• The chair backrest

• The chair seat pad complete with arms

• The chair base complete with castors

• The gas-operated centre column

• The cover for the centre column.

2. Start by attaching the seat pad to the backrest:

• Locate the area on the seat pad designed to receive the angled metal support of the backrest.

• Using the Allen key, remove the 3 bolts from the backrest.

• Slide the backrest into the seat pad and reattach the bolts in a triangular pattern as shown in Diagram 1. Tighten firmly.
  
  

3. Assemble the castor base:

• Place the castor base on the floor.

• Insert the gas lift into the middle of the base, ensuring the silver part of the column is at the top.

• Cover the column with the telescopic cover.

• Your castor base should look like Diagram 2.
  
  

4. Combine the Parts:

• Carefully lift the seat pad and backrest assembly onto the castor base.

• Ensure the centre column fits into the correct part of the seat pad.

• Push down firmly. Congratulations, your chair is now assembled and ready to use!

Seat Height:

• While seated, find the flat lever on the right side under the seat pad.

• Push the lever up to adjust the seat height. Push up while standing to return the seat to its maximum height.

• Adjust the seat height so your feet rest comfortably on the floor, your knees are slightly lower than your hips, and your hips form a 90-degree angle with your body.
  
  

Seat Slide:

• Locate the flat lever on the left side to control the seat pad depth.

• While seated, push the lever up and slide the seat pad backward and forward to your comfort based on your upper leg length

• Ensure the front edge of the seat is 1-2 cm behind your knees, allowing a gap of two fingers between the seat pad cushion and the back of your knees.
  
  

Armrests: 

• Customise your armrests with four adjustments:

  1. Height: Press the button under each arm pad to adjust the height.

  2. Width: Slide each arm pad left and right.

  3. Depth: Slide each arm pad forward and backward.

  4. Arm Angle: Twist each arm pad to angle it in or out.

• Set the armrests so they’re level with your desk, letting your forearms rest parallel to the floor without pressure on your wrists and elbows.
  
  

Lumbar Support:

• Adjust the lumbar support up or down to fit the natural curve of your lower spine, ensuring maximum support.
  
  

Backrest:

• While seated, use the round lever on the left under the seat to lock and unlock the recline. Twist forward to lock and backward to unlock.

• Find your perfect recline position and adjust the tension with the round control on the right. Choose from four tension settings by twisting forward to increase and backward to decrease.
