Well, it seems to fit that seat.
But I don't want to be the final word.
I could not figure out latch (that's sad but it was a bit unintuitive).
I used seatbelt, which I think was the better option as it was easier to get it tight for me. 9 months pregnant install...
The fabric was a little darker than the picture, I think, so that's good for dirt. I think it's washable, too.
I installed it for the almost 2 YO. She will have to CLIMB to get into it, that's for sure. But it's so deep that once she's in...she can't squirm out while I buckle, lol.
Overall I am happy because I think she can now RF for a LONG time. She had very little growing room by height in the Advocate and she's still technically 1! (And had no leg room at ALL and would kick her brother).
