6 Best Monitor Arm under $150 (November 2026)

One monitor on one arm is the simplest ergonomic upgrade a desk can get. The screen leaves the stock stand, floats at the height your eyes prefer, and slides in or out to match how you lean. Most people only notice how bad the old setup was after the arm goes on: a neck that tilts down at a laptop-height screen, a stand that eats a quarter of the desk, a panel that sits too close or too far. A good arm solves all three, and the single-screen version is cheaper and easier to place than a pair.

This guide is for anyone running a single display at home or at the office, from a compact 24-inch panel to a 34-inch ultrawide. It compares six arms using only their listing titles. Specs like gas-spring travel, clamp opening and arm reach are not always printed there, so confirm them on each product page in 2026 before you buy. Looking for two screens? That is a different job, with its own weight and spacing math, and it is covered in a separate guide.

How to Choose

Set the height by eye level, then pick the arm

The right height places the top third of the screen near eye level, with your head level and the monitor an arm’s length away. Stock stands often leave the screen too low. Before you buy, measure from your desk surface to your eye line while seated; that is how high the arm needs to lift the center of the screen. Arms with a tall pole raise a screen further than short ones, and a gas or spring mechanism lets you change it by hand without loosening anything.

Screen size and weight limit

Titles in this lineup list ranges of 13 to 32, 34 or 35 inches, and weight capacities from 19.8 up to 26.4 pounds. A typical 27-inch monitor weighs 10 to 15 pounds without its stand, while a 34-inch ultrawide can reach the high teens or beyond. Look up your monitor’s weight with the stand removed and keep a few pounds of margin. Also confirm the VESA mounting holes at the back of your panel; without them you need a separate adapter.

Spring or fixed tension

Fixed-tension arms hold position with friction at the joints and need a hex key adjustment when you swap monitors. Gas or mechanical spring models counterbalance the weight so a light push moves the screen. The spring type feels nicer when you change position often, which is the reason to pay a little more. If you set the arm once and leave it, a fixed design is fine.

Clamp, grommet and cable handling

Most arms clamp to the desk edge, and many accept a grommet mount through a hole. Check the supported desk thickness and avoid glass or hollow tops without reinforcement. Built-in cable guides tidy the lead from the monitor; they are a small feature that makes the desk look finished. Skip arms that demand special tools or odd hardware. Also check how the arm folds when you want to move it out of the way, because a mount that locks you into one position removes the main benefit of buying an arm. If your desk has a back lip or a modesty panel, measure the clearance before settling on a clamp.

The 6 Best Options

ErGear Single Monitor Arm

ErGear’s title leads with a fully adjustable mount for 13 to 34 inch screens and a fast install with a tool-free VESA connection. The pitch is speed: clamp the base, click the monitor onto the bracket and route the cable. For anyone who dislikes assembly, that matters more than a few extra pounds of capacity.

• Strength: tool-free VESA mounting saves time and frustration.
• Strength: it covers panels up to 34 inches, including many ultrawides.
• Trade-off: the title is cut off before the weight limit, so check that figure on the listing.

Skip it if you plan to hang a heavy monitor without confirming the capacity. It suits a typical office or home desk where a 24 to 27 inch display needs to float above a keyboard and be repositioned occasionally.

WALI Adjustable Single Monitor Arm

WALI states the highest capacity in this group, up to 26.4 pounds, along with 13 to 34 inch support and full motion with tilt, swivel and rotation. That makes it the most reassuring choice for a heavier monitor, particularly a larger gaming or ultrawide panel.

• Strength: the 26.4-pound limit gives the most headroom listed.
• Strength: rotation allows portrait use for coding or reading documents.
• Trade-off: the title ends mid-word on the clamp details, so confirm the clamp range.

Skip it if you want a spring-assisted arm that glides, because the title does not mention one. For a heavier screen that stays in place most of the day, it is a sound, plain choice, and the full-motion joints still let you bring the panel closer for detailed work. A video editor with a big, heavy display, or a trader who keeps one wide chart open all day, is the kind of buyer the capacity figure is aimed at.

5Rcom Single Monitor Arm

5Rcom describes a heavy-duty, fully adjustable mount for 13 to 35 inch computer screens that holds 22 pounds, with fast installation and cable management in black. The 35-inch ceiling is the largest in the group, so it is the arm to look at if you own a wide display.

