Simple Office Chair Specifications

The specifications of simple office chairs cover structural materials, dimensions, functions, and other parameters, as detailed below:

Structural Design and Materials
The main frame of a simple office chair is primarily made of metal or engineering plastics. Metal frames (such as steel) offer high strength and stable load-bearing capacity, while engineering plastics are lightweight and corrosion-resistant. The covering materials for the seat and backrest are divided into two categories: leather and breathable fabric. Leather has a smooth surface that is easy to clean, suitable for environments that pursue a sense of quality. Breathable fabric, through its mesh structure, enhances air circulation and reduces the feeling of stuffiness during prolonged sitting. The internal filling uses high-density refined foam, which balances softness and resilience through a layered design—the upper layer of foam is softer, providing initial comfort, while the lower layer of high-density foam (density ≥ 45kg/m³) offers strong support and is less likely to collapse over long-term use.

Dimensions and Volume
The seat width of conventional models is approximately 50cm, with a depth of 45cm, and a height range of 90-105cm (some models support pneumatic height adjustment), accommodating users of different heights. The seat width of fixed models is usually between 40-45cm. For flexible adaptation to workstations, it is recommended to choose models with a seat adjustment range of 38-48cm to meet the needs of different body types. The volume indicated for packaging or transportation is 1m³, but in actual use, due to its compact structural design, it does not appear bulky.

Functional Features
The core functions focus on basic support, without rotating or folding designs, making them suitable for fixed workstations or meeting scenarios. Ergonomic design is reflected in three aspects:

1. Slightly curved backrest: It fits the curve of the lower back, disperses spinal pressure, and reduces fatigue from prolonged sitting;
2. Downward-sloping front edge of the seat: It reduces pressure on the thighs and promotes blood circulation;
3. Enhanced stability: The bow-shaped support has a large contact area with the ground and a low center of gravity, making it less likely to tip over.
   In terms of maintenance, the leather surface can be wiped clean with a damp cloth, and the foam filling has strong anti-deformation capabilities, maintaining its resilience after long-term use.

Other Parameters
The density of the filling directly affects the service life: high-density foam (≥ 45kg/m³) has a slow rebound but provides long-lasting support, while low-density foam is prone to collapse. It is recommended to prioritize high-density models. The quality of hardware accessories, such as screws and pneumatic rods, is tested for salt spray resistance to prevent rust and extend the overall lifespan of the chair. The color and style are mainly black leather paired with simple lines, suitable for modern office decoration styles; some models are equipped with armrests to support the arms and reduce shoulder and neck fatigue.
