The side bolsters of your chair press into your hips, or the armrests stop you sitting square, and every roundup you read ranks chairs on lumbar support instead of the one number that would answer your question.
Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
The HON Ignition 2.0 Big and Tall is the pick on published seat width: 23 inches of pan, rated to 450 pounds, with a 24.75-inch back. The specification to shop on is seat width measured across the pan, and the second thing to check is whether the armrests sit outside your hips rather than on them.

Seat width is the number, and most listings hide it
A chair that is too narrow across the pan does not feel narrow. It feels like pressure at the sides of your hips, numbness down the outside of a thigh after an hour, or an unexplained need to sit slightly twisted. The cause is that your hips are being supported by the raised edges of the pan rather than by its flat middle, and raised edges concentrate load exactly where you do not want it.
The specification that answers it is seat width, measured across the pan. It is published far less often than seat height, and when it is published it is sometimes the width of the whole chair including armrests - which is a different and much larger number. Our seat width guide covers how to measure your own hip width and how to read a listing that gives you the wrong figure.

Notice what is absent: Herman Miller publishes no seat width for the Aeron and Steelcase publishes none for the Series 1, so neither appears above. Both are good chairs and both are recommended elsewhere on this site - they simply cannot be ranked on the number this page is about, and we are not going to estimate it from a product photograph.
Width is not capacity, and capacity is not width
These two specifications get conflated constantly and they answer different questions. Weight capacity is a structural rating - what the base, gas lift and frame are certified to carry. Seat width is a dimension - how much pan there is to sit on. The table above makes the mismatch obvious: the Branch publishes the second-widest seat on this page with the lowest capacity on it, and the HON publishes 450 pounds with two inches less width than the Hbada.
So decide which problem you actually have. If the chair creaks, sags or the gas lift sinks, that is a capacity question and chairs rated to 400 pounds and above is the page. If the chair feels like it is pinching at the sides, that is width, and this page is the one. If both, the HON is the only pick here that answers both at once.
The armrest trap
Two things to check before you order
Measure your own hip width sitting down, not standing. Sit on a firm flat surface and measure across the widest part of your hips and thighs where they contact it. Add about an inch each side so you are not pressing the bolsters. That is your target pan width, and it is usually larger than people guess.
Check the pan depth separately. Width and depth are independent, and a wide pan that is also long will put its front edge into the back of your knees. The Embody is the only pick here that publishes depth adjustment, at 15 to 18 inches. The seat depth guide has the arithmetic, and chairs with adjustable seat depth lists every option we can source a figure for.
If the pressure is pain rather than fit
Worth separating. Edge pressure on a too-narrow pan is a fit problem and a wider chair resolves it. Pain in the hip joint that stiffens through the day is a hip-angle problem, and the answer there is seat height and recline rather than width - best office chairs for hip pain and back and hip pain together cover it. Numbness or burning down the outside of the thigh is a third pattern again and not one to shop for; that belongs with a clinician.
The picks in full
1. Best for The widest published pan with a real capacity figure
HON Ignition 2.0 Big and Tall
Of the chairs in our registry whose makers publish a seat width, this is the most usable combination for wider hips: HON states 23 inches across the seat with an 18.74-inch pan depth, a 24.75-inch backrest and a 450-pound rating, behind the HON Full Lifetime Warranty. Published seat height is 17 to 21.5 inches. One thing to measure before ordering, because it cuts both ways: on a 23-inch seat the armrests sit further apart, which is what makes the pan usable but also means a narrower upper body may find the arms out of comfortable reach. That is a trade, not a flaw - but it is yours to make, not ours.
Who it fits
Anyone whose hips meet the side bolsters of a standard pan, and anyone who needs a 450 lb rating without a bespoke order.
Who it does not fit
Anyone under about 5 ft 5 in - the seat does not drop below 17 inches - and anyone with a narrow frame who needs the armrests closer in.
The widest seat width figure in our registry, and the only budget chair here that publishes a fit range at all: Hbada states 25.6 inches across the seat and claims the chair suits 5 ft 1 in to 6 ft 5 in, with a 330-pound rating, three-zone dynamic lumbar and 3.15 inches of backrest height adjustment. The warranty is five years on the base, gas lift and casters and three years on other components. Read the depth figure carefully, though: Hbada publishes a 1.97-inch seat depth, which is a cushion thickness rather than a pan length, so this is a chair you cannot confirm pan depth on from the spec sheet. Overall height is published as 43.7 to 51.8 inches, with no seat height from the floor.
Who it fits
Anyone who wants the widest published pan for the least money, and anyone in the middle of the height range.
Who it does not fit
Anyone over 330 lb, and anyone who needs a published pan depth or seat height before ordering - neither exists here.

