Britax Marathon ClickTight Convertible Car Seat

81EnRvKOZIL. SL1500

Best Pick

It’s one of my favorite car seat In terms of installation, it could not be easier. My recommendation is to remove almost all the slack in your seatbelt–leave just a little. We had to figure it out a little the first time we installed it because if you don’t tighten up the slack, installation goes sideways. You can play around for about 10 minutes the first time, so take your time.

Cosco Apt 50 Convertible Car Seat 

9154EjdXLlL. SL1500

Due to its single piece of injection-moulded plastic construction, this car seat is extremely light. For forward-facing, it includes a strap that goes over the top of the seat and a single latch strap that works for both front and rear. That’s all there is to it, four parts.

It is not a federally approved car seat, but it is a lot safer than our Graco 4ever car seat, which has 30 parts and weighs four times as much. The fact that our son is rear-facing at two years old also helps a lot with safety.

Cosco APT 50 Installation

I cannot comment on the capabilities of forward-facing since our son is still rear-facing. FAA-approved and super light, it makes traveling easy. Though we didn’t end up using it on our flight, it was convenient.

The bottom line is that everyone should have a backup car seat. Installation is also accessible and takes a few minutes. After a trip, we just put the cover in the washing machine. We don’t even bother putting it in a “car seat bag.” wash it after a trip.

What should be considered while buying the best lightweight convertible car seat

  • The car seat should be lightweight.

A travel car seat must be lightweight as an essential attribute.

The convertible car seat will have to be removed from the car, moved around the airport, passed through security, on and off the airplane, and into another car – so things might go wrong if it is bulky. With lightweight car seats, you can change all that. 

If you add the baby’s weight, these car seats shouldn’t be problematic in terms of weight (plus minus a pound or two). Only when they are used in cars do you not have to worry about it.

If you don’t know where you will be going, it’s better to get the all-in-one.

  • Car seats should be easy to install

It’s crucial to install these car seats in unfamiliar vehicles since you’ll take them in and out of them.

A cranky and crying kid after a long flight is the last thing you want (this was me two years ago in NYC). Please, don’t do that to yourself!

In the infant car seat mode, a convertible car seat might require that it be installed reclining. Some car seats may have curved bases or flip-down feet; however, others might require pool noodles. 

LATCH attachments and connectors are available on most American car seats for simple installation. In the end, all the LATCH locking clips will work. Some require more maneuvering than others.

  • Dimension of convertible car seat

A car seat’s size is also essential since you have to make sure the back and head of the child can fit comfortably.

Rear-facing styles require the heads to be one inch above the shell, and forward-facing styles require the heads to be inside the body.

The size you choose depends on your needs, as there is no ideal size.

A car’s shell is critical in accommodating taller kids, while sharp shells are lighter and fit better in rental cars or airplane seats.

The safest convertible car seat for travel

Probably the most subjective of all factors is this last one. Nevertheless, you do not want your child to be cranky on a long-haul flight! The plastic shell of some traveling car seats doesn’t have any padding. The seats will not matter too much if you just use them on the plane and then a quick taxi ride afterward. However, if you’re planning to sit there every day or take a road trip to your destination, you don’t want to hear a complaint every five minutes.
