I was very excited to get the opportunity to try the Jarvis electric standing desk. It has been the reigning champion of the The Wirecutter’s Best Standing Desk award three straight years. With all of the hype surrounding it, I definitely had high expectations. The Wirecutter was even quoted as saying this about Jarvis (and Uplift), “Both desks show more polish in their details and are far more stable than anything else in their price range.” Of course, like most things in life, if you set expectations too high you’re bound to be disappointed. Now that we’ve tempered those expectations, let’s take a closer look at the Jarvis desk.
OEM Manufacturer for Jarvis Desks
Like many of the other standing desks on the market, Jarvis is not being produced by the actual brand itself. All of the Jarvis desks are currently manufactured by the popular Chinese company, JieCang Linear Motion. This is the same company that produces the Uplift 900 Standing Desk and The Evo Standing Desk. They have been producing linear actuators for hospital beds and accessories since early 2000 and in 2011 they saw an opportunity to produce adjustable bases. Using their linear actuator technology within metal desk frames, the JieCang standing desk was born. They are currently the leading Chinese manufacturer of electric standing desks.
Jarvis Desk History
The Jarvis desk brand was introduced in 2013. Fully (formally ErgoDepot) has made multiple changes to the product, including a switch from the T-base to the C-base now being used. They have also updated their foot design to include a more robust steel foot design.

Jarvis Desk Packaging
The overall packaging was very good, with cut foam used for extra protection. The box itself was heavy, which means there was a solid product inside. The Jarvis came in the same box as the Uplift Desk, but with different logos.
Assembly (30-90 Minutes)
The assembly for the Jarvis Desk was fairly straightforward. Similar to other JieCang bases, there are a lot of screws. Some screws can be difficult to insert and tighten. Jarvis included a small booklet with a link to a video on their website for assistance. Because you have to assemble the upper frame, upper desk top supports and attach the feet to the columns (legs), assembly of the base took approximately 30 minutes. Attaching the upper supports to the column (leg) might require an extra pair of hands; make sure not to fully tighten these screws until all of them have been inserted properly. After all screws have been inserted you will want to make sure the screws are very tight.
The screws to assemble the steel feet to the base were very easy to access and fully tighten. Unfortunately, the way the feet are attached with four screws and no lock washers means they will likely become loose over time. If you notice movement coming from the bottom of the leg/foot, this is likely to be the cause. Be sure to tighten as much as you can for stability. We recommend the use of a product like Loctite Threadlocker for a better hold.
Attaching the base to a desk top took another 15 minutes, which included the electronic components and standard wire management (included free). Depending on your skill level the complete assembly could require a bit more time.
The Jarvis has a sleek look without the use of a traditional cross support. The movement was smooth and while in operation there is a low humming sound that comes from the two motors encased within each leg. The motors had the capacity to move heavy weights with ease; however, the desk became very wobbly left to right when raised above 40”. I also noticed that the grease they use to lubricate the legs started to leave a white residue on the columns after the first cycle. As the desk continued to cycle it started to show quite a bit more. Similar to the other JieCang bases, the Jarvis desk also stays in motion for about .5 seconds after the up/down button was released.
The Jarvis desk was the second JieCang base I tested, after the seeing the Uplift I had expected similar stability from their base. I quickly found out this was not the case and the design of each base made them polar opposites. The Jarvis was much less stable than the Uplift, specifically left to right when moved above 40”. I must be honest. We don’t have a scientific test that we perform on each desk; however, we are able to get a good idea of stability by feel and visual, using cup of water.
Front to Back: The desk was very solid below 44”. Once it rose above that point, I could see the entire base starting to flex forward and backward. This allowed the desk to have a noticeable movement. It became more so the higher you went with the desk, and after 47” the lack of overlap from the three columns was obvious. This is a common issue with adjustable standing desks and each desk has a different height at which you will begin to notice it.
