VIVO MOUNT-KB03W Under Desk Keyboard Tray, 25 x 10 in, White, 360° Swivel

Set up a typing station that can move out of the way when your desk needs to serve another purpose. The VIVO MOUNT-KB03W mounts beneath the desktop and lets you position a keyboard and mouse below the work surface.

Its 25 x 10 in platform fits most keyboards and mice. A sliding track lets you pull the tray forward for use and tuck it back under the desk afterward.

Height adjustment, tilt, and full rotation give you several ways to arrange the typing position. The white finish and padded surface complete a practical under-desk setup.

Best use cases

This tray is suited to workstations where keeping the keyboard and mouse on the desktop would take up useful space. Pull the platform out for typing, then slide it beneath the desk when you want a clearer work surface. That makes it a useful format for alternating between typing and other desk tasks.

The 25 x 10 in platform is designed to accommodate most keyboards and mice together. Its track measures 14.25 x 6.25 in, giving the tray room to travel forward and back. Compared with leaving a keyboard fixed on top of the desk, this under-desk design adds a movable typing position that can be stored beneath the work area.

What stands out

The tray offers 5 in of height adjustment, a tilt range from +6° to -22°, and 360° rotation. These adjustments let you change the position and angle of the keyboard and mouse rather than relying on one fixed arrangement. Plush padding adds a softer surface around the typing area, while the particle board and steel construction combines the platform with its mounting structure.

Mounting hardware is included. The desktop must be at least 5/8 in thick for installation, and the tray has a 4.4 lb weight capacity. If installing it on a VIVO height-adjustable desk, the MOUNT-SPACER01 is needed to fit the tray around the desk’s crossbar. A limited 3-year manufacturer warranty is also provided.

What matters most

Before installation, consider the available space beneath the desktop and where the tray will travel as it slides. The platform needs room for both the keyboard and mouse, and the mounted arrangement should suit the desk’s layout. For a typing setup that you want to adjust and put away, the sliding platform offers more flexibility than a stationary keyboard surface.

Buyer feedback highlights straightforward installation and useful movement in different directions. Some buyers also appreciate the tray’s appearance. Experiences are mixed on fit and adjustment, and some report that the tray is stiff to slide or that typing can make the desk move. These practical points make the desk layout and the feel of the mounted setup important parts of choosing an under-desk tray.

Final verdict

The VIVO MOUNT-KB03W is a practical choice for creating a movable keyboard-and-mouse position beneath a desk. Its 25 x 10 in platform, adjustable height and tilt, and 360° rotation support a more configurable typing setup, while the sliding track lets you clear the surface when the tray is not in use. It suits workstations where flexible positioning and an under-desk storage option are the main priorities.
