Adjustable Keyboard & Mouse Tray Under Desk Mount - Ergonomic Desk

In this review of the VIVO Adjustable Computer Keyboard & Mouse Platform Tray, the bottom line is simple: this under-desk tray is for people who want a sturdy, adjustable place for their keyboard and mouse to improve wrist posture without replacing a whole desk. The unit mounts under standard desktops with the supplied hardware and offers 5 in of height adjustment and full side-to-side rotation for comfortable positioning. It is best for home office users or shared workstations that need a compact, retractable surface; users with very thin desks or unusual crossbar frames should check compatibility before buying.

Key Features

• Under-desk mounting: The tray installs under a desk using the included hardware so the keyboard and mouse are tucked away when not in use.
• Adjustable height: A 5 in height adjustment range lets users fine tune wrist angle to reduce soreness and improve ergonomic posture.
• Deluxe 25 in x 10 in tray: The surface accommodates most full-size keyboards and mice while keeping items contained on a generous platform.
• Sliding keyboard track: The keyboard rides on a 14.25 in long by 6.25 in wide track so it can be positioned forward or back for comfortable reach.
• Supportive rubber padding: Rubber padding reduces slipping and offers a softer resting surface for wrists during extended typing sessions.
• Included mounting hardware: All necessary fasteners come in the box for a straightforward assembly and attachment to standard desk thicknesses.

Who It's For

This VIVO tray is ideal for remote workers, freelancers, and office staff who want to free up desktop surface area and reduce wrist strain with an ergonomic under-desk option. Its 25 in x 10 in footprint fits most keyboard and mouse setups and the adjustability helps users tune wrist height and reach.

It is less suitable for desks thinner than the minimum recommended 5/8 in or for some height-adjustable desks that have a crossbar; in those cases the optional spacer accessory is required or buyers should verify fit before purchasing.
