Round Tube Office Chair

A round tube office chair is a type of office chair that uses round tubes as its main structural support components, and there are related products and supporting production links in the market.

I. Directly Related Products
The Jueyue brand has launched a folding recliner. Its structure adopts a design of all-black Oxford fabric paired with round tubes, targeting office lunch breaks and home leisure scenarios. Although this product is not explicitly labeled as an 'office chair', it has auxiliary functions in office scenarios (such as for lunch breaks), and the round tube structure highly matches the support requirements of office chairs, so it can be regarded as a sub-category of round tube office chairs. Such products usually use lightweight round tubes (such as carbon steel tubes with a diameter of 25 - 32mm), connecting the seat surface and the frame through welding or snap-fit processes, balancing portability and load-bearing capacity.

II. Enterprises Related to the Production Process

1. Material Supply Side: Wuxi Huijuyuan Metal Products Co., Ltd. wholesales Q195 small-diameter cold-drawn thin-walled round tubes and Q235 furniture round tubes. These materials are the core raw materials for office chair frames. Q195 round tubes have a wall thickness of 0.8 - 1.5mm and are suitable for non-load-bearing parts such as chair backs and armrests; Q235 round tubes have a wall thickness of 1.5 - 2.5mm and are often used for load-bearing structures such as chair legs and five-star bases. Their yield strength reaches 235MPa, which can meet the dynamic load-bearing requirements of office chairs.
2. Equipment Manufacturing Side: The round and square tube automatic punching and necking machine produced by Zhangjiagang Yousheng Machinery Manufacturing Co., Ltd. can be directly applied to the processing of round tubes for office chairs. This equipment uses CNC technology to perform processes such as necking at the ends of round tubes and punching on the side walls, with an accuracy of ±0.1mm, ensuring the assembly stability at the connection points of chair legs. It is a key piece of equipment for the large-scale production of round tube office chairs.

III. Potential Production Capacity
Although Foshan Xiangju Seat Manufacturing Co., Ltd. does not explicitly mention round tube office chairs, its main business covers public seats such as auditorium chairs and school desk chairs. These products often use round tubes or square tubes as support structures (such as the chair legs of auditorium chairs and the frames of school desk chairs), indicating that the enterprise has technical accumulation in round tube processing and seat assembly, and there is a possibility of extending its production to round tube office chairs. Its production process may include round tube cutting, tube bending and forming, welding and assembly, etc., which highly overlap with the conventional manufacturing process of office chairs.

IV. Market Positioning and Trends
Round tube office chairs are mostly positioned in the entry-level market or temporary office scenarios due to their simple structure and relatively low cost. With the increasing demand for lightweight design, some mid-to-high-end products have started to use aluminum alloy round tubes (with a density of 2.7g/cm³, only one-third of that of steel), paired with breathable mesh seat surfaces, forming a new trend of 'round tube frame + ergonomic design'. Such products optimize the ratio of the diameter to the wall thickness of the round tubes (such as a diameter of 38mm and a wall thickness of 2mm), reducing weight while ensuring strength and improving mobility.
