Yaheetech Office Computer Chair Mid Back Adjustable Desk Chair with Lumbar Support Armrest Swivel Rolling for Home Office Study Blue

Ergonomic Backrest Design: Curved backrest can perfectly line up with human body curve and support your spine’s natural curve. The lumbar support system resembles a pair of hands, pushing up and holding your low back.

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.

Robust Chair Construction: This mid-back office chair is constructed of hard-wearing polyester mesh, high-density foam, durable star base, solid rolling casters and SGS-certified gas cylinder. It has passed BIFMA X5.1 Test and is recommended for office use for customers under 136kg.

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.

Star Base & 360 Degrees Wheels: Twisting and turning about is integral within the office. So we adopt a stable star base and furnish it with 5pcs 360-degree swivel wheels, ensuring fluent and quick movement and keeping up your quick pace of work.
