Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Adjustable Arms, model EM-HB-MESH-01, is a professional task chair finished in black. Its tall mesh back forms the main visual element, with a framed resin outer structure and a visible lumbar contour. The curved mesh headrest sits above the backrest and includes a resin shell, soft front padding and visible top trim. Below, the upholstered seat presents a clean rectangular work-chair profile, while rigid T-shaped arm posts and a five-star caster base reinforce its commercial office appearance. Silver-grey inserts on the arms provide subtle contrast against the black frame. Overall dimensions are 660 x 680 x 1290 mm, with 540 mm of clear width between the armrests. Construction combines breathable black woven mesh, molded polyurethane foam, engineered resin and black metal components. The seat uses an 80 mm molded foam pad with black woven fabric or mesh-faced upholstery, and the finished cushion thickness is 90 mm. Backrest padding thickness is 70 mm, and the lumbar support zone height is 240 mm. The armrests use rigid black resin posts with flat padded top pads. Under the seat, a black steel tilt plate with resin cover incorporates a round tension knob and visible lift actuator. A black metal telescoping gas lift connects the seat to the resin or nylon-composite five-star base, which is fitted with casters for movement. Functionally, the chair supports daily computer work through pneumatic seat-height adjustment, a 360-degree swivel, recline control and headrest support. The height lever provides 100 mm of seat-height travel and is intended for compatibility with 760 mm desks. The multi-position tilt mechanism allows the back to recline from 95 to 125 degrees, with lockable upright and reclined positions and three suggested lock positions. A rear under-seat knob adjusts tilt tension to match recline resistance. The stated recommended user weight capacity is 136 kg, and the recommended user height extends to 190 cm. The product facts also list a seat static load verification target of 136 kg and a caster rolling durability target of 100000 cycles. This chair is suited to open-plan offices, private offices, home offices and dedicated workstation settings, particularly for task seating at standard desks. Its mobile base, swivel and adjustable recline make it practical for users who move between keyboard work, calls and relaxed reading positions. For procurement, the chair is unbranded and supplied as one set in two cartons. The reference assembly time is 40 minutes per set. Reference packaged gross weight is 23 kg per set, with carton dimensions of 850 x 420 x 720 mm and a carton volume of 0.26 cubic meters per set. Buyers should plan for two-box receiving, assembly time and final checks of height, tilt, lock and caster operation after installation.
