The Ergotron WorkFit-S Single HD Sit-Stand Workstation with Worksurface+ (33-351-211) is an adjustable workstation designed to support a single heavier monitor alongside a keyboard and mouse workspace. Its height-adjustment column lets the user move the monitor and work surface together, making it easier to alternate between sitting and standing positions during the workday.
This model features a bright white finish and an integrated worksurface. The system includes a height-adjustment column, desk clamp, monitor pivot, and keyboard tray, providing a combined solution for creating a more adaptable workstation without replacing the entire desk.
Key Features
- Sit-stand adjustment: Raises and lowers the monitor and keyboard workspace together to support different working positions.
- Heavy-duty monitor support: Accommodates a compatible display weighing 7.3–12.7 kg (16–28 lb).
- Integrated worksurface: Provides a dedicated area for a keyboard and mouse alongside the mounted monitor.
- Desk-clamp installation: Attaches to a compatible desk edge without requiring a floor-standing base.
- White finish: Offers a coordinated appearance for offices, home workspaces, and professional environments.
Adjustable Sit-Stand Design
The WorkFit-S uses a height-adjustment column to move the workstation between sitting and standing positions. The monitor and keyboard tray can travel together through approximately 46 cm (18 inches) of adjustment, while the monitor can also be adjusted independently within its available range.
The monitor pivot provides tilt adjustment to help set the viewing angle. This configuration is intended for one compatible display, with a typical recommended screen size of up to 30 inches. Actual compatibility depends on monitor weight, dimensions, mounting pattern, and available clearance.
Monitor Compatibility
The heavy-duty monitor pivot supports displays weighing between 7.3 and 12.7 kg (16–28 lb). The monitor mounting interface supports VESA MIS-D, MIS-E, and MIS-F patterns, making it suitable for compatible displays with these mounting standards.
The monitor pivot supports approximately 30 degrees of tilt and 90 degrees of screen rotation. Check the display's mounting pattern and physical dimensions before installation to confirm compatibility with the workstation.
Integrated Keyboard Worksurface
The included keyboard tray and worksurface provide a dedicated working area beneath the monitor. Because the monitor and keyboard workspace are connected to the height-adjustment assembly, users can reposition both as a coordinated workstation.
Keep the combined load within the manufacturer's limits. The assembly's maximum load includes the monitor and items placed on the keyboard tray or worksurface, so equipment and accessories must be accounted for when configuring the workstation.
Desk Mounting and Installation
The WorkFit-S attaches to the front edge of a compatible desk using the included clamp. The specified desk-edge thickness is approximately 12–60 mm (0.47–2.4 inches). Before installation, verify the desk thickness, edge construction, underside clearance, and suitability for the workstation's combined load.
Follow the manufacturer's installation instructions carefully and secure the desk clamp fully before adjusting the workstation. Leave enough cable slack for the complete height-adjustment range to prevent cables from becoming stretched or caught during movement.
Typical Applications
- Office and home-office workstations
- Single-monitor sit-stand work areas
- Administrative and productivity environments
- Existing desks requiring an adjustable monitor and keyboard setup
- Workspaces where monitor and keyboard height need to change together
DC Supplies Product Note
Before ordering, confirm that the monitor weighs 7.3–12.7 kg (16–28 lb), uses a compatible VESA mounting pattern, and fits within the recommended display dimensions. Check that the desk edge is compatible with the included clamp and account for the monitor and items placed on the keyboard tray when assessing the workstation's total load.
