Quick answer: The HUANUO FlowLift Single Monitor Arm is the best monitor arm for most people, with smooth gas-spring motion and a design tested for 20,000 movements. For two screens, the VIVO Dual Monitor Desk Mount is a proven favorite with more than sixty thousand ratings. If you use an ultrawide, the VIVO Single Ultrawide Monitor Arm holds screens up to 38 inches.
A monitor arm lifts your screen off the desk so you can set it at eye level, pull it closer, or push it away. That can reduce neck strain and frees up desk space.
I compared popular monitor arms on Amazon by screen size and weight limits, range of motion, mounting options, warranty, and owner feedback. I have not tested these arms myself; my picks are based on manufacturer specifications and verified owner reviews.

How to Choose a Monitor Arm
VESA compatibility
Check the back of your monitor for VESA mounting holes, usually 75x75mm or 100x100mm. Without them, you will need an adapter.
Screen size and weight
Make sure your monitor falls within both the size and weight range. Weight matters most, especially for gas-spring arms.
Gas spring vs. pole mount
Gas-spring arms move smoothly with one hand. Pole mounts are cheaper and very sturdy but need a tool or knob to change height.
Desk thickness and mounting
Check the clamp’s thickness range, and whether your desk has a grommet hole or a lip that could block the clamp.
Single or dual
Dual arms save space and keep two screens aligned. For an ultrawide or one large screen, a strong single arm is enough.
Finish your setup with one of my best standing desks and an ergonomic office chair.
Final Thoughts
The HUANUO FlowLift is my top pick for smooth movement and easy setup. Choose the VIVO Dual Monitor Desk Mount for two screens, the VIVO Ultrawide Arm for large ultrawide monitors, or the Amazon Basics Gas Spring Arm on a budget.
Frequently Asked Questions
Are monitor arms worth it?
Yes, for most people. A monitor arm makes it easy to set your screen at eye level and frees up desk space.
How high should a monitor be?
The top of the screen should be at or slightly below eye level, about an arm’s length away.
Can a monitor arm hold a curved monitor?
Yes, as long as the monitor has VESA holes and falls within the arm’s weight and size limits.
Will a monitor arm damage my desk?
Clamps can mark soft or thin desktops. Use the included padding, and consider a reinforcement plate for thin or glass desks.