Left to Right: This movement was something to be expected without a traditional cross support; however, I was surprised that it started to wobble as early as 36”. Once it was raised to 40” it became an annoyance. The lack of the wedge found in the upper portion of the column (between the motor and leg) make this version of the JieCang frame much less stable.
Note: It’s very important with all adjustable standing desks to fully tighten all hardware. If there is hardware that is not completely tight the movement experienced when extended to standing height will be exaggerated.
Testing the Specifications
Listed Height Adjustment Range: 22.25” – 48.75”
I found this to be true. The height range with the leveler glides and various thicknesses of tops was accurate.
Travel Speed: 1.5” Per Second (Claimed)
This was not true. I was able to average 1.32” per second over 10 cycles with a 50 lbs. desk top attached. This is consistent with other JieCang desks that we have tested.
Noise Level: 50 Decibels While in Motion
I found this reading to be accurate. While it is noticeable in a quiet room, it isn’t an annoyance and wouldn’t be an issue for most people.
Weight Capacity: 350 lbs.
It had no problem lifting 350 lbs. It only slightly affected its performance, slowing to 1.25” per second. Unfortunately, the lack of stability left to right would be a concern with a lot of weight on the desk.
What I Like About the Jarvis Desk
Range of Motion: The 26” of travel allows the Jarvis Desk to be used by a wider range of people. Because the column goes into the foot, as opposed to being mounted on top, it allows the desk to go as low as 23.25” without a top. Depending on the thickness of your desk top, this will allow users 5’4” to sit comfortably at this desk. While this reduces the top end height to 48.75” without a top, it will still fit most users up to 6’8” comfortably.
Lifting Capacity: With a 350 lbs. rating, the Jarvis Desk has plenty of capacity. Most users will require 150-200 lbs. capacity, including the desk top and all accessories. Even with a max load tested, the Jarvis Desk’s performance remained consistent, dropping from 1.32”/ second to 1.26”/second.
7 Year Warranty: Jarvis’s 7 year warranty that includes electronics and structural components is very good. It is an industry leading warranty that requires tremendous trust in their product. We commend them for offering this to customers.
What Could Be Improved Upon
Traditional Cross Support: I was very surprised how the Jarvis desk began to wobble at only 36”. The left to right swaying became an annoyance at 40”. Unfortunately, the frame that runs below the desk top is too high up on the columns and the lack of a wedge like the one found on Uplift really impacts its stability.
White Grease on Columns: This isn’t something that will affect the function of the desk; however, if you were to bump into the desk at the office in dress clothes it would be a problem. There are alternatives that are much less messy and provide a more finished look.
Continued Motion after Releasing Button: This is a safety concern, as the desk should stop when you release the button. Things like fingers, children and furniture all come to mind when watching the desks continued movement.
Additional Questions I Have
Why This is The Wirecutters Top Pick: It’s hard to understand why Wirecutter continues to pick the Jarvis. After only a few minutes with both Jarvis and Uplift our findings were completely opposite. The Uplift desk is the clear winner when comparing these two JieCang desks.
Why the Desk Speed is Inaccurate: Fully.com lists 1.5” Per Second speed when JieCang shows on their specs it is 1.38” per second (35mm/second).
Weight Rating JieCang Recommends: The manufacturer lists two separate weights for this particular product. One weight is for a single column, which is listed at 800N (179.847 lbs.); however, when two are combined the capacity is only 1000N (224.808 lbs.). This leads us to believe that while the motors are strong enough to lift 360 lbs., they do not recommend it with the current configuration. This is supported by the amount of left to right wobble experienced during my testing.
After getting a chance to take a closer look at the Jarvis Desk, my perception of the desk has changed a lot. Unfortunately, its large adjustment range of 26” and all-inclusive 7 year warranty are not enough to eliminate my concern for stability above 40”. The lack of attention to detail with regards to the white grease, and additional safety concerns that exist with the movement that occurs after releasing the buttons, push it further down the list. Overall I feel that when compared to its direct competitor, the Uplift Desk has a clear edge with these two top selling JieCang products.
