Sit Stand Keyboard Tray, Height Adjustable Under Desk Keyboard

In this review the Mount-It! Sit Stand Keyboard Tray is assessed as a practical under-desk upgrade for anyone who alternates between sitting and standing. The single biggest reason to buy is its 13.4 in of vertical adjustment, which lets users match keyboard height to a raised monitor or standing desk converter for better posture. The review focuses on real use: build quality, range of motion, and day-to-day usability for full-size keyboards and a mouse.

Key Features

• 13.4 in vertical range: Allows the tray to lift 8.7 in above the desk for standing and drop 4.7 in below the surface for sitting, so users can align hands with screen height.
• Full motion platform: The tray swivels 90 degrees each way and tilts 15 degrees up and 13 degrees down to reduce wrist strain and support varied typing angles.
• Generous platform size: With 26.5 in width and 10 in depth, the surface accommodates a full-size keyboard and mouse side by side for comfortable spacing.
• Space-saving sliding design: The tray retracts under the desk when not in use, freeing desktop area and keeping the workspace tidy.
• Included comfort accessories: A soft mouse pad and wrist rest are provided to improve wrist comfort during longer sessions.
• Heavy-duty construction: Built from quality materials and designed for easy assembly, it aims to provide years of reliable use when installed on suitable desks.

Who It's For

The tray is best for home or office users who pair a sit-stand monitor solution with an under-desk keyboard platform and need a wide, adjustable surface for a full keyboard and mouse. It suits people who value ergonomic adjustability and a retractable tray that clears the desktop when not needed.

Those with unusually shallow desk clearance or desks thinner than 0.9 in should look elsewhere, and customers with an expectation of feather-light sliding action may be disappointed if they need very smooth, low-resistance movement in daily frequent adjustments.

Pros & Cons

Pros

• Wide height range supports both sitting and standing workflows effectively.
• Full motion tilt and swivel options let users fine-tune wrist angle and reach.
• Large 26.5 in platform fits a keyboard plus mouse and includes a wrist rest and mouse pad for comfort.
• Solid, heavy-duty build with straightforward assembly for most users.

Cons

• Track measures 6 in by 25 in and requires adequate under-desk space; it may be too tall for some conventional desks.
• Some users report the sliding mechanism feels heavy and does not glide as easily as expected.

Our Verdict

The Mount-It! Sit Stand Keyboard Tray is a practical, value-oriented choice for users who need a wide, height-adjustable under-desk platform to pair with a sit-stand monitor setup. Its robust adjustment range, full motion tilt and swivel, and included wrist support make it a solid ergonomic upgrade, though buyers should confirm under-desk clearance and expect a sturdy sliding action rather than a buttery glide.
