Car seat three across

I know it's a long shot but does anyone know if it's possible to put three seats across in a 2008 Honda accord?
The seats would have to be 1 booster, 1 rear facing car seat and 1 forward facing britax marathon.

If no one knows does anyone know somewhere I can get this information?

I tried looking on car_seat.org but I could not find an answer.

Thanks!

Re: Car seat three across

I don't have a Honda accord but we have a pilot and we need to fit 3 across, so I have a convertible diono carseat, britax marathon, and a graco rear facing car seat all in a row. they fit. Im sure if the booster is on the slim side it would fit all of them.
I was having a hard time trying to find anything about 3 carseats in a row and didn't find much. but I found that the diono carseats can fit 3 across so eventually all 3 of my kids will be in a diono.

I'm sure they will. I fit 3 across in an old rav-4 and in a toyota corolla. I have a booster and 2 sunshine radians. But i have also fit a britax marithon and 2 infant seats.
