Attach the protective stickers at the points where the chair comes into contact with
the chair. The stickers protect the chair and chair from scratching each other. Use
scissors to cut out portions of the appropriate size, and attach them where the
desk, chair, and other items come into contact with each other.
Attach the stickers to flat surfaces. If a surface is dirty, wipe it clean before
applying the sticker.
Example: Points where chair drawer touches chair

(Adjust the position based on

Okamura Pierna series desks are designed in accordance with JIS school
furniture standards. The desktop can be adjusted to five different heights suitable
for users between JIS size 2 (120 cm height) and JIS size 6 (180 cm height).
The illustration below shows the bolt holes to use for each JIS size when
assembling the desk.
In addition, chairs (sold separately) can be adjusted to five different
heights and depths. Use the height that best suits the height of the user.
