Coated upholstery
Smooth, non-permeable and still a SOFT surface — which is why the hard-surface spray that seems obviously right for it is the thing most likely to wreck it.
What not to do
Isopropyl alcohol may damage Coated upholstery
Best avoided
The available guidance advises against this.
The harm is STAINING rather than destruction of the coating. The source lists hand sanitisers among the substances that mark a coated fabric, which is a different finding from a solvent attacking a polymer.

Mild cream cleanser may damage Coated upholstery
Best avoided
The available guidance advises against this.
A hard-surface product on a soft surface. The coating is smooth enough to invite it and is not a worktop.

In detail
Vinyl, polyurethane and silicone upholstery is the material people reach for precisely because it wipes clean, and that instinct is what damages it. The trade body classifies coated fabrics as SOFT-SURFACE materials despite being smooth and non-permeable, and states that cleaners, sanitizers and disinfectants formulated for hard surfaces are not intended for soft surfaces and could damage them. The surface reads as plastic, so it gets treated like a worktop; the specification says it is not one. Two further points matter more in a house than in the hospital this was written for. Rinsing is the step that actually gets skipped — the guide observes technicians typically do not rinse these chemicals off, because protocol and time prevent it, so residue is the normal case rather than the failure case. And the substances that mark it are mostly not dirt: alongside body fluids it names moisturisers, cosmetics, suntan lotion, HAND SANITISERS, nail polish and fragrances. There is no general answer to whether a product is safe here — the guide directs the reader to the supplier's bulletin of lab-tested cleaners, which concedes that compatibility is a property of the specific coating.

“Not known” means nobody has established this, not that the material is unaffected.
Where the answer depends
Sodium hypochlorite (chlorine bleach) may damage Coated upholstery
Not established
Whether this is safe is not established by any authoritative source. That is not the same as it being safe — it means the evidence needed to answer has not been published. Do not treat this as permission to proceed.

Why
- Coated upholstery is explained by Porous and non-porous surfaces
The classification readers get wrong, and so do the products. Smooth and non-permeable is not the same thing as a hard surface.
- Coated upholstery is explained by Cleaning, sanitising and disinfecting
- Coated upholstery is explained by Rinsing and residue after disinfecting
Residue is the normal case rather than the failure case, because rinsing is the step that gets skipped.

When the obvious answer is wrong
How do I get grease off a vinyl seat without leaving a mark on it?
The coated-fabric trade body classifies vinyl, polyurethane and silicone coated fabrics as SOFT-SURFACE materials despite their being smooth and non-permeable, and states that hard-surface cleaners, sanitizers and disinfectants are not intended for soft surfaces and could damage them. It then names hand sanitisers among the substances that STAIN coated fabric. So the alcohol wipe that removes the grease is on the list of things that mark the seat, and the mark it leaves is not a soil sitting on the coating that can be wiped off again.
A different kind of treatment works: Take the soil off first with a soft-surface product rather than a hard-surface one, and treat cleaning and disinfecting as two operations rather than one. The trade body is explicit that they are not the same: a soil-removal product may not disinfect and a disinfectant may not remove soil, and the surface should be clean of soil BEFORE anything is sanitised or disinfected. Then rinse, which is the step this source says almost nobody performs — it observes that technicians typically do not rinse coated fabric, so product residue is the normal state of the surface rather than the exception. A residue film is what makes a cleaned vinyl seat feel tacky and pick up the next mark faster. None of this applies to ordinary fabric upholstery, which is a different material with different guidance.
