This desk allows you to alternate between sitting and standing by easily changing its height from 27½ to 47¼ inches using a manual crank handle. The handle can be attached on either the left or right side for flexibility and can be stored under the tabletop when not in use for a tidy appearance. Adjustable feet help keep the desk stable on uneven surfaces. Compatible with SIGNUM cable management, it meets rigorous safety and durability standards for office and public use. Includes a 10-year warranty as outlined in the warranty brochure.
