Step-by-step assembly

Step 1
Lay the seat face down on a rug.
Work on a soft surface so the seat doesn’t get scratched.

Push 4 dowels (128995) into the seat.

The rails are marked C — see the manual, step 2.

Step 4 · manual step 3

Two through the top rail of each end frame.

Step 16 · manual step 11
Push 4 cross dowels (113153) into the rails.
Turn them with a flat screwdriver so the hole lines up.
