Hengyao – Wholesale Office Chair Production Process
1. Cutting Tube
We use high-quality metal pipes as the main raw material to ensure that the basic structure of each commercial office chair is sturdy, stable, and suitable for repeated B2B use.
2. Drilling Hole
Using high-precision CNC cutting equipment, the pipe materials are precisely cut according to the design drawings, ensuring that the size error of each section is kept within an extremely small range.
3. Blending Tube
Carry out secondary precision cutting and edge trimming on the pipe materials, removing burrs and excess edges and corners, to make the surface of the components smooth and flat.
4. Hand Welding
According to the structural design of the chair, precise holes are drilled at the designated positions of the pipe, facilitating the subsequent screw fixation and component assembly.
5. Polishing
The components are fully welded to ensure that each solder joint is firm and without any voids, thereby enhancing the overall strength of the frame.
6. Cleaning Impurity
Carry out a thorough polishing of the welded frame to remove the weld marks and rough surfaces.
7. Powder Coated
Using the environmentally friendly electrostatic powder spraying technology, a uniform protective coating is formed on the surface of the metal frame.
8. Wooden Grain
After powder coating, the frame undergoes high-temperature curing treatment, and the coating firmly adheres, resulting in a finished frame that is both aesthetically pleasing and protective.
9. Quality Checking
The qualified frame is professionally assembled with the seat, backrest and other accessories to complete the office chair assembly.
10. Frame Assembly
Use multi-layer protective packaging materials to provide cushioning and wrapping for the finished office chairs.
11. Loading Container
The completed office chairs will be neatly stored and ready to be dispatched to customers all over the world at any time.
Fully Customized Manufacturer
Sourcing – sampling – production – quality inspection – export packing – delivery support for B2B office chair programs.
How to Choose 998-B for High-Back Mesh Office Chair Projects
998-B should be evaluated as a high-back mesh office chair for project and distributor use, not as a simple low-price task chair. Before confirming a bulk order, buyers should check whether the high-back size, 3D headrest range, and height adjustable lumbar support match the target user group.
The sample check should include mesh rebound, seat new foam support, 3D flip-up armrest movement, base balance, caster rolling, carton protection, and sample-to-bulk consistency. These details matter because a premium-looking chair can still create complaints if support points, packing, or assembly details are not confirmed early.
Check High-Back Profile, Headrest Fit, and Lumbar Height
The high back is the main reason to choose 998-B. During sample review, ask users of different heights to test whether the 3D headrest can be positioned behind the neck without forcing the head forward. Then adjust the lumbar support through its available range and check whether it reaches the lower-back area without creating a hard pressure point.
Record the approved headrest and lumbar positions with sample photos or a short function video. This gives project buyers a clearer reference when checking whether bulk production matches the approved sample.
Check Mesh Tension, Seat Foam, and Daily Office Comfort
Reliable choice: mesh support, headrest fit, and seat comfort
For office projects, comfort problems often come from weak mesh tension, poor seat support, or inconsistent bulk production. Compare the approved sample with pre-shipment photos and function-check videos before confirming loading.
Avoid pitfalls: weak mesh, loose headrest, unstable base, or poor carton protection
For distributor and project orders, ask for close-up checks of mesh tension, headrest adjustment, screw matching, gas lift movement, mechanism function, base balance, caster rolling, spare parts, labels, and carton marks.
Check Gas Lift, Mechanism, Base, and Castors
Test the height adjustment through repeated up-and-down movement, then check that the mechanism operates smoothly without unusual play or noise. Inspect the connection points between the seat, mechanism, gas lift, and base before the chair is packed. The base should sit level on a flat surface, and the castors should roll without dragging or wobbling.
Ask for a short function video and pre-shipment inspection photos showing the under-seat mechanism, gas lift, base, and castors. A high-back chair may look premium in photos, but unstable moving parts can create the most expensive after-sales problems.
Check 352 pcs/40HQ Loading and Project Cost Control
998-B uses a 59 x 37 x 71 cm packing size with a 352 pcs/40HQ loading reference. Before approving the quotation, confirm the carton construction, hardware-kit layout, assembly manual, carton marks, spare-parts plan, and whether mixed-model loading is needed.
The buyer should also confirm the loading plan and shipment documents in writing before production starts. This makes it easier to compare freight, landed cost, warehouse handling, and project delivery timing without relying only on a headline unit price.

How to maintain your office chair
Follow this care guide to keep the 998 height adjustable mesh office chair clean, stable, and ready for staff office, manager room, and shared workspace use.
Regular Cleaning
Clean the mesh or fabric surface with a soft cloth or suitable fabric cleaner, and avoid harsh chemical cleaners. For commercial office use, regularly check the gas lift, screws, armrests, castors, and base connection to keep the office chair stable during daily operation.
Regularly inspect the connecting screws
Over time, the screws might loosen. So, let’s check if they are loose.
Avoid Direct Sunlight
Prolonged direct sunlight may fade mesh or fabric surfaces. For showrooms or project sites, keep chairs away from long direct sunlight where possible.
Proper use of the office chair
Use the chair for normal seated office work only. Do not stand on the chair, sit on the armrests, jump on the seat, overload the mechanism, or use the chair as a ladder.
Maintenance of the lifting/rotating function
Every month, apply a small amount of silicone-based lubricant (do not use engine oil) at the rotating shaft and the pedal ring to ensure smooth operation.
Avoid frequent violent lifting and lowering, and single-point heavy pressure to prevent damage to the air pressure rods.
Metal (ironwork / stainless steel / electroplated)
Dry off the water stains. In damp environments, apply a thin layer of anti-rust oil / sewing oil regularly.
Remove rust: For small rust spots, soak them in oil and then wipe them off. For severe rust, seek professional treatment.
