Best Convertible Car Seats 2017 - Safe, Comfortable, & Reliable
Looking for less expensive convertible car seat options? Check out our reviews here.
As a baby of the 70's my dad would lay a blanket down in the back of his Saab hatchback and let us crawl around and play on long road trips through snowy Maine. No car seats, no seat belts in the back seat; just slippery roads and some dumb luck. Somehow we got out unscathed, at least physically. Fortunately car seats, and parents, have come a long way since the 70's!
Some History: Not to bore you to death, but in the late 90's Britax released the first convertible car seat in the U.S., the Britax Roundabout. Rather than having a separate rear-facing infant seat and then a different forward-facing toddler and "big kid" seat, the convertible offered the convenience of a car seat that parents could simply turn around when their baby was tall and heavy enough to be forward-facing. This concept was very new for parents and the car seat market, and people were somewhat slow to adopt the new concept. Fast forward 10 years and convertible car seats became the fastest growing segment in the car seat market. Now, fast forward another 10 years and you'd be hard-pressed to find a parent who hasn't considered or purchased a convertible car seat.
What is a convertible car seat? The concept is great. Convertible car seats begin as rear-facing for your infant and then transition to front facing when your baby meets size and weight requirements. Usually this happens around 2 years of age, but in the meantime the convertible car seat can stay rear-facing but with a more upright tilt/stance. They also grow with your child, typically with adjustable shoulder strap height, crotch buckle position, recline/tilt, and head rest. If you're not worried about losing the convenience of a carryable infant car seat with a folding handle (we review those here), then this is definitely the option for you! Convertible car seats can save you a lot of time and money versus buying an infant seat and then a separate toddler seat, and let you spend a bit extra on a nice stroller (our stroller reviews are here) or, god forbid, something nice for mom. But overall, our honest recommendation is to go with a dedicated infant car seat and then transition to a convertible at around 10-12 months of age, or earlier/later as your baby's weight and height dictate.
What to look for: There are a few things you should look for when trying to find the right convertible car seat. First, because you buy a convertible car seat to last for many years, avoid the hassle of shoulder straps that need to be rethreaded for adjustment. You will find that many well-rated convertible car seats require re-threading (particularly the inexpensive ones, which we review elsewhere). Second, if you're going to use the convertible car seat as an infant seat, then you want to make sure that it is capable of reclining far enough to make for comfortable rear-facing infant positions. If it does not, then your baby's head will flop forward when they fall asleep. Third, get a convertible seat with a wide weight range so it will last your child for many years; a good start is from 4 pounds to over 100 pounds. Finally, always buy new and go with a reputable brand so you can be confident that the seat is safe. Never buy a used car seat. Even if the owner is being honest about having no accidents, sometimes smaller bumps can lead to micro-fractures and weakness, so steer clear (no pun intended).
What we did: To find the best convertible car seats of 2017, we got 7 experienced moms together to review a set of 11 popular convertible car seats, and then conducted a large focus group to gather opinions from real moms without anything to lose from being honest. We included all of the major brands (RECARO, Baby Trend, Graco, Peg Perego, Maxi Cosi, Britax, Safety 1st, and Evenflo). We did a thorough hands-on test of each unit, let our kids sit in them and give opinions, tested how stain-proof the fabric was, and gathered honest opinions, reviews, and ratings from fellow parents. What remained after this process was a group of 7 truly excellent convertible car seats that met and exceeded our expectations. These are listed below.
