Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
Lumbar support comes in four versions and only two of them are worth paying for. What you want is a pad you can move to the height where your back actually curves, and ideally a separate control for how hard it pushes. A molded bump set to an average spine is not the same product.

The four kinds of "lumbar support"
This is the whole of the category, and the differences are larger than the brand differences:
What the phrase covers, and what each version can and cannot do
Type
What it is
What it cannot do
Molded shape
A curve pressed into the backrest. No adjustment.
Move to your curve. If it is at the wrong height for you, it always will be.
Height-adjustable pad
A pad that slides up and down the backrest.
Change how hard it pushes. And on a short torso it can run out of downward travel.
Height plus firmness
A sliding pad with a separate depth or tension control.
Very little - this is the complete version.
Whole-back system
A control that changes the curvature of the entire backrest.
Give you a targeted pressure point, which some people want.
If a listing says "ergonomic lumbar support" without saying which, assume the first one. That assumption is right far more often than not.
How to read a listing properly
The phrases that mean something, and the phrases that do not:
Means something: "height-adjustable lumbar", "lumbar depth adjustment", "lumbar firmness dial", a published range in inches or millimeters, "adjustable lumbar is an option" (annoying but honest).
Means little: "ergonomic lumbar support", "S-shaped backrest", "contoured to the spine", "dynamic lumbar" with no further description, "lumbar pillow included" (a strapped cushion, which you could buy for twenty dollars).
One more: a backrest with height adjustment is a form of lumbar adjustment, even when it is not described that way. Raising or lowering the whole back assembly moves where the molded curve contacts you, which achieves most of what a sliding pad does. The Doro C300's published 18.11 to 21.65 inch backrest lift is genuinely useful for that reason, and Hbada's 3.15 inches of backrest height adjustment is the same idea.
Where your lumbar support should sit
Find it with your hand: stand up, run your fingers down your spine, and locate the point where it curves inward most. That is usually somewhere around the level of your navel at the front, and it varies by torso length. Set the pad, or place the cushion, at that point.
Two common errors:
Too high. The pad pushes your mid-back forward and arches you unnaturally. This is the usual outcome for short-torso sitters on chairs with limited downward travel.
Too low. The pad pushes on the pelvis rather than the spine, tipping you forward off the seat. This is the usual outcome for tall sitters.
Do you actually need lumbar support?
A fair question, and the category assumes the answer is yes. What lumbar support does is preserve the natural inward curve of the lower spine while you sit, which prevents the pelvis rolling backward and loading soft tissue. The OSHA computer workstation guidance lists backrest support for the lower back curve as a standard chair requirement, and that is the mainstream position.
But for a specific individual, there is a cheap way to find out rather than assuming: put a twenty-dollar cushion on the chair you already own and see what a week changes. If the ache eases, you need it and should buy a chair with a proper adjustable version. If nothing changes, your problem is more likely seat height, seat depth or time in one position - and a chair bought for its lumbar system would have been the wrong purchase.
The chairs that deliberately do not have a lumbar pad
The Embody is on this list without one, and that is not an oversight. There are two coherent design philosophies here:
Targeted support: push one region forward to hold the curve. Most of the market.
Distributed support: shape the whole backrest so nothing is pushing harder than anywhere else. The Embody, and to a degree the Aeron's PostureFit SL, which adds a second sacral contact rather than intensifying the lumbar one.
Neither is correct in general. If a lumbar pad has always felt like something digging into you, the second approach is worth trying, and the full comparison is in adjustable versus fixed lumbar.
Get the seat right first
Lumbar support cannot compensate for a seat that is too high or too deep. If your feet do not reach the floor, your pelvis is tipping backward regardless of what is behind your back. Run your numbers through the seat height table and the seat depth guide before spending on lumbar features.
The picks in full
1. Best for Height and firmness, separately
Steelcase Leap v2
This is the most complete lumbar system in our registry and the reason the Leap v2 leads nearly every back-pain page on this site. The pad slides up and down the backrest so you can place it at your curve rather than at an average one, and a separate dial changes how firmly it pushes. Those are two different problems - where and how hard - and almost every other chair conflates them or leaves one out entirely. Steelcase also publishes a 25-inch back height, so the support sits on a backrest tall enough to matter.
Who it fits
Anyone who can point at where their back hurts, and anyone who has found lumbar pads either too soft or too aggressive.
Who it does not fit
Anyone under about 5 ft 1 in, and anyone with long thighs - the 15.75 in pan is short.

