None of the arms in this guide ship with a built-in laptop tray, and it is worth saying that plainly before you buy. What every arm here does offer is a standard VESA mounting head, which is what actually determines whether you can attach a separate VESA laptop tray adapter later and turn a single monitor arm into a combined monitor-and-laptop setup. That distinction, integrated tray versus VESA adapter approach, is the difference between a mount that already does the job and one that needs one more part.
Below are 8 VESA-compatible monitor arms we compared on weight rating, reach, and cable routing capacity, since a laptop tray adapter adds real weight and at least one extra thick charging cable to whatever the arm already has to support. A 27-inch monitor alone runs about 5kg, but add a 17-inch laptop at roughly 3kg and the arm needs real headroom in its rated capacity, not just enough to hold the monitor by itself.

Our Picks
Best Budget VESA-Compatible1 of 8
ErGear Single Monitor Arm on Amazon (opens in a new tab)
This is a standard single monitor arm, not an arm with a built-in laptop tray, so a separate VESA laptop tray adapter is required to add laptop support.
Best for
- Buyers adding a VESA laptop tray adapter on the tightest budget
Why we like it
8 lbs on a max VESA 100x100mm head, which covers the monitor and a light adapter tray combined but leaves little margin for a heavier 16-inch laptop.
Tool-free VESA installation and built-in cable management make it an easy first arm for a combined monitor-and-laptop setup on a budget. 8 lb rating as a ceiling, not a target, once you factor in the added tray hardware.
Tool-free VESA mounting for a quick tray-adapter swap.
Key dimensions & specs
- 13-34 inch monitor VESA compatibility
- Holds up to 19.8 lbs total
- Max VESA 100x100mm
- Tool-free installation
- Built-in cable management channel
Pros
- Lowest price in this list
- Tool-free VESA mounting for a quick tray-adapter swap
- Built-in cable channel helps route a laptop power cable
- Fits a wide 13-34 inch monitor range
Cons
- No built-in laptop tray, requires a separate VESA adapter purchase
- 19.8 lb rating leaves little headroom for a heavy laptop plus tray
- Basic single-arm design without gas spring tension adjustment
Best Value2 of 8
HUANUO FlowLift Single Monitor Mount on Amazon (opens in a new tab)
Adding a VESA laptop tray means the total load sits closer to that upper limit, so this suits lighter 13-14 inch laptops better than a heavier 16-inch model.
Best for
- Buyers pairing a light 13-14 inch laptop with a mid-size monitor
Why we like it
A clamp and grommet base give you flexibility for how you mount it to a desk that also needs to route a laptop charger alongside the monitor cable. It is a reasonable middle ground between the cheapest and premium arms here.
Key dimensions & specs
- 13-32 inch monitor compatibility
- Holds 4.4 to 19.8 lbs
- VESA mount with clamp and grommet base
- Full-motion adjustability
Pros
- Works with both clamp and grommet desk mounting
- Fits a broad 13-32 inch monitor range
- Full-motion tilt, swivel, and rotation
- Reasonable weight ceiling for a light laptop plus tray
Cons
- No built-in laptop tray, VESA adapter sold separately
- 4.4 lb minimum load can under-tension with very light monitors
- Not rated for a heavier 16-inch laptop plus a large monitor combined
Best Gas-Spring Feel3 of 8
HUANUO FlowLift Pro Monitor Arm on Amazon (opens in a new tab)
The FlowLift Pro uses HUANUO's MechaSpring mechanism for smoother, more even resistance when repositioning, which matters more once you add a laptop tray adapter and start adjusting both screens together.
Best for
- Buyers who want smoother repositioning once a laptop tray is attached
Why we like it
8 lbs, the same ceiling as the standard FlowLift.
Tool-free VESA installation and a choice of C-clamp or grommet base keep setup simple. This is still a monitor-only arm, so the laptop side of the setup depends entirely on adding a compatible VESA tray.
Tool-free VESA head for quick tray-adapter changes.
Key dimensions & specs
- 13-32 inch monitor compatibility
- MechaSpring mechanism for smoother adjustment
- Max load 19.8 lbs
- Tool-free VESA mount
- C-clamp or grommet base
Pros
- Smoother tension adjustment than a basic gas spring
- Tool-free VESA head for quick tray-adapter changes
- Full tilt, swivel, and rotation range
- Flexible clamp or grommet base mounting
Cons
- No integrated laptop tray, still needs a separate VESA adapter
- Same 19.8 lb ceiling as the cheaper FlowLift model
- Premium mechanism adds cost over the base ErGear pick
Best for Larger Monitors4 of 8
WALI Single Monitor Mount on Amazon (opens in a new tab)
4 lb total load, a higher ceiling than the FlowLift or ErGear picks at a similar price.
