My son is long, in fact so long that we should have got the regular Keyfit and not the Keyfit 30 as he'll be long out of the seat months before he hits the 30 pounds. So its time to look at convertable car seats. After much reading, the wife and I really like the Britax Boulevard. That being said it is rather large and I'm not sure, even though the Infiniti Snug Kids lists the seat in front+rear facing, if its comfortable for the front seat passengers. Does anyone on here have any experience with this model in rear facing configuration?
