I don’t have a potting bench, when I pot plants I generally sit on the curb of my sidewalk and pot from there. However, after really looking at them, I’m thinking it would be a nice thing to have.

Stuart at Gardening Tips N Ideas writes about potting benches:

I’ve just always assumed that if you have your garden potting shed
then a potting bench was a superfluous decoration. But the assumption
fails, of course, if you don’t have your own garden shed - and most
gardeners residing in apartments and units won’t.

So the next best thing is to perform all your potting duties in a
location that is practical and accessible. Enter stage left - the
potting bench!

I don’t have a garden potting shed, either, my garage serves that purpose. Stuart links to a DIY version of a potting bench, or you could always buy your own, the one I have pictured is one from Target.
