产品描述

The Black Split-Back Ergonomic Office Task Chair (model TASK-SB-FA-001, unbranded) is a streamlined, no-headrest mid-back task seating solution designed for flexible use across commercial and residential work spaces. Its understated all-black profile creates a clean, cohesive visual that integrates seamlessly with neutral decor palettes, while its compact footprint supports efficient layout planning in shared environments. Constructed for long-term regular use, the chair pairs black breathable woven mesh and fabric upholstery with a fiberglass-reinforced PP/nylon back support frame. Its seat cushion uses 40D high-density polyurethane foam for consistent support, finished with tight, uniform stitching. The structure is anchored by a black reinforced nylon five-star base fitted with black PA dual-wheel hard floor casters, connected via a chrome-plated Class 3 rated steel gas lift. A 2.5mm thick powder-coated stamped steel tilt mechanism provides core structural stability, while fixed rigid PP armrests with flat hard top surfaces offer consistent upper limb support aligned to standard desk heights. Functional features are tailored to seated comfort and ease of use: full 360-degree swivel rotation enables easy access to surrounding work surfaces, pneumatic seat height adjustment delivers vertical travel via a convenient side lever, and a spring-loaded tilt function allows 12-degree rearward recline with a lock for upright working positions. The signature split dual upper back support uses two separate padded panels to evenly distribute upper back pressure, paired with an integrated contoured fixed lumbar pad aligned to the natural lower back curve for sustained posture support during long seated sessions. The dual-wheel casters roll smoothly across hard flooring and low-pile carpet common in office settings. This chair is well suited for home office workstations paired with standard height desks for daily remote work, open plan office cubicles where high-density seating arrangements are required, small meeting rooms where quick repositioning supports collaborative discussion, student study desks for extended homework and study sessions, reception and admin areas requiring consistent, decor-friendly seating, and co-working hot desks serving diverse user groups. Procurement teams should note the chair ships in two cartons per set, with a reference assembly time of 40 minutes per unit, and is packaged to support efficient bulk shipping for large fit-out projects. The fixed armrest height and non-adjustable lumbar support should be aligned with intended user needs and existing desk dimensions prior to purchase, and its weight capacity supports use across a broad range of adult users.
