Components

Backrest (x1)
Armrest (x2)
Seat (x1)
Mechanism (x1)
5 Star Base (x1)
Cylinder (x1)
Casters (x5)

Hardware:

Back Bolt 20mm (x3)
Armrest Bolt 30mm (x2)
Spring Washer (x3)
Flat Washer (x5)
Hex Nut (x2) *pre-installed in armrests
Allen Key 5mm (x1)

Step 1: Assemble the Base

With the 5 Star Base upside-down, push the Casters (x5) into each hole with a fair amount of force (they should 'pop' in). Once completed, turn over so the casters are on the floor and insert the Cylinder into the 5 Star Base with the larger end on the bottom.

Set the assembled base aside for now - we'll get back to it later!

Step 2: Attach Backrest to Mechanism

First, thread each of the Back Bolts (x3) with a Spring Washer (x3) and then a Flat Washer (x3). With the Backrest and Mechanism upside down, slide the backrest into the slot of the Mechanism. Then, using the Allen Key, screw in the middle bolt loosely first to hold the two pieces together, secure the left and right bolts, then return to and tighten the middle bolt.

Use your chair box as a table to help! Place the Mechanism on top of the box while letting the Backrest hang over the side to make it easier to attach both pieces.

Step 3: Attach Seat Assembly to Base

Grab the chair frame that you assembled in Step 2, and insert it into the Cylinder. Push down firmly to secure.

Step 4: Attach Armrests to Seat

With the Seat upside down, insert Armrests (x2) into the sides of the chair, making sure the armrest Adjustment Buttons face the front of the seat (the same direction as the Lock Levers shown above). Next, thread each of the Armrest Bolts (x2) and Flat Washers (x2) into the Pre-inserted Hex Nuts in the Armrests, and tighten.

Step 5: Attach Seat to Chair Frame

Grab the seat you assembled in Step 4. On the right side of the Seat, hold the Seat Depth Adjustment Pull open while sliding the seat onto the chair frame. Ensure the track on the bottom of the seat engages on both sides of the Mechanism. Push the seat all the way back to the base until you hear a click, and release the Pull to secure.

Caution: The seat is only secure once a click is heard when fastening it to the frame.

(Optional) Install Headrest

To install: Attach Headrest to the top rear of the chair back frame. Align the holes on the headrest base to the chair frame, insert both Screws, and tighten with the Allen Key.

All done!

Go ahead, try it out. You may experience what we call an "ahhh" sensation. That's completely normal. You're now well equipped for whatever the workday throws at you.

Now, don't be shy. Show us how it looks!

FAQ & Troubleshooting

Issue	Phase	Suggestion
The armrest bolts don't seem fully tightened.	Assembly	The bolts attaching the armrests to the chair should permit them to slide. Use the locking levers to tighten.
I can't get the seat onto the chair frame.	Assembly	Pull out the square lever on the side of the seat before attempting to slide onto the frame.
My chair won't tilt.	Usage	Make sure to unlock the tilt by twisting the left lever on your chair up.
My chair is stuck in the reclined position.	Usage	If your chair is stuck mid-tilt, recline all the way back until you hear a click. That will reset the tilt lock and your chair back should rise to upright.
The armrests on my chair are wobbling or not stable.	Usage	After you set your preferred armrest width, make sure to lock the armrests using the two levers above the height and tilt adjustment levers. When locked, these levers should be parallel to the seat.
My lumbar support feels uncomfortable.	Usage	Use the two handles on both sides of the lumbar support to adjust it up or down. The lumbar rest is designed to support an upright posture, but if it stays uncomfortable, you can remove it by rotating the pad 90 degrees (without rotating the support arm) and applying firm pressure until it pops off.
