DD is 2yrs old and is 105th for height. We love our Truefit Premier. She has tons of growing room in it even though shes outgrown the tribute and scenera (both spare seats). She still has about 4.5 inches of RFing growing room and is 34lbs. Its also wider than britax and the radian so she wont be so squished when she gets even bigger. I expect she will fit in this seat til shes ready for a booster.
For a spare I found the scenera to be hair taller than the tribute and about the same in every other way. At $40 I feel we got out $ worth before she outgrew it. I intend to replace it to a FF only seat that is taller and will become a booster.
