Office Chair Armrest Tutorial

Admin October 16, 2026

The installation tutorial for office chair armrests is mainly divided into two cases: for specific models of chairs and for other types of chairs. Here are the details:

Installation Tutorial for Armrests of Chair NB219

  • Distinguish between left and right armrests: Before starting the installation, carefully identify the left and right armrests. Since left and right armrests have specific requirements in terms of design and installation position, incorrect orientation will prevent proper installation and may even damage chair components. So be sure to distinguish them carefully to avoid confusion.
  • Align with the holes: Place the identified left and right armrests accurately over the corresponding holes on both sides of the seat cushion. This step requires patience and care to ensure that the armrests fit perfectly with the holes, preparing for the subsequent fixing work. If the holes are not aligned, forced installation may result in the inability to screw in the screws or an insecure installation.
  • Screw in the screws for fixation: Use 2.5-centimeter hexagon socket screws to fix the left and right armrests to the seat cushion respectively. When screwing in the screws, pay attention to applying an appropriate and even force to ensure that the armrests are firmly installed and will not wobble or loosen during use. You can use a suitable hexagon socket wrench and gradually tighten the screws in a clockwise direction.

Installation Tutorial for Armrests of Other Types of Office Chairs

  • Prepare tools and components: Before installation, prepare the armrests and the required screws. Ensure that the quantity and specifications of the screws match the requirements of the chair to avoid affecting the installation progress and quality due to missing or incorrectly sized screws.
  • Align with the holes: Accurately align the armrests with the holes on both sides of the seat cushion. This step is similar to the installation of chair NB219, and it is necessary to ensure a perfect match between the armrests and the holes to lay the foundation for subsequent fixation.
  • Fix with screws: For example, use three screws to fix the left armrest. Screw in the screws in a certain order (such as from the middle to both sides) to ensure a stable installation of the armrest. The installation method for the right armrest is the same as that for the left one, using the corresponding number of screws for fixation. When screwing in the screws, pay attention to applying an even force to avoid the screws being screwed in crookedly or an uneven installation of the armrests.
