The  Agriframes are lovely @BenCotto, but budget could be a consideration of course.

Good point about checking the reviews, although not infallible, they do give a general indication.

I have gap garden products obelisks and they are sturdy and good value, so I imagine the arches are too, as per @BenCotto’s recommendation. Can’t comment on other brands.
