Office Chair Reclining Installation

The installation methods for the reclining function of office chairs vary depending on the model, and corresponding steps should be selected based on the specific model. Here are the installation methods for common reclining office chairs:

M69 Reclining Model

1. Prepare all the necessary parts and tools for installation.
2. Insert the five casters vertically into the chair base, and then insert the gas lift into the center hole of the chair base.
3. Connect the armrests to the backrest using four M8*35 screws, ensuring the screw specifications match.
4. Install the tray: Place four M635 screws with washers and use four M618 screws to secure the tray.
5. Install the armrest decorative covers, and finally connect the armrests to the seat cushion using four M6*35 screws.

NB15 Reclining Model

1. Place the backrest with its back facing up and position the side holes forward; align the armrests with the side holes of the backrest and secure them with 2.5CM hex screws.
2. Place the seat cushion with its holes facing up and position the side holes backward; align the reclining support iron plate with the center hole of the seat cushion, paying attention to the handle orientation, and secure it with 2CM hex screws.
3. Press the wheels into the holes around the five-star base, insert the large end of the gas lift into the center hole of the five-star base, and then align the round hole of the seat cushion reclining support with the gas lift and insert it.
4. Align the headrest support frame with the slot and snap it on, align the holes with the upper holes at the back of the backrest, and secure it with 2.5CM hex screws.

Universal Reclining Computer Chair

1. Inventory the parts: This includes the backrest, seat surface, chassis, five-star base, gas lift, casters, headrest (for some models), screws, and hex wrenches.
2. Assemble the base: Align the casters with the interfaces of the five-star base and press them in until you hear a 'click' to confirm they are installed properly.
3. Install the gas lift: Insert the gas lift into the center hole of the five-star base, and align the center hole of the chassis with the other end of the gas lift and press it to secure it.
4. Connect the backrest and seat surface: Align the connection holes of the two, and tighten them one by one with screws and wrenches, avoiding over-tightening at once.
5. Secure the components: Align the backrest-seat surface assembly with the holes on the chassis and secure it with fastening screws and tighten them.
6. Test the functions: Pull the reclining lock adjustment lever to test the recline angle, and confirm that the headrest adjustment is normal and there is no looseness or abnormal noise.

Computer Chair Reclining Device (Add-on or Universal)

1. Prepare the tools: Confirm that all parts are complete, lay the chair down on a soft surface, and disconnect the connection of the lifting gas lift.
2. Locate the holes: Find the 2-4 symmetrical screw holes reserved on the chassis (for add-ons, drill holes according to the template, avoiding the structure of the lifting rod).
3. Secure the main body: Align the reclining plate with the holes and tighten the screws alternately to avoid over-tightening a single screw.
4. Connect the control structure: Connect the adjustment lever to the underside or side of the armrest, leaving some slack; the spring resistance device should be hooked onto the buckles of the chassis and the reclining plate, and adjust the tightness to change the damping feel.
5. Test the functions: Stand the chair upright and shake it to test. Check if the locking/unlocking is normal; if there is stuttering, adjust the screws. If the lever does not respond, check the cable or hook.
