see thread with pics here

Unfortunately I tried this with 2MAs and 1BV (DC replaced with BV by Britax) and I could not get a good fit. It must be due to them all having the LATCH bars. The DC doesn't have LATCH bars which is why I was able to get the 3 of them to fit nice and snug. I think the absence of the LATCH bars just gave a smidgen of extra room. Amazing how that one difference made such a HUGE difference.

I would monopolize the thread if I tried to list ALL the 3 acrosses I've done in the past 10 years, LOL.

So I'll just post what I've learned doing 3 across.

1. don't assume.

A big car seat may fit in a 3 across in a small car. Even in a space where a smaller seat did not fit.

A combination of seats that seems impossible may work if you change what goes where. Or what child uses which seat.

Driver and passenger outboard positions are not necessarily identical.

2. Don't be afraid to try something someone else found impossible.

3. Don't measure. The numbers NEVER add up to enough space, but that doesn't mean squat.

4. You may end up with a car seat brand you said you would never buy. (I may have to buy another d@mn Radian in the near future)

5. Don't attempt a 3 across when you are really hungry/tired/annoyed with the world. You'll end up throwing something expensive down on the driveway in disgust.

6. Do keep your sense of humor when the cop stops to ask you what you are doing in your bathrobe throwing stuff around in the driveway at 2 AM.

7.Remember that new seats are almost always cheaper than new cars. Practice saying this in the mirror before breaking the news to your SO.

8. Find a car seat buddy to play 3 across with. ( JULIE!!) Make sure to have lots of ice cream and root beer on-hand to see you through it.

Julie, may I use this at my meeting next week? It's wonderful and SO TRUE!

My three across scenerios, obviously all with belts:

1997 Intrepid:
Every combination that I tried (I can't even remember them all), RFing or FFing, of Decathlon, FPSVD, Snugride, older Triumph, or Touriva. Locking clips (or the lock-offs) were required to keep my belts tight, even with the flip the latchplate trick, for all of the installs I tried. The Snugride is a little tricky to get into its base when installed passenger side next to a FFing Decathlon.

The Graco Nautilus, while it shockingly has a belt path that holds the belt at the correct angle so the locking mechanism actually works, will definitely NOT fit outboard next to a RFing Decathlon/FPSVD, that arrangement doesn't even come close to working.

1998 2 door Chevy Cavalier
I've never actually put 3 across in this car, but I was able to install a RFing Touriva passenger outboard with a FFing FPSVD center. There was room for another narrow seat like the Touriva or a narrow booster driver's side outboard.

Not too hard. All use center seatbelt, most outboard installations use LATCH.

RFing Britax/FFing Britax, FFing RN, RFing Britax/Combi Conection/Parkway/Evenflo Chase
(The FFing RN with seatbelt is not for the faint of heart!)

Really, most anything would fit three across, although you'd have to be creative with a Regent :)

I got 3 across in a 2001 Pontiac Aztek.
Evenflo embrace, LATCH, Passenger side outboard
Sunshine Kids Radian, lap belt, centre, FF
Cosco Alpha Omega Elite, LATCH, RF or FF, Driver's side outboard.
Not checked by a tech (except online with pictures :) )

Note: in the pictures, both RF seats are braced against the front seats, which they shouldn't be. They need 1" clearance. I don't have the heart to redo this in the middle of winter so it will be warm weather before I can retake the pictures.

Would it not work better having MA/Radian/Parkway, then the buckle is on for the parkway is between that and the radian, and it is low enough down? Just a thought.
It probably would work better in the manner you described. I actually just tried it out for fun sice I had purchased a Radian for our other car (incompatible, btw). I don't have my hands a RN at present to try it out. I think when the baby comes I might try a RN FF in the middle for my then 3 yr old, and a snugride outboard for the baby. I will miss my MA though, it's my fave seat ever.

If she doesn't have LATCH in the centre, then the RN is a PITB to install FF with the seatbelt. That may be why it's outboard.
Once you figure out the tricks it really isnt' all that hard. I have installed the Radian FF with a seatbelt several times and don't have problems with it.
