Height-adjustable from 27.5-42 in, this sit to stand rolling computer desk lets you change posture during work to reduce pressure on your spine. A gas rod lifting mechanism raises or lowers the tabletop smoothly and quietly so you can adjust height without disturbing others. The steel frame and stable base support up to 66 lbs to hold a computer, notebook, and accessories securely. A 37.5 x 21.5 in work surface made of MDF and PVC offers room for everyday tasks and wipes clean easily. Four low-noise wheels move the desk wherever you need it at home or in the office, and rounded corners with an ergonomic front edge provide a more comfortable approach while helping reduce bump injuries.
