Details & specifications

Overview & features

A roomy, well-padded desk chair with serious capacity. An S-curve mesh back with adjustable lumbar support, a thick contoured seat, and 90° flip-up arms make it easy to sit comfortably through a long day, then tuck it away.

Why you'll love it

Adjustable lumbar: the support moves about 3.15" up and down and 1" forward and back.
Wide, thick seat: a 20.7" wide seat with a 3.2" high-density foam cushion resists sagging.
Flip-up arms: arms lift 90° to save about a square meter of floor space under the desk.
Rock and relax: a 90° to 125° rocking mode with a tilt lock.
Built for more: a heavy-duty base and gas lift rated to 400 lbs, with double-layer breathable mesh.
