The narrowest harnessing seat on the market are the Radian's. I have seen 3 across in an Accord (I don't recall the seats), but there were 2 RFing and 1 in the center FFing. If you can measure the entire backseat of your vehicle, you can get an idea of what seats would fit likely. You could also head to a carseat tech with all your seats and have them configure and puzzle them in.

As long as the seats are installed independently, not relying on the seat next to them to be in there tight, then you will have a great fit.

	Forward Facing Car Seats A forward-facing car seat is one in which the child sits facing the front of the car. The seat should be installed in the back seat of your vehicle. Most forward-facing only seats are for children above 20 pounds.

	Rear Facing Car Seats A rear-facing seat is one in which the infant faces the back of the car. Always install a rear-facing seat in the back seat of your car. This is the safest position for an infant. NEVER place a rear-facing seat in the front seat of a vehicle with passenger airbags.

	Sunshine Kids Radian 80 or 65 - Click for more info If "the Sunshine Kid's Radian 80 convertible car seat is (probably) the only car seat you will ever need," the "probably" part of this statement comes into play when you directly compare the Radian 80 with the Britax Regent. While the Radian 80 has a very high weight capacity, the seat width is only 10" vs. the Regent's 14" seat. The Britax Regent may be a bit wider, but it is very bulky, is only forward facing, and does not fold like the Radian 80. Because the Radian 80 is so narrow, you can potentially put three of them side by side in the back seat. Three Regents side by side? Impossible.
