The iMovR SteadyType Exo keyboard tray shown in Bella Walnut and attached to a standing desk.


Review Summary

The SteadyType Exo is an overachiever. Its raft of awarded patent claims is just the start. Among ergonomic keyboard trays, it is not only the most stable and durable design we’ve ever tested, the easiest to install, and the best at achieving steep “negative” ergonomic tilt angles; it is all of those things by a large margin. While the SteadyType Exo does not offer the ability to retract your keyboard underneath the desktop, its ability to install in just 30 seconds to literally any standing desk with a straight front edge, and to accommodate virtually any combination of keyboard and pointing device imaginable, forges a new and exciting category of adjustable keyboard trays. We can state categorically that it is the most ergonomically versatile add-on keyboard tray for standing desk and treadmill desk users on the market today.

Best Use

Any standing or treadmill desk user looking for impeccable stability, ease of installation, and much steeper tilt angles than typically available in adjustable keyboard trays.

Ease of Assembly
Positives A testament to American R&D and manufacturing quality, the SteadyType Exo is incredibly stable—the most stable ergonomic keyboard tray we’ve tested by an order of magnitude. Installation is astonishingly quick and easy. We’re talking 30 seconds versus the usual hour+ ordeal of installing a keyboard tray. Not limited to the usual +10°/-15° of tilt, this tray can literally rotate 360° (but practically speaking can hold the keyboard and mouse in place up to a near-vertical -85° of tilt). The luxuriously 3D-laminated keyboard platform can accommodate any keyboard and any keyboard/pointing device setup imaginable. Clever “bumpers and pins” allow you to position the keyboard and pointing device as close to your body as possible, to prevent forward shoulder rolling and keep your posture upright.
Negatives There is no way to retract the keyboard under the desk with this kind of tray, it is fixed in place (though technically can be removed in seconds, or even ported between different desks). The attachment clamp requires a straight front edge so it will not work for standing desks like the UpLift Eco Curve that have a concave contoured user edge or at the “inside elbow” of an L-desk. The price is high compared to far inferior commodity keyboard trays made in China, albeit those do not have the ability to achieve truly neutral typing angles needed for standing desk or treadmill desk use.

Bottom Line

Ergonomic keyboard trays, which haven’t changed much from their original designs of the 1980’s, haven’t adapted in any meaningful way to the new ergonomic requirements of the standing desk or treadmill desk user. Besides the ergonomic differences, there’s a crossbar running under the desktop of most standing desks that interferes with the installation of any conventional keyboard tray’s slide rail. For those reasons the vast majority of active workstations currently lack a keyboard tray altogether. From our first look at the SteadyType Exo, it clearly stuck out from the crowd because it’s not inherently wobbly, and it’s not an hour-long chore to install. Its primary ergonomic benefit of being able to achieve much steeper (i.e. more “neutral”) tilt angles than the conventionally-limited -15° is one of several patented features that no other tray offers. In the glacially slow-changing field of ergonomic keyboard trays the SteadyType Exo is the new “killer app.” It is the latest of several SteadyType-based innovations founded upon iMovR's groundbreaking research in 'ergodynamics'.

What’s the Actual Point of Having a Keyboard Tray?

An ergonomic keyboard tray (a.k.a. “articulating keyboard tray,” “adjustable keyboard tray” or abbreviated simply as an “AKT”) is any keyboard tray that corrects two problems caused by placing your keyboard directly on your desk.

The first problem it solves is height—without a keyboard tray, most desktops are too high for strain-free typing, causing you to engage muscles that should be more relaxed. Just about any under-desk keyboard tray will alleviate this issue.

The second problem an ergonomic keyboard tray addresses is tilt. For your wrists to be properly aligned, your keyboard should be able to achieve a “negative tilt” of -10° to -15° when seated at a fixed-height desk. The only reason for not going any steeper at a fixed-height desk is that your lap is in the way.

SteadyType Exo ergonomic keyboard tray

The AKTs of yore were designed to overcome the innate inadequacy of sitting desks, allowing you to type in a way that’s a little more neutral for your wrists, elbows, and upper body. This decreases the likelihood of developing RSIs (repetitive strain injuries) such as carpal tunnel syndrome.

But when you’re working at a standing desk or treadmill desk—without your chair’s armrests to support the weight of your forearms—the concept of a “neutral” elbow angle changes from the inherently limited -100° to -105° to a much greater angle, up to -140° or even more, to relieve muscles from the strain of gravity pulling the forearms downward as much as possible.

