Where do I turn to for a travel stroller with a long back rest, high-ish weight capacity (22 kg, preferably 25 kg) that can do cobble stone? It doesn't have to be ultra compact/cabin sized (in which case I guess we should be looking at the Bugaboo Butterfly?) but should fold up small enough to comfortably take on a train (including carrying up and down stairs). Bonus points if it comes with a pull handle or a transport bag. I was considering the Woosh Trail, but don't know if the seat unit will do, or the Emmaljunga Kite, but am not happy with the (lack of) recline and how the backrest reclines.
We have an Angelcab U-Series (and an Emmaljunga NXT 30) for every day use so really just looking for something less bulky that folds away easily on long distance trains or in smaller hotel rooms but can still tackle typical German old-town cobble stone streets. The stroller will mainly be used for our now 6 months old but should hopefully also fit our tall 3 year old (I don't mind carrying little one but can no longer carry older brother for longer distances when he tires).
I'd really appreciate your help!
