Product Description

The YUXIANG High-Back Ergonomic Mesh Office Chair, model ERG-MSH-FXARM-590, is a purpose-built seating solution engineered for extended daily use across professional and residential settings. Its streamlined, functional silhouette features a tall supportive backrest paired with a height- and angle-adjustable headrest, fixed curved armrests that connect seamlessly between the seat and back frame, and a classic five-star base configuration that creates a stable, balanced footprint suited to standard desk layouts. Constructed for long-term durability, the chair pairs a breathable tensioned polyester mesh backrest set over a PP reinforced frame with a matching mesh headrest surface mounted to a curved PP support, promoting consistent airflow to reduce heat buildup during long work sessions. The seat rests on a 12 mm thick plywood internal base, topped with a 50 mm thick high-density foam cushion upholstered in breathable fabric for balanced comfort and support. Core structural components include a Class 3 steel gas lift cylinder, a 3 mm thick steel butterfly tilt plate with tension adjustment, a reinforced nylon five-star base, and 60 mm diameter mute nylon twin-wheel casters. The chair supports a maximum static load of 200 kg, with a net weight of 18 kg. Practical, user-centric functions support adaptable comfort for diverse users: pneumatic seat height adjustment is operated via an under-seat lever, the butterfly tilt mechanism enables a 125-degree recline with a lockable upright position, and an adjustable tension knob modulates recline resistance to match individual user weight. A full 360-degree swivel allows easy access to surrounding desk surfaces without repositioning the base, the adjustable headrest provides targeted neck support during reclined positions, and a contoured integrated central lumbar support maintains healthy lower spine alignment. The smooth-rolling casters move easily across both hard flooring and carpeted surfaces. This chair is well suited for a wide range of spaces, including corporate open office workstations aligned with standard 760 mm desk heights, home office setups for daily full-shift computer work, conference and meeting room participant seating, high-traffic co-working shared desks, private managerial offices requiring extended-session upper back and neck support, and residential study areas serving teen and adult users for schoolwork or personal projects. Procurement teams should note the product ships as one set across two cartons, with a reference assembly time of 40 minutes per unit, and packaged weight of 23 kg per set, with 135 sets fitting in a 20GP container at 85% space utilization, supporting efficient bulk ordering for large space fit-outs.
