Fifteen minutes, free, no sign-in. It checks your desk, your height and your pain, then tells you whether a converter is the fix.
Most converters do the lifting badly: they wobble at standing height, stop short for tall people, or leave the keyboard too high. I scored 20 on the DEAS standard. These are the ones I'd put on a desk, then the full ranking.

If you can't replace your desk and your lower back is done by mid-afternoon, a converter is usually the first thing the people I assess reach for. It sits on the desk you have and lifts your keyboard and screen to standing height, so you can break up the long stretches of sitting.
The trouble is that most converters do the lifting part badly. Some wobble at standing height. Some stop short of a tall person's elbows. And on many, the keyboard deck and the screen shelf are fixed to each other, so getting one height right puts the other one wrong. A converter that reaches the right height but shakes every time you type hasn't solved anything; it has moved the strain to your shoulders.
What you want is one that reaches your standing elbow height, holds steady while you type, and lets the keyboard sit lower than the screen. That combination is rarer than the product photos suggest. Of the 20 I scored, one stands clearly above the rest. The 10 below are the ones worth your attention, ranked exactly as the numbers fell.

A converter's job is to let you change position through the day. Hours in one position, sitting or standing, keep the same tissues loaded with nothing to break it up; switching is what does. OSHA's guidance is the same: change your working position frequently through the day.1
In a small four-week study, office workers given a sit-stand device sat about an hour a day less and reported 54% less upper back and neck pain, and most of the gains were gone within two weeks of the device being taken away.2 The catch with converters is height. Set the keyboard too high and your wrists bend back to reach it: in healthy volunteers, about 33 degrees of that bend pushed carpal tunnel pressure over 30 mmHg, a common risk threshold, in a quarter of them.3
What that means when you shop
Buy one that reaches your standing elbow height, stays steady while you type, and lets the screen sit higher than the keyboard. Then use it: the switching is what helps, not standing all day.
1 of 20. Best overall
DEAS 7.6 out of 10
Electric lift with 21 inches of travel. The keyboard tray goes lower than the desktop; the screen sits on its own mount.
This is the converter I point people to when a wobbly converter is part of the problem. A motor does the lifting, the keyboard tray goes lower than the desktop so your hands can sit at elbow height, and the screen sits on its own mount above it. It ties for the top height-range-and-stability score and has the top score of any converter we've rated.
Good: the top score here; an electric lift with a keyboard tray that goes below desktop height; meets the ANSI/BIFMA X5.5 desk standard; a 15-year warranty. Less good: priced further above the category benchmark than any converter here; too few reviews for a reliability score.

2 of 20. Best wide surface
DEAS 7.0 out of 10
Spring-assisted lift with 11 settings, 4.5 to 17.5 inches. 36 inches wide, with a lower keyboard deck.
If you run two monitors or spread papers out, this has the deck to do it without your keyboard creeping toward the edge. It's a proven, well-built design. Know the trade-off: the keyboard deck sits a fixed 4 inches below the top.
Good: a 36-inch top with room for two screens; tested to BIFMA standards and GreenGuard Gold certified; a lifetime warranty. Less good: keyboard and screen tiers rise together, so their heights can't be set separately; priced above the category benchmark.

3 of 20. Best for wrist-neutral typing
DEAS 7.0 out of 10
20 inches of lift, down to within 2 inches of the desk. A drop-down keyboard tray below the work surface.
This is the one I recommend when wrists are the main complaint. The keyboard tray drops below the work surface, which is the geometry that lets your hands sit at elbow height while the screen stays up where it belongs. If your forearms ache more than your back, it solves the right problem.
Good: a drop-down keyboard tray for typing at elbow height; ties for the top height-range-and-stability score; stepless height adjustment. Less good: a low certification score; priced well above the category benchmark; the typing area sits about 9 inches out past the desk edge, so you need room in front.

4 of 20. Best value
DEAS 6.8 out of 10
Gas-spring X-lift, 4.7 to 20.1 inches, with a separate keyboard tray.
The one I steer people to when budget matters. It has the best price score in the top five, and the basics hold up: a separate keyboard tray, a wide height range and a gas spring you can work with one hand. You give up some build polish against the names above it, not the things that matter for your body.
Good: the best price score in the top five; a separate keyboard tray; a 4.7- to 20.1-inch range. Less good: a lower height-range-and-stability score than the leaders; the gas spring and mechanism are covered for 3 years, the frame and top for 5; no certification listed.

5 of 20. Best build quality
DEAS 6.8 out of 10
Freestanding, moved by hand with no levers or buttons. 18 inches of travel, plus 5.5 inches of monitor height.
If you want the most refined hardware and price isn't the deciding factor, this is it. There are no levers or buttons: you move it by hand and it holds where you leave it. The screen adjusts separately from the work surface, which makes it easier to get both heights right. The price is where its score takes the hit.
Good: ties for the top build score; screen height adjusts separately from the work surface; no levers, buttons or clamps; single, dual and triple monitor versions. Less good: priced above the category benchmark; tied for the lowest reliability score in the top ten.

6 of 20. Electric runner-up
DEAS 6.3 out of 10
Electric X-lift, 5 to 20 inches, with a separate keyboard tray.
For someone who wants a motor doing the lifting without paying for the E7. It rises at the press of a button and has its own keyboard tray. The clinical scores are middle-of-the-road, so treat it as a convenience pick rather than a posture upgrade.
Good: an electric lift with a better price score than the E7; a separate keyboard tray; a lifetime frame warranty. Less good: the motor is covered for 3 years; a low certification score; a low reliability score from user reviews.

