| Daily sitting duration | More than 6 hours per day | Adjustable seat height, backrest recline, lumbar support, and armrests | Longer work periods require more adjustment options to accommodate different postures and body sizes. | Request an adjustment checklist and test sample chairs with employees from different departments. |
| Employee height range | Approximately 155–190 cm | Seat-height range of about 42–52 cm and a seat depth of about 45–50 cm | A broad adjustment range helps more employees maintain stable foot contact and suitable thigh support. | Compare the chair adjustment range with anonymized employee height data. |
| Different body weights | Shared use by a mixed employee population | Published weight capacity of at least 120 kg; consider 150 kg for higher-demand areas | A suitable capacity supports safer shared use and reduces the risk of premature component failure. | Review the manufacturer’s documented load rating and applicable test reports. |
| Posture support | Employees who alternate between typing, reading, and meetings | Height-adjustable lumbar support, recline range of approximately 90°–120°, and tension control | Flexible support allows users to adjust the chair for upright computer work and relaxed task changes. | Have users evaluate upright support, recline stability, and control accessibility. |
| Desk and workstation compatibility | Standard desks with fixed or adjustable heights | Armrests that adjust in height and width, with a maximum height that fits beneath the desk | Compatibility prevents blocked legroom, desk collisions, and unnecessary furniture replacement. | Measure desk clearance and test armrest movement under representative workstations. |
| Office environment | Open-plan areas, private offices, and shared workspaces | Breathable mesh or durable fabric, quiet casters, and a stable five-point base | The right materials can improve airflow, reduce noise, and support frequent movement across different floor types. | Test samples on carpet, hard flooring, and common office surfaces during normal work activities. |
| Cleaning and maintenance | High-use shared seating and hot-desking areas | Stain-resistant upholstery or cleanable mesh, replaceable casters, and accessible adjustment mechanisms | Easy maintenance helps standardize cleaning procedures and lowers long-term service effort. | Obtain care instructions, replacement-part availability, and a list of approved cleaning agents. |
| Safety and durability | Daily commercial use over multiple years | Commercial-use construction, reinforced base, reliable tilt mechanism, and documented durability testing | Consistent construction reduces variations between units and supports predictable replacement planning. | Check test documentation, inspect production samples, and confirm quality-control procedures. |
| Accessibility and inclusive use | Employees with varied mobility and ergonomic requirements | Low operating force, intuitive controls, stable seat edge, and optional configurations for specific needs | Inclusive features make standard seating more practical across a diverse workforce. | Invite a representative user group to assess controls, transfers, stability, and comfort. |
| Bulk-order logistics | Large quantities delivered in phases or to multiple locations | Stackable or space-efficient packaging, clear assembly instructions, spare parts, and consistent specifications | Efficient delivery and standardized parts simplify installation, inventory control, and future replacements. | Confirm carton dimensions, assembly time, delivery schedule, spare-part policy, and inspection procedures. |
