Our series of anti-fatigue mats for standing desks, reception areas, and fixed standing workstations includes PVC flat, 12mm/19mm thickened, PU balance, and round cork styles. Before purchasing, please measure the available width and depth in front of your desk, as well as the movement range of chair legs and pathways. Different flooring types, dust, moisture, and cleaning agents can affect friction; please test the mat in its actual intended location before use. These mats are workstation accessories, not medical devices; for prolonged work, it is still recommended to regularly change posture and take breaks. All styles will be checked at our Hong Kong warehouse for dimensions, surface, edges, and flatness before dispatch.
