If you spend hours at your desk, this HON task chair is about to make your workday so much more comfortable! The four-way stretch mesh back is genius - it cradles your spine naturally while allowing air to circulate so you don't get all hot and sweaty. The synchro-tilt mechanism is smooth and intuitive, reclining the back and seat together in the perfect ratio for natural posture whether you're sitting upright or leaning back. The adjustable lumbar support lets you customize the lower back comfort exactly how you need it. The arms are both height and width adjustable, so you can position them perfectly for your body and desk setup. The seat height adjusts pneumatically from 17 to 21 inches, and the 360-degree swivel gives you full mobility. With a 300-pound weight capacity and 19-inch wide seat (with 16-18 inch depth adjustment), it accommodates most body types comfortably. The five-star base with hard dual-wheel casters rolls smoothly on most floor surfaces. The black fabric upholstery on the cushioned seat pairs well with the black frame for a professional look that fits any office decor. If you're tired of uncomfortable office chairs that leave you achy by the end of the day, this HON chair delivers the ergonomic features and quality construction that make long work sessions actually bearable.
