## Long description

The ergo office ER-403B is an electric height-adjustable sit-stand desk frame in black designed to convert a tabletop into a motorised adjustable desk. Featuring a twin-motor system, the frame provides stable lifting and smooth stepless height adjustment so users can change between sitting and standing positions. The product is intended to be fitted with a compatible tabletop and requires assembly. It is suitable for home and office environments where ergonomic alternatives to fixed desks are needed.
Advantages
The twin-motor mechanism delivers balanced, quiet lifting and improved load capacity compared with single-motor frames. Stepless height adjustment enables precise positioning and more natural transitions between sitting and standing. The black finish offers a neutral appearance that integrates with different tabletop styles. Programmable height positions on supported control units allow quick switching to preferred ergonomic setups.
Suitable for
Home offices where users alternate between sitting and standing
Corporate workstations that require adjustable-height desks for multiple users
Shared spaces and hot-desking environments needing ergonomic flexibility
Workshops or studios where adjustable work surface height improves comfort
Key specifications
Drive: twin electric motors for synchronous lifting
Height adjustment: stepless range suitable for sit-to-stand transitions
Finish: black powder-coated frame
Control: support for programmable positions on compatible control units
Installation: frame-only solution; tabletop and fasteners required
Use: designed for home and office ergonomic applications
How to use
Attach a suitable tabletop to the frame following the included assembly instructions and secure all fasteners. Connect the control unit and power supply according to the wiring diagram provided with the product. Use the control buttons to raise or lower the desk to the desired height; if available, program preferred heights to the memory presets for one-touch adjustment. Verify stability after installation and avoid overloading the surface beyond the manufacturer’s stated capacity.
Usage recommendations
Position the desk so that the monitor top is at or slightly below eye level when standing and at elbow height when sitting. Alternate between sitting and standing throughout the workday, changing posture every 30–60 minutes as needed. Use an anti-fatigue mat when standing for extended periods and ensure cable routing does not obstruct frame movement.
