I got the true fit for my 2nd child from when he was 4 months+ because we weren't sure anything would fit rear facing in our Buick Century. He has never really liked it. He gets overheated because of the velour material. His backside buries deep into the seat. I find that I have to keep readjusting the back padding to keep straps in place and stop hard lumps and bumps from digging into his skin. I overcame the deep seating problem by putting in our own extra padding. I also had to put in extra padding for his head. He is now comfortable enough that I won't bother getting him a different seat, but I am much more satisfied with my Britax Boulevard that we got for our 1st child. I think a 2nd Boulevard would have fit fine rear facing.
