That is the one I was leaning to, but in white.

Note: I had a broken leg that couldn't bear weight, but no problems
with my equilibrium.

That stool looks fairly stable.

It is stable. Of course it may depend on who is to use it. I'm 5'9" and
~200 lbs grin

The specs give a 250 lb. capacity. Must be a safety factor in there too.
My wife uses a similr one with no problem and the height is adjustable.
