Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
There are two completely different products sold as mesh chairs. A tensioned mesh seat suspended in a frame deflects under you and breathes. A mesh fabric stretched over a foam pad is a foam chair with a breathable cover. The first is the reason to buy mesh; the second is not.

Which one is 'a mesh chair'
This one
Sold as one, functionally not
A mesh back over a foam seat is the commonest configuration in the budget tier and it is perfectly fine - the back is where most heat builds anyway. Just know that is what you are buying, and do not pay a premium for mesh you are not getting.
What mesh is actually good at
Heat. The clearest benefit and the easiest to predict. If you finish the day with a damp shirt back, mesh will change that.
Pressure over long durations. A suspension seat keeps deflecting where foam compresses and then presents a fixed surface. For an eight-hour day that is a real difference, and it is why mesh keeps appearing on our long hours page.
Front-edge pressure. A tensioned seat gives at the front edge rather than presenting a firm lip against the back of the thigh, which matters for sciatica.
What mesh is bad at
Cushioning. There is none. If you want to sink into a chair, this is the wrong category and no amount of persuasion changes that.
Tailbone sensitivity. A firm tensioned surface concentrates load through the bony contact points for some people. Others find the deflection helps. It genuinely splits both ways - see the coccyx page.
Cold rooms. The breathability works in both directions.
Edge comfort in cheap implementations. A poorly engineered mesh seat has a hard frame just under the fabric at the front edge, which is worse than a foam pan. This is where the premium chairs earn their money.
How to tell which one a listing is selling
The listing will not say. What to look for instead:
Photographs of the underside of the seat. A suspension seat shows a frame with fabric stretched across it. A foam seat shows a molded pad.
The word "suspension" or "tensioned". Brands that have it usually say it, because it costs more.
Price. Real tensioned suspension is a structural engineering problem and it is not cheap. A very inexpensive chair with a genuine suspension seat is unusual.
Whether the seat and back are described separately. "Mesh back" almost always means a foam seat.
Durability, honestly
A tensioned mesh seat has a real failure mode that upholstery does not: the fabric can stretch or, on a poorly made chair, tear at the frame. This is what a long warranty is for. Herman Miller warranties the Aeron for 12 years on a three-shift basis, which is the manufacturer putting a number on it. A budget mesh chair with a three-year warranty is telling you something different, and both are useful information.
This is the chair the whole category is imitating, and the reason is that both the seat and the back are genuine tensioned suspension rather than fabric over foam. The practical consequences are that the seat keeps deflecting under you rather than compressing to a final shape, and that heat and moisture pass through rather than building up - which is the actual reason to buy mesh, and which most mesh chairs do not deliver. Three shell sizes let you get the pan length right, and the C is warrantied to 400 pounds.
Who it fits
Anyone who overheats in a padded chair, and anyone doing long days in a warm room.
Who it does not fit
Anyone who wants cushioning. Suspension mesh is firm, unpadded and unapologetic about it, and a real minority of people simply do not get on with it.

The Embody is not a tensioned mesh chair in the Aeron sense - the seat is a layered construction designed to flex in sections while still allowing airflow, which is a middle position between suspension and foam. If the Aeron's unpadded firmness is the objection but a foam pan runs too hot, this is the compromise. Herman Miller publishes a 16 to 20.5 inch seat height, a 15 to 18 inch adjustable pan, a 300-pound capacity and a 12-year warranty.
Who it fits
Anyone who wants airflow without a completely unpadded seat.
Who it does not fit
Anyone over 300 lb, and anyone expecting true suspension-mesh coolness - this breathes better than foam and not as well as an Aeron.

Lumbar

Sihoo publishes mesh on both the back and the seat here, which is less common in the budget tier than the listings suggest - most budget mesh chairs are mesh-backed with a foam seat. Combined with a published 18.11-inch pan with depth adjustment and a self-adapting lumbar, it is the most functional budget mesh chair in our registry. The three-year warranty is the honest ceiling of what a chair at this price promises.
Who it fits
Anyone who wants an actual mesh seat rather than a mesh back and a foam cushion, on a budget.
Who it does not fit
Anyone who needs a published seat height, and anyone expecting Aeron-grade suspension - the tension and frame engineering are not comparable.
Sihoo describes the M57's seat as a PE polyester mesh, which puts it in the genuinely-breathable category rather than the mesh-look-fabric category, at the lowest price in our registry. Published seat depth is 18.11 inches and seat width 20.08 inches, with a 330-pound rating, a three-year warranty and 3D armrests. What you do not get is a seat depth slider or a published seat height, both of which matter more than the mesh does.
Who it fits
Anyone replacing a non-breathable chair on the tightest budget.
Who it does not fit
Anyone doing eight-hour days five days a week who expects it to last, and anyone who needs a confirmed seat height.
We are including this to make an argument: mesh is a solution to heat and to pressure distribution, and if neither is your problem, an upholstered chair with better adjustment is the better purchase. The Leap v2 is the most adjustable chair in our registry - sliding lumbar with a firmness dial, five tilt positions, 4D arms with published ranges - and it is upholstered. If you are shopping mesh because everyone else is, this is the alternative worth considering.
Who it fits
Anyone who does not actually overheat and has been assuming mesh is automatically better.
Who it does not fit
Anyone who genuinely runs hot - an upholstered pan holds heat and no amount of adjustment changes that.

For heat and for pressure over a long day, yes. For cushioning, no. And a lot of chairs sold as mesh are a foam seat with a breathable cover, which gets you very little of the benefit.
Do mesh chairs sag over time?+
A tensioned mesh seat can stretch, which is a real failure mode that upholstery does not have. It is also what the warranty is for - Herman Miller covers the Aeron for 12 years on a three-shift basis, and a three-year budget warranty tells you the maker expects less.
Is a mesh seat bad for your tailbone?+
It splits both ways. Some people find the continuous deflection spreads pressure and helps; others find a firm tensioned surface concentrates load through the bony points and makes it worse. If you have an acutely sore coccyx, try before buying.
How do I tell if a chair has a real mesh seat?+
Look for a photograph of the seat from underneath. A suspension seat shows fabric stretched across a frame; a foam seat shows a molded pad. Listings rarely say outright.
