http://www.specialtybaby.com/sa1stsibiboc.html My DD is 5, 37lbs, 39 inches (not sure of her torso, but I do know it's shorter than her almost 4yr old sis' and she (sis) still has room in the scenera). I drive a 2003 Chevy Astro van (it does have headrests). I want to keep her harnessed for as long as possible. I really want to get a Regent, but that may take awhile so I was thinking of this seat to hold us over for a while. I don't see her outgrowing it in height or weight anytime soon. Thanks