Best for
- Buyers wanting extra weight headroom for a heavier laptop plus tray
Why we like it
That extra headroom is useful once a VESA laptop tray adapter and a heavier laptop are added to the monitor's own weight.
VESA 75/100mm compatibility covers most laptop tray adapters on the market. It is still a monitor arm at its core, not a dedicated laptop mount, so confirm your tray adapter's own weight rating before loading a 16-inch laptop onto it.
Key dimensions & specs
- 13-34 inch monitor compatibility
- Regular screens up to 32 inches supported
- 26.4 lb total capacity
- VESA 75/100mm
Pros
- 26.4 lb capacity, higher than most budget arms in this list
- Wide 13-34 inch monitor compatibility
- Low price relative to its weight rating
- Standard VESA 75/100mm fits most tray adapters
Cons
- No built-in laptop tray, adapter purchased separately
- Basic clamp hardware, no C-clamp and grommet choice
- Cable management is minimal compared to pricier arms
Best Compact5 of 8
NB SmooVex Monitor Mount on Amazon (opens in a new tab)
The SmooVex fits monitors up to 32 inches on a standard VESA 75/100mm head, keeping the footprint compact for a smaller desk that still needs to fit a laptop tray adapter alongside the monitor arm.
Best for
- Buyers with a small desk who still want a monitor-plus-laptop arm setup
Why we like it
Its mechanical spring mount gives it steady resistance for repositioning.
As with the rest of this list, it is a monitor-only arm, so plan for a VESA laptop tray purchase to complete a combined setup. The compact base makes it a reasonable fit where desk space is the limiting factor.
Standard VESA 75/100mm fits most tray adapters.
Key dimensions & specs
- Fits monitors up to 32 inches
- VESA 75/100mm mount
- Mechanical spring mount
- Compact base footprint
Pros
- Compact footprint suits small desks
- Standard VESA 75/100mm fits most tray adapters
- Steady mechanical spring resistance
- Mid-range price for its feature set
Cons
- No integrated laptop tray
- Weight rating not as high as the WALI or TitanLift picks
- Fewer bundled accessories than the Ergotron picks
Best for Heavy Combined Load6 of 8
HUANUO TitanLift Heavy Duty Monitor Arm on Amazon (opens in a new tab)
The TitanLift is rated for screens up to 49 inches and up to 44 lbs, roughly double the capacity of the budget arms in this list.
Best for
- Buyers combining a large monitor with a heavier 16-inch laptop and tray
Why we like it
That headroom is exactly what a combined monitor-plus-laptop-tray setup needs, since an 8kg total load (a 27-inch monitor plus a 17-inch laptop) can push lighter arms past their comfortable range.
Aluminum construction and a dual C-clamp base add stability under that heavier combined weight. It is still built around a monitor VESA head rather than a laptop tray, so a compatible adapter is still part of the equation.
Key dimensions & specs
- Fits screens up to 49 inches
- Holds up to 44 lbs
- Aluminum construction
- Dual C-clamp base
- Max VESA 100x100mm
Pros
- 44 lb rating, the highest in this list
- Aluminum build adds stability under a heavier combined load
- Dual C-clamp base resists tipping under weight
- Room to add a laptop tray adapter without maxing out capacity
Cons
- Priced well above the budget picks in this list
- Larger arm footprint needs more desk clearance
- Still no integrated laptop tray, VESA adapter required
Best Premium7 of 8
Ergotron LX Monitor Arm on Amazon (opens in a new tab)
Ergotron's LX fits flat, curved, and ultrawide monitors up to 34 inches at 7 to 25 lbs, on a VESA 75x75mm or 100x100mm head that accepts most third-party laptop tray adapters.
Best for
- Buyers who want a premium arm foundation before adding a laptop tray
Why we like it
Its gas spring is built for years of daily repositioning rather than the lighter-duty springs on budget arms.
This is a monitor arm, not a laptop arm, and the 25 lb ceiling means a heavier laptop plus adapter tray should be checked against your specific tray's own rated weight. The premium build quality is the main reason to pay this much over the budget picks here.
Wide monitor compatibility including curved and ultrawide.
