A steel, center-pole design for two monitors when cost matters more than frequent independent repositioning. The listing specifies 13–30 inch screens, up to 22 pounds per arm, VESA 75×75 or 100×100, and clamp or grommet installation.
Check before buying: Its arms adjust along a center pole. Confirm that this movement style works for your preferred monitor heights and depths.
Check current details on Amazon ↗Independent full-motion arms for 13–32 inch screens weighing 4.4–19.8 pounds each. The listing specifies VESA 75×75 or 100×100, a 15.75-inch maximum height, and a 17.32-inch maximum extension.
Check before buying: HUANUO recommends a wood desk 0.59–3.54 inches thick and says the underside must not have a crossbeam or panel that blocks installation.
Check current details on Amazon ↗A larger aluminum dual-arm model listed for 13–40 inch screens up to 26.4 pounds each. The listing specifies VESA 75×75 or 100×100, arms that rise to 21.1 inches and extend to 25.59 inches, plus two built-in USB ports.
Check before buying: Verify your monitor weight and desk structure. A higher capacity does not make every desktop suitable for a clamp mount.
Check current details on Amazon ↗Choose the VIVO when both screens fit its range and you expect to set the height once. Choose the FlowLift when you want independent arms and both screens fall inside its narrower weight limit. Consider the HNDS7 when either screen is larger or heavier, or when you need more reach. Reject any option that fails even one size, weight, VESA, desk-thickness, or underside-clearance check.
