Step-by-step assembly

Lay 2 posts across the ends of the shelves.
Line up the holes in the posts with the holes in the shelf ends.

Screw the posts to the shelves — 8 screws (144364).
Use the hex key (100001).
Step 4 · manual step 2
Turn the unit over.

Stand the shelf unit upright.
Step 8 · manual step 3
Place the OBSERVATÖR cross-brace on the back.
One eye at each back post.
Step 9 · manual step 3
