A flat keyboard bends your wrists out toward your little fingers, and back toward your forearms if its feet are up, for hours. A split or contoured one straightens them. I scored 53 on the DEAS standard; these are the ten I'd put in front of you, then the full ranking.

Desk Doctor earns a commission on some links, at no cost to you. It never changes a score. How we make money
When someone comes to me with wrist pain, forearm tightness or tingling fingers, the keyboard is one of the first things I check. A standard keyboard keeps both hands close together, so your wrists angle out toward your little fingers to reach the keys, and if its back feet are up, they bend back too. OSHA flags both.1
The fix is geometry. Split the keys and your wrists can line up with your forearms; tent them and your forearms don't have to lie flat; tilt the board away from you, or keep it flat, and your wrists stop bending back. Switches, macros and lighting are preferences.
Of the 53 keyboards I scored, three tie at the top, and the Cloud Nine C989M is the one I'd start most people on. If you want the contoured design, buy the Kinesis Advantage360: the Advantage2 is being wound down.

Two wrist positions matter most: bent back, and bent sideways toward the little finger. OSHA's guidance is wrists straight and in line with your forearms, and it warns that a traditional keyboard can bend your wrists sideways and that raised keyboard feet can bend them up.1
The angles matter because of the carpal tunnel. In healthy volunteers, about 33 degrees of wrist extension, or about 15 degrees of sideways bend toward the little finger, pushed carpal tunnel pressure over a common risk threshold in a quarter of them.2 In a lab comparison of six keyboard designs, the one that held wrists and forearms closest to neutral had a moderate fixed split of 12 degrees, a moderate tent of 14 degrees and no slope, though people typed fastest on the conventional keyboard they knew.3 Tilting the keyboard away from you straightens the wrist: in a typing study, a negative-slope support cut average wrist extension from 13 degrees to about –1.4
What that means when you shop
Even OSHA is careful here: these keyboards keep wrists closer to neutral, but the research hasn't shown they prevent discomfort or injury.1 Buy the shape your symptoms call for, then set it up well.
1 of 53. Best overall
DEAS 7.7 out of 10
Two halves that separate up to 6 inches; a built-in 7-degree tent; full size with a number pad; Kailh Box mechanical switches; molded palm rests.
The keyboard I'd start most people on: a true split you can pull apart to your shoulder width, with a gentle built-in tent and palm rests, in a full-size layout with a number pad. It ties for our top score, and its price score is far better than the contoured keyboards'.
Good: halves that separate up to 6 inches; a number pad; mechanical switches; one of the best price scores here. Less good: the tent is fixed at 7 degrees; too few user reviews yet for a reliability score; no third-party certification.

One piece with a built-in split and tent; compact, no number pad; 5-degree negative tilt; washable palm rest; Gateron switches at 45 or 55 grams. 2-year warranty.
A compact split in one body: the keys are split and tented inside it, and with no number pad, your mouse sits closer to you. It ties with the C989M on every one of our scores, and it's the gentler step for most people.
Good: compact, so the mouse stays close; a built-in split, tent and negative tilt; a choice of light switches; a 2-year warranty. Less good: the split is fixed; too few user reviews yet for a reliability score.

DEAS 7.7 out of 10
Two concave key wells tented at 20 degrees; thumb keys; no number pad; Cherry MX Brown switches at 45 grams; programs on the keyboard itself. 3-year warranty.
The contoured design puts each hand in its own bowl, tented 20 degrees, with the modifier keys moved under your thumbs. It ties for our top score. The catch: Kinesis announced in January 2026 that it's winding down production, so buy one while you can find it, or step to the Advantage360.
Good: concave key wells; modifier keys under your thumbs instead of your little fingers; light 45-gram switches; a 3-year warranty. Less good: production is winding down; priced well above the category benchmark; a real learning period.

DEAS 7.6 out of 10
Contoured key wells in two separate halves, 15.25 to 21.25 inches apart (wired); three tent settings; a wireless Pro version. 3-year warranty.
The contoured design split into two halves, so you can set them to your shoulder width and tent them at three heights. For broad shoulders, or anyone who wants contoured key wells without a fixed width, it's the one to buy now that the Advantage2 is winding down.
Good: fully separate halves for any shoulder width; three tent settings; a wireless version; a 3-year warranty. Less good: tied for the lowest price score here, from $499 at list; the same learning period as the Advantage2.

