Nishikawa Air SI Regular Semi-Single Sheet Set - 1 Month Old, Newly Purchased
Product Details
Purchase date: Mid-October 2025.
Purchased at a Nishikawa [AiR] retailer within a department store in Tokyo.
I bought this thinking it would help with my injured back, and used it for a total of about 10 days while seeing how it felt.
Unfortunately, it did not suit my body, so I hope someone who needs it can use it.
The purchase price was:
Mattress body: ¥132,000
Dedicated fitted sheet: ¥8,800
Total: ¥140,800
Firmness: Regular
Size: Width 80cm x Length 195cm x Thickness 9cm
- There are some minor scuffs on the outside of the mattress cover (see 5th photo). The mattress itself has no scratches.
- I do not see any other significant dirt or scratches.
- It was used directly on the floor (the slatted bed shown in the photo arrived very recently and was placed on top for the photo).
- No pets, non-smoking household.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
