Adjustable Office Chair Accessories
Common accessories for adjustable office chairs include five-star bases, trays, chassis, gas cylinders, chair feet, and explosion-proof lifting rods, among others. Here is a detailed introduction:
The five-star base is the core supporting component of an adjustable office chair, typically divided into two types: detachable and integrated. The detachable five-star base adopts a detachable design, facilitating transportation and installation, with a price of approximately ยฅ55.0. The aluminum alloy five-star base offers higher strength and corrosion resistance, suitable for long-term use scenarios. Some high-end products use thickened steel or engineering plastics to enhance load-bearing capacity and stability.
The tray, as the hub connecting the seat surface and the gas cylinder, directly affects the adjustment function of the chair. The die-cast aluminum alloy tray is formed through precision casting, featuring high structural strength and light weight, with a price of approximately ยฅ38.0. Its surface is usually anodized to effectively prevent oxidation and corrosion. The multifunctional chassis integrates complex mechanisms such as tilt locking and height adjustment, with a relatively high price (approximately ยฅ92.0), but it provides a richer user experience, such as backrest angle locking and seat depth adjustment.
The gas cylinder is the key component for realizing the lifting function of the chair. It is classified into four levels according to pressure rating. The price of a third- or fourth-level gas cylinder spring is approximately ยฅ14.6. It is filled with high-pressure nitrogen gas internally and achieves smooth lifting through piston movement. High-quality gas cylinders need to pass BIFMA certification to ensure no explosion risk under frequent use. The explosion-proof lifting rod provides double protection in case of gas cylinder failure through special structural design, further enhancing use safety.
The material and structure of the chair feet directly affect the mobility of the chair. An aluminum alloy five-star base paired with silent wheels is suitable for hard floors; a cross-shaped or four-star chair foot design saves more space and is suitable for small office environments. Some products use nylon-reinforced materials to reduce weight while ensuring strength. The hydraulic gas spring achieves lifting through hydraulic principles, featuring good cushioning effect and low noise, but relatively high cost.
Purchase recommendations: Prioritize accessories that have passed international safety certifications (such as BIFMA and SGS), focusing on the explosion-proof performance of the gas cylinder and the adjustment function of the chassis. Choose appropriate materials according to the use scenario. For example, in humid environments, it is recommended to use aluminum alloy or stainless steel accessories to extend service life.
