3 Across Installations: Which Car Seats Fit in a Toyota RAV4?

The Toyota RAV4 is one of the most popular small SUVs sold today in the United States. It competes directly with crossovers like the Honda CR-VJeep Patriot, Jeep Compass, Nissan Rogue, Mazda CX-5, Subaru Forester, and Ford Escape. The newest generation of the RAV4 includes a range of great safety scores in the small overlap, moderate overlap, side, and roof strength domains, as well as ESC and side airbags. The next step for Toyota will be to add front crash prevention systems now that they’ve worked out their small overlap issues with it.

Because it’s such a reliable, affordable, fuel-friendly, and attractive little SUV, it’s no surprise lots of parents would turn to it as a way of keeping their children safe. Unfortunately, due to the overlapping seat belt setup Toyota keeps building into the back seat of the Rav4, it is essentially a 5-seat vehicle capable of seating 4-persons, and has been for several years now. This is part of why it’s taken me so long to review it for 3 across compatibility; I didn’t want to take the trouble of borrowing one when I was sure of what the conclusions would be. But I’ve got a bit of free time now so let’s take a look together. Before that, however, here are some basics in car seat safety selection:

Car seat safety starts with rear-facing our little ones; it’s best for their soft spines and disproportionally large heads. I recommend you rear-face your infants, toddlers, and preschoolers for as long as possible (ideally until 4!), before forward-facing them in harnessed convertible or combination seats (ideally until 8!). Once they outgrow their harnessed seats, it’s best to keep them restrained in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). These suggestions may take a bit of extra work, but they provide a lot of extra safety.

Keeping these ideas in mind, I set to work to find which infant, convertible, combination, and booster seats would work best in 3 across combinations in the Toyota RAV4. It’s my goal to make this list the most thorough on the Internet and my hope that Toyota will soon return to a sensible back seat design for the Rav4. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

Tips and Tricks:

The current generation of the RAV4 shows a welcome return to sanity. Toyota redesigned the back seats just enough to make 3 across installations both feasible and safe, meaning it’s officially a 5 person SUV again! Dimensionally,  it’s a shade under 181 inches long, 73 inches wide, and 65.4 inches tall. As a result, you’ll be able to fit narrow seats in the 2nd row as long as you’re willing to use seat belts instead of LATCH. As is almost always the case with small SUVs (which are essentially raised versions of small cars),  front-to-back room will be limited, particularly if you’ve got taller occupants in the front row.

Guaranteed 3 across installations: None!

The current generation Toyota Rav4 continues an unfortunate step backwards in car seat compatibility, due to the ridiculously overlapping seat belts in the back seat. This was the case with the previous generation as well, and all signs point to this continuing to be a “feature” of the Rav4, despite Toyota’s continued insistence that it is a 5-person vehicle.

While overlapping seat belts in and of themselves don’t automatically exclude a vehicle from 3 across capabilities (the Highlander has overlapping belts but is still a decent 3 across vehicle, for example), when the belts overlap to a significant degree (as in the current generation Corolla, Rogue, or CX-5), 3 across becomes an impossibility for safety reasons. I’ve included 2 car seat arrangements that will work easily given the available space in the Rav4, but until Toyota corrects this, the Rav4 will remain a 2-across vehicle.

The 2007-2012 generation Toyota Rav4 began an unfortunate step backwards in car seat compatibility in this generation, due to the ridiculously overlapping seat belts in the back seat.

Tips and Tricks:

The 2007-2012 generation of the Toyota Rav4 is 181 inches long and 71 inches wide, which gives you slightly less room for 2 across than in the current generation. However, due to to the overlapping seat belt issue again, you’re still dealing with 2 across, so there’ll be room for just about whatever you’re interested in fitting, as long as you only want 2 of them.

3 Across Installations: Which Car Seats Fit a Toyota 4Runner?

The Toyota 4Runner might just be my favorite mid-sized SUV currently on the market, along with the Volvo XC90. It’s bulletproof in its reliability, has great towing and seating potential, and is also one of the safest used SUVs you can buy per driver death rates. It competes with other 3-row mid-sized SUVs like the Honda Pilot, Ford Explorer, Dodge Journey, Hyundai Santa Fe, Ford Flex, and with its stablemate the Toyota Highlander, and it’s a fan favorite among those who enjoy off-roading and exploring the glorious back country of the US.

