Overview

Why Choose EC300

The EC300 is engineered for taller users who need full back support. Unlike chairs with separate lumbar adjustment, the EC300's entire backrest—including lumbar support—moves together through 5 height positions (2.36" total range), ensuring integrated support across your spine. Designed for users from 5'4" to 6'1" and up to 220 lbs, it pairs this unified backrest with a 5-position sliding seat (1.97" adjustment), a 3D headrest with height, depth, rotation and pivot control, and 2D height-adjustable armrests.

With 4 recline lock positions (90°, 105°, 120°, 130°) and an adjustable tilt tension knob, you can switch from focused work to reading or relaxing. The breathable soft-touch mesh, 55D high-density foam cushion, SGS Class-4 gas lift, and silent 2.36" casters deliver durable, quiet performance for home office and professional workspaces alike.
