Hengyao - Wholesale Office Chair Production Process

Office chair metal tube material preparation

2. Drilling

Connection holes are processed for screws, armrest parts, mechanism fitting, and other assembly points that affect final chair stability.

Office chair tube trimming and edge finishing

3. Tube Trimming

Edges and burrs are removed so frame parts fit more cleanly during welding, assembly, and final inspection.

4. Welding

Frame parts are welded according to the chair structure, helping keep key load-bearing areas stable before surface treatment.

5. Polishing

Welded areas are polished to remove rough points and prepare the frame for coating and later assembly.

Office chair frame cleaning before coating

6. Surface Cleaning

The frame surface is cleaned before coating so the finish is more stable and easier to inspect.

7. Powder Coating

A protective coating is applied to the metal frame surface to improve appearance and basic surface protection.

8. Finish Check

The coated frame is checked for surface finish, visible defects, color consistency, and preparation for assembly.

How to Choose Model 777 for Ergonomic Mesh Office Chair Bulk Orders

Model 777 should be evaluated as an ergonomic mesh office chair for buyers who need a stronger lumbar-support story, visible adjustment features, and reliable daily office use. Before confirming a bulk order, check 4D lumbar movement, 2D headrest fit, flip-up armrest stability, mesh tension, seat support, gas lift movement, base balance, caster rolling, carton protection, 504 pcs/40HQ loading, and sample-to-bulk consistency.

Check Whether 4D Lumbar Support Matches Your Buyer Positioning

Choose 777 when the buyer wants to market better back support instead of only a low price. The 4-direction lumbar support should move smoothly, hold position after adjustment, and feel consistent between the approved sample and bulk production. This matters for corporate offices, coworking spaces, manager rooms, and distributor catalogs where end users compare comfort quickly.

Check Headrest, Armrest, and User Adjustment Stability

Reliable choice: stable 4D lumbar, 2D headrest, and flip-up armrests

For ergonomic office chair orders, complaints often come from loose headrests, uneven armrests, weak lumbar movement, or adjustment parts that feel different from the sample. Ask for close-up function checks, sample notes, and pre-shipment videos before mass production.

Avoid pitfalls: loose lumbar parts, weak gas lift, unstable base, or poor packing

Do not judge 777 only by the product photo. Check lumbar movement, headrest fitting, armrest alignment, gas lift travel, base balance, caster rolling, screw matching, carton marks, and spare parts before shipment.

Check Mesh Tension, Seat Support, and Long-Hour Comfort

777 uses breathable mesh, 4-direction lumbar support, 2D headrest, flip-up armrests, 17 butterfly mechanism, and office-use moving parts. These features should be checked as one seating system because a chair can look ergonomic but still create complaints if mesh tension, seat support, or adjustment movement is inconsistent.

Check Bulk Order Risk: Function, Packing, and 504 pcs/40HQ Loading

For B2B pricing, confirm the 64 x 30 x 60.5 cm packing size, 504 pcs/40HQ loading, label requirements, hardware kit, spare parts, and inspection records before final quotation. Compare 999 for a stronger premium mesh story, 779 for 3D armrest positioning, 777-2 for lower-cost mesh programs, and the office chair category for broader model comparison.

How to maintain your office chair

Follow this care guide to keep the 777 ergonomic mesh office chair clean, stable, and suitable for daily office, workstation, manager room, and coworking space 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.

The product is very good and i truly like it. However, items that require assembling should always come with a manual included in the box. It makes it easier for customers to put everything together. Otherwise, the set is really beautiful.

Isabella Jackson

Australia

After the purchase, the seller did not reply to my messages even though they had read them, and did not assist me with the necessary documents to receive the goods. I could not complete the procedures to receive the goods because the seller did not provide them; they simply washed their hands of responsibility after the sale.
