Product Description

The YUXIANG EOCH-M62-GRY-FA is a high-back ergonomic office chair designed to balance supportive comfort, durable construction, and understated professional aesthetic for long-duration seated use. Visually, the chair features a cohesive matte grey finish across its structural frame and base, paired with a taut breathable mesh backrest and cushioned seat for a clean, modern silhouette suited to a wide range of interior schemes. The contoured backrest narrows gently at the upper thoracic zone to support natural shoulder movement while widening at the lumbar region to deliver targeted core support, topped with an adjustable headrest to cradle the neck during upright or reclined postures. The five-star base sits low to the floor, fitted with smooth twin-wheel casters for unobtrusive mobility across floor surfaces. Construction utilizes commercial-grade materials built for consistent long-term use: the backrest is upholstered in 100% polyester breathable mesh tested for high abrasion resistance, while the seat cushion uses high-density moulded polyurethane foam with a soft, supportive rebound rate, mounted on a 12mm thick plywood or reinforced polypropylene support pan. Structural components including the frame and armrest shells are made of glass-fiber reinforced polypropylene, with soft polyurethane padding on armrest surfaces for comfortable elbow rest. The height adjustment system uses a Class 3 rated steel pneumatic cylinder, paired with a 2.5mm thick stamped steel tilt chassis; the five-star base is offered in matte grey painted steel or glass-fiber nylon, fitted with 60mm polyurethane twin-wheel casters rated for high rolling durability across hard and soft floor types. Functional features are tailored to flexible, user-centric support: the seat offers smooth vertical height adjustment, with full 360-degree swivel rotation for easy reach across adjacent work surfaces. The backrest tilts with user-adjustable spring tension calibrated to individual body weight, plus an upright lock for stable task-focused positioning. The headrest adjusts both vertically and in pivot angle to suit different user heights, while the fixed contoured lumbar zone integrated into the mesh back maintains consistent lower back support without manual repositioning. Casters roll smoothly across both hard flooring and carpeted surfaces, while armrests sit at a fixed comfortable height above the seat to support forearms during typing or writing tasks. This chair is versatile across both commercial and residential settings, suited for daily 8-hour desk work in open plan or private office workstations, remote work and personal study spaces in home offices, extended meeting seating in conference rooms, single-user task seating, and high-traffic co-working spaces. It is also compatible with height-adjustable sit-stand desks, making it a flexible option for dynamic work setups. It supports individual users up to 150kg for safe, reliable use. For procurement planning, note that each chair ships in two cartons, with a reference assembly time of 40 minutes per unit. The packaged gross weight per set is 23kg, with a carton volume that allows 135 sets to fit in a 20GP container at 85% space utilization, supporting efficient bulk ordering for large workspace fit-outs.
