Monitor arms transform workspace ergonomics. They enable precise screen positioning that fixed stands cannot achieve, freeing desk surface while allowing easy adjustment. For anyone serious about their home office, a monitor arm is a fundamental upgrade.
This guide identifies the best monitor arms available in the UK, from budget options to premium solutions.
Why Monitor Arms Matter
Ergonomic Benefits
Fixed monitor stands rarely achieve optimal positioning. Either the screen is too low (forcing neck flexion) or fixed at a height that suits one position only.
Monitor arms solve this:
- Height adjustment - Position the screen so the top edge aligns with your eye level
- Depth adjustment - Move the screen closer or further for optimal viewing distance
- Tilt adjustment - Angle the screen to reduce glare and optimise viewing angle
- Easy repositioning - Adjust instantly when switching between sitting and standing
The ergonomic impact is significant. Proper screen positioning reduces neck strain, eye fatigue, and the postural problems that accumulate over years of desk work.
Space Reclamation
Monitor stands occupy valuable desk surface. Monitor arms lift screens above the desk, reclaiming that space for:
- Keyboard and mouse positioning
- Documents and notebooks
- Desk accessories
- Simply cleaner aesthetics
The visual impact is substantial. Desks with arm-mounted monitors appear more organised and professional.
Flexibility
Arms enable easy repositioning that fixed stands cannot match:
- Task switching - Move screens closer for detailed work, further for general use
- Sitting/standing - Adjust height when transitioning positions
- Sharing screens - Swivel to show others your work
- Cleaning - Move screens aside to access desk surface
Understanding VESA Standards
Most monitor arms use VESA mounting standards - patterns of bolt holes on monitor backs:
- 75x75mm - Smaller/older monitors
- 100x100mm - Standard for most modern monitors
- 200x100mm - Larger monitors (32”+)
- 200x200mm - Large curved or ultrawide displays
Check your monitor’s specifications for VESA compatibility before purchasing arms. Some monitors (particularly curved or ultrawide models) require specific arm ratings.
Best Premium Monitor Arms
Ergotron LX
Price: GBP135-165 (single) | Weight capacity: 3.2-11.3kg | Warranty: 10 years
The LX is the industry standard for quality monitor arms. Ergotron essentially invented the category, and the LX represents decades of refinement.
The arm moves fluidly in all directions - height, depth, tilt, rotation. Cable management is integrated into the arm design. Build quality is exceptional, with metal construction throughout.
The tension adjustment system allows precise calibration for your monitor’s weight. Once set, the arm holds position indefinitely without drift.
Why we recommend: Best-in-class build quality, movement fluidity, and durability. The benchmark by which other arms are judged.
Humanscale M8.1
Price: GBP269 | Weight capacity: 3.6-12.7kg | Warranty: 15 years
Humanscale brings premium ergonomic design to monitor arms. The M8.1 uses their signature weight-compensating mechanism that automatically adjusts to your monitor - no manual tension adjustment needed.
The design is minimalist and attractive, with clean lines that suit premium office aesthetics. Cable management is elegant and hidden. Movement is smooth and precise.
Why we recommend: Best automatic adjustment. Premium aesthetics for design-conscious users.
Herman Miller Ollin
Price: GBP289 | Weight capacity: 4.1-10.4kg | Warranty: 12 years
Herman Miller’s monitor arm matches their furniture design philosophy - functional excellence in attractive form. The Ollin uses a gravity-based adjustment system that requires no manual calibration.
Movement is exceptionally smooth. The arm “floats” to any position and stays there. Cable management is integrated and nearly invisible.
Why we recommend: Best from Herman Miller. Matches their furniture range for cohesive setups.
Best Mid-Range Monitor Arms
Amazon Basics Premium Monitor Arm
Price: GBP109 | Weight capacity: 2.3-11.3kg | Warranty: 1 year
Amazon Basics contracted with Ergotron for this arm - it’s essentially an LX at lower pricing. Build quality mirrors the LX, with fluid movement and solid construction.
The main difference is warranty (1 year vs 10) and colour options (fewer choices). For users confident in the product or willing to replace if issues arise, the value is exceptional.
Why we recommend: Best value premium arm. LX-equivalent quality at significant savings.