1. Graco 4ever All-in-One Car Seat, multiple patterns and colors. About $250 to $300, depending on color options. Given the longevity of this seat, we think it's worth every penny! All of our reviewers agreed that this was the most versatile, comfortable, and functional convertible car seat available. It truly is an all-in-one seat, accommodating a weight range from 4 to 120 pounds. The secret is that it starts as a rear-facing infant seat (4 to 40 pounds) with a plush and removable infant insert. Then it transitions to a front-facing toddler seat (20 to 65 pounds) without the infant insert. Then it transitions to two different types of booster seats, one with the highback still on it to position the vehicle's seat belt (30 to 100 pounds), and then finally you remove the back completely for a bottom-seat-only booster (40 to 120 pounds). Given how low the infant weight range goes (4 pounds), this can be a great option for premature babies. This is the most versatile convertible car seat on our list: not only does it convert from an infant to toddler seat, it also converts all the way to a bottom-only booster. To meet this lifespan, the seat is rated for up to 10 years of use! In addition to that awesome versatility, there are a ton of other positive features here. First, the shoulder belts and headrest are easily adjusted using a handle positioned on the top (no rethreading ever needed). Second, the recline handle is right on the front and adjusts to a wide range (6-positions) of backseat slopes: this allows you to get the correct recline when used in rear-facing infant mode: as your infant gets larger, you will want less of a recline, even when rear-racing. The color-coded recline settings on the side were a nice touch, helping you understand how much recline is needed for each configuration. It also has a built-in level to help you ensure the "base" is mounted in an ideal, level position. Third, the InRight LATCH system is awesome and makes life easier when you need to pull it in/out of different vehicles. Instead of the traditional "hook" LATCH, which is a pain to remove for quick-swapping between vehicles, the InRight LATCH system has a red button that you press to release the clip. Of course, it also has easy-to-use seat belt pass-throughs for vehicles without the LATCH option. Fourth, we found it generally comfortable and soft, and very supportive for even very little (4 pound) babies, with the included infant insert. The fabric is not quite as soft, plush, or breathable as the RECARO (below), but it has a clear advantage: you can remove and machine wash it! Finally, it comes with two nicely positioned cup holders: for babies, these can be used for storing toys, and for toddlers they can be used for sippy cups and snacks. Overall, we think you really can't go wrong with this safe, sturdy, well-made car seat, and it is very deserving of the #1 spot on our list. Note that if you like the look, feel, and features of this seat, but don't need such a wide weight range, consider the Extend2Fit Convertible Car Seat, which fits from 4 to 65 pounds.
2. Diono Radian RXT All-in-one Convertible Car Seat, several colors. About $300. Expensive, but truly a very high quality, safe, reliable, durable, and comfortable convertible car seat that accommodates a wide range of baby shapes and sizes. The Diono Radian series is well-known for making one of the narrowest convertible car seats on the market. Looking to fit more than 2 car seats in the back some day? Then this is probably the best bet for you, coming in at only 17" wide (if you take off the cup holder). This means that you can fit three across in the back seat of most cars. This is a no-compromise convertible car seat. It uses a full steel alloy frame with aluminum sides for super strength and rigidity, thick energy absorbing EPS foam side impact protection, a Safe Stop energy absorbing harness system for bigger kids (20-40 pounds, front-facing), and a top tether for rear-facing applications to decrease seat rotation in the event of an impact. It also uses the SuperLATCH system, which makes attaching and detaching the seat easy and secure, with a nice visual indicator so you'll be confident that it's attached correctly. With all that safety, it's got a lot of bulk and weight, coming in at over 20 pounds heavy! One of the only steel frame convertible seats on the market, we think that's OK unless you plan to do a lot of air travel or constantly switch it between vehicles. We also thought the car seat was super versatile: rear-facing from 5 to 45 pounds, front-facing toddler from 20-80 pounds, and booster (bottom only) from 50-120 pounds. That's basically from birth until your child is a "tween"! For the smaller babies, down to 5 pounds, there is a comfortable removable infant insert that nicely supports the hips and head. The range of adjustments were really wide and very easy to use. The head rest adjusted between 12 different height settings, the shoulder belt between 5 different height settings, and the crotch buckle between 3 different positions. It also has nifty adjustable sides that angle in and out to provide more or less support for growing thighs. So as your baby grows into a toddler and beyond, they are sure to be comfortable with ample customizations. Speaking of comfort, the fabric was high quality, soft, and nicely padded; not quite as plush and comfy as our #1 pick, but really great. It was also easy to spot-clean, and machine-washable for larger spills and odors. Another feature we loved is that it can fold up for easier transport; so while it's quite heavy, it is FAA certified for taking onto an airplane, and folds flat to make carrying a bit easier. We found it could be carried like a back-pack, and it also sat nicely on top of a larger wheely-suitcase. Oh, and it has a little cup-holder that's removable for tighter fits. So overall, this is an excellent, safe, versatile car seat. A bit more expensive and less plush than the Graco 4Ever, but definitely worth the price if you ever plan on squeezing 3 seats in a row or have a smaller vehicle where every inch counts!
