If you like the idea of one convertible car seat from infant until the last day a child seat is required, then the Graco 4ever All-in-One Convertible Car Seat is the best combination car seat for you. 

Truly an all-in-one, this car seat gives you 10 years of use from 4 to 120 pounds in four modes - infant rear-facing, toddler front-facing, booster seat in high back and backless belt-positioning mode. We especially like the 10-position headrest and easily adjustable harness system.

For an all-in-one, Graco 4ever is surprisingly small at 20" wide, 24" tall and 21.5" front to back. This will definitely fit in most small cars, although we don't think it is one of those fit-3-across type because you will need something narrower for that. 

For one that holds up to 120lbs, Graco 4ever  weighs 23lbs only. While this is certainly not light, we know there are other models that are much heavier, but with a lower weight capacity. Nonetheless, it is one of the best booster car seat because not many offers a weight limitation of up to 120lbs.

Nonetheless, Graco 4ever is not meant for portability (there are other car seats meant for that) because of its weight. Once it is installed in your car, you will want to treat it as a permanent feature of your car, and you should, since it will last you 10 years!  

Graco has many other different models but in terms of choosing the best Graco convertible car seat, we think the 4ever All-in-One is the best rated convertible car seat because with this one, you truly do not need any other attachments/add-ons to last you a good old ten years! 

Looking for the best budget convertible car seat? Evenflo Tribute LX Convertible Car Seat will delight you!

This convertible car seat has a width of 18.5" only, making it one of the best convertible car seat for compact car. 

Weighing at 9.1lbs only, this is also the best lightweight car seat that you can move around from car to car without straining the muscles. Because it's so light, parents have commended it being the best travel car seat.

Nonetheless, it also means that it is not packed with too many add-ons or cushioning, and you may find your little one sort of swimming in the seat if s/he is on the smaller side because the harness lacks the additional padding.  

Don't get us wrong, there is nothing wrong with the cushioning of this car seat, it is just that most other brands provide additional ones to give better support (which is also reflected in their prices). Given the price of the Evenflo Tribute LX, you can easily solve this by buying one of these bestsellers to wrap around the harness and it will still be cheaper than other car seats.

Price aside, the quality of this car seat will exceed your expectation. Made in the USA, it meets all standard safety requirements (and more) as it is designed and tested for structural integrity at energy levels almost 2x the Federal crash test standard. 

This car seat is reclinable for rear-facing use, but you do have to adhere to the weight requirements of 5-40lbs and it mostly fits babies age 18 months or below.

All in all, for what you pay for, the Evenflo Tribute LX Convertible Car Seat meets all requirements and more. Not only is it the best cheap convertible car seat, it is also the best value convertible car seat that you will not regret buying. 

Remember we mentioned in the beginning of this review that the safety angle of rear-facing car seats is one of the reasons they are troublesome to fit into small cars? 

Chicco addresses this issue with its Next Fit Zip Convertible Car Seat. It didn't do this by making the Next Fit Zip the smallest or narrowest, although at 19" wide, it is still narrower than most average convertible car seats. Rather, it boasts a 9-position levelling system to allow for an accurate fit in a wide range of vehicles, which include smaller and compact cars. 

When you have that many reclining options, you can certainly find one angle that fits in your small backseat (rear-facing, on top of that) without compromising leg room in the front seat. This is the only convertible seat that provides that many recline options when most only have 3 or 5. Such adaptability is exceptional, really. 

It is also one of the best convertible car seat for tall babies because at 26", it is taller than most convertible car seats, making it comfortable for the taller ones.

We cannot mention the Chicco Next Fit Zip without mentioning its ease of installation. It has two ride right bubble levels to show you the correct seat angle in both rear-facing and forward-facing modes. You won't be cursing under your breath while installing this one, we guarantee!

This is definitely one of the best small convertible car seat that makes full use of every millimetre of your compact car without compromising your little one's comfort. If you are looking for the best reclining car seat , you won't go wrong with the Chicco Next Fit Zip.

Safety 1st Grow and Go 3-in-1 Convertible Car Seat is another one of the best rear facing car seat for small car that we would recommend.

This convertible car seat is designed to last through all your firsts with your child. Featuring extended use at each stage, you get three modes with this car seat - rear-facing from 5-40 pounds, forward-facing from 22-65 pounds and belt-positioning booster to up to 100 pounds. 

