Crank Adjustable Standing Desk is a proven customer pleaser, year after year. Combine it with our adjustable-height dual monitor shelf, and you have an ergonomic workspace with plenty of usable storage. Specifically, the shelf raises your screens to the perfect height for comfortable viewing while simultaneously opening up room underneath for desktop items like your stapler, tape dispenser, pencil cup, and more. Additional features include lockable casters for mobility plus a smooth and reliable hand crank height adjustment. The crank can be positioned on either side of the desk so that you can work around walls and other obstacles. Inbox Zero is based in the suburbs of Chicago.
