Built for extended desk use with a 90–120° rocking\/recline mechanism and stable fixed armrests. Available in Grey.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContoured lumbar support reduces lower back strain during long sitting sessions\u003c\/strong\u003e – The mid-back design follows the natural inward curve of the lumbar spine. Maintaining this curve while seated reduces the tendency to slouch forward, which is a primary cause of lower back fatigue and discomfort during extended desk work. The support is built into the backrest structure rather than added as a separate adjustable component.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreathable mesh back prevents heat and moisture buildup\u003c\/strong\u003e – The open mesh structure allows continuous air circulation behind your back throughout the day. Unlike solid foam or upholstered backrests that trap heat, the mesh keeps the contact surface ventilated, reducing sweat accumulation during long work sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-resilience foam seat maintains its shape under daily use\u003c\/strong\u003e – The seat cushion uses high-resilience foam, which is denser than standard polyurethane foam and resists the gradual compression that causes cheaper chairs to flatten and lose support over months of use. The cushion stays firm enough to support proper seated posture without bottoming out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90–120° recline with adjustable tension knob allows controlled posture changes\u003c\/strong\u003e – Holding a fixed seated posture for extended periods increases cumulative spinal load. The recline mechanism lets you shift weight backward and decompress the spine periodically, while the tension knob allows you to calibrate recline resistance to your body weight so the chair responds predictably.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed armrests provide consistent, stable arm support\u003c\/strong\u003e – Unlike flip or height-adjustable armrests, fixed armrests stay in a set position, which provides a reliable resting surface for the forearms during typing or mouse use. This suits users who prefer a consistent reference point for arm placement rather than adjustable positioning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBIFMA-certified gas lift ensures safe, reliable height adjustment\u003c\/strong\u003e – The pneumatic gas cylinder meets BIFMA (Business and Institutional Furniture Manufacturers Association) certification standards, which include load capacity, durability, and safety testing under repeated use cycles. The seat height adjusts from 16.7\" to 19.7\" to accommodate a range of desk heights and body types.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e360° silent swivel casters protect hard floor surfaces\u003c\/strong\u003e – The casters are designed to roll quietly without scratching hardwood or tile floors, unlike standard hard plastic casters that can leave marks or produce noise on hard surfaces. The 360° swivel allows free movement in any direction without repositioning the chair.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear storage pocket keeps the workspace clear\u003c\/strong\u003e – A built-in pocket on the back of the chair holds books, tablets, documents, or small items within reach without requiring a separate desk organizer or side table.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArmrest type:\u003c\/strong\u003e Fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat height range:\u003c\/strong\u003e 16.7–19.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecline range:\u003c\/strong\u003e 90–120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight capacity:\u003c\/strong\u003e 250 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembled dimensions:\u003c\/strong\u003e 22.24\" L × 21.46\" W × 38.19\" H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct weight:\u003c\/strong\u003e 21.61 lbs (9.8 kg)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage dimensions:\u003c\/strong\u003e 21.65\" × 9.84\" × 18.11\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage weight:\u003c\/strong\u003e 25.35 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem No.:\u003c\/strong\u003e ZHUMI-C-5512CZ-GY\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 × Mid-Back Office Chair (assembly required)\u003c\/li\u003e\u003c\/ul\u003e","brand":"CJ Dropshipping","offers":[{"title":"Grey.Fixed handrail","offer_id":51835955282200,"sku":"CJJT27148200001","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0924\/4760\/5016\/files\/f0c4c7e7-ad2f-40d1-a65f-ba13773ffb82.jpg?v=1773932160","url":"https:\/\/bodyallianceshop.com\/products\/ergonomic-mid-back-mesh-office-chair-lumbar-support-fixed-armrests-grey","provider":"Body Alliance Shop","version":"1.0","type":"link"}
