Submi Office Chair, Mesh Office Chair, Ergonomic Desk Chair for Adults, Computer Chairs with Adjustable Headrest & Flip-up Armrests, Back Support Home Office Task Chair, Work, Comfy, 300LBS, Black

ADVANCED SPINAL SUPPORT STRUCTURE：The Submi office chair features a dual-zone backrest that precisely follows the body’s natural curves. The upper section supports the thoracic spine, while the lower part enhances lumbar support to maintain the spine’s natural S-shape. The adjustable headrest offers multiple height and angle settings, suitable for users of varying heights to provide custom cervical support, reducing neck pressure and fatigue from prolonged sitting.

HIGH-ELASTIC COMFORT CUSHION SYSTEM：The 3.2-inch high-density foam cushion, tested for thousands of pressure cycles, ensures even weight distribution. The 21.2-inch-wide seat balances support and softness to relieve gluteal and coccyx pressure. Height-adjustable armrests can be raised for space-saving storage in compact offices. Unlike mesh, the foam provides a softer, more comfortable seating experience for long-lasting comfort.

BREATHABLE MESH+SPACE AESTHETICS：Rooted in a unique design philosophy, this chair upholds modernist aesthetic purity while adapting to diverse spaces through versatile colour options. The high-elastic mesh with a microporous structure wicks moisture and breathes freely, keeping users cool and comfortable all day. Stain-resistant and easy to clean, it balances design elegance with practical functionality.

INDUSTRIAL-GRADE DURABLE CONSTRUCTION：With an integrated frame tested for 100,000 compression cycles and a 4-stage pneumatic cylinder supporting up to 300 lbs, this chair suits heavy-duty use. Silent casters have undergone 10,000+ mile rolling tests for quiet, smooth movement. Armrest cushions and backrest frames use FSC-certified wood, blending eco-friendliness with structural strength for commercial and home environments.

EFFORTLESS ASSEMBLY AND WORRY-FREE AFTER-SALES SERVICE：With clearly labelled components and an illustrated manual, assembly takes just 15–20 minutes. English and French bilingual round-the-clock online support offers lifetime after-sales service, including a 6-month free replacement for gas springs, armrests, and casters, ensuring a seamless user experience through comprehensive support.