3. Evenflo Symphony DLX Convertible Car Seat, in several colors. About $170-180. This convertible car seat has a great weight range, accomodating babies, toddlers, and big kids from 5 to 110 pounds! With an upper weight capacity like that, this might very well be the only car seat or booster you will ever need to buy. You can use it rear-facing up to 40 pounds, forward-facing for toddlers up to 40 pounds, and then as a high-back booster up to 110 pounds. Note that the high back isn't removable, so there is no option for a bottom-only booster (like with the 4Ever, above). The seat itself is heavy, coming in at about 25 pounds; it is made in the USA and is built tough to protect your baby and last your family for many years. We thought the Sure LATCH system was awesome, you no longer need to pull to tighten the latch, just simply push it down and you'll see it self-tighten. This is a really helpful system. The adjustable height harness is very easy to adjust upward as your child grows, without any rethreading hassle. The shoulder harness adjustment strap is right up front, as is the recline handle to help you get it perfectly level in the back seat of your unique vehicle. It also has two built-in cup holders that can be used for bottles, sippy cups, and toys. However, we didn't like how the cup holders were actually half of a cup-holder with an elastic strap on the outer side. In other words, you can't put anything other than a rigid object (bottle/sippy cupe) in there without it falling right out of the side. So no snacks or small toys in there. In our tests, we thought the cushioning on this seat was fantastic, supportive, and easily cleaned. It has removable cushions for infants, and they are incredibly comfortable. More negatives? Well, it doesn't have highly breathable rear cushioning so if your baby heats up easily they will probably sweat more in this seat than the RECARO or Graco 4ever with side mesh. Note also that this particular seat, with its huge side impact wings, is really quite large. Might not be suitable for rear-facing in some relatively small vehicles.
4. Graco MySize 65 Convertible Car Seat with Rapid Remove Cover, multiple patterns and colors. About $160. If you have a premature baby that's below 5 pounds (but at least 4 pounds), this might be the seat for you. Like the Graco 4ever, this convertible car seat goes as low as 4 pounds with the included infant insert, but this model only goes up to 65 pounds. The seat itself is 19.2 pounds, which is relatively light on this list. It has special inserts that support even the tiniest of babies, and some of our tester moms thought this was awesome and seemed like it would be very supportive for even the smallest newborns. It uses a multi-position (5 positions on this one) harness and headrest that adjusts using a lever to pull it up or down to fit your baby's size. It also has 3 recline positions to suit most vehicle's seat positions, and a little cup holder that will definitely come in handy, and collect crumbs through the toddler years! Like the Graco 4ever and Evenflo options, but unlike the RECARO, this Graco option has a machine washable cover that you can pull off really quickly; just take it off and throw it in the wash. The fabric is soft and breathable, but not quite as much as the Graco 4ever or the RECARO. So while it's cushy and comfy, the fabric isn't quite as soft as some others. The side impact protection seems substantial, though it does feel like it's not quite as sturdy as other options. However, the somewhat smaller side impact wings make it a bit easier to fit into more space-constrained vehicles. This makes it a good alternative to the Symphony if you have a smaller vehicle (like a compact or economy car). We also found it a bit tough to tighten the harness properly at times, the bottom buckle was a bit too large for chubby baby thighs, and the upper chest buckle was a bit harder to unbuckle than the other options on this list. But at $160 we believe this car seat is a great deal: you get a comfortable, safe, versatile car seat that will last you for many years!
5. RECARO Roadster Convertible Car Seat, multiple patterns and colors. About $215-240 depending on color options. We all came to agreement that this Roadster was a truly excellent convertible car seat, with some great advantages over many other seats on the list. The design is relatively simple but with a flare for dramatic racing colors and style; it's made by RECARO after all, which has a long history of making high-end racing seats for sports and luxury cars. We really loved the side impact protection on this seat, with really large pillow-like head wings to protect the head and face, and substantial reinforcement all along the sides. All of our reviewers thought the seat felt very secure and supportive; there is nothing flimsy about this seat, it feels very well constructed, including the frame and fabrics, and it is super comfortable. Not surprising really, given that it uses memory foam in the seat! The safety harness adjusts very easily (and without rethreading) to babies from 5 to 65 pounds without requiring any annoying re-threading of the straps; the seat uses a clever knob that adjusts the straps and head rest up and down to accomodate a growing baby. The seat itself weighs a bit over 20 pounds. There's a rear-facing recline lever that allows you to adjust the seat to your vehicle's seat position, a built-in LATCH system with lower straps and a top tether, and we loved the great mesh ventilation system along the sides that will keep your baby from getting too clammy. This seat is certified by RECARO for 6 years of use before expiration. Relative to the old ProRide model, this seat uses a high impact energy absorbing seat, Cloud Comfort memory foam, and a new patented twist-resistent shoulder straps. And they weren't kidding, those straps stay right in their intended position, no twists or other nonsense. The one negative we found with this seat is that it is very big!. One of our testers tried fitting it into her Honda Civic's small back seat. It fit quite well, but it was very tall, making it somewhat hard for her to see through her rear-view mirror when it was rear-facing (this is not specific to the RECARO). And the front passenger seat couldn't slide very far back when it was installed rear-facing. Not an issue when front-facing. Other Downfalls? Well, the cover is not machine washable. You can remove and hand-wash and line dry, but do not attempt to put it in the washer or dryer; things will get mis-shapen and ill-fitting. This makes some sense given all the extra padding and memory foam that makes this so dang comfortable. Outside of that, we think this is a truly excellent convertible car seat and we strongly recommend it.
