Adjustable Keyboard and Mouse Tray Under Desk Mount - Smooth Rolling

In this review of the VIVO under-desk keyboard and mouse tray mount, the bottom line is simple: it is for desk users who want a stable, adjustable under-desk sliding platform to improve typing posture and free desktop space. The tray's strongest selling point is its deluxe rolling 18' track for smooth in-and-out movement combined with multiple adjustment axes, which delivers a noticeably more ergonomic setup for long typing sessions. Assembly is straightforward and the included hardware makes it practical for most desks that can support the under-mounted weight.

Key Features

• Deluxe sliding track: The 18' rolling track lets the keyboard platform slide smoothly forward and back so the tray tucks neatly under the desk when not in use.
• Extensive adjustability: The mounting offers up to 40 degree tilt, 40 degree swivel, and 6.7' of height adjustment so users can dial in a comfortable angle and elevation.
• Plush wrist support: Gel padding across the front edge reduces wrist pressure during typing and helps alleviate soreness over long sessions.
• Generous tray size: The 26.5' x 10' universal tray accommodates most full-size keyboards and mouse pads with room to position peripherals.
• Simple installation: All necessary mounting hardware is included and instructions are clear, making under-desk attachment straightforward for DIY installation.
• Backed warranty: A 3 year limited manufacturer warranty provides added confidence and access to tech support if issues arise.

Who It's For

This tray is aimed at office workers, remote employees, and students who want to improve ergonomics and reclaim desk surface area without replacing furniture. It suits people who prefer an under-desk solution that can be tucked away and who need adjustable tilt and height to reduce wrist and shoulder strain.

It is less appropriate for users with very thin or fragile desks that cannot support the total mounted weight, or desks that lack 18' of clearance along the mounting path. Also, shoppers wanting a permanently fixed, heavy-duty metal industrial drawer may want to consider alternate heavy-load drawer systems.

Pros & Cons

Pros

• Smooth, reliable sliding action on the deluxe 18' track for easy stow and deploy.

Cons

• Tray weight and mounting load require a desk that can support about 10 to 12.65 lbs under-mounted, which excludes some lightweight furniture.
• Some users report mixed impressions of build solidity and occasional unwanted tilt movement under load.
