Shenzhen Office Chair Adjustment

The adjustment of office chairs in Shenzhen should ensure that users can easily control and complete the adjustments, and maintain stability after adjustment. The specific methods are as follows:

Adjustment Function Verification

• Control Position: Have individuals of different heights and usage habits locate the control positions without assistance from demonstrations, and then have staff explain once more, recording which functions are prone to misunderstandings. The criteria for judgment are whether they can be found, adjusted, and maintained. For example, some users may not be able to find the adjustment buttons due to unfamiliarity with the operation, or may not be able to fix the position after adjustment.
• Operation Path: Simulate common actions such as typing, reading, answering phone calls, turning around to retrieve items, and briefly leaning back, recording whether the feet are stable, whether the lower back receives proper support, whether the armrests bump into the tabletop, and whether the movement of the chair affects neighboring seats. For shared workstations, a 'quick reset' test should be added to ensure that the chair can quickly return to its initial state after multiple users.
• Adjustment Range: The seat height, armrests, and recline of the chair should be checked against the actual desktop, keyboard tray, drawers, and under-table structure to avoid interface issues such as armrests getting stuck on the table or the seat rising to a height where the knees hit the crossbeam. For example, if the seat rises to a height where the knees hit the crossbeam, it will affect comfort.
• Exception Handling: Check for loose parts, abnormal noises, inconsistent return positions, and left-right deviations. When an exception is found, record the specific action, chair number, and conditions for reproduction to facilitate timely repair or replacement.

Backrest Recline Adjustment

• Sit on the office chair, locate the adjustment handle, pull the handle, lean back slightly with your back, release the handle to fix the angle; to return to the original position, continue to pull the handle and apply a slight force with your back, and the backrest will spring back.
• The backrest flattening function is generally located on the lever below the right armrest; the forward and backward rocking function can be adjusted by rotating the black cylinder in front of the chair's gas lift to adjust the rocking amplitude.

Adjustment Recommendations

• When adjusting the seat height, ensure that your feet are naturally flat on the ground and your thighs are roughly parallel to the ground, which helps stabilize your center of gravity, keep your back naturally straight, your shoulders relaxed and spread out, and your line of sight roughly level with the top edge of the screen, avoiding excessive forward extension of the neck. At the same time, ensure that your arms hang naturally, your elbows are approximately at a right angle, and the keyboard is not too high or too low, keeping your neck, shoulders, and lower back in a relaxed state.
• When purchasing in bulk, record the adjustment range, operation path, return state, and exception handling separately, and then decide whether they are suitable for specific positions. The applicable scenarios include long-term sitting positions such as ordinary workstations, shared workstations, and conference duty stations. Configurations related to postoperative rehabilitation, special ergonomic needs, or medical advice should be provided with individual opinions by corresponding professionals.
