Is the 94cm seat length when the seat is reclined? My 89cm 2-year-old still regularly naps out and about in the pushchair and is currently having to scrunch up on his side to avoid hanging over the ends! Thanks
The seat surface length should be approximately that, yes. However, the proportions are more important and in each case work out differently - e.g., the leg rest on this one is quite short, so your son's feet will pretty surely protrude rather soon (I mean, they already are protruding, and there's probably a bit space over his head, I assume, which is the rest of the seat's length). That leg rest shortness is rather normal, but of course there are also strollers with different proportions.
In general, this is not a crazy long seat, though the larger your kid will be, the more he will have to have his legs bent when truly sleeping in a pushchair.
