This Cutting Table with Grid allows you to adjust the height of the legs of the large, expanding top to the perfect height for you to alleviate back pain. Adjusts between 76.84 - 99.70 cm (30.25" – 39.25"). The sewing grid includes inches, centimeters, angles, and radial lines for your quilting or sewing projects. The storage bins under the center top keep your tools available but off the top for more work space. The casters make it easy to move around to free up space in your sewing studio. The side panels easily fold down for quick storage when not in use. This item is supplied flatpack, and will need a screwdriver for assembly.
