Office Chair with Linked Armrests
Office chair models with linked armrests include Sihoo B100Pro, Sihoo B300Pro, and UE Flow550. These products achieve coordinated movement between the armrests and the seat or backrest through different technical solutions. Below is a detailed analysis of their specific functions:
Sihoo B100Pro features a 4D linked armrest design, supporting multi-dimensional adjustment functions. Its core advantage lies in the armrests' ability to synchronously adjust their angle with the backrest as it reclines, while also offering height adjustment, forward and backward sliding, and left and right shifting capabilities. This design enables the armrests to adapt to various sitting postures. For example, when a user reclines for rest, the armrests naturally tilt to provide elbow support, preventing fatigue caused by arm suspension. The 4D adjustment mechanism is realized through a mechanical linkage structure, ensuring smooth and stable adjustments in all directions, making it suitable for office scenarios that require frequent posture changes.
Sihoo B300Pro is upgraded to a 6D circular linked armrest, adding a rotational adjustment dimension on top of the 4D features. Its armrests can perform 360ยฐ circular movements, allowing for complex angle adjustments in coordination with the backrest's recline angle. For instance, when the backrest tilts to 135ยฐ, the armrests can simultaneously rotate backward and lower in height, forming an ergonomic support surface. The 6D design is achieved through a multi-axis linkage mechanism, with high-precision bearings connecting all adjustable components, ensuring no jamming during long-term use, making it suitable for design or programming tasks that demand high support precision.
UE Flow550 achieves coordinated adjustment of seat height, seat depth, and armrests through a paddle control system. Its armrests employ a combination of gas springs and mechanical slides. When a user adjusts the seat height via the side paddle, the armrests synchronously rise or lower; when adjusting the seat depth, the armrests slide forward or backward to maintain relative position with the elbows. This integrated design reduces the need for independent adjustments, allowing users to achieve a comfortable sitting posture without operating multiple components separately. The paddle control features linear resistance design, ensuring uniform operating force and preventing adjustmentๅคฑๆง due to accidental touches.
The linkage mechanisms of the above products are realized through mechanical structures or pneumatic components, with core components made of metal to ensure durability. Some models feature high-elasticity foam covering on the armrest surface, combined with breathable mesh or PU leather, enhancing comfort during prolonged use. When selecting a product, consider the adjustment dimensions based on usage scenarios: 4D is suitable for basic office needs, 6D for multitasking scenarios, and paddle linkage for users seeking operational convenience.
