Step-by-step assembly

Step 1
Screw the 2 casters (10054612) onto the bottom of the armrest.
Stand the armrest upside down. 2 screws (108443) per caster.

Step 2
Lay the armrest on its side and screw in 2 threaded rods by hand.
Threaded rods 10047226 go into the inner side of the armrest.

Step 3
Screw 2 threaded rods (10047226) into the backrest panel.
Lay the panel flat, inner side up. Turn them in by hand.

Step 4
Lower the seat frame onto the 2 rods, standing on its edge.
Springs facing you, as in the manual.

Step 5 · manual step 4
Fit a washer (100854) and a nut (100712) on each rod.
Tighten with the spanner (110470).

Step 6 · manual step 5
Screw the 4 legs (147786) into the base and stick on the felt pads.
The base lies upside down.

Step 7 · manual step 5
Turn the base over onto its legs.

Step 8 · manual step 6
Slide the armrest onto the 2 rods in the side of the seat frame.
The rods go through the 2 openings in the fabric — see the info box in step 6.

Step 9 · manual step 7
Fix the bracket (10100764) with 2 bolts (105102).
One into the backrest, one into the armrest. Use 105102 here — not 122692.

Step 10 · manual step 8
Fit a washer and a nut on the 2 armrest rods.
Inside the seat frame. Tighten with the spanner (110470).

Step 11 · manual step 9
Flip the 2 brackets on the bed rod up.
They stand upright at the left end of the base.

Step 12 · manual step 10
Hold the left armrest against the 2 brackets.

Step 13 · manual step 10
Fix it with 4 bolts (122692) — 2 in each bracket.
Tighten with the Allen key (10095216).

Step 14 · manual step 11
Tip the seat unit forward onto the base — 2 people.
Push the 6 tabs on the front edge down into the gap — see the info box in step 11.

Step 15 · manual step 12
Lift the right armrest a little and push the unit to the left.
Until it sits tight against the left armrest — see the manual, step 12.

Step 16 · manual step 13
Place the 2 back cushions against the backrest.
Tips & safety
- Work with 2 people Tip the seat unit onto the base together (step 11).
- Armrest on the other side? Pages 16–25 of the manual show the mirror version: the bed rod is moved to the other end first.
- Making the bed Take off the back cushions, roll the unit out and fold down the armrest — see pages 26–28 of the manual.