DEAS 5.6 out of 10
Gas-spring lift, 6.3 to 17.5 inches, with a separate keyboard tray.
If the FlexiSpot M7 is sold out, this is the closest swap: a two-tier gas-spring converter with the same price score. The clinical scores are adequate rather than strong, so I'd use it for a second desk or part-time standing, not eight hours a day.
Good: a good price score; a separate keyboard tray; a fair reliability score from user reviews. Less good: its lowest setting, 6.3 inches above the desk, is the highest in the top ten, which matters when you sit; no third-party certification; a low warranty score.

DEAS 5.5 out of 10
Electric lift, 5.7 to 18.1 inches. A 36 by 24-inch top with a retractable keyboard tier.
A budget way into a motorized converter. The top is big enough for two monitors and the keyboard tier slides away when you don't need it. The modest build score is why I'd only pick it if a motor is non-negotiable and the budget won't stretch.
Good: an electric lift with a better price score than the other electric picks; a top big enough for two screens; a retractable keyboard tier. Less good: a below-average build score; no third-party certification; a low reliability score from user reviews.

DEAS 5.2 out of 10
Gas-spring lift, 1 to 16.8 inches. One 26.8 by 13.4-inch surface for a laptop, rated to 11 pounds.
I'll be straight with you: this ranks here on price and warranty, not on clinical performance, which is the weakest in the top ten. It's made for a laptop on a cramped desk and standing now and then. It is not the fix for a serious back problem.
Good: one of the best price scores here; a 15-year warranty; no assembly. Less good: the lowest clinical scores in the top ten; one surface, so the screen and keyboard can't both be at the right height; an 11-pound limit means a laptop, not a monitor; too few reviews for a reliability score.

DEAS 5.2 out of 10
Staples' house-brand converter, and a fair price for a manual lift. Its scores are middling across the board and its warranty score is low, so treat it as an inexpensive way to find out whether standing helps you before you spend more.
Good: a good price score; a simple manual lift with nothing to plug in. Less good: no third-party certification; a low warranty score; too few reviews for a reliability score.

Composite 5.2 on the DEAS (Desk Ergonomics Assessment Score). How we score
Find your standing elbow height. Stand naturally, shoulders relaxed, elbows bent about 90 degrees. That is where the keyboard belongs, not where the desktop happens to be.
Bring the keyboard to it. Forearms level with the floor or sloping slightly down, wrists flat, not bent up toward the screen.
Top edge of the screen level with your eyes. If the screen and keyboard rise together, lift the screen with a monitor stand or arm.
Pull the keyboard in. Close enough that your upper arms hang by your sides. Reaching forward brings the shoulder load straight back.
Check it sitting, too. Fully lowered, a converter still sits on your desk, so the keyboard can end up too high when you sit. Lower it all the way and check your elbows.
Stand on a mat. A cushioned mat makes the standing part more comfortable.4
Alternate. Switch every 30 to 45 minutes. Start with twenty minutes of standing at a time and build up as your legs adapt.
The mistake I see most
People raise the converter to a comfortable-looking desktop height and type with their wrists bent up. Set the keyboard to your elbows first, then bring the screen up to your eyes, in that order.
Feels like
A dull ache low in the back that builds through the afternoon.
What helps
Break up the sitting. A converter that reaches your standing height lets you switch every half hour or so.
Feels like
Burning or tightness in the wrists and forearms, often from a keyboard set too high, which bends the wrists back.
What helps
Keyboard at elbow height, not desktop height. A converter with a lower or drop-down keyboard tray helps most.
Feels like
Stiffness across the shoulders and the base of the neck from a screen that sits too low.
What helps
Raise the screen until its top edge is level with your eyes. If the converter won't, add a monitor stand or arm.
Three things, in order. Height range: it has to bring the keyboard to your standing elbow height, which is where tall people get let down most. Stability: it should stay steady at full height while you type. Then a keyboard tier that sits below the screen, or a screen you can raise separately, so you aren't choosing between bent wrists and a low screen. Build and warranty decide how long it lasts; those three decide whether it helps.
Not quite. A standing desk moves the whole surface as one solid piece, and at its lowest it's an ordinary desk. A converter sits on top of your desk, so even fully lowered it can leave the keyboard too high when you sit, and most lift a smaller surface on a spring or scissor mechanism. When you can't replace your desk, a good converter closes most of that gap. If you're buying new, a standing desk is the cleaner fix.
Less than you'd think, and never all day: standing still for hours brings its own aches. What helps is changing position, and OSHA's guidance is to do that frequently through the day.1 I start people at about twenty minutes of standing at a time and have them switch every 30 to 45 minutes. A converter makes the switch quick enough that you'll actually do it.
Almost always because it's set too high. People raise it to a comfortable-looking height and type with their wrists bent back toward the screen, and that bend raises the pressure in the carpal tunnel.3 Set the keyboard to your elbow height, forearms level with the floor. If your converter has one fixed surface, a model with a drop-down keyboard tray, like the Ergotron WorkFit-TX, fixes it properly.
Ten more, all in the ranking above. The best of them, the Mount-It! Electric and the Rocelco 32-inch, score 5.1, just behind the Union & Scale FlexFit at number 10. All ten score 2 out of 10 for both certification and warranty.
