2007 sienna, third row: vivo, rfing radian, turbobooster.
The turbobooster is very difficult to buckle, but can be done. A better fit is:
vivo, rfing radian, fisher price booster on less than the widest setting.

Passenger outboard: RF Radian lap/shoulder
Middle: RF MA lap
Driver outboard: FF Frontier latch

RFing true fit, FFing radian, RFing true fit. Installed the the radian with a locking clip, I can't figure out how to get the locking latch plates to work! Then removed it, and installed both TFs and then put the radian back in. They are all independently tight!

I wish I lived in America - there are just no big cars in the UK!

And just as I have been doing so much research into this I thought I would share my 2 cents :)

We have 3 kids under 3 yrs, plus a dog :eek:
=> 3x three FULL size (Brittax Evolva 1-2-3's) child seats in a row
=> Space for our buggy and our dog...
=>Also we wanted something that drives most like a car and didn’t completely look like a minibus :)

So after taking our 3 seats to every car dealership in London - the ONLY cars that fit were ones with 3x individual back seats:

:thumbsdown: No SUVs fit - just too narrow
:thumbsdown: No sedans/estates fit (not even Mondeo or A4 estate), and very few 4x4s fit - even if the car was wide enough, the middle child seat covered the seatbelt buckles and so wouldn’t sit right
:thumbsdown: Most 7 seaters went out the window, as the rear seats were useless! a) you have to sacrifice the boot - when do we not take a buggy?; and b) having a ZERO rear crush zone – those passengers were killed in crash tests!

Thus it has come down to:

:thumbsup:Honda FR-V (sorry the Fiat Multipla is just to wierd looking)
Pros – 6x seats (3x isofix) and a boot! Nice drive, feels like a car
Cons – Expensive for what it is, as Honda don’t make many, so charge the earth for the ones they do :(

:thumbsup:Land Rover Discovery 3
Pros – 7x seats but the boot is big enough to have 1 rear seat up and still fit the buggy - and it has 4x4 build safety :whistle:
Cons – It’s a 4x4, so running costs are higher, and you’re really just in a cooler looking bus

:thumbsup:Nissan Pathfinder
Pros/Cons – as the Discovery above

:thumbsup:MultiMac – 3 to 4 seat child seat system
Pros – fits most vehicles and the cheapest option, as you don’t have to trade your car in.
Cons – Need to find someone who has one to see what its like – and it’s not a car

Lastly I found a useful tool to use as a rough car guide

Hope that helps!

3 across in a 2006 subaru impreza.

Blvd RF behind drivers seat, seat belt
GN middle, seat belt
FF radian behind passenger seat, seat belt.

Checked by Wendy! :)

Next mission is to purchase another radian to be able to do 2 RF as I would prefer two of the kiddos I watch to be RF if at all possible.

2003 Nissan Sentra :eek::eek::eek:

Passenger side: RF Safety 1st Uptown (needs a rolled towel to install tightly), seatbelt
Center: Ride Safer Travel Vest (with lap/shoulder belt, so didn't need tether)
Driver's side: FF Radian, with seatbelt and top tether

Not tech-checked.

OOOOh, my, that Radian was a difficult install. Needed three full twists of the buckle stalk and a lot of muscle power to tighten the belt. And I'm a very experienced Radian installer. Would be easier if you had someone to help.

I put the baby in the Uptown first when loading, then had the child in the RSTV get in, fastened her, then put the last child in the Radian.

There was barely room for my very skinny (like, barely fits the RSTV) 5 year old in the center, there's no way any but the skinniest of child riders, and adult passenger, or another restraint could fit there (except maybe a baseless BabyTrend. Maybe.) If she gets much bigger I'll have to get another RSTV for the child in the Radian as well to be able to fit them all in that car. She was using the sides of the Uptown and Radian as arm rests because otherwise they squished her elbows.

2009 GMC Sierra 1500 crew cab SL

passenger outboard: RFg MA
center: FFg RN
driver outboard: FFg GN (ETA: 100% on seat, but just barely).

All installed via belts. TTs in all three positions, headrests only in the 2 outboard positions. I wasn't trying super-hard to do three across and I'm reasonably confident I could have made it work installing the 2 outboard seats via LATCH. I didn't try a FFg MA in the mix, but I'm also pretty sure that would work with the RN in the middle. There is sooooo much room back there, LOL.

I'm not a tech, though I'd like to play one in the movies some day. ;)
