A monitor arm does two things a stack of books cannot: it puts the top of your screen at eye height, and it gives you back the desk space underneath. Both matter more than people expect. Most neck complaints from desk work come down to looking slightly downwards for years.
Check compatibility first
Three numbers decide whether an arm will work for you: your monitor's weight, its VESA pattern (usually 75 × 75 mm or 100 × 100 mm), and your desk's thickness at the clamp point. An arm rated below your monitor's weight will drift downwards no matter how you tension it, and one rated above it will push the screen upwards. Use the weight on the manufacturer's spec sheet, not the shipping weight on the box, which includes the stand. Our four-step compatibility checklist walks through this.
Single, dual or laptop
Single arms suit one large screen, which is now the more common setup. Dual arms suit two matched monitors, and it is worth measuring your available desk width before committing, because two 27-inch screens side by side need more span than most people assume. If you dock a laptop alongside a monitor, a dedicated laptop mount keeps both at a sensible height.
What we stock
The CBS Flo uses a dual-rate spring that holds position across its whole range without retensioning, and takes screens from 2 to 7 kg up to 34″. It won a Good Design Award in 2025 and carries a 12-year warranty. For screens over 7 kg, or a 49″ ultrawide, the CBS Flo X is rated 3 to 18 kg — we order that one in, so call us on 02 9640 0642. Humanscale's M/Flex system is the one to look at for multi-screen or shared-desk environments, and Humanscale arms carry a 15-year warranty. Thinking Works covers the middle of the range. All of them carry long warranties, which matters for a product with moving parts you will adjust daily.
Alongside those we stock Float, our own house brand, made exclusively for Chair Dinkum. The Float Single ($120) and Float Dual ($160) use a mechanical spring mechanism and are rated 2 to 11 kg per screen, or 2 to 10 kg for curved monitors. The Single takes screens from 17 to 40″, the Dual from 17 to 35″ per screen, both with VESA 75 × 75 and 100 × 100 on a quick-release plate, tilt +75° / −45°, swivel ±90°, rotation ±180° and 469 mm of extension. The whole mount installs from above the desk surface, which is worth real money on a project: nobody has to get underneath a workstation, so installation is far quicker per desk and screens can be hung on desks that are already occupied. Both a desk clamp and a grommet mount are in every box, for tops 10 to 50 mm thick, along with integrated cable management. Powder-coated aluminium, steel and plastic, in Black and White, with a 3-year Chair Dinkum warranty — in addition to your rights under the Australian Consumer Law, which cannot be excluded. Float is the volume answer for a general workstation floor, the desks where every position needs an arm. For executive and client-facing desks, and for any desk where the arm will be handled dozens of times a day for a decade, specify CBS or Humanscale instead: the 12-year and 15-year warranties, and the build behind them, are what you are paying for there. If you are pricing a whole floor, see commercial office chairs Australia. (Float and the CBS Flo are different products despite the similar names — the Flo is a CBS arm rated 2 to 7 kg to 34″ with a 12-year warranty.)
