What are the best strollers for tall children?

Heya,

It would be non-reversible, only forward facing, often three wheelers. You need to look at the backrest height especially, and then, whether there is still more space from the end of the seat back to where the canopy is.

Ultimately, look at strollers like the Baby Jogger City Mini GT2 / Baby Jogger City Elite 2, BOB three wheelers, Britax B-Motion Plus, or Valco Trend which are some of the most spacious ones.
