Inhibits the growth of several types of bacteria, antibacterial processing. Antibacterial effect lasts even after 100 washes.

This is an unused NOMOS medical-grade futon mattress pad. I purchased it from Royal Japan.
It cost just under ￥10,000 before the consumption tax increase, but I believe it would cost over ￥10,000 now.

I originally bought two futon mattress pads. I use one myself, but this one is unused and new, so I am selling it.

NOMOS is a high-performance antibacterial processed fabric developed by Shikibo Co., Ltd., which has a growth inhibitory effect on a very wide range of bacteria.

Key Features of NOMOS Processing:
Broad-Spectrum Antibacterial Action:
It is effective not only against Staphylococcus aureus but also against many bacteria that adversely affect the human body, such as MRSA (Methicillin-resistant Staphylococcus aureus), E. coli (including O-157), Pseudomonas aeruginosa, Salmonella, and Klebsiella pneumoniae.
Mechanism of Action:
The antibacterial agent coating the fibers destroys the bacterial cell wall and penetrates it, killing the bacteria.
Suppresses Odors from Indoor Drying:
It also suppresses the growth of odor-causing bacteria, which is beneficial as it prevents unpleasant odors from developing even when clothes are dried indoors.
High Safety and Durability:
It has obtained the SEK mark certified by the Japan Textile Evaluation Technology Council, and its high effectiveness is maintained even after hundreds of repeated home or industrial washings.

Main Applications:
This processing is used in environments with strict hygiene management, for household items where cleanliness is desired, and for medical and nursing care products: hospital sheets, pajamas, nightgowns.
Food factories: chef's whites.

Product Background and Features:
High-Quality Materials: Royal Japan often handles healthy bedding and high-quality household textile products. Their higher-priced items are characterized by the luxurious use of NOMOS fabric, which offers a powerful antibacterial effect (equivalent to the SEK red mark) suitable for hospital and nursing care settings, going beyond simple antibacterial properties.
Durability: Due to its high cost, it is designed to be durable, with its antibacterial effect barely diminishing even after 100 repeated home washings.
Regarding the Purchase at the Time:
Royal Japan (especially related companies based in Fukuoka) sometimes sells high-quality bedding through exhibitions, door-to-door sales, or specific channels.
Price at the Time: While a typical cover might cost a few thousand yen, a price of just under ￥10,000 suggests added value from the special functional properties (NOMOS processing), the quality of the fabric itself (such as extra-long staple cotton), and meticulous domestic sewing.

The last photo shows that even a regular futon mattress pad is quite expensive! Considering that, my item is definitely of better quality and cheaper!