Or, more practically speaking, “the steeper, the better” to avoid RSIs while maximizing your typing comfort and proficiency (i.e. your typing speed and rate of committing typos).

The ability to retract the keyboard under your desk is a common feature of AKTs, but technically not related in any way to ergonomics. A simple keyboard drawer will take care of that much less expensively. In fact, many people who inherited a keyboard tray at their work desk never even learned how to set its angle for proper ergonomics (many, in fact, use their keyboards at an ergonomically-egregious positive tilt inclination out of common ignorance), and only appreciate it for its retractability.

So for the rest of this review, we’re going to limit our discussion to a keyboard tray’s ergonomic functions, since retraction ability is the one thing you won’t get with the SteadyType Exo. That said, it takes only seconds to remove temporarily from any desk, so even if you do occasionally want to make the keyboard disappear, it is trivial to do so.

Enter SteadyType and ‘Ergodynamics’

iMovR already changed the ergonomics game in standing desk and treadmill desk ergonomics with their SteadyType technology, originally patented in 2014. iMovR’s groundbreaking research in this area helped spawn the ergonomic subspecialty of ‘ergodynamics‘, which encompasses the different body positions and motions of a computer user in motion, i.e. when standing or walking, not sitting in a chair. This includes research into keyboard trays, monitor arms, anti-fatigue mats, and other ergonomically-focused design elements of standing desks and treadmill desks.

Specifically, regarding keyboard placement, the basic concept is that while you’re in the upright position (either standing or walking), the most ergonomically neutral, non-straining position for your arms is akin to the posture of a sleeping astronaut—with elbows bent not at 90° like most standing desk advertisements show, but with your arms resting closer to your sides and your elbows at wider angles, typically 115° -140°.

The SteadyType Exo is the only keyboard tray on the market that accommodates what ergonomists who were actually trained on standing desk and treadmill desk ergonomics consider truly neutral arm angles. For more on adjustable keyboard tray options for treadmill desks, see our primer on the subject. After testing many of iMovR’s SteadyType-equipped desks in the past (including the Lander, Cascade, Denali, Olympus, and Everest), there is a marked difference in terms of typing endurance especially; a SteadyType-equipped desk allows the user to type for hours at a time, while a normal flat-surfaced standing desk leads to faster fatigue.

Now with the SteadyType Exo, you can garner these benefits on virtually any existing standing desk.

Negative tilt is perhaps the single most important concept that many users, and even salespeople and websites that sell keyboard trays, get reversed in their minds. It’s easy to understand why this happens. The very word “negative” sounds counter-intuitive. But, in fact, it’s a negative tilt, as shown in the photo on the right, above, that you want to achieve with an ergonomic keyboard tray.

The only application for positive tilt is typically for gamers who want to lean way back in their chairs and still be able to see and reach their keyboards. And for those gamers the SteadyType Exo has infinite adjustability, not limited to just a 10° positive tilt range.

In general, keyboard trays allow you to tilt the edge of your keyboard that’s closest to the user up, bringing it into a negatively-inclined position from the perspective of where your wrists are resting on the user edge of the keyboard. While this may depart from old-school, pre-ergonomic keyboard design (pop-up tabs on many keyboards used to let you elevate the back—a humongous ergonomic no-no) it’s actually ergonomically proper to tilt the keyboard the other way.

It’s only by placing the keyboard at a negative tilt that wrist flexion—and consequent squeezing of the carpal bones that surround the nerves and blood vessels that pass through them—can be neutralized. We’ve never been able to figure out how the computer industry started down this path of tilting keyboards in exactly the opposite direction as is ergonomically correct; the myth has persisted for decades and millions of computer users are still unaware.

Because the SteadyType Exo rotates around a metal pipe, you can technically achieve a full 360° rotation. The tilt options are only limited by how well your keyboard and mouse can remain on the tray. We were able to tilt the Exo down to a near-vertical 85° without losing the keyboard or mouse off the tray. Its innovative method of holding onto these peripherals at such steep angles is one of the patented aspects of the design.

The Usual Problems with Ergonomic Keyboard Trays

Knowing what ergonomic keyboard trays are supposed to accomplish, let’s see what often gets in the way. We looked at the negatives from all of our keyboard tray reviews over the years, and two issues consistently bugged us: Difficult installation and shakiness. Of course, there were many other frequent issues like no negative tilt (literally Chinese knockoffs that got the rotation direction reversed), difficult adjustment, lack of fencing to keep peripherals from sliding off the tray, etc., but it almost always came back down to that pair of fundamental issues.

