[0002] Bamboo board chairs are made from natural bamboo through specific processing steps. Bamboo is a natural material that grows quickly and has strong regenerative capabilities. Using bamboo boards to make chairs aligns with modern people's pursuit of environmental protection and sustainable development. After processing, it presents a natural and rustic aesthetic, suitable for various home decor styles. Its high plasticity allows it to be made into various shapes. With proper processing, the resulting chairs are structurally sturdy, capable of bearing a certain weight, and have a long service life. Bamboo board chairs that have undergone carbonization treatment have insect- and mildew-resistant properties, making them less susceptible to insect infestation and mold, further extending their lifespan. Despite the diversification of modern furniture, bamboo board chairs remain popular due to their environmental friendliness, durability, and price advantage.

[0003] A search revealed Chinese Patent Publication No. CN220001296U, which discloses a chair comprising a seat cushion, legs, and a backrest. Multiple legs are connected to the lower surface of the seat cushion. The seat cushion has a first threaded hole, and the backrest has a second threaded hole. Threaded fasteners can be sequentially screwed into the first and second threaded holes. When the threaded fasteners are tightened, the ends of the fasteners are completely within the second threaded hole. The chair provided by this utility model allows for a detachable connection between the backrest and seat cushion using threaded fasteners, enabling disassembly during transport and reducing packaging and transportation costs. Furthermore, when the threaded fasteners connecting the backrest and seat cushion are tightened, the ends of the fasteners are completely within the second threaded hole, making the connection more aesthetically pleasing and reducing safety hazards. However, in resting situations, a chair with a fixed angle significantly reduces comfort. Additionally, its fixed backrest angle fails to conform to the natural curve of the human spine, preventing the shoulders and neck from relaxing naturally, and limiting its usability in various scenarios. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bamboo board chair, which aims to improve the existing technology where the inability to adjust the angle of the chair in a resting setting greatly reduces comfort. At the same time, the fixed backrest angle cannot conform to the natural curve of the human spine, the shoulders and neck cannot relax naturally, and the chair is restricted in different usage scenarios.
