Your shoulders ache by mid-afternoon, the armrests on your chair do not adjust, and you cannot work out whether you should be using them, losing them, or buying a chair with better ones.
Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
Yes, if they adjust to the right height - resting your forearms takes the weight of your arms off the muscles across the top of your back. No, if they are fixed at the wrong height, because then they hold your shoulders up all day. Badly set armrests are worse than no armrests, and that is the part nobody says.

What an armrest is actually for
Your arms weigh something - enough that holding them out in front of you for eight hours is real work. When they are unsupported, that weight is carried by the muscles across the tops of your shoulders and between your shoulder blades. That load is felt in the neck and the upper back, not in the arms, which is why people rarely connect the two.
An armrest at the right height removes that load. The right height is the one where your forearms rest on the pads with your shoulders relaxed and dropped, your elbows at roughly 90 degrees, and no upward pressure. That is it - one job, one criterion.
Why the wrong height is worse than nothing
This is the part that gets left out. An armrest set too high does not simply fail to help - it actively holds your shoulders up, because you rest your arms on it and your shoulders follow. Now the muscles across the top of your back are working to maintain a shrug for the whole day, which is a bigger load than carrying the weight of your arms was.
Set too low, the arms do nothing at all and you lean sideways onto one of them, which introduces an asymmetry you will not notice until the week after.
Armrest height, and what each setting does
Setting
What happens
What you feel, and when
Too high
Shoulders are held up; the trapezius works all day to maintain a shrug
Ache across the tops of the shoulders and into the neck, worst by mid-afternoon
Correct
Forearms supported, shoulders relaxed down, elbows near 90 degrees
Nothing - which is the goal
Too low
Arms are effectively unsupported, or you lean onto one side
Ache between the shoulder blades, often one-sided
Too far apart
Elbows have to reach outward, so the shoulders abduct and stay there
Ache across the upper back, and a sense the chair is too big
None at all
Arms carried by the shoulders, but symmetrically and with no forced position
Mild upper back fatigue - genuinely better than any of the wrong settings above
Read the last row carefully. No armrests is the fourth-best option on that table, ahead of three of the five settings people actually use. That is the real answer to the question in the title.
The thirty-second check
Set your seat height first, from your legs and your desk - arm height is measured from a seat that has to be right already.
Sit normally and let your arms hang straight down. Let your shoulders drop as far as they will go.
Bend your elbows to about 90 degrees without lifting your shoulders. Note where your forearms are.
That is the armrest height. If the pads are above it, lower them. If they will not go that low, take them off or stop using them.
Who genuinely does not want armrests
Anyone who pulls up to a desk with a fixed apron. If the arms stop the chair getting close, you end up reaching for the keyboard - which is worse than the problem the arms were solving.
Anyone working at a dining table. Table aprons and the underside of tabletops are lower than desks, and armrests collide with them constantly. Best chair for lower back pain at home deals with that situation properly.
Anyone whose hips need a wide pan and whose shoulders do not. The arms come out with the seat, and you cannot adjust that away on most chairs - chairs for wide hips has the detail.
Anyone on a kneeling chair or a saddle stool. Neither has them, by design, because the sitting position is different.
What to look for on a spec sheet
Almost nobody publishes an armrest height range, which makes this hard to shop on. Of our whole registry, Steelcase is the only maker publishing one: 7 to 11 inches for the Leap v2. Everyone else lists "adjustable armrests" or a count of adjustment dimensions without saying what the range is, and a 2D or 4D arm with an inch of height travel is not the same product as one with four.
So in practice: look for height adjustment named explicitly, prefer a published range over a dimension count, and check the return window - because this is a specification you can only verify by sitting in the chair. We rank on figures that exist rather than describing adjustment we cannot source, which is the standard set out in how we pick.
1. Best for The only published armrest range in our registry
Steelcase Leap v2
Four inches of published height travel, and the only stated armrest range we can source for any chair on this site - which tells you how rarely makers treat this specification as worth printing. That matters because armrest height is the number most directly tied to shoulder and upper back load: too high and your shoulders are held up all day, too low and your arms hang. Steelcase also publishes a 25-inch backrest, a height-adjustable lumbar with a separate firmness dial, a 16 to 20.5 inch seat height, a 400-pound rating and a 12-year multi-shift warranty.
Who it fits
Anyone whose shoulders or upper back ache during the working day, and anyone who has never been able to get armrests right.
Who it does not fit
Anyone under about 5 ft 1 in, and anyone with long thighs - the 15.75 in pan is fixed and short.

Branch publishes eight points of adjustment on this chair, which puts armrest adjustment within reach of a normal budget - and adjustability is the entire question on this page. It also publishes a 25-inch seat width, a removable lumbar pad, a 275-pound capacity and a seven-year warranty. Two things to weigh: the 25-inch seat puts the arms further apart than a standard pan does, so check your forearms reach them comfortably, and the seat height range of 17 to 21 inches never gets low, which matters because arm height is measured from a seat whose own height has to be right first.
Who it fits
Anyone between about 5 ft 8 in and 6 ft 2 in who wants arm adjustment without premium pricing.
Who it does not fit
Anyone over 275 lb, and anyone under about 5 ft 8 in without a footrest.
3. Best for A wide frame where arm position needs checking
HON Ignition 2.0 Big and Tall
On this page because it illustrates the trade-off the rest of the internet skips. HON publishes a 23-inch seat width with an 18.74-inch pan, a 24.75-inch backrest and a 450-pound rating behind the HON Full Lifetime Warranty - a genuinely useful specification set for a larger sitter. But armrests mount to the seat frame, so a 23-inch pan puts them further apart than a 19-inch one. If your hips need the width and your shoulders do not, the arms end up outside where your elbows want to be, and reaching out to them loads exactly the muscles this page is about. Published seat height is 17 to 21.5 inches.
Who it fits
Larger and broader sitters whose elbows genuinely reach a wide arm position.
Who it does not fit
Anyone with a narrow upper body, and anyone under about 5 ft 5 in.
Only if they adjust to the right height. Correctly set, they take the weight of your arms off the muscles across your upper back. Fixed at the wrong height, they hold your shoulders up all day, which is worse than having none at all - so a chair with non-adjustable arms is often better used with the arms removed.
How high should armrests be?+
High enough that your forearms rest on them with your shoulders relaxed and dropped and your elbows at roughly 90 degrees, and no higher. Set your seat height first, because armrest height is measured from a seat position that has to be correct already.
Are armrests bad for your shoulders?+
Badly set ones are. An armrest above your relaxed forearm height means you rest on it and your shoulders follow, so the muscles across the top of your back hold a shrug for the whole day. That is a common and completely avoidable cause of afternoon shoulder ache.
Should I remove my chair's armrests?+
If they do not adjust in height and they sit above your relaxed forearm level, yes - most unbolt in a few minutes. If removal is not possible, stop resting on them and either let your arms hang or rest your forearms on the desk edge instead.
What armrest range should I look for when buying?+
A published height range, which is rarer than it should be. Steelcase publishes 7 to 11 inches for the Leap v2 and it is the only stated range in our registry. A "4D armrest" with an inch of height travel is not equivalent, so prefer a number over a dimension count.
