[Manufacturer's Suggested Retail Price: ¥18,990]

This popular balance chair naturally straightens your back just by sitting, helping you maintain an ideal, correct posture. It's highly recommended not only for children's studies but also for adults working remotely or using PCs.
This model comes with a support cushion (2nd level) that can be easily attached and detached with Velcro, allowing even small children (height 110cm~) to achieve correct posture without strain. As your child grows, you can remove one cushion to continue using it for adults (up to 180cm tall) for a long time.

[Product Condition]
- There are signs of use on the seat, including food stains and overall fuzziness (fluffiness) due to attachment/detachment of Velcro and friction. We have carefully cleaned and de-pilled the item at home for this listing.
If you use a cover, the stains and fuzziness on the main body will be completely hidden, and you can use it immediately as a beautiful chair with a calm atmosphere.
- The wooden frame and base have minor scratches and small dents from daily use. Additionally, there are small chips (cracks) on the corners of the plywood under the seat. Both are on the underside or near the legs, so they are not noticeable during normal use and do not affect strength or safety.
- One fixing screw on the underside of the seat is missing. In our household, it was still stable and securely fixed without it, but if you are concerned, please purchase a screw from a home improvement store.

Please check the photos for the condition.

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.
