In general, the travel strollers are on the smaller side, which is determined by their size and nature. Only a few exceptions are a bit taller, seatback-wise, one being the Butterfly, but an even sturdier, comfier model in my point of view, would be the Joolz Aer(+). You can check for that, or it's first edition, in classifieds, pre-owned, to save money - at least I would, it is a really solid stroller for what it is.
Apart from that, check perhaps the Kinderkraft Nubi 2 which is on the budget-friendly side, though a little larger when folded.
Personally, though, if you mean to use the stroller not just for traveling but also for daily use, I would go for something a little larger, with larger wheels and more space - from the Cybex Eezy S+2 to pushchairs like the Valco Snap or Oyster Zero.