• Strength: the 35-inch maximum is the largest listed here.
• Strength: cable management and a quick install are in the title.
• Trade-off: the 22-pound limit is lower than the WALI, so check your panel’s weight.

Skip it if your monitor sits near the weight limit, or if you want a known name with long support history. The brand is less familiar than some rivals, so read the warranty terms and return options on the listing page before you commit.

HUANUO FlowLift Single Monitor Mount

The FlowLift single arm is the lighter-duty option from a brand that sells many mounts. The title lists 13 to 32 inch support, a VESA mount with clamp and grommet base, and a fit range that starts at 4.4 pounds and ends near 19.8, which covers thin office panels and midsize gaming screens.

• Strength: both clamp and grommet bases are listed, giving flexibility on different desks.
• Strength: a published weight window helps you check compatibility.
• Trade-off: the 19.8-pound ceiling excludes heavier panels.

Skip it if your monitor is large and heavy, or if you want smooth spring motion. It makes sense for a lightweight 24 or 27 inch display on an ordinary desk, where a simple arm is all that is needed. Students and remote workers who move their setup between rooms will also like the clamp-or-grommet choice, because it adapts to whatever desk they inherit next.

HUANUO FlowLift Pro Monitor Arm

The Pro version adds the MechaSpring mechanism named in the title, which counterbalances the screen so you can move it with a light touch. It also lists tilt, swivel and rotation, and a tool-free VESA connection for 13 to 32 inch monitors.

• Strength: a spring mechanism makes height changes easy.
• Strength: tool-free VESA mounting speeds up setup.
• Trade-off: the title cuts off before the weight limit, and 32 inches is the ceiling.

Skip it if your screen is wider than 32 inches or if you never move the arm. For people who shift between sitting and standing, or who share a desk, the effortless adjustment is the main reason to prefer it. Confirm the listed capacity for your monitor. It also helps in a shared home office where a partner or a child uses the same desk at a different height, since a quick lift beats loosening a knob.

Basics Single Monitor Stand with Cable Management

The house-brand arm is the plain steel choice. The title lists a height-adjustable VESA desk arm with cable management, tilt and rotation, and steel construction. It targets buyers who prefer a familiar retailer label and a no-frills design over extra features.

• Strength: steel construction and built-in cable management are in the title.
• Strength: a straightforward arm with the basic adjustments most desks need.
• Trade-off: the title is cut off, so size and weight limits must be checked on the listing.

Skip it if you want a spring-assisted motion or published support for ultrawide panels. It is a pragmatic pick for an office where several identical desks need the same, durable arm, and for anyone who wants the simplest possible replacement for a wobbly stock stand. Read the full size and weight limits on the listing page before you order.

Which One Fits Your Situation

You have a 34-inch ultrawide

Look at the WALI first, with its 26.4-pound limit and 34-inch range, or the 5Rcom if you need a 35-inch ceiling. Weigh the panel before choosing, and remember that wide curved screens need extra reach to sit at a comfortable distance. A deeper desk or a longer arm helps; a shallow desk makes any big screen feel close.

You adjust your screen often

The HUANUO FlowLift Pro suits you, since the MechaSpring mechanism is built for easy movement.

You hate assembly

The ErGear and the Pro both list tool-free VESA mounting, which makes the install quicker.

You just need something simple and cheap

The HUANUO FlowLift single or the Basics stand cover the basics, as long as your monitor is within their listed limits. Either way, the arm only needs to hold one display, so there is no need to pay for features you will not use.

Common Mistakes

• Skipping the weight check and buying an arm that sags under the screen.
• Forgetting that a monitor needs VESA holes on the back.
• Clamping to a thin or glass desk without reinforcement.
• Setting the height by looks instead of eye level.
• Leaving the cable loose, so it pulls on the arm.

Frequently Asked Questions

Will an arm fit my monitor?

If the back has four screw holes in a square pattern, such as 75×75 or 100×100 millimeters, and the weight is under the limit, yes.

Is a spring arm worth it?

If you move the screen often, yes. If you set it once and leave it, a fixed arm is fine. The spring tension should be matched to your monitor, so a screen that is much lighter than the range can float upward unless you adjust it.

Can I mount a curved monitor?

Often, but check the listed screen sizes and weight. Curved and ultrawide panels can be heavy.

Does an arm save desk space?

Yes. The base is a small clamp, so the area under the screen is free for a keyboard or notebook, and you can slide the panel back to gain more room when you are not using it. Just keep the arm’s reach in mind so the screen can still come forward when you need it.
