Who Should Buy the NB ERGONOMIC A3?

• Gamers who want their screen at the perfect angle without cable clutter
• Office users looking to free up desk space and reduce neck and eye strain
• Creators and editors who switch between landscape and portrait modes
• Users with 17–32 inch monitors who want a stable, long-lasting mounting solution
• Anyone upgrading from a stock monitor stand to a full-motion arm

NB ERGONOMIC A3 — Five-Axis Full Motion Adjustment

The NB ERGONOMIC A3 offers complete freedom of movement across five independent axes. In addition to the wide tilt range, the monitor head swivels left and right and rotates for portrait or landscape mode. Furthermore, both the upper and lower arms rotate a full 360° independently. As a result, you can position your monitor at virtually any angle — forward, back, high, low, or fully sideways — with smooth, consistent resistance throughout.

NB A3 — Patented Mechanical Constant-Force Spring

Unlike standard gas springs that can lose pressure over time, the NB ERGONOMIC A3 uses NB’s patented mechanical constant-force spring system. This spring structure maintains smooth, consistent resistance across 50,000+ fatigue-tested cycles. As a result, the arm feels exactly the same on day one as it does years later. Furthermore, the spring is housed inside the arm for a clean, minimal look while protecting the mechanism from dust and wear.

Smart-Balance Torsion Spring Pivot — No More Drooping

One of the standout features of the NB ERGONOMIC A3 is its intelligent torsion spring pivot system. This mechanism automatically matches the weight of your monitor — whether light or heavy — and maintains a constant 6–10N of holding force. As a result, the monitor stays exactly where you position it with no drooping or drifting over time. Furthermore, the pivot requires no manual tension adjustment — simply mount your monitor and the system calibrates itself.

NB True Quick-Release — Push to Lock, One Step Done

The NB ERGONOMIC A3 features NB’s proprietary True Quick-Release VESA plate system. Simply attach the VESA plate to your monitor, then push it onto the arm head — it clicks and locks instantly with no tools or screws required. In addition, a dust cap on the mounting head protects internal components and extends the arm’s service life. However, when you need to remove or swap monitors, the quick-release button allows single-handed detachment in seconds.

Built-In Hidden Cable Management

The NB ERGONOMIC A3 features a built-in hidden cable routing channel running the length of both arms. In addition, cable clips keep wires neatly secured from monitor to base. As a result, your desk stays clean, clutter-free, and organized — with no visible cables running loosely across your setup.

Dual Installation Modes — Clamp or Grommet

The NB ERGONOMIC A3 supports two installation methods to suit different desk types. Both options are included in the box. Furthermore, the 3-step installation process — mount the base, attach the arm, click the monitor into place — means setup is quick and straightforward without professional help.

• C-Clamp — clamps to the edge of any desk, no drilling required, fits desk thickness 20–80mm
• Grommet — inserts through an existing desk hole for a cleaner, more permanent installation

Frequently Asked Questions

Is the NB ERGONOMIC A3 compatible with my monitor?

The NB ERGONOMIC A3 is compatible with any monitor between 17–32 inches in size and 2–9KG in weight with standard VESA mounting holes (75×75mm or 100×100mm).

Does the NB ERGONOMIC A3 support portrait mode?

Yes. The VESA head rotates ±90°, allowing full portrait and landscape switching without removing the monitor from the arm.

What is the difference between a gas spring and the mechanical spring on the A3?

Gas springs use pressurized gas to hold the monitor — over time, gas can leak, causing the arm to lose holding strength. However, the NB ERGONOMIC A3 uses a patented mechanical constant-force spring that does not degrade over time. As a result, it maintains consistent resistance across 50,000+ tested cycles.

Will the monitor droop or drift after I position it?

No. The smart-balance torsion spring pivot automatically matches your monitor’s weight and maintains constant 6–10N holding force. As a result, the monitor stays exactly where you position it without any drooping or drifting.

Can I install the NB ERGONOMIC A3 without drilling?

Yes. The C-clamp installation method requires no drilling and fits desks between 20–80mm thick. However, if you prefer a cleaner look, the grommet method uses an existing desk hole. Both hardware sets are included in the box.