Similar to Chicco Next Fit Zip, this is for those who find that they have to compromise the front seat's leg room.  The Grow and Go is designed to prevent this by allowing up to 7" of extra leg room for parents sitting in front when placed rear-facing. 

For the newborns, this car seat also comes with two comfortable grow-with-baby pillows to give a snug fit. Once baby outgrows them, they can be easily removed. 

We love the harness holders of the Grow and Go. It is designed in a way that the harness is always kept in an open position so that it's easy to get your child in and out of the seat. Both harness and headrest can also be easily adjusted in one simple step. We think this is definitely one of the best harness booster seat too when your child utilises it. 

Safety 1st Grow and Go is among the best 3 in 1  car seat in the market. The promise of having 7" extra leg room makes it an attractive option, definitely the best rear facing convertible car seat for small car that you can't resist!

Diono Radian is well known for its slim fit design and its RXT All-in-One Convertible Car Seat is the best narrow convertible car seat out of all. 

This is another one of the best all in one convertible car seat that grows with your child from birth to booster. Unlike Graco 4ever, it does not have a backless belt-positioning mode but you do get rear-facing, forward-facing and booster mode up to 120lbs. This is pretty impressive as it will surely fit any kid through the booster years, making it one of the best rear and forward facing car seat. 

This car seat measures at 16" wide (really, you cannot go any narrower than that!) which makes it the best narrow car seat that can fit 3 across in most cars, unless yours is the exceptionally compact type which even then, you will have no problem fitting 2 without feeling congested. We also like how it folds flat so that you can even carry it on your back, making it one of the best convertible car seat for travel.

You will notice that the Diono Radian RXT has a taller frame than most other car seats. If you're worried it wouldn't fit in your small car, you can buy one of these to fit underneath the seat to hold it more upright (note: you can't use this for newborns). This allows it to extend its rear-facing seating ability to fit taller kids, in fact, it is one of the best rear facing toddler car seat in the market.

This is ideal for those that would like to have their kids rear face for as long as possible. We think it's worth paying the few extra bucks to extend the rear-facing benchmark reliably, given all the benefits of rear-facing.

For those that are having twins or triplets, Diono Radian RXT All-in-One Convertible Car Seat is the best compact convertible car seat to get because you can pack them side-by-side in your car, and they take you from newborn to booster seat age seamlessly.  

If the Diono Radian RXT is out of your budget, don't worry, we've got an alternative fit-3-across in Safety 1st Guide 65 Convertible Car Seat that is under $100. 

Its 18" width, 20" front-to-back dimension allows you to place three of them side-by-side in most vehicles. While it is not as narrow as the Diono Radian RXT,  it should still fit in most compact cars. 

The Guide 65 is one of the best extended rear facing car seat because it allows up to 40 pounds and 40 inches rear-facing, as well as 65 pounds and 52 inches forward-facing. The multi-position adjustable head rest ensures it grows with your children. 

This car seat is comparable to Evenflo Tribute LX in that they are both very affordable and lightweight, making them good options for travelling but the Safety 1st Guide 65 is 0.5" narrower, which makes it the Diono Radian in a simpler version, but not as expensive. 

While most car seats cater to accommodate newborns, not all provide the best fit/comfort, especially if your baby is on the small side. If this is your situation and you're looking for best infant car seat to fit into your small car, Maxi-Cosi Pria 70 is your answer. 

This convertible car seat is designed to provide the right fit for any size of infant to 7 years of age. This is thanks to the brand's removable infant insert that is made from plush premium fabrics with the ability to deodorise and draw liquids away from the skin to keep your baby dry and comfortable.

This insert makes sure your baby is tuck in snugly so that s/he will not 'swim' around in it. Parents with small babies and even preemies have raved about how well the Pria 70 is in terms of fitting their little one snugly and comfortably.

Not too wide at 19.5 inches, the Pria 70's 21 inches front-to-back dimension makes it the best compact infant car seat.  The deep recline adjustment system makes it easier and faster to correctly install in rear-facing position as it gives you more options to find the best fit for your compact car.  

In terms of providing the ultimate comfort seating area for baby, the Maxi-Cosi Pria 70 is the best infant car seat for compact car for that. There is no baby too small for the car seat with this one!
