i consider portable anything that fits in the van
recently i have improved my stools as i age and am losing
some strength and stamina.. my old stools were a mix of
fixed height and older steel spinners, plus one ancient wood Piano stool,
some were upgraded with drum throne type seats, some had steel sliders,
some had casters
this is a nice height, it's a drafting stool.. the wheelbase is small
and it's lightweight so it is easy to toss in on top of everything else..
rolls easy too, so you can kick it into the gig when your hands are full
with other stuff
and a low back version is available
i just ordered another drafting stool with a wider wheelbase for
in the studio.. it too has the footring/rest, which i think is
very handy and makes a long session more comfortable

pheumatic, so easily height adjustable, these are schock absorbing
to a degree
high end regular drum thrones are stronger, foldable, nice seats,
often pneumatic, but are shorter than drafting stools, though often
a bit higher that typical office chairs, and no casters
