Thanks so much for responding! She's almost 13 and half months, about 19.5lbs. Don't have her current length handy but she's currently in a chicco keyfit 30 and she has about 1.5 inches of head room left so I know I have to move to a convertible ASAP. She's generally been in the 20-25% for weight and 40-50% for length. No other seats in the back. I know that subaru discourages seats in the middle but we've had our keyfit there with no issues, so we were hoping to find a convertible that would also work there.
No problem, happy to help!
Yeah, that mention in the Subaru manual is really odd. I saw that recently and questioned it. But the consensus seems to be that it's safe if using the seat belt for install, as Subaru IS clear that borrowing of the outboard inner lower anchors isn't allowed.
So going with that, you'll want a seat that installs well with the seat belt in the center. In that case, I always prefer a seat with built in lockoffs, like your KeyFit.
Some convertibles with built in lockoffs are:
Britax Convertibles (all of the ones on the market now I do believe)
First Years True Fit
My mind is drawing a blank right now, but hopefully someone will be along with others! LOL
You can also see our list of recommended seats here:

Any of these can be installed with the seat belt. And with LATCH, because you might find that moving to an outboard position is much easier with the convertible and if that happens then installing with LATCH, if you get a good install, can be great. (You stop using car seats after a while, but continue to use the seat belts for the life of the car, so I prefer to use LATCH whenever possible!)