Being such an awesome SUV, I made it my mission to figure out how well it did when it came to fitting 3 car seats across the 2nd row. The good news is that it’s a wide-enough SUV to theoretically fit 3, 4, or even 5 car seats in, presuming you buy the trim levels with the optional 3rd row seats installed. The bad news? Well, there isn’t really any; it’s a Toyota. Before we dig into the details of which seats will give you the easiest time making 3 across installations work, let’s look at which kinds of car seats should be used to keep your kids safe at various ages.

First of all, I like to begin with rear-facing, since it’s the safest position for young children. I suggest rear-facing from day one until you can’t anymore, even if that takes you through the preschool years (ideally until 4!), before forward-facing them in harnessed convertible or combination seats (ideally until 8!). Once they outgrow their harnessed seats, it’s best to keep them restrained in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). These suggestions may take a bit of extra work, but they provide a lot of extra safety.

My results of car seat puzzling in the 4Runner are below. It’s not a complete list, but as with all of my 3 across guides, it’s my goal to make it the most complete on the Internet over time, especially as I get access to more seats. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

Tips and Tricks:

The current generation of the Toyota 4Runner is 190 inches long and 76 inches wide, which means you’re going to be able to fit a lot of car seats in the 2nd row without much trouble. If you want to use the 3rd row, however, you’re going to be significantly more limited since it’s a relatively short vehicle to have 3 rows of seating. I’d only recommend having kids sit in there, although you can potentially squeeze in a couple of smaller car seats in there with a bit of practice. In the 2nd row, make use of your seat belts to get maximum side-to-side space, as usual.

Tips and Tricks:

The 2003-2009 generation of the Toyota 4Runner is 189 inches long and 74-75 inches wide, depending on whether you have a pre-2006 or 2006-and later model within this generation. Practically speaking, you’re still going to be able to fit just about every car seat from the current generation into this generation, but depending on your model year, it might be slightly to significantly more difficult to do so, especially if you’re using any of the LATCH anchors instead of seat belts for all of your seats. It’s definitely possible to get all of these seats in there, though; the 4Runnier back seat is a forgiving one.

Tips and Tricks:

At a scant 66.5 inches wide (71 in the Limited edition) and 178-183 inches long, the 3rd generation 4Runner is significantly smaller and narrower than its later brethren, which makes successful 3 across installations a much greater challenge than it is in later years. You’ll definitely be using your seat belts to get the very few workable installations to work, and even then, it’ll be a struggle. However, it *is* possible with a lot of effort.

3 Across Installations: Which Car Seats Fit in a Toyota Prius C?

The Toyota Prius C (the c stands for city) is one of the most fuel-efficient vehicles you can buy today in the United States, and is easily the most fuel-efficient non-electric car in the minicar segment, competing with other gas-sippers like the Honda Fit, Toyota Yaris, Ford Fiesta, Hyundai Accent, Kia Rio, and Chevrolet Sonic. Popular among the young and old alike, the Prius C may be a particular favorite of ecologically conscious parents who wish to leave their children a better world and promote a more sustainable future.

Ultimately, I fervently believe that the future isn’t in the giant vehicles that roam our streets and highways, but in much smaller vehicles like the C, and indeed, in far fewer personal vehicles (bicycles aside!) and in far better public infrastructure. But I’m getting ahead of myself. This guide is about 3 across compatibility, not sustainability!

I borrowed a Prius C this weekend to see how family-friendly it is when it comes to the all-important task of fitting multiple car seats into the back row. Before looking at which seats fared best, however, it’s worth taking a look at why it’s important to use certain seats at certain times with our children.

