Mesh Chair With Adjustable Armrests

The Ergonomic Mesh Task Chair with Adjustable Armrests (Model: EM-402) is engineered for high-density corporate workstations and commercial spaces. Built to comply with ANSI/BIFMA X5.1 (North America) and EN 1335 (Europe), it balances structural durability with dynamic lumbar support. Designed for volume distributors and contract furniture brands, the modular architecture streamlines assembly, reduces shipping volume via knock-down (KD) packaging, and withstands multi-shift commercial usage.
