Condition of Office Chairs

The determination of the condition of office chairs requires a comprehensive assessment of their physical state, functional performance, and service life coefficient. The specific grading standards and determination methods are as follows:

I. Appearance Condition Grading

1. Brand New: No visible flaws, no scratches, stains, or deformations on the surface; hardware components (such as screws and wheels) are not loose; packaging and accessories are complete.
2. Relatively New: Slight signs of use, such as minor scratches or dust in localized areas, but does not affect the overall appearance; hardware components are not loose, and the structure is stable.
3. Moderate: Noticeable localized wear, such as paint peeling, fabric pilling, or leather cracking; metal parts may show oxidation, but functionality remains normal.
4. Relatively Old: Extensive wear or damage, such as fabric tearing, severe leather cracking, or metal rusting; the structure is loose and requires repair (e.g., wheel jamming, backrest tilting).
5. Scrap: Loss of functionality (e.g., gas lift failure, frame breakage) or presence of safety hazards (e.g., risk of gas lift explosion, wheel detachment).

II. Functional Integrity Grading

1. Brand New: 100% functional integrity; all components (height adjustment, rotation, tilt, wheels) operate smoothly.
2. Relatively New: Functional integrity ≥85%; only minor wear on individual components (e.g., slightly reduced wheel flexibility).
3. Moderate: Functional integrity between 70% and 85%; core functions (e.g., height adjustment, backrest adjustment) are normal, but auxiliary functions (e.g., wheel resistance) may be limited.
4. Relatively Old: Functional integrity between 50% and 70%; partial failure of core functions (e.g., height adjustment jamming, inability to fix the backrest).
5. Scrap: Functional integrity ≤50%; major functions cannot be used (e.g., complete failure of the gas lift, frame breakage).

III. Service Life Coefficient Grading

1. Brand New: Service life ≤0.1 year (e.g., unused or only displayed for a short period).
2. Relatively New: Service life between 0.1 and 0.3 years (lightly used with no significant wear).
3. Moderate: Service life between 0.3 and 0.6 years (moderately used with noticeable localized wear).
4. Relatively Old: Service life between 0.6 and 0.9 years (long-term use with a loose structure requiring repair).
5. Scrap: Service life ≥1.0 year (over-serviced, with substandard functionality or safety).

IV. Practical Application Recommendations

• Secondary Circulation Standards: Chairs with smooth height adjustment, flexible wheels, and intact backrests can be classified as 'Relatively New' or 'Moderate'; if the frame is cracked or the gas lift poses a hazard (e.g., air leakage, abnormal noise), they should be scrapped directly.
• Brand Premium: Chairs from brands like Herman Miller and Haworth, when in good condition, have significantly higher secondary circulation prices than scrap recycling prices (possibly 3-5 times higher).
• Depreciation Life Reference: The conventional depreciation life is 8-12 years, but school desks and chairs, due to their high frequency of use, typically have a shorter effective life than corporate office furniture by 20%-30%.

Note: Actual determination should be based on specific scenarios. For example, chairs in high-frequency use environments (e.g., internet cafes, call centers) wear out faster and may need to be scrapped earlier.
