Nishikawa Keeps Pelvic Support Cushion with Replacement Cover

Comfortable seating that maintains your ideal posture. The Seat Pillow made with bedding technology.

Modern people spend an average of 7 hours sitting each day.
This often leads to poor posture,
causing pain in the lower back and hips.
Keeps, born from Nishikawa's sleep science,
stabilizes the position of the sacrum and ischium,
allowing you to easily maintain your ideal sitting posture.

I purchased this item but kept it stored away, having used it very little.
The color is gray.
It comes with a replacement cover.

The price was ¥11,000 for the cushion
and ¥4,000 for the cover.

It is still in usable condition.
Would anyone who understands used items be interested?
