Office Chair Installation Tutorial

Admin October 10, 2026

Here is the office chair installation tutorial:

Basic Installation Steps

  • Caster and Five-Star Base Installation: Insert each caster into the mounting holes of the five-star base one by one. Ensure that each caster is firmly installed to prevent looseness.
  • Gas Lift Installation: Turn over the five-star base and place the thicker end of the gas lift into the center hole of the five-star base. Make sure the gas lift is vertical and stable.
  • Seat Base and Cushion Connection: Place the seat base on the cushion, paying attention to its orientation. Align it with the four screw holes, then gently screw in the four screws 3 - 4 turns one by one, and then tighten them gradually to ensure a tight connection between the seat base and the cushion.
  • Cushion and Gas Lift Connection: Align the cushion with the gas lift and insert it into the hole in the seat base. Ensure that the cushion is placed steadily on the gas lift.

Backrest Installation

  • Backrest and Armrest Connection: Align the two sides at the bottom of the backrest with the installation positions of the armrests on both sides of the cushion and insert them. First, use two screws to fix the bottom of the backrest from the bottom of the armrest brackets to ensure the initial fixation of the backrest.
  • Backrest and Seat Base Bracket Fixation: Align the installation holes at the back of the backrest with those on the seat base bracket. Then, use two wrenches to lock and fix the backrest and the seat base bracket with screws to ensure that the backrest is stable and does not wobble. Some installation methods also involve screwing the backrest and the seat onto angle brackets or inserting the backrest into the tray and then inserting the assembled chair onto the gas lift. You can choose the appropriate method according to the specific chair structure.

Armrest Installation

  • Armrest Insertion: Press the button below the armrest surface and insert the left and right armrests into the holes of the armrest brackets respectively. Ensure that the armrests are inserted in place.
  • Armrest Fixation: Take the screws needed for the armrests and use No. 3 screws to fix the armrests on the brackets. Fix the right armrest with three screws in the same way as the left one to ensure that the armrests are firmly installed.

Headrest Installation

  • Headrest Placement: Place the headrest in the middle at the top of the backrest. Press the installation part of the headrest to make it fit the backrest better and ensure that the headrest is in the right position.
  • Headrest Fixation: Use two screws to pass through the headrest fixing buckles to fix the headrest. First, gently screw in the screws 3 - 4 turns and then tighten them one by one to prevent the headrest from loosening.

Other Steps

  • Some tutorials mention installing the five casters first, then inserting the gas lift, followed by placing the seat base under the cushion and installing four long screws on the base, which is similar to the basic installation steps. There are also tutorials that mention gently tapping the cover in with a small tool, which may be for the installation of certain components with covers.
