This is the Tokyu Sports Oasis "Nagara Pelvic Chair Smart." It's a floor chair type that allows you to exercise "while doing other things" in your daily life. It's designed to perform stretching and core training simultaneously. The brown color makes it easy to blend in with various interiors. There are no noticeable scratches or stains, and it's in relatively good condition, but there are some marks like scuffs on the back of the seat. [Color] Brown系 (Brown-based) [Uses] Pelvic support, posture correction Please refrain from purchasing if you are sensitive to used items. Thank you.
