Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest, model OE-HBM-650-GR, presents a professional, understated design through its coordinated grey and black finish. The tall backrest and matching headrest use grey flexible mesh stretched over a black framed structure, supporting a light, open visual profile while providing distinct lumbar and upper-back zones. The grey upholstered foam seat softens the appearance, while black fixed T-shaped armrests, a black support frame, and a five-star radial base give the chair a structured commercial look. The swivel base places twin-wheel casters at the end of each spoke, reinforcing mobility and a balanced desk-chair silhouette. Construction combines a breathable mesh back and mesh-faced padded headrest with a grey upholstered foam cushion set over a rigid seat shell. The finished seat cushion is 90 mm thick and uses 45 kg/m3 foam, while the backrest includes 70 mm of padding thickness and a 240 mm high lumbar support zone. Armrests are black rigid fixed structures with rectangular pads, and the clear width between them is 540 mm. The support frame is offered in black painted steel or nylon, paired with a nylon five-star base and black twin-wheel swivel casters. Functional features are tailored to regular desk-based work. A pneumatic seat-height lift provides 100 mm of travel through an under-seat lever, and the synchro-style tilt mechanism allows 18 degrees of rearward movement with adjustable tension. A rear under-seat lever controls the three-position tilt lock, helping users choose between free movement and secured postures. The padded headrest pivots and offers 80 mm of vertical adjustment for neck support. The chair is rated for users up to 136 kg and is recommended for daily use up to 8 hours, with caster rolling durability and gas-lift height adjustment each verified to 100,000 cycles. The back mesh has undergone a 120 N static pull test. This model is well suited to open-plan offices, home offices, and administrative workstations where high-back support, breathable mesh, fixed arm support, and rolling mobility are required. It is particularly appropriate for single-shift desk use rather than shared around-the-clock seating programs. Procurement teams should note the unbranded product presentation and confirm frame material, finish consistency, assembly details, replacement parts availability, and warranty terms before volume purchase. Each set is supplied across two cartons with a packaged gross weight of 23 kg and a reference assembly time of 40 minutes. Overall dimensions are 650 x 650 x 1280 mm, and the reference carton volume is 0.26 m3 per set, making delivery access, storage space, and installation planning useful parts of the specification review.
