Successful Three Across thread


Senior Community Member
Since doing 3 across seems to be a common question lately I thought I would start a thread about it.

Please post here if you have been able to successfully do 3 carseats across.

Let us know the vehicle make and year, how the carseats are installed (ie. seatbelt (and what kind) or LATCH), which way the seats are facing in the configuration (rf or ff), which seats you used and if you are not a tech if they have been checked.

If you have a picture that you would like to include that would be great, if not it's not a big deal

*Lets keep this an informative thread, if you have a question please start a new thread*

you above have me beat! lol. How do you get the MA's in tight with seat belt? Anyways,

here's my info

3rd row of 03 honda ody seat belts
Britax Parkway, MA/FPSV, Graco Turbo. I was very surprised i fit the Pkwy beside the MA but the MA base is smaller than its HIPS as as i call them. I have to buckle the older kids in as its a tight fit but works! Usually its dds friends in that row in the boosters and they LOVE to play with one of my boys :p Dd thinks she is queen in 2nd row bucket with other brother!;)

2003 Toyota Camry

Britax Parkway/FF MA/FF Radian
MA was installed with the seatbelt, Radian with LATCH.
Checked by myself, rock solid for both installed seats. PW was a pain the buckle though.


2003 Toyota Camry

Britax Parkway/Graco Safeseat/FF Marathon
Safeseat and MA both installed with seatbelts, MA pushed to the edge of seating position. Solid installs, but the Safeseat was a bit difficult to snap into the base because it was up against the front edge of the MA.

2000 VW Jetta

FF MA /RF FPSVD /FF BLVD Very Tight!! Edited to add, All were Seatbelt installs.


I've also gotten 3 across the back row of my 2005 Toyota Sienna

FF FPSVD/ FF FPSVD / Cosco Low Back Booster (Tried a Graco, but it was too tight.) I don't have pictures.

And I don't think there is one 3 across you couldn't get in the middle row of the Sienna. Well maybe 3 Regents, but you could probably do that as well.