Key dimensions & specs
- Fits flat, curved, and ultrawide monitors up to 34 inches
- 7 to 25 lb capacity
- VESA 75x75mm or 100x100mm
- Matte black finish
Pros
- Premium gas spring built for years of daily use
- Wide monitor compatibility including curved and ultrawide
- Dual VESA pattern support for more tray-adapter options
- Reputable brand with long-term reliability
Cons
- Significantly more expensive than the budget arms here
- 25 lb ceiling still requires checking laptop tray weight separately
- No built-in laptop tray, adapter sold separately
Best for Long-Term Reliability8 of 8
Ergotron Upgraded LX Pro Premium Monitor Arm on Amazon (opens in a new tab)
The upgraded LX Pro covers flat, curved, and ultrawide monitors up to 34 inches at 4 to 22 lbs, with the same dual VESA pattern support as the standard LX.
Best for
- Buyers who want the longest-term reliability before adding a laptop tray
Why we like it
Ergotron's warranty on this line is longer than what budget brands typically offer, though it covers manufacturing defects rather than the wear a gas spring naturally sees under years of adjustment.
As with every arm in this list, there is no built-in laptop tray, so a VESA adapter is still required to add laptop support. The white finish and refined joint design are the main upgrades over the standard LX.
Key dimensions & specs
- Fits flat, curved, and ultrawide monitors up to 34 inches
- 4 to 22 lb capacity
- VESA 75x75mm or 100x100mm
- White finish
Pros
- Longer warranty coverage than budget brands
- Refined joint design for smoother long-term adjustment
- Wide monitor compatibility including curved and ultrawide
- Dual VESA pattern support for tray-adapter flexibility
Cons
- Highest price in this list
- 22 lb ceiling is slightly lower than the standard LX
- Warranty does not cover normal gas spring wear, only defects
How We Chose These Monitor Arms for Laptop
Each pick was assessed across 5 criteria weighted for real-world use.
- VESA compatibility for a tray adapter
- Confirmed each arm's VESA pattern (75x75mm or 100x100mm) since that is what actually determines whether a separate laptop tray adapter can attach at all.
- Compared each arm's rated capacity against a realistic combined load, a monitor plus a laptop and tray adapter, rather than the monitor's weight alone.
- Reach and desk depth fit
- Checked reach and retraction range so the arm can actually position a monitor and laptop tray comfortably on a typical 60-80cm-deep desk.
- Evaluated whether the arm's cable channel can realistically handle a power adapter cable plus an HDMI or DisplayPort cable, the minimum a combined setup needs.
- Value for the intended use
- Weighed price against weight rating and build quality, since a heavier combined load justifies paying more for a sturdier arm like the TitanLift or Ergotron picks.
What to Look for in a Monitor Arm for Laptop
Key buying criteria so you get the right fit the first time.
Confirm your desk can actually grip the mounting base before comparing arms
A monitor arm's clamp or grommet base needs a solid desk edge to grip securely, and this is the real first question to answer before comparing gas spring tension or weight capacity, since a hollow honeycomb-core desktop, a glass top, or a desk under about an inch thick can rule out an entire category of arms regardless of how good the arm itself is.
This matters because discovering after purchase that your desk simply can't mount the arm you bought is a common and entirely avoidable problem.
Check your desk's actual edge thickness and construction (solid, hollow-core, or glass), and confirm the arm's clamp or grommet base is explicitly rated for that construction before ordering.
Check real per-arm weight capacity, not the bundled-stand weight printed on the monitor box
Monitor weight ratings printed on the box often reference the monitor's included stand, not the bare panel weight relevant to a monitor arm, and a monitor arm's real weight capacity needs to match your specific monitor's actual panel weight without its stand, information usually found in the monitor's separate spec sheet rather than the box itself.
This matters directly for a larger or ultrawide monitor, where the gap between stand-inclusive and bare-panel weight can be substantial enough to matter.
Check your monitor's bare panel weight (without its stand) in its official spec sheet, and compare that specifically against the arm's rated capacity, not a generalized weight class.
Verify VESA compatibility for both your monitor and the arm's mounting plate
VESA mounting patterns come in a few standard sizes (75x75mm and 100x100mm are most common), and a mismatch between your monitor's VESA pattern and the arm's mounting plate means the arm simply won't attach, some arms include an adapter for multiple patterns while others support only one.
This matters directly for a monitor with a non-standard or larger VESA pattern, particularly some ultrawide or curved monitors, where assuming universal compatibility can lead to an unusable purchase.
