Product Description

YUXIANG’s OFC-MBW-620W-GRY mid-back mesh office task chair pairs a streamlined minimalist aesthetic with functional ergonomic support for versatile seating across professional and residential settings. Its visual profile is defined by a crisp white structural frame paired with neutral grey upholstery, creating a clean, understated look that blends seamlessly with contemporary interior palettes. The fixed integrated loop armrests curve gently to match the frame’s finish, while the mid-height mesh backrest and contoured seat create a balanced, compact silhouette suited to space-conscious layouts. The chair is constructed with durable, purpose-built materials selected for long-term regular use. The back frame and armrests are made from white fiberglass-reinforced polypropylene, paired with a breathable grey polyester mesh backrest that incorporates a built-in contoured lumbar section for targeted lower back support. The seat features a 12mm thick curved plywood support board, topped with 70mm thick high-density polyurethane foam and upholstered in hard-wearing grey woven polyester fabric. The five-star base is crafted from white reinforced polypropylene, fitted with 60mm diameter dual-wheel black polyurethane casters suitable for hard floors and low-pile carpet. Core functional components include a Class 3 black steel pneumatic gas lift cylinder, a 2.5mm thick stamped steel tilt mechanism plate, and durable hardware engineered to withstand repeated daily operation. Practical functionality is designed for flexible work patterns. The chair offers full 360-degree swivel rotation around its central axis, with pneumatic seat height adjustment delivering 100mm of vertical travel controlled via a side-mounted lever, reaching a maximum seat height of 540mm. The backrest reclines to a 125-degree lockable angle, with an adjustable tension knob to customize recline resistance for individual user preference. The fixed armrests sit 210mm above the seat to provide consistent arm support, while the smooth-rolling casters enable easy repositioning. The chair ships in knock-down form, with all required hardware included for assembly without specialized tools. This model is well suited for a range of spaces. Its compact footprint fits small home office desks and apartment work areas, while its durable construction supports 8-hour daily use at open-plan office employee workstations. The neutral white and grey finish coordinates easily with modern interiors in small meeting and conference rooms, and the adjustable height accommodates growing users in student study spaces. The swivel and rolling functionality also makes it a strong fit for hot-desking shared workspaces, where quick repositioning is a frequent need; it pairs effectively with executive desks up to 2.4m in width. For procurement planning, note the chair has a recommended static load capacity of 120kg and is designed for users up to 180cm tall. Each unit is shipped across two cartons, with a total packaged gross weight of 23kg per set, and assembly time of 40 minutes per chair. Bulk orders should account for these packaging and assembly requirements when coordinating delivery and workspace setup.
