Sturdy lightweight 2 wheel trolley?

[MooMa83]

...needed for mum in her 80's. She will need to lift it on/off buses and it does need to be able to hold quite a bit of shopping. She also walks with a stick. The argos ones look OK but mixed reviews. Thanks for any recommendations 😊

Have you got a disability aid shop anywhere near you? It's the sort of thing she is best seeing in the flesh before she buys.
