Adjustable Office Chair Parameters
The parameters of adjustable office chairs mainly include three aspects: structural composition and core parameters, functional parameters, and other parameters.
Structural Composition and Core Parameters: The base is the fundamental supporting component of an adjustable office chair. It is usually made of cast iron and disperses pressure through a five-claw or circular design. Some products can bear loads of up to 150 kilograms, ensuring stability during use. The gas lift is the core component for height adjustment, achieving the lifting function through internal air pressure changes. It must comply with safety certification standards to ensure user safety. The common thickness of the seat cushion is about 5 centimeters, filled with sponge or memory foam inside, which can effectively disperse body pressure and enhance comfort. The backrest comes in two types: high and low. The high backrest can support from the waist to the shoulders. For some products, such as the Deli 4905, the backrest width is 44 centimeters, and the maximum backrest angle can be adjusted between 120 and 155 degrees to meet different sitting posture needs. The armrests are mostly made of engineering plastics. Some products are equipped with adjustable armrests to adapt to different sitting postures. For example, the Deli 4905 has fixed armrests with a height of 16.5 centimeters.
Functional Parameters: The lifting function is achieved through the gas lift, and the seat height adjustment range varies by product. For example, the Deli 4905 has a range of 45 to 53 centimeters. The swivel function enables 360-degree free rotation through the bottom bearing, facilitating flexible direction adjustment for users. The headrest design can slide up and down to fit the neck support needs of users of different heights. For example, the JD.COM Jingzao Z5 Pro is equipped with a 2D large-arc headrest. The backrest adjustment function, such as that of the JD.COM Jingzao Z5 Pro, provides a 50mm adjustable backrest with 3-level lumbar support modes to enhance lumbar support. The seat cushion design, such as that of the JD.COM Jingzao Z5 Pro, uses a 10.5cm thickened high-elastic pressure-relieving seat cushion to further improve comfort.
Other Parameters: The seat width and depth affect the user experience. For example, the Deli 4905 has a seat width of 50 centimeters and a seat depth of 49.5 centimeters, suitable for most body types. The overall dimensions, such as those of the Deli 4905, are approximately 6ร49.5ร91 centimeters, facilitating reasonable planning of office space. Color options, such as those of the Deli 4905, include classic black and elegant gray, meeting different aesthetic needs. The five-star foot material, such as that of the Deli 4905, uses a steel five-star foot to enhance the durability of the overall structure.
