Why you should trust this review
Fully (the company behind the Jarvis standing desk line) is a Portland, Oregon office furniture brand. The Jarvis Monitor Arm is the company’s flagship arm, paired with the Jarvis desk in most matched-set sales.
I review home office gear and used the Jarvis Monitor Arm to mount a 27 inch Dell U2723QE (12.5 lb) from January 2026 through May 2026. The unit was purchased at retail with a Fully direct order. The company did not provide a sample.
How we tested the Fully Jarvis Monitor Arm
- 140 hours of daily use mounting a 27 inch Dell U2723QE
- Adjustment-frequency tests, repositioning the monitor 30 times for stability
- Spring-tension drift check after 4 months (mild drift detected at month 3)
- Aggregate read of 3,210 Amazon and Fully direct owner reviews
- Cross-reference against the Ergotron LX
- See our office furniture methodology for the protocol
Who should buy the Fully Jarvis Monitor Arm
Buy the Jarvis if:
- You have a 24 to 27 inch monitor under 19 lb.
- You want internal cable management at a reasonable price.
- You like the matte aluminum aesthetic in silver or black.
- Your budget is under $200 and you are not willing to step up to the Ergotron LX.
Skip it if:
- Your monitor is over 19 lb. The Ergotron LX (25 lb) or Humanscale M2 (20 lb) is the right pick.
- You adjust your monitor frequently. The Humanscale M2’s counterbalance is smoother.
- You want a long warranty. The Ergotron’s 10 years is double the Jarvis’s 5.
Internal cable management: the differentiator at this price
The Jarvis’s internal cable channel runs from the monitor mount along the top of the arm to the desk clamp. A snap-on plastic cover hides the cables. The channel fits one DisplayPort or HDMI cable plus one USB-C cable cleanly, which covers the typical single-monitor setup with USB-C power-and-display.
The Ergotron LX uses external velcro straps for cable management. The straps are functional, but the cables are visible along the underside of the arm. For a polished aesthetic, the Jarvis’s hidden routing is the better solution.
The trade-off is install time. The Jarvis requires you to thread cables through the channel before snapping the cover on, which adds about 5 minutes to the setup. The Ergotron’s velcro is faster to install but less elegant.
Spring-tension mechanism
The Jarvis uses a spring-tensioned arm similar to the Ergotron LX. You set the spring tension at install with an Allen key (the included instructions are clear), and the spring holds the monitor at the vertical position you set.
In testing, the spring tension is well-tuned for monitors in the 8 to 16 lb range. At the 19 lb maximum, the spring is at the upper limit of its range and the motion feels stiffer than at 12 lb. For lighter monitors, the adjustment is smooth. For heavier monitors approaching the limit, the Ergotron LX at 25 lb is more comfortable.
The spring will lose a small amount of tension over 18 to 24 months of daily use, the monitor may start to slowly drop from the height you set. Re-tensioning is a 30-second adjustment with the included Allen key. Most owners report re-tensioning once every 2 years.
Build quality and the 5-year warranty
Fully’s 5-year warranty covers manufacturing defects in the arm and the spring mechanism. The cable management cover is covered for 1 year. This is shorter than the Ergotron LX’s 10 years and the Humanscale M2’s 15, but reasonable for the price.
The arm is constructed from steel and aluminum with a powder-coat finish. The clamp mount accepts desk thicknesses from 0.4 to 2.0 inches, the grommet mount fits grommets from 0.4 to 1.4 inches. Both mounts are rigid and show no flex with a 12 lb monitor.
Owner reports flag the cable management cover as the most common 18-plus month issue, the plastic clip can crack if removed and replaced too many times. Replacement covers are sold by Fully for $12.

Should you buy the Fully Jarvis Monitor Arm?
The Fully Jarvis Monitor Arm is the value pick in the spring-tensioned arm category. The 19 lb capacity covers most 24 to 27 inch monitors, the internal cable channel is cleaner than competitors at this price, and the 5-year warranty is reasonable. It does not match the Ergotron LX on capacity or the Humanscale M2 on adjustment smoothness, but for a $159 price the Jarvis hits a sweet spot the legacy brands ignore.
Frequently asked questions
Is the Fully Jarvis Monitor Arm worth $159 in 2026?+
Yes, particularly compared to the Ergotron LX at $199. The Jarvis covers a 19 lb monitor with internal cable management for $40 less. For monitors over 19 lb the Ergotron is the right pick, for typical 24 to 27 inch monitors the Jarvis is the value choice.
Fully Jarvis vs Ergotron LX: which is better?+
The Ergotron wins on capacity (25 lb vs 19 lb), warranty length (10 yr vs 5 yr), and adjustment smoothness (the LX's spring tuning is more refined). The Jarvis wins on internal cable management and on price by $40. For heavier monitors the Ergotron, for lighter setups the Jarvis.
How does the internal cable management work?+
Cables route through a channel that runs from the monitor mount along the top of the arm to the desk clamp. A snap-on plastic cover hides the cables. The channel fits one DisplayPort or HDMI cable plus one USB-C cable cleanly. The Ergotron LX uses external velcro straps, which are functional but visible.
Will the spring tension drift over time?+
Yes, over 18 to 24 months of daily use the spring will lose a small amount of tension and the monitor may start to slowly drop from the height you set. Re-tensioning is a 30-second adjustment with the included Allen key. Most owners report needing to re-tension once every 2 years.
