The core support system of a high-back laboratory chair consists of a frame, filling material, and adjustment mechanism. Taking a PP (polypropylene) frame as an example, this thermoplastic resin material boasts high strength and impact resistance. Molded using a one-piece injection molding process, it ensures both structural stability and lightweight design.
Modern office chairs focus on dynamic support needs. The swivel function is achieved through a five-claw base and 360° casters, allowing users to move freely within the office area. The headrest features an adjustable height structure to accommodate the neck support needs of users of different heights. The lumbar support provides continuous support to the lumbar spine through elastic straps or independent adjustment modules. During assembly, attention should be paid to the tightness of the connections between components to prevent loosening after prolonged use. When using the chair, keep both feet flat on the ground, thighs parallel to the ground, and back naturally against the backrest, avoiding incorrect postures such as leaning forward or backward.
