Upside worksurfaces can integrate into panel-based or freestanding applications. Ample leg room is the result of a proprietary Three H design using custom fittings which eliminate the need for base feet in panel configurations. Two adjustable mechanisms are available: The 2 stage leg option offers a range of 26-45 inches. While the 3 stage offers a range of 23-49 inches in height, it also features an LED display indicating current height and 3 memory positions – adapting to individual needs. Built-in to the 3-stage model, is an anti-collision sensor that prevents material damage to the desk in case of collision.