Check your monitor's specific VESA pattern in its spec sheet, and confirm the arm explicitly supports that pattern, either natively or with an included adapter, before ordering.
Understand gas spring tension and how it affects long-term reliability
A gas spring monitor arm relies on an internal pressurized cylinder to hold the monitor at any height with minimal effort, and tension needs to be roughly matched to your monitor's actual weight, a monitor lighter than the spring's calibrated range can drift upward on its own, while pressure calibrated too low for a heavier monitor won't hold position and will slowly droop.
This matters for long-term usability, not just initial setup, since gas springs can also lose tension gradually over years of use.
Check the arm's rated weight range against your monitor's actual weight, favoring a monitor that falls comfortably within the middle of that range rather than at either extreme.
Consider reach and range of motion against your actual desk depth and seating position
An arm's horizontal reach and vertical range of motion determine how far the monitor can extend from the mounting point and how much height adjustment is available, and these dimensions matter differently depending on your desk depth and how far back you sit, a shallow desk needs less reach than a deep one, and a standing desk that changes height throughout the day needs a wider vertical range to stay at eye level.
This matters more for anyone switching between sitting and standing regularly, less for a fixed single seated position.
Check the arm's listed reach and height range against your actual desk depth and how much your seated or standing eye level varies throughout the day.
How to Choose a Monitor Arm for Laptop
By Rating Confidence: Highest Rated vs Most Reviewed
| Ergotron Upgraded LX Pro Premium Monitor Arm |
Dual-Monitor Arm vs Single-Monitor Arm
- Mounts two monitors from one clamp point, worth checking the combined weight rating. In this comparison: HUANUO TitanLift Heavy Duty Monitor Arm, Ergotron LX Monitor Arm, Ergotron Upgraded LX Pro Premium Monitor Arm.
- Simpler and usually cheaper per monitor, fine for a one-screen setup. In this comparison: ErGear Single Monitor Arm, HUANUO FlowLift Single Monitor Mount, HUANUO FlowLift Pro Monitor Arm, WALI Single Monitor Mount, NB SmooVex Monitor Mount.
Default to single arms unless you're mounting two monitors from the same desk clamp point.
| Standard desk edge, clamp mount | HUANUO TitanLift Heavy Duty Monitor Arm |
|---|---|
| Need a grommet hole mount instead |
For a Standing Desk Specifically
- A wide vertical height range to stay at eye level through sit-stand transitions, plus a clamp rated for your desk's edge thickness.
- You have a heavier or ultrawide monitor, where Ergotron Upgraded LX Pro Premium Monitor Arm's weight capacity and gas spring quality give real headroom over the cheaper picks.
- You have a light, standard monitor and just want basic height adjustment, where ErGear Single Monitor Arm covers the same job at a lower price.
Frequently Asked Questions
Do any of these monitor arms come with a built-in laptop tray?
Every arm in this list is a standard single monitor arm with a VESA mounting head. To add laptop support, you need a separate VESA-compatible laptop tray adapter, which is a common, inexpensive add-on rather than a special or rare part.
How much weight capacity do I actually need for a monitor plus a laptop?
Add your monitor's weight (roughly 5kg for a 27-inch panel) to your laptop's weight (roughly 3kg for a 17-inch model), then leave headroom above that combined total for the tray adapter itself. 8 lbs (about 9kg) work for lighter combinations, while a heavier setup should use the WALI, TitanLift, or Ergotron picks in this list.
Should I mount my laptop closed or open on a monitor arm?
It depends on whether you use the external monitor alone or both screens together. Closed-lid setups only need a flat tray positioned to the side, while open-lid setups need the tray angled toward you, which asks more of the arm's reach and swivel range.
Does mounting a laptop closed on a tray cause overheating?
It can during long sessions like video calls or rendering, since a closed laptop lying flat on a solid tray traps heat. A mesh or open-frame tray, or mounting the laptop vertically in clamshell mode if it has VESA mounting holes, vents better than a closed flat tray.
Will any VESA laptop tray adapter fit these arms?
As long as the tray adapter matches the arm's VESA pattern, 75x75mm or 100x100mm, it should fit. Every arm in this list lists its VESA pattern in the specs, so match that against the tray adapter's mounting spec before buying.
What size laptop tray do I need for a 16-inch MacBook Pro?
7 inch footprint, so look for a tray sized at least that large so the laptop doesn't overhang the edge. Pair it with a higher-capacity arm like the WALI, TitanLift, or an Ergotron pick to have enough combined weight headroom.