Ergonomic keyboard trays are usually hard to install and they are usually very “floppy” due to the combination of loose joints in the mechanism, from the glide rail to the adjustable arm to the cheap, flexible plastics (typically phenolic) used to construct the tray itself.

The SteadyType Exo is the exception to those rules.

Ergonomic Keyboard Trays are Usually Hard to Install

Anyone who has ever installed a keyboard tray knows what a project it can be. First, you have to flip your desk over, drill pilot holes using a paper template, screw in the slide rail, assemble the keyboard arm, slide it into the rail, and install the rail stop hardware. And that’s if you don’t have to redo the job because you eventually realize that the keyboard tray is centered on the monitor and not on your Numpad-equipped keyboard, leading you to have to undo it and reinstall the tray a few inches over to the right. Bottom line, it’s never a simple task.

SteadyType Exo ergonomic keyboard tray

We’ve come across many products with hyperbolic claims about assembly time, but the SteadyType Exo truly nails its proclamation of 30 seconds (see the video for the full installation). It has a long edge clamp that is secured to the user edge of your desk with just two knobs. Two more knobs, set eight inches back from the user edge of the desk, allow you to perfectly level the SteadyType Exo in case the tabletop has a lip on it.

The SteadyType Exo is technically portable in the sense that you can uninstall it very quickly—it’s the opposite of the 30-second process to install. Because of its size and weight (15.5 lbs), you wouldn’t want to carry it around often, though you could if you wanted to share it between two desks or multiple users.

Ergonomic Keyboard Trays are Usually Shaky

SteadyType-based keyboard trays are in an entirely different stability class compared to traditional keyboard trays. iMovR produced the video below to show just how solid SteadyType Exo is by dropping increasingly large and heavy fruit on the tray, compared to other popular tray models being put through the same torture test. 

This is one of those instances where we couldn’t come up with 1,000 words to describe the Exo’s stability better than a picture could, so it’s probably better to just watch the video and see for yourself. This thing is a rock. Because of the strong connection between the tray and the desk, any shakiness we felt was inherent in the desk itself, not the tray.

Like any keyboard tray, adding a SteadyType Exo will create a longer “moment lever” on the desk. It sticks out from the desk about 12” and will exaggerate any instability that already exists in the desk. While it can’t solve the physics inherent in any 2-legged standing desks (see our primer on Why Some Desks Are Shakier Than Others) it at least won’t add to any instability of the desk at taller heights.

Inspecting the SteadyType Exo up close, it’s clear the construction pays off. Other ergonomic keyboard trays often sneak things in like hollow plastic keyboard platforms or obviously floppy joints, all in the name of cost reduction. These shortcuts aren’t present in the SteadyType Exo. The construction looks and feels top-notch. The design also avoids the accumulation of tolerances of each joint that lead to shakiness with most ergonomic keyboard tray designs that feature the typical rail, swivel point, arm, keyboard platform, and sometimes mouse platform.

More Color Choices Than Any Other Keyboard Tray

Most keyboard trays come any color you’d like, as long as it’s black. A few, like the premium trays from Humanscale, come in black, white or silver. The SteadyType Exo has initially been released with a whopping six color options.

The keyboard tray itself is gorgeous, finished in the same exclusive Surf(x) 3D laminate that iMovR has been using for many years to make their standing desk work surfaces. The surface is pleasant to the touch and extremely resistant to damage from scratches, dents or even cleaning chemicals while looking pretty.

As far as color options go, basic Black and Designer White are offered as these colors won’t clash with any color of desk. For woodgrain, iMovR so far offers Light Maple, Hayward Cherry, Bella Walnut, and Obsidian Oak—the most popular colors on their standing desks. The soft radiused edging on the tray gives these woodgrain laminates the appearance of being carved out of natural hardwoods.

The steel frame of the SteadyType Exo is powder coated in a durable, matte finish, with solid weld joints. Like the tray, all components are made in the USA (Michigan, specifically). The four clamping knobs and the main adjustment knob for setting the tilt angle of the tray are easy on the hands, with rubber grips to make them extremely easy to turn.


We spend a lot of time talking about the available “draft” your desk needs to have underneath the desktop to accept a keyboard tray’s installation (we even wrote an entire primer on the subject of adding an adjustable keyboard tray to a standing desk). Because most adjustable-height desks have a crossbar running between the tops of the lifting columns, there just isn’t enough space for the rail of many keyboard trays to fit (although there are now some products that allow you to get around this issue). That’s why most standing desks do not have an ergonomic keyboard tray installed.