Contoured like the Advantage line but lower, 60 millimeters tall by MoErgo's measure, and wireless out of the box. The keys run in straight columns, so your fingers move up and down instead of on a diagonal. Expect a learning period.
Good: contoured and low-profile; wireless; six thumb keys per hand; open-source firmware. Less good: priced well above the category benchmark; an 18-month warranty; columns take getting used to.

The widest tenting range here, from 5 to 60 degrees on built-in legs, plus reverse tilt, so you can find your angle and keep it. The keys run in columns, so give it a learning period; Dygma's Bazecor software handles remapping.

Composite 7.3 on the DEAS (Desk Ergonomics Assessment Score). How we score
Set your chair and desk first. Elbows about level with the keyboard and hanging by your sides, shoulders relaxed.1 No keyboard fixes a desk that is too high.
Put it directly in front of you. Center the gap between the halves, or the B key, on your body, close enough that your elbows stay by your sides.1
Fold the back feet away. Use them only if they keep your wrists straight; flat, or tilted slightly away from you, is better.1,4
Set the split and tent gradually. Halves about shoulder width apart, so your wrists line up with your forearms. Start with a low tent and raise it if it feels right.
Keep the mouse close. Right beside the keyboard, as OSHA advises.5
Hover while you type. Rest the heel of your palm on the palm rest between bursts, not your wrist, and not while you type.6
Give it time. OSHA notes you may need time to get used to these keyboards,1 and in a learning-curve study, typists quickly regained the speed they lost on a split and a contoured keyboard.7
Clinical note
If your speed still hasn't come back after a few weeks, the keyboard may be wrong for your hands or your work, not the idea of a split.
Feels like
Numbness or tingling in the thumb, index and middle fingers, often at night or after a long typing day.
What helps
Keep the wrists straight: feet folded, a flat or negative tilt, and hover while you type. A contoured keyboard like the Advantage360 is the top step if that isn't enough.
Feels like
An ache along the outer edge of the wrist, worse after long typing.
What helps
A split. Even a gentle one, like the K860, lets your wrists line up with your forearms.
Feels like
Rounded shoulders and a knot between the shoulder blades by the afternoon.
What helps
Pull the keyboard close and set separate halves, like the C989M's, to your shoulder width.
Work up a ladder, gentlest first: your own keyboard with a palm support, a basic ergonomic keyboard, a wave, a split like the K860, then an advanced split, with fully separate or contoured halves, like the C989M or the Advantage360. Higher steps straighten your wrists more and take longer to learn. The assessment picks your starting step from how much, and how often, your wrists and elbows hurt.
One sized to your frame. A narrower keyboard lets the mouse sit closer to your body, and OSHA's guidance is to keep the mouse close to the keyboard.5 The assessment's rule: compact under 5'6", tenkeyless (no number pad) from 5'6" to 6'2", and full size from 6'3".
There's a learning period, and OSHA says to expect one.1 It's shorter than most people fear: in a learning-curve study of 16 typists, the speed they lost on a fixed split keyboard and on a contoured split one came back quickly.7 In my experience, keys in columns, like the Glove80's, take longer than a standard layout that's simply split.
No. The shape is what straightens your wrists; switch type is preference. If your fingers tire, a lighter switch can feel easier: the Advantage2 uses 45-gram switches, and the mWave comes with 45 or 55.
It lowers the strain, but nobody can promise prevention. OSHA's own summary is that these keyboards help keep wrists neutral, but the research doesn't show they prevent discomfort or injury.1 Setup matters as much as shape: wrists straight, elbows by your sides, the mouse close.
Forty-three more are in the ranking. Worth a look: the InCase Ergonomic Keyboard (7.3), a compact split with a palm rest; the Matias Ergo Pro, the Ultimate Hacking Keyboard and the Dygma Raise (all 7.2); and the Kinesis Freestyle2 (7.1).
The Desk Ergonomics Assessment Score, Desk Doctor's product rating out of 10. Every product is scored on eleven dimensions in three layers: clinical performance, product quality and value. For keyboards, the category-specific part is wrist neutral and key actuation: whether the shape keeps your wrists straight (split, tented and negative-tilt designs score higher), and whether the keys take a light press.
