As your child gets older and heavier, you might feel like the same convertible car seat cannot hold their weight anymore, so it is better to get one with a higher weight capacity right from the start, which will save you the trouble later on.

Similarly, if you want to purchase a new one because your child’s weight is exceeding the height limit, then you’re at the right place. Today I will talk about best car seat for child over 40 lbs which will keep even older children safe for as long as you’re driving.

So without any delay, let’s get started.

7 Top Best Child Over 40 Lbs Car Seats Comparisons

1. WAYB Pico Travel Car Seat With Carrying Bag

I am going to start the article with the first product which is WAYB Pico Travel Car Seat With Carrying Bag. This is a forwards facing 5 point harness that is even foldable.

This weighs only 8 pounds, making it very easy to handle while installing and very easy to carry around. This is the most portable product out of all, making it great if you frequently switch between cars.

Additionally, this convertible is made for children aged between 2-5. It can hold up to 50 lbs of weight, so even your 3, 4-year old could be placed without any issue.

Besides, the design is also pretty minimalist. This seat is also very comfortable for your four-year-old, and they will not complain about being stuck there. It can be installed in two ways. Top tethers, as well as LATCH straps, could be used.

Not to mention, if you have any issues trying to install this seat, then WAYB has installation tutorials for that purpose which you can find on their webpage.

Additionally, the seat is very compact, which helps in portability. It is so compact you can put it in a backpack if you want to. The narrow design makes it possible to fit three across in a car, which is great if you have more than one kid.

2. Britax Marathon ClickTight Convertible Car Seat

The next product is the Britax Marathon ClickTight Convertible Car Seat. This product has a really good weight capacity, so you can have your child seated in it for a long time as they grow.

The weight capacity is up to 65 pounds, which is great for four-year-olds or even older children. Moreover, this product also has had excellent performance in the third party and NHTSA car tests.

Furthermore, the safety tests have ensured that this convertible seat is perfectly safe for use and your child. The ClickTight system also makes it easy to install. This system also ensures that the seat is securely placed, which is very important. This is because many accidents and failures with these convertible seats happen.

After all, these haven’t been installed properly, so it is important to make that sure. The ClickTight System has a seat belt securing methodology. This will make it very easy to switch if you change cars frequently.

This system works like it’s a key. You have to twist it clockwise, which will tighten up the straps, and then secure the seat bottom after this. It is not like the usual system, but not hard to learn either.

This product will support up to 65 pounds in the front-facing position, so there will be no rear-facing for kids above 41 lbs. Additionally, it has 14 position harnesses and a two-position buckle which helps make this fit comfortably as your child grows.

7 recline positions are also included for the perfect fit. It has a layer of side impact protection and an impact-absorbing base and a steel frame. This makes the product extra safe for your baby to be in.

However, it can be hard with this car seat to take the baby out of the rear-facing position. However, as there is no rear-facing position for kids over 41 lbs, I am not concerned with that. This seat cannot be used for plane travel as well.
  • Good performance in-car tests
  • Easy to install
  • Seat belt securing methodology
  • 14 position harnesses
  • 7 recline positions
  • Hard to take the baby out of the rear-facing position

3. Safe Traffic System Ride Safer Travel Vest Gen 5

The Safe Traffic System Ride Safer Travel Vest Gen 5 is the next product I have. As booster seats are needed when a child turns four years old, there are a few problems that occur with these.

These are that they are heavy as well as cumbersome. This will make it very hard to switch these from one vehicle to the other when traveling if you do switch frequently. Therefore, a Travel Vest will solve the issue.

This is a great alternative made for children that are 3 – 5 years in age. The weight specifications are 30 – 60 pounds, and the height specifications are 35 to 48 inches.

This vest attaches to your seat from the back. The seat belt holders, in addition, will attach to the belt of the vehicle, which will make sure that the belt is placed properly around the body of your child. This product is crash and safety tested and has amazing performance.

Therefore your child will be really safe in case of any impacts or accidents, so you don’t have to worry about that. Besides, this product is legal in the US and also meets all the FMVSS 213 Federal Standards. Much more comfortable than the typical booster seats, this product is even much safer than those.

To place your child inside, you have to open the buckle as well as the Velcro panel placed in the front. Tell your child to slip their arms in and pull down the vest. Then after fasting the Velcro, if you need to adjust the strap, then do so.

Also, you can even fit three of these across in a car, which is great if you have multiple kids. This product is also adjustable and able to last many years. This is great as you won’t have to purchase another one for a long time.

However, this product cannot be used in the airplane, so you’ll have to find another solution for that. Otherwise this product is good to go.
  • Crash and safety tested
  • Meet all safety standards
  • Comfortable
  • Easy to place your child in

This ensures that your child will be completely safe in most conditions, which is a top priority when choosing a car seat. Moreover, the great part about this product is that it can stay rear-facing at a higher weight capacity, 50 pounds.

This makes it much better than the rest of the products in the market as most don’t have a rear-facing capacity that high. After buying this product once when your child is young, this one will last you really long, actually for years as your child grows, without ever needing to change it.

Lastly, this will help your child to ride the rear-facing longer much safely. According to customers, this convertible car seat gives so much legroom, and most users are very pleased with how comfortable this product is.

However, the belt installation with this product is kind of hard so you might have to check the belt installation before buying.

  • 50 pounds’ rear-facing weight capacity
  • No-rethread headrest and harness
  • Additional 5 inches legroom
