Hi! We are pleased that you appreciate the quality of our office chairs. The K1T-WH-01 chair is designed for employees working in office environments. It features a simple design with various functions tailored for everyday work, and its ice silk mesh design provides enhanced comfort and coolness. If you are taller, we recommend trying our T3 T2 X7 models, which offer adjustable extended backrests and sliding seat functions. These features help make our chairs larger and, we believe, better suited for your needs.