3. Best for A wide seat without a big-and-tall look
Branch Ergonomic Chair
A 25-inch published seat width on a chair that is not styled as a big-and-tall model, which matters if the chair lives in a room you also relax in. Branch publishes eight points of adjustment, a removable lumbar pad and a seven-year warranty, with a 275-pound capacity. The seat height range is the limitation and it is a real one: 17 to 21 inches, so it never gets low. Anyone under roughly 5 ft 8 in will be using a footrest with this chair, and anyone over 275 pounds is outside the stated rating - which is the lowest on this page.
Who it fits
Anyone between about 5 ft 8 in and 6 ft 2 in who wants a wide pan and a chair that looks domestic.
Who it does not fit
Anyone over 275 lb, and anyone shorter than about 5 ft 8 in without a footrest.
4. Best for A wide seat that also adjusts in depth
Herman Miller Embody
The premium option, and the only pick here that lets you change pan length as well as having width to spare. Herman Miller publishes a 21.25-inch seat width with an adjustable seat depth of 15 to 18 inches, a 16 to 20.5 inch seat height, a 300-pound rating and a 12-year warranty. The seat is also pixelated rather than a single foam block, which spreads load across the pan instead of concentrating it at the edges - relevant when the complaint is pressure at the sides rather than lack of room. The honest limits: one shell size, and 300 pounds is the lowest capacity of the premium chairs on this site.
Who it fits
Anyone who needs width and depth adjustment together, and anyone whose complaint is edge pressure rather than sheer space.
Who it does not fit
Anyone over 300 lb, and anyone needing more than 21.25 inches across the pan - two chairs above publish more.

The HON Ignition 2.0 Big and Tall, on published figures: a 23-inch seat width with an 18.74-inch pan and a 450-pound rating, behind the HON Full Lifetime Warranty. If you want a wider pan for less money, Hbada publishes 25.6 inches on the E3 Pro at a 330-pound rating.
How wide should an office chair seat be?+
Measure across the widest part of your hips and thighs while seated on a firm flat surface, then add roughly an inch each side so you are not resting on the raised edges of the pan. Most standard task chairs publish between 19 and 21 inches, which is why wider sitters run out of room on chairs that are otherwise well specified.
Is a wide seat the same as a big and tall chair?+
No. Big-and-tall normally refers to weight capacity and frame strength; seat width is a separate dimension and the two do not track each other. The Branch Ergonomic Chair publishes a 25-inch seat with a 275-pound rating; the HON publishes 23 inches with 450 pounds. Work out which of the two you actually need.
Why do my hips hurt in a chair that is wide enough?+
Width is only one of three fit numbers. If the pan is too long for your thigh you will slide forward or slump; if the seat is too high your legs hang and your pelvis tips back, closing the hip angle. Both produce hip discomfort in a chair that has plenty of room across it.
Do armrests get in the way on a wide chair?+
They can, and it is the most overlooked side effect of buying wide. Armrests mount to the seat frame, so a wider pan puts them further apart. If your shoulders are narrower than your hips, check that the arms adjust inward or pivot - and if they do not, plan on not using them.
