Built for DIY home-office builders who want to choose their own tabletop, this electric standing desk frame delivers a quiet, programmable sit-stand base ready to pair with a custom 40 in. to 48 in. surface (not included). The desk frame raises smoothly from 27.5 in. to 45.5 in., letting you switch from sitting to standing in seconds, and the high-performance motor lifts at 0.7 in./s while staying under 55 dB so calls and family conversations stay interruption-free. The smart LED controller pairs up and down buttons with a 3-second control lock for child safety, plus 2 memory presets that instantly return the desk to your preferred sitting and standing heights. Built-in overheat and anti-collision shields protect gear and people, while the heavy-duty frame supports up to 155 lb. of monitors, printers, and project materials without sway. Adjustable foot pads keep the base steady on hardwood, tile, and low-pile carpet, and an included hanging hook keeps headphones or bags off the floor. Pair the frame with your favorite tabletop to build a custom workstation that fits your room and style. Color: Black. Material: Metal.
