Best Monitor Arm 2026 — Comparison & Reviews
In brief: A monitor arm is one of the best ergonomic investments for a desk. For £40-£130, you position your screen at exactly the right height, free up 20-30 cm of depth on your desk, and reduce the daily strain on your neck.
If your screen sits directly on the desk, it's probably too low — forcing your head forward and creating tension in your neck. A monitor arm solves this problem in 15 minutes of installation.
Why a monitor arm is essential
A screen resting on the desk is the number one cause of neck strain at work. The head weighs around 5 kg in a neutral position — but for every centimetre it tilts forward, the effective load on the cervical spine increases by 2-3 kg. A screen that's too low means a head tilted downwards, i.e. 8-12 kg of constant pressure on your neck for 8 hours.
A monitor arm solves this problem by letting you position the top of the screen exactly at eye level. It's the most cost-effective ergonomic investment after a good chair.
What a good monitor arm should do
Hold its position — Put the screen at the top, it stays at the top. Put it to the left, it stays to the left. Cheap arms use a friction mechanism that loosens over time.
Move with two fingers — The best arms (Ergotron with Constant Force) reposition with a light touch. No need to loosen and retighten screws.
Not wobble — A rigid arm avoids oscillation when typing. Critical for 27+ inch screens.
Free up space — By removing the screen's stand, you gain 20-30 cm of desk depth. That's significant in a small home office.
Our ranking
1. Ergotron LX — The absolute benchmark
Rating: 9.2/10 | Price: ~£110-£135
The Ergotron LX is the monitor arm most recommended by professionals for years. Its Constant Force system is patented: the resistance is calibrated to the screen's weight and holds position without friction or screws. The movement is silky, precise, and stays identical after 5 years of use.
Specs:
- Load: up to 11.3 kg (compatible with 34 inches)
- VESA: 75×75 and 100×100 mm
- Extension: 49 cm
- Rotation: 360°, tilt: +90°/-5°
- Integrated cable management
- Warranty: 10 years
Pros: Constant Force, 10-year warranty, compatible with large screens, premium finish. Cons: Price (~£120), slightly complex assembly on first setup.

2. Dell MSA20 — Best value for money
Rating: 7.8/10 | Price: ~£40-£47
The Dell MSA20 (~£45) is our recommendation for tight budgets. It uses an improved friction mechanism that holds up well for 6-12 months. For a 24-27 inch screen, it's sufficient.
Limitation: mechanical play appears after 1-2 years of heavy use — where the Ergotron LX stays perfect after 5 years.
Specs:
- Load: up to 5.8 kg (24-27 inches)
- VESA: 75×75 and 100×100 mm
- Extension: 46 cm
- Tilt: -5°/+70°
- Integrated cable management
Pros: Accessible price, good for standard screens, simple installation. Cons: Load limited to 5.8 kg, friction loosens over time.

3. Ergotron WorkFit-T — For sit-stand set-ups
Rating: 8.0/10 | Price: ~£130-£170
The Ergotron WorkFit-T is a sit-stand converter that sits on your existing desk. It's not a classic monitor arm but answers the same need: repositioning the screen at optimal height, here by letting you switch to standing.
The platform holds the screen and keyboard, and lifts to the desired height via a gas mechanism. Handy for remote workers who want to alternate postures without investing in a full electric desk.
Pros: Sit-stand converter, no drilling, quick transition. Cons: Bulky, doesn't free up desk space.

4. NB North Bayou — The budget alternative
Rating: 7.0/10 | Price: ~£25-£35
The NB North Bayou (~£25-£35) is the ultra-budget solution. Basic friction mechanism, but functional for a 22-27 inch screen with moderate use. At this price, compromises on smoothness and durability are inevitable.
Pros: Unbeatable price, quick installation. Cons: Basic friction, quick mechanical play, limited load.

