I am looking for an everyday, lightweight and easy to fold stroller for my 2 years old son (13 kgs).
Basically for schools run and shopping.
Not sure if this is the right one.
Thank you for your help.
I will probably disappoint you now but no, I would not suggest the Cosatto Woosh2 for what you describe, mainly because of the seat size that will be way too small for a two-years-old. This is a short-backrest, slanted seat with an even shorter leg rest and your son will be uncomfortably cramped inside. Not even talking about it being ultra-compact stroller, which is not meant for everyday use - read more here...
If I should give you some advice, go for something at least a bit larger, something mid-size, lightweight to give your kid some space and comfort, which will also help you with the push which will be much, MUCH more comfortable. From Baby Jogger City Mini2, Babystyle Oyster Zero or Valco Snap; through smaller TFK Dot2 or Baby Jogger City Mini Zip to, from the smaller ultracompact strollers, ABC Design Ping 2 or Joolz Aer with at least higher seatbacks, do think about seat size, wheel size and stroller's suspension to make your life easier, not harder.
