Height-Adjustable Workstation Lets You Move from Sitting to Standing in Just Seconds
This Safe-IT™ drop-leaf tabletop mounts to a solid concrete, masonry or wooden wall to accommodate sitting or standing, whichever is more comfortable for you. With a single touch, the rectangular surface rises or lowers to your perfect height, then locks into place with a turn of the rotary knob. All mounting hardware is included. Height ranges from 29.7 to 47.2 inches (75.4 to 119.9 centimeters).

Large Work Surface Provides Plenty of Room for Your Work Accessories
The surface measures 23.6 x 15.7 inches (60 x 40 centimeters) to hold your laptop, smartphone, USB hub and almost anything else you may need to accomplish your day's tasks. Maximum weight capacity is 22 pounds (10 kilograms). At the end of the workday, the leaf drops down to save space and create a convenient wall shelf. The low-profile workstation blends into any room décor.
