If you’ve ever felt cramped at your desk, with your keyboard taking up all the room, you’re not alone. Most people don’t realize how much strain a poorly placed keyboard can cause until the wrist pain or shoulder tension hits.
That’s where the Fellowes underdesk keyboard drawer comes in. It’s simple, sturdy, and designed to give your arms and wrists the break they deserve—while also freeing up your workspace.
In this guide, I’ll walk you through everything you need to know. From specs and setup to real user stories and expert comparisons, you’ll see exactly why this drawer might be your next best home office upgrade.
What Is the Fellowes Underdesk Keyboard Drawer?
The Fellowes underdesk keyboard drawer is a compact, slide-out tray that mounts under your desk. It’s designed to hold your keyboard and mouse in a lower position, giving you more space on top of your desk. This tray helps you sit in a better posture, which can ease wrist and shoulder pain. It’s great for small desks, remote workers, and anyone who wants a cleaner, more comfortable setup.
Core Features and Build Quality
The model most users choose is the Fellowes 9140303. It’s made from high-impact plastic that’s strong but lightweight. The surface is wide enough to hold both a standard keyboard and a mouse. It slides in and out smoothly using steel ball-bearing glide tracks.
This tray can be mounted in three height positions, so you can adjust it to fit your seating style. It also comes with a built-in mouse platform that can slide to either side—perfect if you’re left-handed or just want more flexibility.
The platform’s edges are curved to prevent sharp contact with your wrists, which is great for long workdays. It’s easy to clean, doesn’t attract dust, and stays stable once installed.
Why Choose a Keyboard Drawer?
Many people don’t realize how much a keyboard tray can change their work experience. Without one, your arms are often raised too high, which puts stress on your shoulders and neck. Over time, that can lead to pain or even long-term issues like repetitive strain injuries (RSI).
A good underdesk drawer helps you align your arms and wrists properly. It puts your keyboard and mouse at a natural angle, which experts say is one of the most effective ways to reduce discomfort while working at a computer. According to OSHA, proper keyboard height is a key part of ergonomic desk setup.
A tray also frees up space on top of your desk. That means more room for your notebook, coffee, or second screen—without feeling crowded. For people with small desks or multi-monitor setups, this is a simple way to make the most of your space.
Fellowes 9140303 Specs, Dimensions & Compatibility
Among the fellowes keyboard trays, Fellowes 9140303 is really exceptional. This is a admireable fellowes keyboard drawer we must say. Let’s look at how the Fellowes 9140303 compares to two other popular trays. Here’s a quick breakdown of the most important specs:
| Feature | Fellowes 9140303 | 3M AKT60LE | Mount-It! MI-7134 |
|---|---|---|---|
| Platform Width | 20.0 in | 17.0 in | 26.7 in |
| Material | High-impact plastic | Wood & steel | Plastic & metal |
| Max Load | Standard keyboard + mouse | Up to 15 lbs | Up to 10 lbs |
| Adjustable Height | 3 levels | Yes (tilt & height) | No |
| Mouse Tray | Built-in, left or right | Separate, adjustable | Fixed side extension |
This tray works best for people who want something simple, solid, and affordable. It’s wide enough for most users, though it may not suit oversized ergonomic keyboards.
Desk Fit & Installation Requirements
To install the 9140303, your desk must have a flat underside with enough space to mount the brackets. A desk width of at least 30 inches is recommended. The unit comes with all the screws and hardware you’ll need.
This tray works best with wooden desks or particleboard. It’s not ideal for glass desks or desks with metal frames that can’t be drilled. If your desk has a center drawer or support beam, you’ll need to measure first to be sure the tray will fit.
Make sure the depth of your desk allows for a tray that’s about 12 inches deep when fully extended. If your desk is shallower than that, the tray might stick out too far or not retract fully.
Laptop vs Desktop Use Cases
If you’re using a laptop with an external keyboard and mouse, this tray gives you a dedicated space to work. You can elevate your laptop on a stand and use the tray for typing. That’s a great ergonomic setup.
For desktop users, the tray lets you lower your keyboard below desk level, which helps create a neutral arm angle. That’s one of the best ways to avoid wrist or shoulder pain, according to the Mayo Clinic.
However, if your desktop tower sits directly beneath your desk, make sure it won’t block the tray. Also, if you’re constantly switching workspaces or sharing your desk with others, a stationary tray might not be ideal.
