Lightweight pushchair recommendations for petite parent: which would you buy again?

[Shopaholic100]

Which pushchair did you buy and would you recommend it? I’m currently trying to help a friend and some of them are so heavy, she is quite petite. Obviously we will go and look instore but but would appreciate recommendations. Were there any that you really didn’t like?

Joolz Aer all the way. I'm 5ft and don't have a car so have taken it in all sorts of public transport, planes, buses, underground, up and down stairs as it folds so easily and is lightweight.
