How to Disassemble the Gas Lift from an Ergonomic Chair?

As a mesh chair manufacturer specializing in the production of executive chairs and staff chairs, Shunmas Ergonomic Chair Factory combines 15 years of production experience to explain the gas pressure rod disassembly process for you. Master the following steps to easily cope with office chair maintenance needs:

Tools Preparation
• Rubber Hammer: To protect the surface and ensure precise tapping.
• Screwdriver Set: For different screw types.
• Lubricating Grease (Recommended): Essential for maintaining metal parts.

Disassembly Process

Safety First
       Turn the ergonomic chair upside down, with the base facing up. The five-star base design of staff/office chairs provides more stability, but be careful to avoid sharp objects on the floor.

Base Separation Technique
• Inspect the plastic protective sleeve at the base of the gas lift. Use a flathead screwdriver to pry around the edge.
• For the metal clip connection, insert the prying tool at a 45-degree angle.
• When tapping, apply force evenly in a circular motion to prevent deformation of the integrated base, which is common in office chairs.

Seat System Disassembly
Modern mesh chairs often use quick-release designs:

1.Remove the screws that attach the armrests (some executive chairs with synchronous tilt mechanisms may need to be unlocked first).

2.Lift the anti-explosion steel plate (a safety feature) and disconnect the gas lift from the seat’s locking mechanism.

3.For stubborn connections, apply lubricating grease and let it sit for 2 minutes.

Professional Tips
√ Use a magnetic screwdriver to prevent parts from falling.
√ Be cautious of the wiring clips when removing the mesh backrest to avoid pulling and damaging it.
√ After removing the gas lift, store it vertically to prevent hydraulic fluid leakage.

Safety Warnings
! Do not strike the black nitrogen piston rod (visible silver warning ring).
! If the gas lift is leaking or rusted, replace it immediately (SGS-certified parts have a lifespan of about 5 years).
! For complex structures, it's recommended to contact the original factory for after-sales support (keep the backrest label serial number).

This guide is suitable for 95% of office chair structures. For specific models, please refer to the product manual. Regular maintenance not only extends the lifespan of office and staff chairs but also helps protect the user's spinal health.
