I'm sorta like the OP. I'm not against a van, it's just that I don't want to have to buy another car if I don't have to. I just bought a
Radian 65 for my Subaru Impreza wagon for my
rear facing daughter, but because I'm 6' tall and have the driver seat pushed all the way back, the rear face doesn't work because the
Radian is SOOOO TALL. I missed that point in the research. =( This necessitates I put that chair behind the passenger side.
The
radian is indeed narrow at the base of 13", but the side bolsters are 17". And yeah, the
radians are HEAVY because of the steel inner frame; and thus SOLID. The material is plush suede and comfy padding.
But back on topic, the
radians are clearly the most narrow seats possible. But the height is REALLY TALL which makes
rear facing frustrating. My take is if you have a car big enough for
rear facing radians, you have a big car.