First of all, infants, toddlers, and preschoolers are safest when rear-facing. I recommend rear-facing as long as you can (ideally until 4!), before forward-facing them in harnessed convertible or combination seats (ideally until 8!). Once they outgrow their harnessed seats, I suggest keeping them in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). What we want to do is keep our kids restrained in the safest positions for as long as possible to increase their odds of surviving crash forces.

Keeping these ideas in mind, I set to work to find which infant, convertible, combination, and booster seats would work best in 3 across combinations in the Toyota Prius C. I found several good options and a few great ones. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

Tips and Tricks:

The current generation of the Toyota Prius is barely 157 inches long and 67 inches wide, making it one of the narrowest vehicles I’ve ever tried to stuff 3 car seats into. However, it’s definitely possible if you use the seat belts (no way no how when it comes to LATCH) and take your time.

Out of the above convertibles, to be honest, I’d really just go with the Fllo or Foonf, as the Radians will take up a lot of front-to-back space that you really don’t have, while the Coccoro won’t be the best value for your money unless you have the specific needs to merit it over the Fllo / Foonf.

If you’re looking for an infant seat, go with the KeyFit 30. It’s light, narrow, and puzzles well with itself in small spaces.

If you insist on using one of the Radians, you’ll definitely need the angle adjuster, or you’re not going to have any front-passenger space to speak of.

3 Across Installations: Which Car Seats Fit in a Mazda CX-5?

The Mazda CX-5 is one of the hottest entries to the small SUV / crossover market in the United States in recent years. It competes directly with luminaries such as the Honda CR-V, Nissan Rogue, Toyota RAV4, Ford Escape, Subaru Forester, Jeep Patriot, and Jeep Compass among families interested in the raised height of an SUV while retaining the fuel economy of a mid-sized car. The CX-5 is also a strong contender in my personal list of small, safe vehicles, with good small overlap, moderate overlap, side impact, and roof scores, as well as with ESC and side airbags.

In other words, the CX-5 is a solid little SUV, and it makes sense that families around the country are increasingly turning to it to transport their kids. I borrowed one this weekend in effort to find out just how good of a crossover it is when it comes to fitting 3 car seats across the back seat. The bad news is that while it’s a great vehicle on paper, the middle seat will make 3 across installations just about impossible. However, it’s worth taking a look at some best practice principles before checking out which seats will at least work in 2-across outboard installations.

The safest configuration we know of when it comes to vehicle safety is rear-facing. This goes for adults as well, but it’s uncommon to find rear-facing seats for adults outside of trains. That said, rear-face your infants, toddlers, and preschoolers for as long as possible (ideally until 4!), before forward-facing them in harnessed convertible or combination seats (ideally until 8!). Once they outgrow their harnessed seats, it’s best to keep them restrained in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). We want our little ones in the safest positions we know of for as long as possible to give them the greatest advantages in a collision.

Keeping these ideas in mind, I set to work to find which infant, convertible, combination, and booster seats would work best in 3 across combinations in the Mazda CX-5. It’s my goal to make this list the most thorough on the Internet. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

What this means is that you’re still going to have to focus on the narrowest seats and seat belt installations to make 3 across setups work. Keep in mind that you’re not going to be able to fit Cleks forward-facing in the center seat, although they’ll be just fine rear-facing. As always, to maximize front-to-back space while rear-facing, consider using a Diono convertible with an angle adjuster once your children have developed head control (which typically occurs around 6 months but will vary from one child to the next).

Special notes:

The R100/R100/KeyFit 30 installation is courtesy of a reader named Rob; he sent it in with notes that he installed the KeyFit with LATCH passenger outboard (with a pool noodle between the base and the R100 in the center to make removing the carrier easier, although it was unnecessary for the installation), one R100 FF driver outboard with LATCH, and one R100 RF center with the lock off plate (because the shoulder belt retractor alone wouldn’t work). The RF R100 was used with an angle adjuster and he also top tethered it to a bar beneath the center seat.

I tried the above installation with a pair of R120s and was able to replicate it, although it was a challenge. As Rob noted, all seats were independently tight.

