Can You Use a Carseat Without the Base?

Hey there, fellow parents!

Are you tired of lugging around a heavy car seat base every time you travel with your little one? As a mom of three and a frequent traveler, I know the struggle all too well. But fear not! I’m here to answer the burning question on every parent’s mind: Can you use a car seat without the base?


The base that comes with the car seat is nothing but a convenience feature. You install it in your car and simply snap the carrier in every time you head out.

If you’re a frequent flyer or ride-share service user, a car seat you can install without a base is a blessing. You don’t want to lug a convertible car seat around. It’s heavy, chunky, and a tad complicated.

Luckily, you can use any car seat without a base for traveling, and I’ll teach you how.

Warning: You might just become addicted to exploring new places with your child once we’re done here.

Let’s get to it already!

Using Car Seat Without Base

There are two ways to secure a car seat without a base using the seatbelt: the American belt path and the European belt path.

In both types, you hook the lap portion of the seatbelt from the slots on the carrier’s lap area. The difference is the belt guide at the back of the car seat on the European one.

Mano a mano, this feature makes the latter the runaway winner. If you’re not convinced, check out the benefits of a European belt path:

  • It provides a tighter and more secure
  • It’s safer because it gives the baby’s head and neck more protection in a crash.
  • Unlike the American method, you can use it anywhere outside the US, where cars don’t have a seatbelt locking mechanism.

How to Install Car Seat Without Base

Let’s walk you through the steps of installing a car seat without a base.

Using the American Belt Path

  1. Position your rear-facing car seat on the backseat. Never place it on the front seat, directly in the airbag’s path.
  2. Take the seatbelt and run the lap portion through the guides on the car seat.
  3. Buckle the seatbelt.
  4. Engage the shoulder belt’s locking mechanism. To do this, slowly pull down the shoulder belt to the very end. Then let it retract and keep an ear out for the click-click-click sound.
  5. Tug on the shoulder belt gently to check if it’s in locking mode. If you feel it can’t get slack, give yourself a pat on the back.
  6. Recline the car seat properly before tightening it. Most car seats have a line or marker on the side to guide alignment.

Now, on to the second phase. You want the car seat snug and secure, so follow this guide: 

  1. Stand behind the car seat. Slide the front seat forward to give you more room.
  2. Anchor the top of the car seat on your thighs while keeping your knees straight. This way, you don’t lift the car seat when crouching down.
  3. Slip your hands through the car seat’s handle and grab the shoulder belt, pulling it towards you.
  4. Push the car seat into the back with your thighs and wiggle it from side to side.
  5. Feed all the slack of the shoulder belt into the retractor.
  6. Rock the car seat from the side. It shouldn’t move an inch or more when you do this.

If you can’t fit behind the car seat, you can tighten it from the side by doing these steps:

  1. Place one knee on the cushion opposite the seatbelt buckle and the other behind the car seat.
  2. Pull the shoulder belt with your hand closer to the buckle and use the other hand to apply weight on both sides of the baby’s elbow alternately.
  3. While holding the shoulder belt, continue pushing the car seat back and forth until the lap portion is snug.
  4. Repeat steps 5 and 6 from the guide above.

Using the European Belt Path

You can install the European path using the American method with just one extra step.

Once you’ve properly reclined the car seat, loop the shoulder belt around the back and into the designated guide. For a tightness check, ensure the car seat has less than an inch of wiggle room

Best Car Seat Without Base

Of course, the best car seats without a base are those with the European belt path. I’ve rounded up the cream of the crop of infant seats with this nifty feature:

  • Chicco Fit2
  • Doona Infant Car Seat
  • Peg Perego Primo Viaggio 4-35 Nido
  • Britax B-Safe Gen2 FlexFit
  • Graco Classic Connect SnugRide 35

Roger and out!
