Unboxing the Herman Miller Aeron Classic Chair
Your Herman Miller Aeron Classic chair will arrive at your doorstep partially disassembled-the backrest detached. You will find the main body of the chair, the backrest, an Allen key, and screws in a plastic wallet inside the box. Carefully unpack all components and place them on a clean, flat surface.


How your chair arrives: the main body and the backrest, each wrapped and packed in the box.
- Positioning the Backrest: Place the chair body on any stable surface and position the backrest such that the screw holes are aligned with the ones on the chair frame.
- Inserting the Screws: Take the screws from the plastic wallet and insert them into the holes. There should be four in total, two on each side.
2) Using the Provided Allen Key
- Proper Use of the Allen Key: Place the Allen key into the head of each screw.
- Screws: Tightening With the Allen key properly placed in each screw head, rotate it clockwise until such time as each screw is tightened. Make sure the screws are snug but do not overtighten, which may strip the heads of the screws.
- Stability: When all four screws are tightened, gently shake the backrest to make sure it is attached to the body of the chair.
- All Screws Are Well Screwed: Make sure that all screws are tightened.
- Checking Stability: Sit in the chair and feel if the backrest feels right.
- Adjusting Settings: Adjust settings of height, tilt, and lumbar support as preferred.