If you’re not using those seats…

The current generation Mazda CX-5 is unfortunately almost completely not a 3-across compatible vehicle due to the extremely narrow and oddly-designed center seat. Because the seat is split in a 40/20/40 way in order to make room for additional cargo in the rear, the center “20” section is too narrow to be usable in a vehicle of this width. On top of that, the buckle for the seat is also oddly-designed.

I’ve included 2 car seat arrangements that will work easily given the available space in the CX-5, but until Mazda corrects this, the CX-5 will remain a primarily 2-across vehicle.

Tips and Tricks:

The first generation of the Mazda CX-5 is 179 inches long and 72 inches wide, or about the width of the typical mid-sized sedan. As a result, you’d expect there to be fair amount of different seats you could make work within the CX-5. However, it’s a no-go due to the middle seat. It’s too narrow, and makes the CX-5 primarily a 4-person vehicle, which is very unfortunate.

I’d definitely recommend using your seat belts instead of your LATCH anchors to give you a few precious extra inches when dealing with particularly wide outboard-placed seats.

The 6 Narrowest Car Seats that Will Fit 3 Across in Any Vehicle

A Guide to Narrow Car Seats that will Fit 3 Across in Nearly Any Car
With the right seats (e.g., 3 Foonfs or 3 Fllos), you can make 3 across work in just about any passenger vehicle sold in the US or Canada, as long as the vehicle has 3 seats.

If you’ve got three or more kids, you know how difficult it can be to get them all buckled into your vehicle safely. It’s why I created the 3 across car seat guide, which has more than 60 different cars, minivans, SUVs, and pickup trucks listed so far. My goal was to help parents figure out which 3 sets of car seats were most likely to fit into their particular vehicles, taking into account how models often changed dramatically from one generation to the next, and how some seats simply puzzled, or fit, with particular seats in better or worse ways.

Which car seats are the easiest to install in my car / truck / SUV / minivan?

I’ve received hundreds of emails from parents over the years thanking me for the guides for their particular vehicles or requesting more specific advice. However, one of the most frequent questions I received involved a request for car seats that would work in pretty much all vehicles without lots of struggling, stubbed fingers, or the weight of ten Sumo wrestlers to hold them in place while tightening seat belts or LATCH straps. This is that guide.

Here are the 6 safest car seats that will fit 3 across in just about any vehicle. They’re not going to help you do the impossible, such as 3 across in a Smart Car or in a car that doesn’t have a back seat at all. But they’re going to work in pretty much any other normal, street-legal vehicle made in the last 20 years. Buy 3 of them and forget about car seats for a while; if you’ve got 3 kids, you’ve got more than enough to keep you busy.

Remember, of course, to use your seat belts for installations instead of LATCH if you have any trouble fitting your seats together, as you can often gain several inches with 3 seat belt installations over 2 LATCH + 1 seat belt or 3 LATCH installations. And if you’re in a smaller vehicle, every inch is precious.

The 6 narrowest (yet safe!) car seats that will help you get 3 across in nearly any vehicle, guaranteed.

flloinkClek Fllo – 17 inches. Review here, buy here.

The Fllo is easily my favorite car seat on the market right now when it comes to a seat that you can buy 3 of and rest easy knowing that it’s going to fit in your car. It doesn’t matter if you drive a Fiesta, a Fusion, or a Yukon; you’re going to be able to get 3 Fllos to fit in it, and fit well.

And when you combine the Fllo with the Infant-Thingy infant insert, you’ve got a seat that you can use from the day your baby leaves the hospital until he or she weighs 50 pounds. And after that point, you turn it around so it’s forward-facing and you’ll get another year or two out of it until your child reaches 65 pounds. It’s not the cheapest seat on this list, but when it comes to a set-it-and-forget-it seat that lets you rear-face longer than any other seat on the market (besides a handful of seats including its sibling the Foonf), the Fllo is the best convertible seat you can buy.

foo2Clek Foonf – 17 inches. Review here, Buy here.

The Foonf is like the Fllo except it has a few internal and external differences. It also costs more, weighs more, and sits up higher, making it more difficult to see behind. However, if you have the specific needs that draw you to the Foonf over the Fllo, or if you can find one at a discount, you’re still going to get one of the absolute best seats on the market for 3 across.

