Assembly Guide
Follow these steps to assemble your FelixKing office chair. All necessary tools are included in the package.
Step 1: Attach Casters to Foot Stool
Insert the 5 caster wheels into the legs of the foot stool (chair base). Ensure each caster is firmly inserted into the innermost part of the leg to prevent it from falling out during use.

Step 4: Attach Base Plate to Seat Cushion
Fix the base plate to the bottom of the seat cushion using the M6x18mm screws and Hexagon Wrench. Ensure the "FRONT" letter printed on the base plate faces the front of the seat cushion. Tighten firmly.

Step 5: Connect Seat Assembly to Air Rod
Carefully place the assembled seat cushion (with base plate) onto the air rod, aligning the hole in the base plate with the top of the air rod. Press down firmly with your body weight to ensure a secure connection. If the air rod doesn't insert firmly, it's likely to fall down when the chair raises up.
