Replacing Office Chairs

Replacing office chairs can be divided into two scenarios: individual replacement and corporate replacement, as detailed below:

Individual Replacement of Office Chairs
If a computer office chair shows issues such as cushion sagging, surface damage, or fabric tearing due to long-term use, replacing the cushion yourself can save costs. Steps for operation are as follows:

1. Measure dimensions: Use a tape measure to determine the installation hole dimensions of the old cushion to ensure the new cushion matches the chair base.
2. Remove the old cushion: Flip the chair and place it on a stable stool. Use an Allen wrench to unscrew the bolts securing the base and armrests, and carefully remove the old cushion.
3. Install the new cushion: Place the new cushion on the stool, align the chair base with the cushion's bolt holes, and tighten the bolts one by one to secure the base.
4. Adjust the armrests: After reinstalling the armrests, adjust the tightness of the bolts to ensure the armrests are stable and meet your usage habits.
   Precautions: Before operation, confirm that the bolt specifications match the tools to avoid slipping; if the chair has a complex structure (e.g., gas lift, five-star base), refer to the product manual or consult a professional.

Corporate Replacement of Office Chairs
Taking ByteDance as an example, it launched a centralized office chair replacement plan for its domestic workplaces starting in August 2026, with the core goal of unifying the workplace experience and addressing employee feedback on comfort issues (e.g., backrests that cannot be locked). Implementation details are as follows:

1. Replacement scope: Covers major domestic workplaces such as Fangheng and Dazhongsi in Beijing, and Xinjiangwan in Shanghai, with plans to complete large-scale replacement by the second quarter of 2027.
2. Product selection: Replacing the Humanscale brand with the "Qingxian s1" model, which was selected through internal small-scale experimental voting, balancing ergonomic design and cost-effectiveness.
3. Replacement logic: Corporate replacements are usually based on chair wear and tear from long-term use, employee health needs (e.g., lumbar support), or brand strategy adjustments, requiring processes such as administrative approval, supplier negotiations, and logistics coordination, with a longer cycle and involving bulk procurement.

Summary: Individual replacement focuses on cost and operability, while corporate replacement requires overall coordination of efficiency, experience, and cost control. In either scenario, it is essential to prioritize confirming the structural compatibility of the chair to avoid installation failures due to size or design differences.
