The Vinsetto Dark Grey High-Back Executive Office Chair, model 920V70CG, presents a formal desk-chair profile with a tall upholstered back, integrated headrest zone, and fixed padded block arms. Its dark grey smooth PU leather covers the seat, back, and armrest pads, giving the chair a coordinated executive appearance suited to private offices and professional meeting spaces. A polished metal-look five-star base, black-sleeved gas-lift pedestal, and twin-wheel casters complete the visual form while supporting swivel and rolling movement. The chair measures 700 mm wide, 710 mm deep, and 1210 mm high overall, with a 530 mm by 550 mm seat, a 700 mm high backrest, and a shoulder-zone width of 520 mm. The integrated upper-back cushion measures 500 mm wide by 180 mm high and provides passive head and neck support without a separate moving headrest. Construction combines molded polyurethane foam with a supportive internal structure. The seat uses 100 mm thick molded foam at its front edge, while the contoured back includes 80 mm thick lumbar and shoulder padding. The foam specification targets 32 kg/m3 density and 35 percent rebound. Inside, the seat has a 12 mm molded plywood or equivalent composite load board, and the back uses a 20 mm tubular steel or bent plywood subframe. The armrests feature soft upholstered pads over rigid supports, and the center pedestal uses a 50 mm diameter steel gas-lift column. The radial base has a 2.0 mm equivalent section thickness, and the chair has a net weight of 17.5 kg. Daily-use functions focus on ergonomic adjustment and mobility. A lever under the seat provides 80 mm of pneumatic height travel, from 460 to 540 mm. The back supports a 15-degree backward rocking motion, with a single-position upright lock and an adjustable tension knob intended to tailor rocking resistance. Fixed armrests offer an 820 mm floor-to-pad support height and move with the seat. Five twin-wheel casters are intended for wood, tile, and low-pile carpeted floors. The maximum user weight is 135 kg, and the chair is recommended for eight hours of use per user. This model is appropriate for executive offices, home studies, open-plan workstations, and meeting or video-call rooms. Its 700 mm width and dark grey finish suit dedicated desks, while swivel and caster mobility support movement between nearby work zones. Procurement planning should account for one set supplied across two cartons, 23 kg packaged gross weight, 0.26 cubic meter carton volume, and an assembly time of 40 minutes per set.
