A good office chair can be beneficial to a productive workday. Imagine sitting on a hard leather seated, lack-of-maneuverability, unadjustable, weak back-and-lumbar-supportive office chair, I suppose you won’t have a very comfortable working experience, nor a good efficiency, not to mention a pleasant mood. Adjustable seat height: The seat height of this computer mesh chair can be simply adjusted from 31.5cm to 41.5cm by a little push-up/press down at the lever under the seat according to your needs. Reclining office chair: By simply pushing the lever or pulling it out, this mesh office chair can be tilted and leaned backward or locked in place for your various sitting positions. A tilt tension control knob under the seat is provided to adjust the recline angle. Robust chair construction: This mid-back office chair is constructed of hard-wearing nylon mesh, durable starbase, solid rolling casters, and an SGS-certified gas cylinder. It has passed the BIFMA X5.1 Test and is recommended for office use for customers under 100kg. Starbase & 360 degrees wheels: Twisting and turning about is integral within the office. So adopt a stable star base and equip it with 5pcs 360-degree swivel wheels, ensuring fluent and quick movement and keeping up your quick pace of work. Larger seat for optimal comfort: In this model, the seat size is upgraded, measuring 52.5cm(width) by 51cm depth, and 7 cm thick to provide you with a softer and larger sitting area.
