Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
These two requirements genuinely conflict. Low-seat chairs tend to have short backrests with lumbar support set for a shorter torso, and the best lumbar systems sit on chairs that bottom out at 17 inches. Seat height wins: fix the feet first, then add lumbar support separately if the chair lacks it.

Why short and back pain is a harder problem than either alone
This is the section most guides skip, because it requires admitting the two shortlists do not overlap. Here are the competing requirements, stated plainly.
The requirement from the body axis
You need a chair whose minimum seat height is at or below roughly a quarter of your standing height - about 15.5 inches at 5 ft 2 in - and a seat pan under about 16 inches. The market's default minimum is 17 inches with an 18-inch pan. That eliminates most of it before you read a single feature.
The requirement from the pain axis
You need lumbar support that lands at the point where your spine actually curves inward, which on a shorter torso is lower than the position a fixed molded bump is set to. So you want an adjustable lumbar pad with enough downward travel to reach you.
Where the two conflict
The chairs with the best lumbar systems - the ones with height-adjustable pads, firmness dials and real travel - are full-size chairs designed around an average adult, and they mostly bottom out at 16 to 17 inches. The chairs that go genuinely low are either smaller shells from one manufacturer, or budget chairs with no lumbar adjustment at all.
Worse, on a short torso even an adjustable lumbar pad can run out of downward travel before it reaches your curve, because the adjustment range is calibrated for a taller back.
Which one wins, and why
Seat height wins. The reasoning is about what can be fixed afterwards:
A chair that is too high can be corrected with a footrest, but that is a second purchase and a permanent piece of clutter.
A seat pan that is too deep cannot be shortened on a chair without a depth slider.
Missing lumbar support can be added, completely and cheaply, with a strapped cushion placed exactly where you want it.
So the order is: buy for seat height and seat depth, which are structural and unfixable, and treat lumbar support as the adjustable variable. That is the opposite of how this category is normally sold, and it is the right way round.

Measure it - find the curve with your hand
There is no population table for this; yours is yours
The arithmetic and the cited anthropometric source are in the seat height guide and the seat depth guide. Take the two numbers to the comparison table above and most of the decision is already made.
Setting up whatever you end up with
Feet flat first. Drop the chair to your number. If it will not go, add a footrest - a box works while you decide.
Then depth. Two fingers between the seat edge and the back of your knee. Use the slider, or a cushion behind your back to move you forward.
Then lumbar. Find your curve with your hand. Set the pad there, or place the cushion there. Sit back against it and leave it alone for a week.
Then armrests. Shoulders relaxed and down, elbows at your sides. Short sitters most often have these too high, which shrugs the shoulders all day.
The advice above is for diffuse lower back ache that comes on through the day and eases when you stand. If your pattern is different, the priority order changes:
Pain running down one leg: the sciatica page - seat depth becomes the first priority rather than the second.
A sore point at the base of the spine: the coccyx page - but note that a seat cushion raises you, which fights the short-sitter requirement.
Ache between the shoulder blades: the neck page - armrest height is usually the cause, and short sitters get this wrong more often than anyone.
The picks in full
1. Best for Both requirements, no compromise
Herman Miller Aeron
This is the only chair in our registry that resolves the conflict outright rather than trading one requirement against the other. The A size publishes a 14.4-inch minimum seat height with a 16-inch pan, so the fit problem is solved by the shell rather than by adjustment - and the PostureFit SL option supports the sacrum and lumbar on a back scaled to a smaller torso, so the support lands where your curve actually is. That combination is the reason this page exists and the reason the Aeron sits at the top of it.
Who it fits
Sitters roughly 4 ft 10 in to 5 ft 4 in with lower back pain, up to the A size's 300 lb rating.
Who it does not fit
Anyone who orders a B or C without checking - the fit advantage disappears entirely. Also anyone who dislikes a firm unpadded mesh seat, which is a real and common objection.
Published specifications

Lumbar

If the Aeron is out of reach or you want padding, the Leap v2 is the compromise that costs least. Its 16-inch published floor is low for a full-size chair, the 15.75-inch pan is genuinely short, and the lumbar pad slides down the backrest rather than being fixed at an average person's curve - which is the specific failure a short torso runs into. Between 5 ft 1 in and 5 ft 4 in you will want a small footrest with it, which is a fine outcome.
Who it fits
Sitters from about 5 ft 4 in up without a footrest, from about 5 ft 0 in with one.
Who it does not fit
Anyone who wants the chair alone to solve the height problem below 5 ft 4 in - a 16 in floor is low but not low enough.

Lumbar
Height-adjustable lumbar plus a lower-back firmness dial
The Embody's seat depth range starts at 15 inches, the shortest adjustable pan on this page, which matters if your thighs are short even relative to your height - a common pattern that the height-based tables cannot capture. The backfit control shapes the whole backrest rather than pushing a single pad forward, so there is no fixed bump to land in the wrong place on a shorter torso. Seat height starts at 16 inches and the warranty runs 12 years.
Who it fits
Short sitters with proportionally short thighs, who found a lumbar pad itself to be the problem.
Who it does not fit
Anyone over 300 lb, anyone under 5 ft 1 in without a footrest, and anyone hoping to size down - there is one shell only.

Lumbar
Backfit adjustment across the whole spine rather than a lumbar pad
This is the practical resolution of the conflict, and it costs less than a tank of fuel. Buy the chair for seat height and seat depth - the two things you cannot fix afterwards - and then add lumbar support at whatever height your back actually curves. A strapped cushion places support far more precisely than a fixed molded bump ever will, and for a short torso that precision is the whole point.
Who it fits
Anyone who found a chair that fits their legs but has no usable lumbar support.
Who it does not fit
Anyone whose chair is too high or too deep - a back cushion does not fix either, and on a too-deep seat it only partly helps by moving you forward.

Questions people actually ask
I am 5 foot 1 with back pain. What should I buy?+
A Herman Miller Aeron in an A size is the only chair in our registry that publishes a low enough seat - 14.4 inches - with lumbar support scaled to a shorter back. If that is out of budget, buy the lowest-seat chair you can afford, add a footrest, and put a strapped lumbar cushion at your curve. That combination costs a fraction as much and addresses both requirements.
Should I prioritize seat height or lumbar support?+
Seat height, every time. A lumbar cushion can be added to any chair for very little; a chair that will not go low enough can only be corrected with a footrest, and a seat pan that is too long cannot be corrected at all without a depth slider.
Does a lumbar cushion work as well as built-in lumbar support?+
For a short torso it is often better, because you place it exactly where your curve is rather than relying on a pad whose adjustment range was calibrated for a taller back. The downside is that unstrapped cushions migrate; a strapped one does not.
Will a footrest actually help my back?+
Yes, if your feet currently dangle. Unsupported feet tip the pelvis backward and flatten the lumbar curve, which is the mechanism behind most desk back pain. Supporting the feet removes that at source.