2. Best for Support at the sacrum as well as the lumbar
Herman Miller Aeron
The Aeron offers two different back options and the distinction matters. A standard adjustable lumbar pad works like everyone else's. PostureFit SL adds a second pad lower down, supporting the sacrum - the base of the spine below the lumbar curve - on the argument that holding the pelvis upright matters as much as pushing the lumbar forward. Whether that suits you is individual, but it is a genuinely different mechanism rather than a marketing variant, and three shell sizes mean it lands in the right place.
Who it fits
Anyone whose pelvis rolls backward when they sit, and anyone at the ends of the height range who needs the shell to fit first.
Who it does not fit
Anyone who orders without checking the size chart, and anyone who dislikes an unpadded mesh seat.

The Embody rejects the lumbar-pad premise. Instead of pushing one area forward, the backfit control changes the curvature of the whole backrest so it follows your spine along its length. For a reader who has tried lumbar pads and found the concentrated pressure point to be the problem rather than the solution, this is the alternative worth knowing about. Herman Miller publishes a 12-year warranty, a 300-pound capacity and a 15 to 18 inch adjustable seat depth.
Who it fits
Anyone who finds a lumbar bump uncomfortable at exactly the level of their problem.
Who it does not fit
Anyone over 300 lb, and anyone who wants targeted pressure at one point - this deliberately does not provide it.

Lumbar
Backfit adjustment across the whole spine rather than a lumbar pad
The Doro C300 publishes a backrest that lifts through 18.11 to 21.65 inches, which is a real adjustment - moving the whole back assembly changes where the lumbar contact lands, which is most of what a sliding pad does. The dynamic lumbar then flexes with you rather than holding one fixed pressure. At a budget price with a 330-pound rating and a three-year warranty, that is a reasonable amount of genuine lumbar function.
Who it fits
Anyone on a budget who wants the support to land somewhere they choose rather than where the mold put it.
Who it does not fit
Anyone who wants to control firmness independently of position - there is no firmness dial - and anyone who needs a published seat height.
5. Best for Adding support to a chair that has none
Everlasting Comfort Lumbar Support Pillow
A strapped cushion is the most precisely placeable lumbar support available, because you decide the height rather than the adjustment range deciding for you. That matters most for short torsos, where a chair's lumbar travel frequently runs out before it reaches the right point. It also works on a dining chair, a car seat, or a fixed chair at an office you do not control. Read this as the first thing to try, not the last resort.
Who it fits
Anyone on a chair with no lumbar adjustment, and anyone testing whether lumbar support is their issue at all.
Who it does not fit
Anyone whose chair is the wrong height or depth. A back cushion does not fix either of those, and it slightly worsens a seat that is already too shallow by pushing you forward.
Published specifications
Lumbar
Fixed-contour memory foam; position set by two adjustable straps
The Steelcase Leap v2, because it separates the two controls that matter: a pad that slides to your height, and a dial that changes how hard it pushes. Almost nothing else gives you both.
Is adjustable lumbar support worth the extra money?+
If your back curves at a different height from the population average, yes - and you cannot know that without trying. A twenty-dollar strapped cushion on your current chair tells you in a week whether placement is the variable for you.
Where should lumbar support sit on my back?+
At the point where your spine curves inward most, which you can find in five seconds by running a hand down your back. Too high pushes your mid-back forward; too low pushes on your pelvis.
Can I add lumbar support to a chair that does not have it?+
Yes, completely, with a strapped cushion. For a short torso it is often better than built-in support, because you choose the exact height rather than relying on an adjustment range calibrated for a taller back.
Is dynamic lumbar support better than a fixed pad?+
"Dynamic" usually means the support flexes as you move rather than holding one fixed pressure, which is a reasonable thing to want. It is not a substitute for being able to set the height. A dynamic pad in the wrong place is still in the wrong place.
