Manual hand crank sit to stand desk frame lets you shift between sitting and standing work positions without power so you can work more comfortably through the day. The height adjusts from 27.6-in to 45.3-in to match different chairs or preferred working postures. A reinforced steel frame supports up to 110 lbs and pairs with a compatible tabletop, while non-slip foot pads help keep the 41 x 23 in base stable and protect hard floors. The hand crank folds when not in use and installs on either side for flexible setup.
