This is my 6 year old. She has outgrown the BLVD and has 2 or 3 clicks left on her FR 85.
I put my 8 year old in it and she fits as well. She's right at the 2nd to top harness slot but she wouldn't let me take a picture.
Caleb (4 1/2) fits on the 3rd to top slot setting.
If this installs well in the middle of the suburban, it might be an option when CJ outgrows his BLVD. Even though I hate continuous harnesses and how close Evenflo typically has their shoulder straps. I didn't have time to move the straps up to fit the kids because they were going nuts.
WTG for making a harnessed seat with super high straps that isn't crazy wide and heavy and doesn't push little heads forward.