At 17 inches, it’s every bit as narrow as the Fllo and every bit as easy to use to get a 3 across installation in. And just as with the Fllo, you can pair it with the Infant-Thingy infant insert to get a seat that’ll be usable rear-facing from 4 to 50 pounds and then usable forward-facing until 65 pounds. You can compare the Fllo and the Foonf to decide which is the best choice for you, but if you can’t think of a reason to go with the Foonf, save some money and go with the Fllo.

rxtDiono Radian RXT – 17 inches. Review here, buy here.

The Radian RXT is an excellent car seat overall, but it’s a particularly great one when it comes to 3 across installations, simply because it’s narrow, it’s been out for so long that people have had a chance to test its durability (and yes, it’s a very sturdy seat), and because it’s the first seat on this list that can be used for a great amount of time while forward-facing in addition to rear-facing.

The rear-facing weight range is 5 to 45 pounds, meaning you can use it from the day your baby leaves the hospital until s/he’s probably around 4 or 5. The rear-facing height limit is 44,” which give you a good amount of time. You can then turn it around and forward-face until your child weighs 80 pounds or is 57″ tall, which is considerably more in height and weight than what you’ll get from the Fllo or Foonf.

It even has a booster mode that extends up to 120 pounds, although you may not get to fully use it if your child exceeds the height limit of the seat belt guide, which is unfortunately fixed. Overall, the Radian RXT remains one of my favorite convertible seats and is definitely a seat you can trust to get you a 3 across installation without fuss or muss.

120Diono Radian R120 – 17 inches. Review here, buy here.

The Radian R120 is basically a cheaper version of the Radian RXT; the only real difference between the two seats, besides the price and the fabric options, is that while the Radian RXT comes with head wings, the Radian R120 does not. The head wings are meant to offer head protection from side impacts, so it’s up to you whether you think the price difference is worth it or not. Personally, I do think it’s worth the difference, but I still think the Radian R120 is a strong seat and it’s still one of the best out there for 3 across installations. As with the Radian RXT, you can use it to rear-face from 5 to 45 pounds, to forward face until your child reaches 80 pounds, and to booster until your child reaches 120 pounds.

The Radian R100 is basically a cheaper and slightly stripped-down version of the Radian R120, which itself is basically a slightly stripped-down version of the Radian RXT. It remains an excellent seat for 3 across installations despite its changes, but it’s worth noting that its changes are more significant than those of the R120.

Your rear-facing limits are now 5 to 40 pounds while your forward-facing weight limit drops down to 65 pounds. Your booster range also drops down to 100 pounds. In other words, you’re not going to get as much time in each stage with this seat, which is why I’d recommend the other two Dionos before it. However, it’s still quite competitive among seats out there in terms of the time limits it does offer, and it’s still well worth consideration, especially if you’re on a smaller budget.

Last but not least, the Combi Coccoro deserves a special mention as by far the lightest of the seats I’ve mentioned so far, which makes it the seat you’re most likely to appreciate about if you’re constantly needing to change vehicles with your seat, but still need as narrow of a seat as you can get for 3 across installations.

That flexibility does come with a cost; it has the lowest rear-facing weight limit of any of the seats here at 33 pounds, but it also has the lowest starting rear-facing weight range at 3 pounds, meaning it can be used with very, very small babies (preemies) safely. The forward-facing weight limit is 40 pounds with a 40″ height limit, which does mean children will outgrow this seat sooner than they would any of the other seats on this list. That said, if you’ve got particular needs, such as extreme portability, very small babies, or if you simply want a seat as small as an infant seat that still offers some of the advantages of a convertible seat, this might just be the one you’re looking for.

All the seats you recommended are convertible seats! Am I allowed to use one of these when leaving the hospital?

Yes! I wrote an article about this the other day to address a number of new parent concerns about leaving the hospital (or clinic or birthing center) without a typical, rear-facing only infant “bucket” car seat. The truth is that you can do it as long as the convertible seat properly fits your child and is safely installed in your vehicle.
