Step 3: Attach the seat plate to the underside of the seat cushion

Identify the front of the seat cushion, then place the seat plate so the screw holes align perfectly. Professional how to assemble an ergonomic chair requires tightening screws in an X-pattern to distribute pressure evenly and avoid warping the plastic frame. Use the included hex key to securely fasten each point, but avoid overtightening to prevent damaging the screw threads.

Step 4: Attach the seat cushion onto the chair cylinder

Lift the seat cushion with the attached seat plate and slowly place the center hole onto the hydraulic piston head already positioned on the base. The most effective way to assemble an ergonomic chair is to gently press down on the seat cushion with your hand to help the joint grip firmly and stabilize the center of gravity. Test sit to check if the system shakes or makes strange noises after completing this assembly step.

Step 5: Attach the backrest

Insert the backrest frame into the slot behind the seat plate, then use long screws to secure it in place. The curved frame system needs to be adjusted to closely follow the spine's natural curve, helping relieve daily lumbar pressure. Gently shake the backrest after tightening the screws to ensure this part remains sturdy and does not shift during work.

 

 

Step 6: Attach the armrests

Identify the left and right armrests according to the manufacturer's markings, then fit the joints correctly into the sides of the plastic seat plate. How to assemble an ergonomic chair requires you to keep both armrests at a balanced height to support the arms in a proper position. Tighten the screw points under the seat to ensure the armrest supports do not wobble during data processing.

Step 7: Attach the headrest

Insert the headrest joint into the top slot of the backrest frame, then use short screws to securely fasten this neck support component. This part needs to have its height adjusted to fully match the cervical spine, promoting good blood circulation and reducing daily neck and shoulder fatigue. Gently rotate the component to check the flexibility of the swivel joint, maximizing comfort when you relax.
