeability and does not get uncomfortably moist.
Surface of the fabric
  • Fabric used for ordinary futons
    Ordinary futons are made of fabric with large spaces between the weave that allow mites to find their way through easily.

  • Special high-density woven fabric
    Prevents not only mites but also their eggs from entering.

*To prevent mites from creeping in, we eliminated needle holes from the futon surface.
The needle holes made by stitching are a perfect place through which mites penetrate. We adopted a double structure, in which the inner batting is enveloped in an inner fabric pouch. This eliminates needle holes from the quilt. We also designed a special weaving technique using the fabric’s underside. This also prevents mites from entering through stitch holes.
  • Ordinary futons
    Mites can sneak into them at any moment...

  • Special manufacturing technique We allow not a single mite to enter through the stitching.

*There are absolutely no mites inside the futon.
Hand made by skilled craftsmen

Since the manufacturing method that eliminates needle holes cannot be automated, our products are carefully made by skilled craftsmen. The products undergo special high-temperature treatment at the final stage of the manufacturing process, to produce a clean, 100% mite-free futon.

Special high-heat treatment

Treatment using our special high-heat processing equipment is Yamasei’s original method for producing Anti-Mite Futons. Manufacturing methods and treatments such as these that would lower production efficiency are never used for ordinary bedding.

*Our insistence on realizing mite prevention has gained a high reputation
Yamasei’s Anti-Mite Futon series is patented, the first ever for mite-proof beddings. They were developed not only to keep away live mites but also to ward off the tiny fragments of mite feces and dead mites that are inhaled through the nose or mouth, or get stuck to the skin.
We are internationally recognized by hospitals and other medical institutions as a manufacturer specializing in anti-mite futons; our products enjoy a high reputation for their exceptional quality. Articles and papers that describe the effects of our products to help avoid mites on a daily basis? such as the effect of deterring and reducing mites from futons?have been featured in medical journals published both in Japan and overseas.
