Adjustable Corner Keyboard and Mouse Tray for L-Shaped Desks

In this review of the VIVO corner keyboard and mouse tray, the bottom line is simple: it is a practical under-desk solution for people who need an ergonomic typing position on an L-shaped workstation. The tray's corner connector lets the track mount directly in a corner, saving desk edge space while offering height adjustment and full rotation so wrists and shoulders can be positioned more naturally. It suits users who want an unobtrusive, tool-free adjustable platform for a full-size keyboard and mouse without changing their main desktop surface.

Key Features

• Corner connector: The 16.8 in x 9.8 in corner plate secures the tray under an L-shaped desk so the track mounts directly in the corner for a clean installation.
• Deluxe tray size: The 25 in x 10 in tray accommodates most full-size keyboards and mice while the sliding track provides 14.25 in of travel for comfortable reach.
• Ergonomic adjustments: The platform offers 5 in of height adjustment plus tilt and 360 degree rotation so users can fine-tune wrist angle and arm posture.
• Smooth sliding track: The tray glides on a 14.25 in long by 6.25 in wide track for easy forward and backward positioning and stowing under the desk.
• Sturdy construction: A steel connector and frame are supplied with mounting hardware and a limited 3-year manufacturer warranty for long-term support.

Who It's For

This tray is best for people who use L-shaped desks and need an under-desk solution that maximizes corner space while allowing a full-size keyboard and mouse to be stored out of the way. It is particularly useful for workers who want posture improvement through height and tilt adjustments and who prefer a platform that swivels away when not in use.

It may not be ideal for very lightweight or fragile desks that cannot support the total mounted weight of the tray assembly, and users with very thick desktop material should check compatibility, since maximum recommended desktop thickness for the corner connector is 1.4 in. Those who need an ultra-rigid, vibration-free solution should note mixed feedback about stability from some customers.

Pros & Cons

Pros

• Corner plate design allows mounting directly in an L-shaped desk corner for efficient use of space.
• Large 25 in x 10 in tray fits full-size keyboards and provides generous mouse area.
• Multiple ergonomic adjustments including 5 in height range, tilt, and full rotation improve comfort.
• Comes with mounting hardware, clear instructions, and a 3-year warranty for support.

Cons

• Some users reported the tray felt wobbly after installation, so stability can depend on desk construction and installation care.
• The tray assembly adds weight under the desk; verify your desk can support the mounted weight before installation.
