Description

Logic 1780 High-Back Task Chair with Arms: Ergonomic support for all-day sitting

Ratchet lumbar, pneumatic height and smooth mobility

Product Overview:

Look, if you sit at a desk all day and your back grumbles by mid-afternoon, this chair understands you. The Logic 1780 brings a waterfall seat and ratchet lumbar that steer your posture toward comfort, not pain. Pneumatic height and adjustable arms get you lined up with your desk, while the tilt lock and tension let you sit upright or ease back without surprise. The five-star base rolls smoothly, and the upholstered polyester wipes clean faster than you expect. It's Greenguard certified, designed for an eight-hour day, and built for straightforward adjustment so you get on with work, not fiddling.

Key Features:

  • Tilt Lock: Locks the recline where you want it, so posture stays steady during long work sessions.
  • Tilt Tension: Center knob adjusts resistance smoothly, so you feel controlled leaning without sudden drops or fuss.
  • Tilt Angle: Six-degree forward tilt and infinite back-angle adjustment lets you fine-tune focus and recline precisely.
  • Stain Resistant: Upholstered polyester resists spills and cleans up quickly, so the chair looks sharper day after day.
