I am looking for a stroller with a very tall back rest for my almost 4 years old to nap in! Easy to maneuver on walks and ideally with height adjustable handles! Thank you!
There are not too many strollers spacious and comfy enough for a 4yo to nap in, so you will need to count on a bit of compromise. My best advice here would be a Baby Jogger, either a City Mini2/City Mini GT2, or a City Elite (2) as those are truly more roomy as well as can carry a heavier load. Apart from that, check the Valco Trend or the Britax B-Motion Plus which have large seats as well.