Single or dual arm?
Single arm (Ergotron LX): enough for 1 screen, even 34 inch. More stable, simpler to adjust. Ideal for 90% of users.
Dual arm (Ergotron LX Dual): for 2 independent screens. Frees the desk completely but needs a solid desk clamp (thick desktop or robust clamp). The dual arm costs ~£210-£255.
Triple arm: reserved for professionals working on 3 screens. The Ergotron triple arm costs ~£300 and needs a very solid desk. Alternative: two separate arms (one single + one dual).
Our recommendation
If you have a single screen: get a single Ergotron LX arm. If you have two screens: the dual Ergotron LX Dual arm or two separate single arms (more flexible).

Quick installation: the 3 steps
- Check your screen's VESA compatibility (4 holes at the back)
- Choose the mounting mode: clamp (recommended, no drilling) or cable passthrough (for desks without a rim)
- Calibrate the tension for your screen: tighten/loosen the tension nut until the screen stays in position without effort
Estimated installation time
- Ergotron LX: 20-30 minutes (first time), 10 minutes (experienced)
- Dell MSA20: 10-15 minutes
- NB North Bayou: 10 minutes
Tools needed
Most monitor arms include the mounting tools (Allen key, screws, nuts). You only need a Phillips screwdriver to attach the VESA plate to the back of your screen.
By profile: which arm to choose
You have a single screen (24-34 inch) and want the best
→ Ergotron LX. The benchmark. Smooth movement, 10-year warranty, compatible up to 34 inches. A £120 investment that lasts a decade.
You have a tight budget and a standard screen
→ Dell MSA20. At £45, it's the best value for money for a 24-27 inch screen. Good enough for 6-12 months, then consider an upgrade.
You want to alternate sitting and standing
→ Ergotron WorkFit-T. Not a classic monitor arm, but a converter that lets you work standing up without changing your desk.
You have two screens
→ Ergotron LX Dual or two separate Ergotron LX arms. The dual arm is more compact, two separate arms offer more positioning flexibility.
The cost of ownership compared
| Model | Price | Estimated lifespan | Annual cost |
|---|---|---|---|
| NB North Bayou | ~£30 | 2-3 years | ~£12/yr |
| Dell MSA20 | ~£45 | 2-3 years | ~£17/yr |
| Ergotron LX | ~£120 | 10+ years | ~£12/yr |
The Ergotron LX and NB North Bayou have a similar annual cost (~£12/yr), but the experience of use is incomparable. The Ergotron's initial investment is fully justified by the smoothness of movement and the longevity.
The measured ergonomic impact
Installing a correctly adjusted monitor arm produces measurable effects:
- Reduction of neck tilt from 20-30° to less than 5°
- Reduction of neck strain felt within the first few days
- Gain in desk space of 20-30 cm of depth
- Instant adjustment of the screen position according to posture (sitting/standing)
For remote workers who spend 6h+ a day in front of a screen, the monitor arm is the second most cost-effective ergonomic investment after the chair.

What users say
Ergotron LX
Feedback is exceptional (4.8/5 across more than 3,000 reviews). Users praise the smoothness of the Constant Force movement and long-term reliability. Several users report perfect operation after 5+ years of daily use. Criticism focuses mainly on the price and the complexity of the initial assembly.
Dell MSA20
Good performance for the price (4.3/5 across more than 1,000 reviews). Users appreciate the simple installation and stability with 24-27 inch screens. Criticism focuses on the friction that loosens after 1-2 years and the max load limited to 5.8 kg.
NB North Bayou
Decent for the price (4.0/5 across more than 2,000 reviews). Users note the unbeatable value for money. Criticism focuses on the mechanical play that appears quickly and the difficulty holding heavy screens in position.
What to remember
The Ergotron LX is the monitor arm you won't need to replace for 10 years. Its Constant Force system is incomparable — once you've tried it, you can't go back to a friction arm. For small budgets, the Dell MSA20 does the job for a standard screen. And if your space doesn't allow a dedicated desk, the WorkFit-T converter is a viable alternative.
The most common mistake
Buying a monitor arm without checking your screen's VESA compatibility. Before ordering, flip your screen over and look for the 4 mounting holes (75×75 or 100×100 mm). If they're absent, you'll need a VESA adapter specific to your screen model — check availability before investing in the arm.
