Swedish Office Chair Casters
The materials, functions, and safety standards of Swedish office chair casters vary depending on the specific model. Common materials include polypropylene plastic paired with synthetic rubber or thermoplastic elastomer, and they generally support locking functions and comply with international safety standards.
In terms of materials, a common combination for Swedish office chair casters is polypropylene plastic paired with other elastic materials. For example, the casters of the LÅNGFJÄLL conference chair use a combination of polypropylene plastic and synthetic rubber, which balances wear resistance and quiet operation, making them suitable for hard floors. The FJÄLLBERGET conference chair with casters uses polypropylene plastic with thermoplastic elastomer; the latter offers better resilience, further reducing noise during sliding and adapting to minor undulations on different floors.
Regarding functional design, Swedish office chair casters generally feature a locking function. The casters of both the LÅNGFJÄLL and FJÄLLBERGET conference chairs support locking, allowing users to fix the chair in place when not in use by operating the locking mechanism on the casters (such as pressing or rotating structures), thereby avoiding safety hazards caused by accidental sliding. This design is particularly suitable for scenarios requiring a stable sitting posture, such as during meetings, writing, or using a computer.
In terms of safety standards, Swedish office chair casters strictly adhere to international regulations. The casters of the LÅNGFJÄLL chair meet the EN 16139-Level 1 standard, which sets requirements for the strength and durability of office furniture, ensuring that the casters do not fail structurally due to wear or pressure during long-term use. The casters of the FJÄLLBERGET chair comply with both the EN 16139-Level 1 and ANSI/BIFMA x5.1 standards; the latter is a safety specification developed by the American National Standards Institute/Business and Institutional Furniture Manufacturers Association, which imposes stricter requirements on indicators such as the load-bearing capacity and rolling resistance of casters, further enhancing the safety and reliability of the product.
Additionally, although some Swedish imported office chairs do not provide detailed descriptions of the caster materials or functions, the description of being "slidable" indicates that they have basic mobility functions. Users can choose whether to equip them with locking devices or casters of specific materials based on their actual needs.
