Truth to be told, I didn't even know this stroller exists, so no love at first sight. I bumped in it randomly by being offered to change mine for this one. The fact that I am not sorry for this change was clear after the very first walk with it 😍
Forst that got my heart was the driveability - nice push, suspension, a smooth ride even on harsh terrain... The chassis is really lightweight but very stable. Just its black color tends to scratch easily. The wheels are made of quality material - they are not too hard, but they don't take in small stones either. They are very close to air-filled tiered, comfort-wise, but without the risk of getting a puncture. The handlebar adjusts in many positions; you just need to get the knack for it to fit it to the right positions to be able to click the securing clasps in. The basket is large and very open - I usually put a blanket over what we had in it to cover it from the sight of others.
The seat unit is an ergonomically-shaped one, which is not my preference, but my daughter was OK in it and liked to sleep inside as well. The padding is very soft and comfortable. The hood can be extended, but I would make it even bigger, and the zipper is a bit stiff for me, so I kept it always open. The leg rest is adjustable and covered in black fabric that makes dirt quite visible - I was aftŕaid we'll scratch it. The size of the seat is ok; it's a medium-sized seat, I would say. My 20-month-old is tall for her age, and she's alright in there, the leg rest being put down (otherwise, her legs were dangling over the edge). There is still a bit of space over her head to grow. Internal width is also average for the type.
I take one point for the biggest downside of the Harvey - the fold with the seat only facing forward. It's not the smallest after folding either, and the shape of the folded stroller is not practical. My husband refused to load it in his car, because, as he said, it's egg-shaped, and it touches the ground with the part of the chassis between the front wheels, which is sharp and made a mark in our car boot carpet. So it damages not only our boot but also the chassis itself - since it can get scratched. If you want the folded stroller to stand completely upright, that's impossible.
