KEVI Denmark Chair

Purchased 44 years ago as a child's chair, it was used by my children for about 15 years until they grew up.
After that, it was rarely used and has been stored.
The painted wooden parts are relatively clean, but as you can see in the photos, rust is noticeable on the iron parts.
There are no issues with using it as a chair. It's also cute just to have it displayed.
Please judge the condition from the photos.
Seat dimensions: Width 400mm, Depth 330mm. Seat height: 355mm to 460mm.
