Families with three or more children struggle to fit more than two booster seats in their vehicle, especially if they prefer a smaller car. Most car seats and booster seats are too wide, so you’re limited when it comes to narrow booster seats. Luckily, there are some products on the market that will fit the bill for a narrow booster seat.

Brand Width Weight Limits
Evenflo Big Kid Booster Seat 16 inches 40 to 120 pounds
Peg Perego Viaggio HBB 120 16 inches 40 to 120 pounds
Safety 1st Boost Air 16 inches 30 to 100 pounds
Clek Oobr High Back Booster Car Seat 15.5 inches 33 to 100 pounds
Chicco KidFIt Booster Car Seat 17 inches 30 to 100 pounds

Is My Child Ready for a Booster Seat?

Before you get the narrow booster seat, you have to make sure your child is ready for this type of seat. Kids are safer in a 5-point harness, so don’t rush to put your child in a booster seat. Children need to ride in a booster seat until they can pass the 5-step test, usually between 10 and 12 years old.

If your child meets all of these guidelines, your child is ready for a booster seat.

  • The vehicle has a shoulder and a lap belt because boosters require a shoulder belt.
  • The child is at least 4 years old.
  • He weighs at least 40 pounds.
  • Your child can sit properly the entire time without leaning forward, slouching, sitting on their knees, playing with their belt, etc.

Picking The Best Narrow Booster Seats

When you’re picking a new booster seat, you have two models to consider:

  • High-Back Booster
    A high-back booster is a transition between a harnessed car seat and a booster seat with a seat belt. This style works for children 4 to 6 years old. It helps the child get used to using a seat belt, and they typically have seat belt paths that help ensure the belt is placed correctly on your child. If your child is exceeding the height and weight requirements of their current forward-facing car seat, a high-back booster is a good choice.
  • Backless Booster
    The backless booster is a simple booster seat that just has the bottom portion without a back or a seat belt path. This booster style usually has armrests and a drink holder or two. Backless boosters are better for kids between 6 and 9 years old who are large enough to not require a seat belt path and are mature enough to sit straight upwards.

Once you have the right model, you have a few features to consider, such as:

  • Width
    Since you’re looking for a narrow booster seat, the width is going to be a factor. For this list, all of the boosters are 17-inches at the base or narrower. If you go much wider, it’ll be too hard to buckle the car seats in place when there are three child.
  • Price
    Price is always a concern! Some of these booster seats are less than $50 and some are above $200, so there is a choice for everyone no matter what you can afford. Remember that price doesn’t mean that your child isn’t as safe as a child in a more expensive seat. All car seats must meet the same safety regulations. The price will change based on the quality of the fabric, plushness, and extra features that other seats may or may not offer.
  • Safety
    The purpose of a booster seat is to keep your child safe, so no other feature matters if it can’t keep your child safe. High-back boosters should have a stabilizer like a steel frame that helps to absorb the energy during an impact.

    A backless booster needs to have a way to allow the vehicle’s seat belt to secure the child to the seat. You might want a seat that has a clip that attaches to the vehicle’s seat belt to keep it properly positioned on your child’s seat.

  • Washability
    Kids are messy; that’s just the truth. If you allow your kids to eat in the car, you’re going to have crumbs and stains. Even if your child doesn’t eat in the car, accidents happen, so it’s best to pick a seat that is easily washed.Spot-wash only can be a pain. Many parents prefer to have car seats that let you remove the booster seat cover and toss it in the washing machine.

Safety 1st is another great choice that won’t break the bank yet offers everything that you could want in a narrow booster seat.

4. Clek Oobr High Back Booster Car Seat

Clek Oobr High Back Booster Car SeatView on Amazon

Clek sells some of the best car seats on the market, and their Clek Oobr booster car seat is a good pick for a narrow booster seat. At first glance, you might think that it might be wider, but the booster only measures 15.5 inches wide at its base. The base is what matters the most when trying to fit multiple booster seats across your vehicle’s seat.

At the armrests, it does stick out a bit, around 18 inches wide, but the narrow base gives you plenty of space to put your hand between the car seats to buckle the seat belts. If you’re putting three forward-facing car seats together, the armrests might make this a bit too wide, but it works great if you have any rear-facing seats.

Parents love the sleek, modern, yet simple, style. The Oobr uses the LATCH system for keeping the seat in place, and it will convert from a high-back booster to a backless booster seat. The high-ba1ck booster works for kids 33-100 pounds and up to 57-inches tall, and the backless booster is for kids 40-100 pounds and up to 57-inches tall.

For safety, Clek uses a reinforced frame, energy-absorbing foam, and a headrest with side impact protection. It also has an adjustable recline that’s easy to use, and the fabric is GreenGuard Certified, which means Clek didn’t use any toxic chemicals.

Of course, there are a few negatives to consider. The headrest leaves a gap when you lift it up, exposing just metal bars. It’s also quite expensive, about the price of a combination car seat, but it is a narrow booster seat that works great for years.

Only 15.5 inches wide
Modern, sleek design
Uses the LATCH system
Adjustable reclining seat
GreenGuard Certified fabric
The headrest has a gap exposing metal bars

5. Chicco KidFIt Booster Car Seat

If you need a booster seat that is narrow at the base and throughout the armrest area, the Chicco KidFit measures around 17-inches wide at the base. The shoulders spread out to around 19-inches wide at the maximum width. This seat should work for situations that put the booster seat next to a rear-facing car seat or a backless booster seat.

Chicco added all of the features that parents could want in a booster car seat. It has an up-front LATCH adjustment that’s easy to use. You can use it for kids 30-100 pounds. Unlike other boosters, the KidFi offers 10 different height positions, so you can find the right fit for your child. Plus, the headrest is easy to adjust, and it adjusts the height of the entire back which is good for seat belt position.

Parents love the plush and nice fabric, and the seat can recline in a variety of vehicles. To help reduce the width of the booster seat, Chicco added collapsible cup holders, which make the seat even narrow than other choices. You can convert the KidFit from a high-back booster to a backless booster seat.

One thing to note is that the belt-positioners don’t do the best job at holding the seat belt in place. It can pop out of the track.
