Research-led UK workspace guide, October 2026. A good desk accessory should solve a measurable problem: a screen at the wrong height, a laptop that blocks desk space, cables that snag when the desk moves, or a surface that wears quickly. Choose accessories for your existing desk and devices, not simply by appearance. No first-hand performance tests or live retail prices are claimed here.
Four accessories worth considering
| Accessory | What it solves | Essential compatibility check | When to skip it |
|---|---|---|---|
| Monitor arm | Adjustable screen position and free desk space | Monitor VESA pattern, total weight including accessories, clamp/grommet fit, desktop strength | When the desktop is too thin, fragile or obstructed by a cable tray |
| Laptop stand | Raises a laptop screen and improves desk organisation | Laptop footprint, weight, ventilation, stability and external input devices | If you must type on the laptop keyboard and the raised position becomes uncomfortable |
| Under-desk cable tray | Keeps power and signal cables clear of feet and moving mechanisms | Desktop fixing method, cable bend radius, power strip dimensions, sit-stand travel | If installation would compromise the desk surface or block ventilation |
| Desk mat | Protects finish and provides a consistent mouse surface | Size, grip, edge stitching, surface finish and cleaning | If the mat traps moisture or interferes with the mouse sensor |
Before buying a monitor arm
Measure the display’s VESA mounting pattern, which may be 75 × 75 mm or 100 × 100 mm on many monitors, but not all. Compare the arm’s rated load with the actual monitor weight without its original stand, and check whether the arm’s minimum supported weight also matters for gas-spring designs. Confirm the desk clamp can fit around rear aprons, cable channels and sit-stand frames. For large ultrawides, check manufacturer-specific mounting requirements and the arm’s tilt capacity, not just a generic weight limit.
How to arrange a laptop and external monitor
If you use a laptop stand for long periods, an external keyboard and mouse can keep the input position comfortable while the screen is raised. A dock may simplify connections, but USB-C shape alone does not guarantee video output or charging. Check the laptop’s supported USB-C modes and power needs before buying a hub or dock. A closed-lid setup should follow the laptop manufacturer’s cooling guidance.
Managing cables safely
- Route power cables without crushing them against metal edges or the moving parts of a standing desk.
- Leave enough slack for the desk’s full height range and avoid pulling connectors taut.
- Do not coil power cords tightly around heat-generating adapters or bury adapters where they cannot dissipate heat.
- Use suitable fasteners for the desktop material; adhesive cable holders may fail under the weight of a loaded power strip.
- Keep liquids away from electrical connections and make sure sockets remain accessible.
A practical buying order
First: measure the desk, screen and laptop. Second: fix screen and keyboard positioning using the equipment you already own. Third: buy a stand or arm only when it passes the physical compatibility checks. Fourth: add cable management after the final equipment positions are known. Last: consider cosmetic accessories such as lighting and matching desk mats.
Five-minute desk compatibility check
- Measure the desk: note desktop thickness, usable depth and any rear crossbar. Photograph the underside if you intend to fit a monitor-arm clamp or cable tray.
- Check the monitor: record its exact model, VESA hole spacing and weight without the stand. Compare these figures with the arm manufacturer’s stated minimum and maximum load.
- Test your laptop position: raise the screen temporarily using a stable, safe support. If the built-in keyboard becomes uncomfortable to use, budget for an external keyboard and mouse rather than assuming a riser alone solves the problem.
- Move the desk through its range: if it is height adjustable, identify cables that become taut or catch on the frame before choosing a tray or clips.
- Build a shopping list: buy only the accessory that solves a measured problem, then check returns and mounting requirements before installation.
Example: A monitor can be VESA-compatible yet unsuitable for a particular arm because its weight falls below a gas-spring arm’s minimum rating or the desk cannot accept the clamp. The correct purchase depends on all three: screen, arm and desk.

Our accessory value test
We compared add-ons by whether they correct a problem that can be measured: a screen below eye level, a laptop occupying too much workspace, an uncomfortable pointing-device position or cables restricting a sit-stand desk. That separates a useful upgrade from a decorative one. A monitor arm may improve positioning but requires a suitable desk and display; a laptop riser often needs an external keyboard and mouse to be genuinely ergonomic.
Our practical purchase order is to fix the desk and screen position first, then input comfort and cable movement, and only then consider extras such as lighting or desk mats. We would not recommend buying a monitor arm solely because the display is described as VESA-compatible: the weight, clamp and movement envelope must also match.
Our assessment: spend on the accessory that removes a daily irritation rather than buying a matching set for appearance alone. We have evaluated published specifications and ergonomics guidance, not conducted long-term product wear tests.
