ATLAS Pro Assembly & Adjustment Guide

Thank you for your purchase of an ATLAS Pro Ergonomic Chair
Follow these steps to unbox, assemble, and adjust your new chair to perfection.

1. Unbox Your Chair: Open the box and check for these parts:

• The chair backrest

• The chair seat pad complete with arms

• The chair base complete with castors

• The gas-operated centre column

• An Allen key 

2. Assemble the Seat Pad and Backrest:

• Find the area on the seat pad that receives 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 them firmly.

3. Set Up 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.

• 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. Your chair is now ready for use!

Seat Height:

• Find the flat lever on the right side under the seat pad.

• While seated, 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:

• While seated, locate the flat lever on the left side to control the seat pad depth.

• 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, allow a gap of two fingers between the seat 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.
  
  

Hand-Pump Inflatable Lumbar Support:

• Adjust the lumbar support using the attached hand pump. Pump to increase support, and press the button on the valve to release air and decrease support.

• Set the lumbar support to maintain the natural curve of your lower spine.
  
  

Backrest:

• Adjust the backrest height using the ratchet system. Lift the backrest to increase the height. To lower it, lift it to its maximum height, then lower it all the way down until it clicks. You can then raise it again to the desired height.

• The backrest has a Synchro mechanism, which allows the seat to tilt slightly when the backrest is reclined, providing consistent support. This mechanism can be locked in position or left unlocked for auto-adjustment.

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

• Adjust the recline tension using the round control on the right. Twist forward to increase tension and backward to decrease tension.
