DUMOS 1411-H3-KA-22 Ergonomic Office Chair, Mesh Back, Lumbar Support

For a home office, study area, or meeting room, this chair combines a breathable mesh back with a contoured mid-back design and lumbar support. Its adjustable seat height helps you set up a more comfortable position at your desk.

Fixed armrests provide a steady place to rest your arms, while the 360-degree swivel and rolling casters make it easier to move between tasks. The black finish fits naturally into a work or study space.

When you want a change from an upright working position, the rocking recline tilts from 90° to 120°. Adjust the tension knob to change the recline resistance for a more relaxed break at your desk.

Getting the most from it

This chair is designed for indoor desk use, including office work, studying, computer tasks, gaming, and meetings. The mesh back allows airflow around the backrest, while the foam seat provides a cushioned place to sit. Lumbar support and the contoured mid-back shape add support where it matters during everyday desk activities.

Compared with a basic fixed-position task chair, the rocking tilt gives you another way to shift posture during a break, and its tension knob lets you adjust how readily the chair reclines. If you prefer a mid-back profile with fixed arms rather than a larger high-back design, this format keeps the seating setup focused on desk use. Buyers often praise the chair’s comfort and straightforward assembly, feedback on adjustability is mixed, with some appreciating the adjustable seat height and others wishing the back sat higher.

Usage tips

Set the seat height so your position feels comfortable at your desk, using the 14.7-to-17.7-inch adjustment range. The fixed armrests stay in place, so position the chair with them in mind when pulling up to a desk or table. For a rocking break, use the tilt mechanism and turn the tension knob to adjust resistance. The casters support movement around an indoor workspace, and the mesh upholstery can be wiped clean as needed.
