Who Should Buy the NB ERGONOMIC A5?

• Gamers running large 27–50 inch gaming or ultrawide monitors
• Users with curved or ultrawide screens that lighter standard arms cannot support
• Content creators and video editors who need a large display at the perfect angle
• Professionals looking for a clean, cable-managed heavy-duty desk mount
• Anyone upgrading from a stock monitor stand to a full-motion arm for large screens

NB A5 — Premium Mechanical Spring System

Unlike gas spring arms that can lose pressure over time, the NB ERGONOMIC A5 uses a heavy-duty mechanical spring mechanism. In addition, the spring is built to hold monitors from 2 to 18KG without drift or droop — covering everything from a slim 27-inch gaming monitor to a heavy 49-inch ultrawide. As a result, the arm holds its position precisely, with no sagging or floating regardless of monitor weight.

The spring tension is manually adjustable via a tension screw on the arm. Furthermore, tension should always be set with the monitor already mounted — do not adjust the screw without a monitor on the arm.

NB A5 — Full Motion Four-Axis Adjustment

The NB ERGONOMIC A5 provides a complete range of motion. In addition to mechanical spring height adjustment, the arm tilts, swivels at the head, and rotates at both the base and mid-joint. As a result, you can position any large or ultrawide screen at exactly the right height and angle for your posture — whether seated or standing.

Quick-Release Tool-Free VESA Head

The NB ERGONOMIC A5 features a quick-release VESA mounting head with a secure slide-and-click mechanism. In addition, the head allows one-person installation in under 5 minutes. Furthermore, removing or swapping monitors is equally simple — no tools required at any point during the process.

Built-In Cable Management

The NB ERGONOMIC A5 features integrated cable channels running through the full arm length. In addition, all monitor cables — power, display, and data — are routed neatly inside the arm structure. As a result, your desk stays clean, organized, and clutter-free without any additional cable management accessories.

Dual Installation — C-Clamp or Grommet

The NB ERGONOMIC A5 supports two installation methods, both included in the box. Furthermore, the installation process is straightforward with all required hardware provided.

• C-Clamp — clamps to the desk edge without drilling
• Grommet — inserts through an existing desk hole for a permanent, cleaner installation

Note: The A5 is not suitable for fragile desks (marble or glass), desks with irregular or beveled edges, or desks with narrow clamping surfaces.

Technical Specifications

Frequently Asked Questions

Is the NB ERGONOMIC A5 compatible with curved and ultrawide monitors?

Yes. The A5 is specifically designed for flat, ultrawide, and curved monitors from 27 to 50 inches, as long as the monitor has standard VESA mounting holes (75×75mm or 100×100mm) and weighs between 2 and 18KG.

What is the difference between the NB A5 and the NB A3?

The NB A3 is designed for smaller screens — 17 to 32 inches with a 2–9KG load limit. The A5 is the heavy-duty step up, supporting 27 to 50 inch monitors up to 18KG. In addition, the A5 uses a heavier mechanical spring and longer arm extension to handle the additional weight and width of large gaming and ultrawide monitors.

Does the NB ERGONOMIC A5 support portrait mode?

Yes. The VESA head rotates 360°, allowing full portrait mode switching without removing the monitor from the arm.

Why is a mechanical spring better for heavy monitors?

Gas springs use pressurized gas to support the monitor — however, over time gas can leak, causing the arm to gradually lose holding strength. In contrast, the A5’s mechanical spring does not degrade over time. As a result, it maintains consistent resistance and position-holding for heavy large-screen monitors across years of daily use.

Will my desk support the NB ERGONOMIC A5?

The A5 is a heavy-duty arm and requires a sturdy desk. Fragile desks (marble, glass), desks with beveled or irregular edges, and desks with narrow clamping surfaces are not suitable. Furthermore, always ensure your desk can support the combined weight of the arm and monitor before installation.