6. Peg Perego Primo Viaggio Convertible Premium Car Seat. About $350-400 depending on color options. This is a newer edition of the excellent series of Peg Perego infant and convertible car seats. Much pricier than the competition, but for some good reasons. First, we really liked the fact that the rear-facing weight limit of the Peg Perego goes all the way up to 45lbs. Not many car seats came close to this weight limit and this is extremely useful given the recommendation by the American Academy of Pediatrics that that children be rear-facing until at least 2 years of age. For maximum safety, they advise keeping your baby rear-facing for as long as the car seat allows, and this one reasonably allows you to keep your baby in the safer position for a longer period of time. Second, this is a very safe car seat with great side impact protection; Peg Perego uses shock absorbing foam on the sides of the car seats as well as below the seat to protect your child's head, neck, and spine in the event of an accident. In our tests, we found that this car seat is also extremely easy to install, and the buckles worked very well for quickly getting the child in and out of the seat. The fabric is breathable and easy to clean (a big plus when your child spills milk all over the seat!) and the seat is heavy and big, but nothing ridiculous (21lbs). Overall, this is a great car seat and would have been higher on our list if it weren't for the price; at $350-400 it's more than twice the price of several other options.
7. Chicco NextFit Zip Convertible Car Seat, multiple patterns and colors. Usually about $350, though the non-Zip version without a machine washable zip-off cover is a bit less expensive. The seat comes in at a whopping 26 pounds, easily the heaviest on our list; but remember, this is a convertible car seat so it will likely be staying in your car 99% of the time, unless you need to swap it between vehicles a lot. The seat supports newborn babies using the included infant insert, starting at 5 pounds and going up to 11 pounds. It supports up to 40 pounds in rear-facing mode, and then up to a very high 65 pounds in front-facing mode. There were certain things we really loved about this car seat. First, the easy to read recline indicators have an intuitive numbered system for recline levels appropriate for rear- and front-facing modes. They also included bubble levels to make sure you have things positioned appropriately. Second, the Zip-off washable cover was brilliant, we were really impressed with how easy it was to remove the cover and throw it into the wash. It was also easy to get back on. In our opinion, the Zip feature is worth every penny, and you will realize why the first time you have vomiting or a diaper explosion during a drive! Third, we loved how the lower straps of the harness automatically flared outward when unbuckled, to make it easier to slide your baby in and out. Fourth, the Super Cinch LATCH system made life much easier when attaching the seat; of course, it also can be attached using the conventional back seat belts. Finally, we thought the side impact padding was substantial and the headrest was easy to adjust up and down. So there are really a ton of great features here. We also thought the fabric was soft, breathable, and comfortable, while also being easy to wipe clean with a cloth as needed. So why is it down here on our list? Well, if you compare it feature for feature to the Evenflo, Graco, and Recaro options above, you realize that it doesn't really stand out in any particular way except for the higher weight and higher price tag. We also found the shoulder strap tightness very difficult to adjust when the seat was rear-facing, as it is up against the rear seat. Also, the detachable cup holder isn't super easy to use, and the crotch strap was great for babies but not so well positioned for bigger kiddos.
8. Evenflo SafeMax Platinum All-in-one Convertible Car Seat. About $240. This relatively new-to-market convertible car seat has some great potential, and we were happy to get our hands on one for testing! This seat has an impressively wide weight range, supporting babies and kids from 5 up to 120 pounds: 5-40 pounds rear-facing, 22-65 pounds front-facing, and 40-120 pounds as a high-back booster. At its limits, it can support babies as small as 19" tall, and as big as 57" tall (usually around 11-12 years old). In our opinion, you'll likely switch over to a bottom-only booster long before you'll hit the age and height limits, so it's probably a pretty small niche audience that will need this seat over about 80 pounds. With that huge range of height and weight support, the seat itself is also really enormous, coming in at about 25 pounds heavy, and just under 23" wide. If you're thinking about putting the seat into a smaller vehicle, or thinking that you might eventually have a need for 3 in a row in the back seat, this is definitely not the seat for you! Coming in at around $240, this seat is in the upper middle of our price range, so you will also expect a lot of features. And it delivers in this area, particularly when it comes to safety. Like the Diono, it has an integrated steel frame for stability and strength, and also uses large side impact and head supports, a 5-point harness, is FAA approved for air travel, and uses the new easy-connect and disconnect LATCH system. It also has a lot of great convenience features, including multiple recline positions, an easy-adjust harness height, and two cupholders. The cupholders have removable inserts, the cover is easy to remove (using some zippers) and machine washable, We found no evidence that it uses EPS energy-absorbing foam, however, and there were a few issues we encountered during installation and use. First, the seat was a bit difficult to install; this is partially because it is so large, but also because it is missing a handy bubble level that can make judging incline much easier. Second, converting this to a booster was quite a chore. Hopefully you'd only have to do this once, but if you're imagining being able to use this flexibly for different-sized kids, the difficulty of that conversion would be a deal-breaker. Third, did we mention how large this seat is? It's really huge! Putting an infant in here looked ridiculous, and the infant padding inserts weren't all that substantial and comfy: you'd be better off with some of our higher-rated seats for making sure you have a comfortable infant fit. Finally, we didn't think this seat breathed quite as well as some of the others, making for a sweaty baby during summer months. Overall, this is a great seat, but where it excels in upper weight limits, it underperforms as a seat for smaller babies and more compact installation requirements.