How to Install a Fellowes Keyboard Tray (Step-by-Step)
Tools You’ll Need
Before you start, gather a few basic tools: a Phillips-head screwdriver, a measuring tape, and optionally, a power drill if you want faster screw installation. The Fellowes 9140303 kit includes all necessary screws and mounting brackets. You can also download the official Fellowes installation manual for detailed guidance.
Step-by-Step Mounting Guide
Installing the tray is straightforward if you follow these steps carefully:
- Measure your desk’s underside: Find a flat area about 28-30 inches wide with enough clearance to slide the tray in and out freely.
- Mark mounting holes: Hold the mounting brackets where you want the tray. Mark screw locations with a pencil.
- Pre-drill pilot holes (optional): To avoid splitting wood, drill small pilot holes at the marked spots.
- Attach brackets: Use screws to secure the brackets firmly under your desk.
- Slide the tray into brackets: Align the tray with the bracket rails and gently slide it in. It should glide smoothly on steel ball bearings.
- Test sliding motion: Pull the tray out and push it back in a few times to check stability. Adjust screws if needed.
This process typically takes 15 to 20 minutes. For best results, ensure your desk is sturdy and can support the weight of the tray plus your keyboard and mouse.
Troubleshooting Tips
If the tray doesn’t slide smoothly:
- Check for obstructions under the desk.
- Tighten or loosen screws to reduce friction.
- Make sure the ball-bearing rails are aligned properly.
If screw holes don’t line up:
- Double-check your measurements.
- Adjust bracket position slightly.
- Use a drill to widen holes carefully if needed.

Fellowes vs Other Keyboard Tray Brands
Fellowes vs 3M Keyboard Trays
When comparing Fellowes to 3M keyboard trays, the main differences are in size, adjustability, and price. 3M trays usually offer more tilt and height options, which can be useful for precise ergonomic setups. However, they often cost more and sometimes require more complex installation.

Ergonomic Benefits of Using an Underdesk Keyboard Drawer
Back, Neck, and Wrist Health
Using an underdesk keyboard drawer helps position your arms and wrists correctly. When your keyboard is too high or too low, it strains your shoulders, neck, and wrists. The Mayo Clinic recommends that keyboards be positioned so your elbows are at about a 90-degree angle. This reduces muscle fatigue and lowers the risk of repetitive strain injuries (RSI).
Desk Space Optimization
A keyboard drawer frees up your desktop surface, giving you more room for other work essentials like documents, notebooks, or a second monitor. This extra space can reduce clutter, which studies by Harvard Business Review show leads to improved focus and productivity.
Better Productivity with Less Clutter
A clean, organized desk signals your brain that it’s time to focus. Reducing visible clutter helps decrease stress and increase mental clarity. Keyboard drawers contribute to this by hiding the keyboard when not in use and keeping your workspace neat. This simple change can lead to better concentration and longer periods of productive work.
Common Questions About Fellowes Keyboard Drawers (FAQ)
Will this tray fit a standing desk?
Most Fellowes underdesk keyboard trays, including the 9140303, are designed for fixed desks. However, they can fit some standing desks if the underside has enough clearance and a flat mounting surface. If your standing desk is adjustable in height, make sure the tray doesn’t hit the frame or obstruct leg movement. Always check desk dimensions before buying.
Can you install it without drilling?
The Fellowes 9140303 requires drilling to securely attach the mounting brackets under the desk. This provides better stability and smoother sliding action. If you prefer a no-drill option, look for clamp-style trays from brands like VIVO or Mount-It!, but these might be less stable over time.
What’s the weight capacity?
The tray supports a standard keyboard and mouse setup, typically up to about 10-15 pounds. It’s not meant for heavy equipment or multiple devices. Overloading the tray can cause damage or affect sliding performance.
Does it come with a warranty?
Fellowes offers a limited warranty on their keyboard trays. Generally, this covers manufacturing defects for one year. Check your specific purchase details or the Fellowes warranty page for exact terms and coverage.
Is it compatible with L-shaped desks?
The tray can work with L-shaped desks if installed on a flat section under the main desk surface. However, the installation might be trickier due to limited space or desk shape. Measuring carefully and ensuring enough clearance is essential for a good fit.
Where to Buy + Final Verdict
Should You Buy the Fellowes 9140303? If you want a simple, reliable way to improve your desk ergonomics and reclaim cluttered workspace, the Fellowes 9140303 underdesk keyboard drawer is an excellent choice. It offers smooth sliding rails, adjustable height, and a built-in mouse platform at a very affordable price. Installation is straightforward but requires basic tools and drilling.
