I don't have the info on the bar stools that we bought, but here's some random thoughts.

There are 2 different heights for kitchen stools, we bought the 30"; the other ones are shorter (I forget the measurement, 26"(?)).

When the stools are "tucked" in at the bar, they wood gets damaged where it comes in contact with the counter top edge, from pushing in the stools too far.

We have already changed (after 2 years) the material and the foam under the material; the foam was just cheap and it was like sitting on an uncomfortable wood bench.
We also got the stools that self-spin back to face the counter after leaving the seat.
Outside of the damaged wood backs, these bar stools are holding up fairly well.