9. Britax Marathon G4.1 Convertible Car Seat, multiple patterns and colors. Between $200 and $280, depending on color and pattern options, and coming in at only 17 pounds. It is rated for 5-65 pounds. No, we don't own shares in Britax, but we are certainly considering it. The company never fails at appearing in our "best of" lists for infant car seats and convertible car seats. Britax does it well, and has been doing it for a long time. The Britax Marathon is the flagship convertible car seat, and it is excellent. Britax prides itself in a top-notch safety record, quality construction, and comfort. This car seat has great side impact protection, 10-point quick-adjust harness system, adjustable recline, and it feels very sturdy and comfortable. The fabric is also nice, but not machine washable. Overall, this is another excellent choice by Britax. While Britax is never inexpensive, the seat does have some great features, and it comes with the Britax reputation for quality and safety. But overall it's quite simple, doesn't have a great weight range, and is not as comfy and plush as other options. We also found the crotch strap to be a bit short, resulting in the lower straps digging a bit into chubby baby thighs. Finally, we have a warehouse full of various used car seats, and have discovered that many of the Marathons have torn/ripped cover fabric, especially along the seams. We don't tend to see that with many other brands, particularly ones as this price point. If you're finding yourself on the upper end of the price range because of your color options, may we also suggest checking out the Britax Boulevard. The Boulevard is the higher-end seat, but very similar in most regards. From what we could tell, the key differences are that the Boulevard is a bit beefier and heavier, providing more shoulder room for the child. Also has a bit more padding behind and to the sides of the head, and provides a softer infant insert. But the added comfort and safety comes with some added cost, with the Boulevard coming in about $30-40 more than the Marathon. Overall, the Marathon is a great option for those who want the Britax brand and are willing to compromise a bit on comfort, style, and durability.
10. Maxi Cosi Pria 70 Convertible Car Seat, multiple patterns and colors. About $250 depending on colors, and about 18 pounds. It's called Maxi Cosi for a reason, this thing is really maximum coziness in a car seat. Definitely the softest one of the bunch, with the most comfortable padding and support. If you're looking for the cushiest car seat out there, this is the one for you! Also, if for some crazy reason you're looking for a leather car seat, this is the only brand that we know of offering one this year! The Maxi Cosi Pria isn't the cheapest on our list, nor the most expensive. It's not the most fully featured, nor the least. But one thing is for darn sure, it is one of the softest and most comfortable car seats your baby will ever sit in! With several different styles and colors (click the picture to see more options), there seems to be something for everyone's tastes. Note that while most of the convertible seats on this list cover from 5 to 65 pounds (or higher), this one covers from 9 to 70 pounds. If you want it to go higher, check out the Pria 85. So it's sort of in an odd position: most newborns are less than 9 pounds, so unless you have a chunky monkey you'll need to get the Pria 70 with the Tiny Fit insert that supports newborns (down to 4 pounds). The Air Protect side impact protection is a bit like the pillow of the RECARO and Evenflo, and the cup holder a bit like the Graco. The Maxi Cosi has 3 recline positions, a multi-position quick-adjust harness and headrest, and super soft cloth that will make you smile every time you slide your baby into this little lounge chair! When they make one of these for grown-ups, please contact us to let us know, we'll be first in line! Downfalls? The recline options seemed limited, the fact that you need to buy a separate insert to support infants under 9 pounds seemed odd, and the buckle release button was sometimes very hard to press down. Finally, several moms commented that there have been some quality control issues with the center adjustment strap, noting that it frays after about a year of use.
