The Mid-Back Mesh Swivel Office Task Chair with Fixed Height-Adjustable Armrests is a versatile task seating solution with a streamlined, professional appearance anchored by its all-black woven fabric seat and contoured mesh back, supported by a polished chrome-plated five-star base. The unified, space-efficient layout positions components to support natural seated posture without excess bulk, making it a flexible fit for a range of work environments. Constructed for consistent daily use, the chair features a tensioned breathable nylon mesh backrest set over a rigid PP structural frame, paired with a padded seat built on a bent plywood support core layered with high-density polyurethane foam and upholstered in woven black fabric. Height adjustment is enabled by a Class 3 chrome-plated steel pneumatic gas lift, connected to a reinforced steel tilt and height control chassis mounted beneath the seat. Rigid T-shaped PP armrests attach via height-adjustable chrome steel support posts, while the base is fitted with dual-wheel PU soft casters designed for smooth movement across both hard and soft floor surfaces. Core functional features support comfortable, practical workday use: the mesh back delivers contoured lumbar support to encourage upright posture, while the seat’s waterfall front edge reduces pressure on the legs during extended sitting. A side-mounted pneumatic lever controls smooth seat height adjustment, and the chair offers 360-degree unlimited swivel rotation alongside a spring-loaded back tilt with adjustable tension, allowing up to a 125-degree recline. The fixed armrest height is calibrated to align with standard desk work surfaces, eliminating unnecessary adjustment steps for regular task work. This chair is well suited for open office workstations, where it supports 8-hour daily staff use at standard-height desks, as well as compact home office setups for computer and desk work. It also functions effectively in meeting and conference rooms for short to medium-length gatherings, training spaces where easy repositioning supports group activities, and front reception areas where its polished professional appearance aligns with customer-facing work zones. Procurement teams should note that each unit ships across two cartons, with a typical assembly time of 40 minutes per chair. The compact footprint allows for optimized container loading for bulk orders, and the chair’s design is calibrated to pair with standard work surfaces, including larger executive desk formats.
