This electric sit-stand desk provides a style alternative to the common height-adjustable desk design; while still providing the same height-adjustment functions; convenience; and benefits. The desk legs use sleek slanted lines; instead of the usual center-aligned vertical legs to allow for some differentiation from the purely utilitarian aesthetic typically used in motorized desks. This desk frame also has built-in casters to help with moving or repositioning the desk. The casters extend at the lowest desk height setting and then retract once the desk legs are extended to ensure safety and stability when in use. Although the desk is not designed for mobile use; the casters do help when the desk has to be relocated by a single person. This sit-stand desk frame helps boost productivity by improving comfort and well-being. Get the full benefits of a height-adjustable desk by changing positions throughout the day and by mixing in some standing periods to break the monotony of seated office work. The desk is easy to adjust and is raised and lowered using a fast; quiet; and powerful electric motor to help users comfortably work while sitting or standing. The control panel has user-programmable height presets for one touch operation. The frame is made of quality powder-coated steel for stability and durability.
