Step-by-step assembly
Step 1
Screw 2 angle brackets (102646) onto the back rail.
Back frame on its back on a rug. 1 screw (109598) each, Phillips screwdriver.
Step 2
Push 2 barrel nuts (100505) into the back legs.
Into the holes on the inside of each leg.
Step 3 · manual step 2
Screw 2 bolts (100159) into them by hand.
Turn the barrel nut with a flat screwdriver so the bolt catches. Leave the bolts sticking out.
Step 4 · manual step 3
Slide the two side rails down onto the bolts.
The oval openings face inwards.
Step 5 · manual step 4
Slide a washer (115983) under each bolt head and tighten.
Allen key (111631). Turn the washer as the small pictures in step 4 show.
Step 6 · manual step 5
Screw 2 angle brackets (102646) onto the front rail.
Front frame on its front. 1 screw (109598) each.
Step 7 · manual step 6
Push 2 barrel nuts (100505) into the front legs.
Into the holes on the inside of each leg.
Step 8 · manual step 6
Screw 2 bolts (100159) into them by hand.
Same as step 2 — leave the bolts sticking out.
Step 9 · manual step 7
Press the front frame down onto the side rails.
Step 10 · manual step 8
Turn the chair upside down onto a table.
The backrest hangs over the edge.
Step 11 · manual step 8
Washers (115983) under the front bolt heads, then tighten.
Allen key (111631). Check the washer direction against the manual.
Step 12 · manual step 8
Stand the chair on a flat floor.
If it rocks, press the seat frame down until all four legs touch (manual p. 7).
Step 13 · manual step 9
Now tighten all 4 bolts with the Allen key.
Check that every washer sits right in its opening.
Step 14 · manual step 10
Seat face-down on the table, then the chair upside down onto it.
The brackets rest on the underside of the seat.
Step 15 · manual step 10
Fix the seat with 4 screws (109598) through the brackets.
Use the Phillips screwdriver — not a power drill.
Step 16
Turn the chair upright.
Your ROSENTORP chair is ready.
Tips & safety
- Does the chair rock? Stand it on a flat floor and press the seat frame down until all four legs touch, then tighten the bolts (manual p. 7).
- Hand tools only. The manual says not to use a power drill for the seat screws (step 10).
- Work on a rug. The manual shows this so the parts don’t get scratched. Unsure about a step? Contact IKEA.
