Product Description

The High-Back Burgundy Executive Office Chair, model EOCHB-BUR-5STAR-01, is an unbranded executive seating option with a formal, structured appearance. Its tall burgundy upholstered back combines a smooth padded lower-back panel with a diamond-embossed upper insert, giving the chair a traditional executive look while maintaining a coordinated visual finish. The padded seat, black arm pads, black mechanism components, polished metal five-star base, and black twin-wheel casters create a clear contrast between the burgundy upholstery and the dark functional elements. The fixed arm layout provides a clear width between armrests of 540 mm, and the chair’s 690 mm-wide footprint supports placement in dedicated desk areas without a separate headrest accessory. Construction is built around shaped foam and reinforced internal framing. The seat uses a 90 mm molded polyurethane cushion with a procurement density of 45 kg/m³, while the backrest uses 70 mm contoured polyurethane padding with a procurement density of 35 kg/m³. The 240 mm lumbar support zone is integrated into the padded back. Inside, the seat carrier uses 15 mm plywood or molded composite with steel reinforcement, and the back support uses a 1.5 mm steel tubular or stamped inner frame. Arm pads are black molded polyurethane or polymer with rounded front edges, supported by black die-cast or glass-reinforced nylon vertical supports. The chair supports a full 360-degree swivel and pneumatic seat-height adjustment through an under-seat paddle, with 80 mm of vertical travel. A single-lever synchro-tilt mechanism provides an 18-degree maximum recline, with multi-position tilt lock settings at an upright 100-degree position and a 118-degree full-recline position. A rotary tension knob adjusts resistance for occupant weight up to 150 kg. Five 60 mm twin-wheel casters provide omnidirectional movement, and the chair is recommended for users up to 150 kg and 185 cm in stature, with an eight-hour daily-use duration. The caster rolling durability target is 100000 cycles. This model suits private executive offices, open-plan workstations, meeting and conference rooms, hotel or club business centers, and home offices. In meeting settings, it offers padded support for gatherings lasting up to three hours. For multi-site procurement, select soft twin-wheel tread for hard floors and hard tread for carpet. Buyers should also note the chair ships as one set in two cartons, with a reference assembly time of 40 minutes per set, a net weight of 21 kg, and packaged gross-weight references of 23 kg and 24 kg.