Arctic X1
Price: GBP45-65 | Weight capacity: up to 10kg | Warranty: 6 years
Arctic provides remarkable value in monitor arms. The X1 uses quality materials with smooth gas-spring adjustment. Build quality exceeds expectations for the price.
Cable management is included. Movement is not quite LX-smooth but entirely adequate for daily repositioning. The 6-year warranty provides unusual confidence at this price point.
Why we recommend: Best value overall. Quality approaching premium arms at budget pricing.
Duronic DM351X3
Price: GBP45-55 | Weight capacity: 8kg | Warranty: 5 years
Duronic offers straightforward value. The DM351X3 provides essential functionality - height, tilt, rotation - at accessible pricing. Build quality is adequate for the price.
Movement is acceptable if not premium-smooth. Cable management is basic but functional. For users wanting arm benefits without premium investment, Duronic delivers.
Why we recommend: Solid budget option. Essential features at minimal investment.
Best Dual Monitor Arms
Ergotron LX Dual
Price: GBP275-325 | Weight capacity: 3.2-11.3kg per arm | Warranty: 10 years
The dual LX extends Ergotron’s quality to two-monitor setups. Each arm operates independently while sharing a common pole mount. This allows asymmetric positioning - primary monitor centred, secondary angled.
Build quality matches the single arm. Movement is equally smooth. Cable management handles both screens cleanly.
Why we recommend: Best premium dual arm. LX quality for two monitors.
Amazon Basics Dual Monitor Arm
Price: GBP165-189 | Weight capacity: 2.3-11.3kg per arm | Warranty: 1 year
The same Ergotron-sourced quality in dual configuration. Each arm provides full independent movement. The value proposition is strong for dual setups.
Why we recommend: Best value dual arm. Premium quality at mid-range pricing.
HUANUO Dual Monitor Arm
Price: GBP35-50 | Weight capacity: 8kg per arm | Warranty: 3 years
HUANUO provides entry-level dual arms at remarkable prices. Build quality is basic but functional. Movement is adequate for occasional repositioning.
For users uncertain about dual-arm benefits or on strict budgets, HUANUO allows experimentation without significant investment.
Why we recommend: Budget dual option. Essential features at entry pricing.
Specialist Options
Ultrawide Monitor Arms
Ultrawide monitors (34”+) require arms rated for their weight and dimensions. Standard arms may not provide adequate support.
Recommended: Ergotron HX (up to 19.1kg, GBP285) handles the largest ultrawides including curved models.
Heavy Monitor Arms
Large 32”+ 4K monitors can exceed standard arm weight limits. Check specifications carefully.
Recommended: Ergotron HX supports monitors up to 19.1kg - adequate for virtually any monitor.
Standing Desk Compatible
For standing desks, choose arms that:
- Clamp securely to moving surfaces
- Provide adequate height range for sitting and standing
- Move smoothly for frequent repositioning
Most quality arms work fine; verify clamp compatibility with your desk edge.
Installation Guide
Clamp Mount
- Position arm base at desk edge
- Tighten clamp securely
- Ensure arm doesn’t interfere with drawers or legs
- Verify stability before attaching monitor
Grommet Mount
- Identify or drill grommet hole in desk
- Insert grommet base through hole
- Secure from underneath
- Note: requires hole of appropriate diameter
Monitor Attachment
- Remove monitor stand base
- Align VESA plate with monitor holes
- Secure with provided screws
- Don’t overtighten - snug is sufficient
Tension Adjustment
- Attach monitor to arm
- Adjust tension until monitor holds position without drifting
- Test movement in all directions
- Readjust if monitor sinks or rises when released
Common Questions
Will my desk support an arm?
Most desks work with clamp mounts. Verify:
- Desk edge thickness (typically 1-5cm, check arm specifications)
- Edge overhang allows clamp access
- Desk structure is solid (particleboard can compress over time)
Can I use laptop stands with arms?
Yes - VESA-compatible laptop trays attach to monitor arms, allowing laptops to be positioned alongside monitors.
Do I need cable management?
Integrated cable management keeps arms looking clean. Without it, cables hang visibly and can interfere with arm movement.
