2. SumLush Fit CC Ergonomic Chair As a representative of high cost-effectiveness among domestic products, the Fit CC is referred to as a 'Herman Miller alternative' by some users. Its core advantage lies in multiple ergonomic designs: the chair back adopts a bionic S-shaped curve, combined with an adjustable lumbar support to precisely support the lumbar spine; the seat uses high-density foam to disperse pressure on the buttocks; the headrest supports up-and-down and angle adjustments to fit different sitting postures. In addition, this chair is equipped with 3D armrests (adjustable up and down, forward and backward, and in angle) and breathable mesh fabric, enhancing comfort during long-term use. The price is usually in the range of 1000-2000 yuan, suitable for users with a limited budget but seeking functionality.
