I searched, and can't find any threads on this seat! http://kiddyusa.com/kiddyusa-home.html car-seat.org has a handful of posts but not tons of info. I saw it on display at a local store. I wanted to try it but through a cascade of annoyances that occurred throughout the day, didn't get a chance to. But I got to pick it up and look it over. I was veeery intrigued! Sitting next to the parkway and monterey, it looked narrower at the base and the shape of it and the positioning of the sides, it looks like it would be easier to buckle next to a car seat than most high back boosters. I didn't get a chance to test that theory, however . we currently have a nautilus, which is somewhere around the *last* choice anyone would want to squeeze in a 3 across. I got to try a parkway, which was a good bit better at least. But I couldn't get that cruiserfix out of my head so I didn't buy the parkway. I went home to amazon and bought that sucker with next day shipping. I'm clinging to the hope that it will fit next to a rf radian. I'm positive it will fit better than the nautilus. Anyway, after it arrives and we try it out, I'll post my thoughts on it! :)
ETA: isn't it torture to order something on a saturday night?! UGH! I need to get my hands on that thing!