The SteadyType Exo needs only 8.25” of draft, so it will not interfere with the crossbar on any adjustable height desk. Its draft required is less than other ergonomic keyboard trays we’ve reviewed that were specifically designed for adjustable-height desks like the Humanscale Float (12”) or even the iMovR Trackless (9”).

This universal fit with crossbars is a big deal. It’s one less dimension to consider for fit, especially since that dimension isn’t always easy to find in advertised features (or even correct when you do find it, like in the case of the Seville Airlift 360).

There are some limited desk situations where the SteadyType Exo won’t fit well, like an UpLift desk with an Eco Curve. An L-desk with a curved work surface where the left and right sections of the desk meet will create a similar challenge to installation.

Bumpers and Pins

The SteadyType Exo comes with four rubber bumpers that can go into any of the seven slots on the tray. The primary purpose of these is to keep your keyboard from sliding off the tray when it is at steeper angles.

SteadyType Exo ergonomic keyboard tray

A secondary purpose is to allow you to keep the keyboard as close to the user edge as possible. This is an ergonomic feature we haven’t found on any other keyboard tray yet. The idea is to keep your shoulders as far back as possible, thus reducing our propensity to get into a “computer hunch” posture.

The bumpers can slide back and forth in any of the seven slots to fit the back-edge contour of the keyboard design. We tried every keyboard/pointing device setup we could imagine being used and they all worked perfectly with these bumpers. This includes split keyboard halves (each keyboard half can even be individually canted to eliminate the dreaded “ulnar deviation” that instigates carpal tunnel syndrome).

The platform is 28” wide, which will fit any keyboard on the market—even larger ones like the popular Microsoft Natural 4000—as well as any kind of pointing device, from a mouse to a trackball or even a large trackpad.

There are three “zones” where you can put the three pins that hold your pointing device in place. The zones are for right-handed and left-handed users, plus a center zone for anyone with serious ergonomic shoulder or elbow injuries who needs their pointing device planted between split keyboard halves.

We found this to work well once you get past the brief hesitation of trusting your mouse will slide to the nest of pins and not fall off the tray when you let it go. There is a small learning period where you have to get used to retrieving the mouse every time you want to use it since it’s in a different spot than where you left it. The movement feels completely natural after just a few minutes of use and overall the SteadyType Exo is very easy to use.

Whatever Happened to the Elevon?

If you’ve been reading our reviews for a few years you might recall that iMovR did have a somewhat similar product that it launched on Kickstarter in 2017 called the Elevon. We were just as excited about its introduction as we are the SteadyType Exo four years later, but it was definitely aimed at a much narrower market.

The Elevon remains the most adjustable keyboard tray ever created, and ergonomists love it for its ability to solve hard-luck ergonomic injury cases when no other keyboard tray can. Alas, it turned out to be too large, too heavy and too expensive for the mass market. The SteadyType Exo was designed for mainstream users who don’t need quite that much heft in their keyboard tray.

The Elevon is currently unavailable from iMovR as it is being redesigned to make the “wing panels” optional, to lighten the size, weight and cost of the unit.

Quality Construction, Solid Warranty and 100% Factory Pre-Assembled

The Exo’s manufacturing quality is evident in every component, as we already described above. The warranty reflects this with its lifetime coverage of the metal frame and five-year coverage on the 3D-laminated tray (same as on iMovR’s desktops). Like most iMovR products the Exo also comes with a 100-day satisfaction guarantee.

The tray arrived in robust protective packaging, already fully assembled. Video instructions make it easy to set up the Exo for any conceivable combination of keyboard and pointing device.

The Takeaway

As far as negative tilt capability, ease of installation, and stability, it’s not hyperbole to say the SteadyType Exo has changed the game for standing desk and treadmill desk keyboard trays. The Exo was clearly designed and made with one thing in mind: Improving your ergonomics while typing at an active workstation. And it will do just that. No caveats.

SteadyType Exo ergonomic keyboard tray

We didn’t find any notable negatives of the design other than its lack of retractability. And we recognize that the components that make a tray retractable also empirically detract from its stability. However, this lacking feature is fairly well negated by the ease with which you can remove the tray. Again, installing and uninstalling really is as easy as it sounds. In fact, 30 seconds might even be an overestimate.

The ability to easily achieve steeper, more neutral negative tilt positioning of the hands and forearms while remaining rock-solid stable, makes the SteadyType Exo far and away the top ergonomic keyboard tray for standing and treadmill desks.
