★★★ 24-Hour Free Shipping Prime Service ★★★. 【Breathable Mid-back Design】Featuring densely knitted mesh backrest, this mesh office chair allows better airflow, accelerating heat and moisture dissipation. Mid-back design supports your spine's natural curve and protects your lower and middle back as it prompts you to sit straight. 【Larger Seat for Optimal Comfort】In this model, we upgraded the seat size, measuring 52.5cm/20.7’’ (width) by 51cm/20’’ (depth), and 7cm/2.8’’ thick, to provide you with a softer and larger sitting area. 【Adjustable Seat Height】The seat height of this computer mesh chair can be simply adjusted from 35cm/13.8’’ to 45cm/17.7’’ by a little push-up/press down at the lever under the seat according to your needs.
