Customization of Elderly Care Office Chairs

The customization of elderly care office chairs requires a comprehensive consideration of the physical characteristics of elderly users, functional requirements in office settings, and compliance with institutional procurement standards. The design focuses on three key dimensions: preventing falls, facilitating easy standing, and minimizing pressure, while strictly controlling material selection and the customization and adaptation process.

I. Core Points of Elderly-Friendly Design

1. Fall Prevention and Stability: Edges and corners should be rounded to avoid bumps; armrests should be designed as continuous grippable structures to assist the elderly in standing up; chair legs should have anti-slip functions and a reasonable center of gravity distribution to reduce the risk of tipping over.
2. Easy Standing and Ergonomics: The seat height should be slightly higher than that of ordinary office chairs (usually 45-50cm) to facilitate leg exertion by the elderly; the seat depth should be appropriately narrowed (about 40-45cm) to prevent excessive forward extension of the legs during prolonged sitting; the backrest should provide lumbosacral support to distribute spinal pressure.
3. Minimizing Pressure and Comfort: The prolonged sitting area should use zoned support foam with different hardness combinations (e.g., softer front and harder back of the seat cushion) to avoid prolonged pressure on the coccyx and ischial tuberosities; the seat inclination angle is recommended to be 3-5° to promote blood circulation.

II. Material Selection and Safety Standards

1. Panel Materials: Must comply with E0 or ENF environmental protection standards (formaldehyde emission ≤ 0.025mg/m³) and provide batch-specific test reports; preference should be given to flame-retardant solid wood particle boards that balance environmental protection and fire resistance.
2. Foam: Adopt a combination of “high density (≥45kg/m³) + zoned hardness” to ensure a balance between support and comfort; must pass the GB 8624-2012 flame-retardant test and achieve a quasi-safety level 1 (ZA1) for smoke toxicity indicators.
3. Hardware and Structure: Connectors must pass salt spray tests (≥500 hours), compression (≥500kg) and tensile (≥300kg) tests; steel frame structures are recommended to use rubberwood solid wood frames or thickened steel pipes (wall thickness ≥ 2mm) to enhance load-bearing capacity.

III. Customization Adaptation and Process Specifications

1. Space Measurement and Modular Design: For irregular spaces or non-standard dimensions, suppliers should provide free on-site measurements and offer floor plans and cabinet decomposition diagrams; adopt modular structures (e.g., detachable armrests, adjustable chair legs) to facilitate on-site adjustments and future modifications.
2. Error Control and Inspection Process: Panel cutting errors should be controlled within ±1mm; follow an “inspect before assembly” process, where manufacturers like Sichuan Xinruida conduct secondary inspections of panels and foam before assembly to ensure compliance.

IV. Price Reference and Procurement Recommendations

Customization prices vary significantly depending on brand, material, and functionality: Fixed chairs for nursing homes in Zhengzhou, Henan, cost about 1190 yuan per set; elderly-friendly dining chairs in Chengdu, Sichuan, cost about 240 yuan each; elderly-friendly furniture in Dezhou, Shandong, costs about 298 yuan per piece; elderly-friendly dining chairs in Guangzhou, Guangdong, cost about 540 yuan each. It is recommended to prioritize manufacturers that provide “test reports + after-sales maintenance” and clearly define environmental protection and safety liability clauses in contracts.
