A quality monitor arm does more than free up desk space. It positions your screen at the correct height and distance, reducing neck strain and improving posture throughout the workday. With options ranging from $120 to $509, choosing the right arm depends on your screen count, weight, and how often you reposition your display.
This guide covers the key factors to consider and recommends the best monitor arms available in Australia for different setups.

What to consider before buying
1. Screen count and size
Single arms suit most users with one monitor up to 32 inches. If you run dual screens, you need either a dedicated dual arm (like the CBS Flo Dual) or two individual arms. For ultrawide monitors over 34 inches, check the arm's weight capacity carefully as these displays are often heavier than standard panels.
2. Monitor weight
Every arm has a weight range. The CBS Flo supports 3 to 8kg, which covers most 24 to 32 inch monitors. The CBS Ollin extends to 9kg, and the Humanscale M8.1 handles up to 12.7kg. Always check your monitor's weight (including the stand removed) against the arm's rated capacity.
3. Desk mounting type
Most arms offer two mounting options: clamp (grips the desk edge) or bolt-through (permanent hole in the desk). Clamp mounts are easier to install and move. Bolt-through mounts are more stable and work better on thicker desks or when the arm carries heavy loads.
4. Movement type
Spring-assisted arms (like the CBS Flo) use a mechanical spring for smooth, tool-free height adjustment. Gas spring arms (like the Float range) use a pneumatic cylinder. Both work well, but mechanical springs tend to last longer and feel smoother over time.
5. Cable management
Look for arms with integrated cable channels or clips. The CBS Flo and Ollin both route cables through the arm itself, keeping your desk clean. Budget arms may only offer external clips.
Detailed product breakdown
CBS Flo Single ($259)
The benchmark for single monitor arms. The Flo uses a patented spring mechanism that allows effortless repositioning with one finger. No tools required for height, tilt, or rotation adjustments. Supports VESA 75/100 mounts and monitors from 3 to 8kg. Available in black, white, and silver. View the CBS Flo Single.
CBS Ollin ($314)
Designed for heavier monitors and deeper desks. The Ollin extends further than the Flo (up to 580mm reach) and supports screens up to 9kg. Its slimmer profile makes it less visually dominant on the desk. Ideal for users with 32 inch or larger displays. View the CBS Ollin.
CBS Flo Dual ($499)
Two independent Flo arms on a single post. Each arm moves independently, so you can position screens at different heights and angles. Supports two monitors up to 8kg each. The dual post design keeps the desk footprint minimal. View the CBS Flo Dual.
Float Single ($120)
A gas spring arm that delivers solid performance at an accessible price. Full height, tilt, swivel, and rotation adjustment. Supports monitors from 2 to 6.5kg. Integrated cable management. A strong choice for home offices or budget-conscious setups. View the Float Single.

Frequently asked questions
Do I need a monitor arm if I have a height-adjustable desk?
Yes. A sit-stand desk adjusts your overall working height, but a monitor arm lets you fine-tune screen position independently. This is especially important when switching between sitting and standing, as your optimal eye-to-screen distance changes.
Will a monitor arm fit my desk?
Most arms clamp onto desks 10 to 60mm thick. If your desk has a thick back rail or cable tray, measure the available clamping area first. Bolt-through mounting works on any thickness but requires drilling a hole.
Can I use a monitor arm with a laptop?
Yes. The CBS Flo with Laptop Mount holds a laptop on a tray using the same spring-assisted arm mechanism. This raises your laptop screen to eye level and frees up desk space.
How long do monitor arms last?
Quality arms like the CBS Flo and Ollin are rated for 10+ years of daily use. The spring mechanisms are tested to over 50,000 cycles. Budget gas spring arms typically last 5 to 7 years before the gas cylinder loses pressure.
