I am trying to pick out a higher weight Britax for my DD. Any opinions on Waverly vs Sophia? I keep seeing multiple places online about the Paisley seat falling apart at the seams and needing to get replaced, and am wondering if anyone else has seen similar problems with either of these. Right now we are using two Boulevard 65s, a Riviera and a Shannon, with a Huntington back up cover. They are all different fabrics, though I like the Riviera fabric best of all. Does anyone know if the Sophia fabric is unlike any of these? It looks more nylon-ish. Or what the waverly cover feels like? Also, we live in Pensacola, FL so the heat factor is something to think about too. Though I always use our autostart, so it is never *too* hot in there.
