The Office Chair Structural Strength Testing Machine is designed to evaluate the fatigue strength and durability of office chair backrests, seats, and armrests. By applying repeated loads over a set number of cycles, the machine checks the structural integrity and identifies potential failures or excessive deformations in chair components. It is an essential testing instrument for office furniture manufacturers, quality inspection agencies, and certification bodies. Functions & Applications * Simulates repeated backward loading on office chair backrests and seats. * Evaluates fatigue resistance of chair backrests, seats, and armrests. * Detects structural damage or excessive deformation under cyclic loads. * Widely used in office furniture R&D, quality assurance, and compliance testing.
