SlimFit3™ LX 3-in-1 Car Seat (Model# 2215325)

Okay so here are the seats I have for reference: - Graco Extend2Fit 3-in-1 (RF to 50lbs) - Graco Contender Go (RF to 40lbs) - Graco SlimFit 3LX (RF to 40lbs) - Evenflo Revolve 360 Slim (RF to 50lbs) The Civic + 6’ husband is easy because I have the same lol. The Extend2Fit fits beautifully behind my husband’s driver seat—I don’t think any other seat we have would do the same. With your husband’s height, that depth measurement (not sure of the exact number off the top of my head) would be a good starting point. However, while it’s super compact from front to back, it makes up for space width wise so it’s probably not going to play nicely if you ever need to put another car seat directly next to it, even in a 3 row SUV (it would not work with the slimmest seat on the market next to it in my Pilot, for example). I’ll come back to this once my kids are in bed lol Edit—I’m back. Anywho, if you’re pretty set on capping at two kids, slim vs not slim doesn’t *really* matter (although it is nice to be able to put the two seats together and sit in an outboard seat instead of the middle when I need to be in the back for whatever reason on a road trip). If there’s any part of you that might want a third child in the future, I’d more strongly consider a seat that can go three across (16.7” is the width you’d be looking for). Even if you don’t end up installing that way, it’ll be nice to have the option to. As for rotating seats—I could take them or leave them for an suv, but every time I buckle my kids into my husband’s car I cringe because those seats don’t rotate (the Evenflo is in my vehicle—I have one seat that RF to 50lbs in each car and my kids will switch once the older one reaches the limit). My only complaint with the Revolve is that the straps tend to get twisted more easily and get uneven more often than any of my Graco seats, and the headrest could be taller since it’s an extended RF seat. Hopefully this helps give you some things to think about, but feel free to ask any other questions! ETA just for info, I replied to someone else with this so thought I’d share—the Evenflo Revolve360Slim I have is roughly 30” from the back surface of the seat it’s installed on to the back of the seat in front of it. I have it rear facing and at the appropriate recline for a child over 11lbs.
