For years, I suffered from persistent wrist pain and discomfort stemming from my poor desk setup. The thought of investing in a solution that truly alleviated this problem seemed daunting until I discovered the VIVO Adjustable Computer Keyboard & Mouse Platform Tray Ergonomic Under Table Desk Mount Drawer Underdesk Shelf (MOUNT-KB03B). This review, based on my extensive use, shares my experience with this under-desk keyboard tray.
Many people experience discomfort from prolonged computer use, and under-desk keyboard trays offer a fantastic solution by promoting better ergonomics. They help alleviate wrist strain, neck pain, and backaches by allowing you to position your keyboard and mouse at a comfortable height and angle. However, the ideal buyer is someone with a standard desk (at least 5/8″ thick) with sufficient clearance underneath. Those with height-adjustable desks will need an additional spacer bracket (sold separately). Individuals using extremely large keyboards or needing substantial workspace might find a larger tray more suitable. Before purchasing any under-desk tray, consider your desk’s dimensions, the size of your keyboard and mouse, and your personal ergonomic preferences. Also, think about the weight capacity of your desk—ensure it can handle the added weight of the VIVO MOUNT-KB03B (approximately 10 pounds).
- Ergonomic Keyboard and Mouse Tray: Installs underneath a standard desk for comfortable typing angles --Patent Pending--
- Compatibility: If installing to a height adjustable desk, you will need a spacer bracket for the track to fit over the frame crossbar. Search for adapter MOUNT-SPACER01 (not included) for this purpose
- Deluxe Universal 25" x 10" Tray: Fits most keyboards and mice. The keyboard slides forward and back on a 14.25" long and 6.25" wide track (will need 14.25" between the desktop edge and crossbar)....

A Deep Dive into the VIVO MOUNT-KB03B’s Features and Benefits
Ergonomic Design and Adjustability
The VIVO MOUNT-KB03B‘s primary benefit lies in its adjustability. The ability to fine-tune the height and tilt of the keyboard and mouse is crucial for maintaining proper posture and reducing strain. I’ve found this particularly helpful as I can easily adjust the tray to accommodate different seating positions and tasks. The 5-inch height adjustment range and full side-to-side rotation allow for personalized comfort. The rubber padding adds a welcome layer of softness for my wrists and reduces the harshness of the metal frame.
Installation and Assembly
Despite some online concerns, I found the installation relatively straightforward. The instructions were clear, and all the necessary hardware was included. The pre-drilled holes aligned perfectly with my desk, and the whole process took less than 20 minutes. However, I strongly advise pre-drilling pilot holes before screwing into your desk; this prevents the wood from splitting. The included template is also helpful in determining the ideal placement and alignment.
Build Quality and Durability
While the VIVO MOUNT-KB03B feels sturdy enough for daily use, it’s not without its shortcomings. The sliding mechanism, composed of metal slides and plastic sliders, lacks the smooth glide of higher-end models with ball bearings. This results in a somewhat rough, scratchy movement when extending or retracting the tray. Also, I noticed a slight wobble, which is more pronounced when the tray is fully extended. The two-piece construction of the tray is noticeable, with a slight seam visible. The wood finish also lacks the richness shown in product photos; it appears more yellowish than the advertised brown. Despite these flaws, the tray has held up remarkably well over the years.
Size and Compatibility
The 25″ x 10″ tray is generously sized and comfortably accommodates my full-sized keyboard and mouse with plenty of room to spare. However, some users with larger keyboards or those who prefer a more expansive mouse area might find it a bit cramped. The compatibility is generally excellent, fitting most standard keyboards and mice without issue.
The Rubber Wrist Rest
The included rubber wrist rest is a welcome addition, offering good support and cushioning. However, the adhesive backing isn’t always reliable, and I’ve experienced instances where parts of the foam pad separated from the adhesive. A more durable adhesive would have improved this aspect significantly.
User Feedback: A Summary of Online Experiences
My own positive experience with the VIVO MOUNT-KB03B is corroborated by numerous positive online reviews praising its adjustability, ease of installation, and value for money. However, several reviewers echo my concerns about the sliding mechanism’s roughness and the slight wobble. Many have successfully mitigated these issues with lubrication or strategic installation placement.
Conclusion: Should You Buy the VIVO MOUNT-KB03B?
The VIVO MOUNT-KB03B effectively solves the problem of poor desk ergonomics, improving posture and reducing wrist strain. Its adjustable height, tilt, and large tray size are significant advantages. While the sliding mechanism isn’t flawlessly smooth and some minor wobble exists, the benefits outweigh these drawbacks for many users. For those seeking an affordable and functional under-desk keyboard tray, the VIVO MOUNT-KB03B is a worthwhile investment. To see if this product is right for you, click here to check it out .ca!
