As a parent, ensuring the safety and comfort of our precious cargo is always a top priority. And if you happen to own a Tesla Model X, you know that finding the right car seats that fit perfectly and offer maximum safety and convenience is not easy. 

That’s why I’ve spent a significant amount of time researching and reading car seat manuals, reviews, and other resources to find car seats that are narrow, easy to install, and have the potential to work well with a 3-across installation in the Tesla Model X.

 So here are my top picks for the best car seats for Tesla Model X.

Important note: These car seats can work with different models of the Tesla Model X (5, 6, 7 seater models), but it’s crucial to read both the car and the car seat manual to ensure a safe installation

5 Best Car Seats For Tesla Model X

Clek Liing (Best Infant Car Seat For Tesla Model X)

Dimensions: ‎ D22.6” x W16.9” x H26.8”

Weight limits: Rear-facing (4-35 lbs)

Weight‎: 9 lbs

The Clek Liing weighs 9 pounds and measures only 16.9 inches wide which makes it the narrowest infant car seat on the market. 

So, if you plan a 3 across install with an infant seat in the Tesla Model X, it should be the Clek Liing.  

The Liing comes with an adjustable recline with 7 positions for the perfect angle, and a rigid LATCH system for easy installation with Tesla’s outboard seat anchors. 

The Clek Liing also offers a ​​belt-tensioning system that you can use for the middle seat with no LATCH.

The energy-absorbing load leg offers added stability to the car seat and reduce the risk of injury to your child in a crash. 

When using an adapter, the Liing is compatible with several strollers including the Mockingbird, Baby Jogger, Bugaboo, Stokke, Thule, and UPPAbaby. 

Plus, the Clek brand is known for its sleek and high-end finished car seats that are flame retardant free, and of course, the Clek Liing is no different.

Graco Slimfit3 LX (Best Convertible Car Seat For Tesla Model X) 

best car seat for Tesla Model X Graco slimfit3 lx

Dimensions: ‎ D20” x W16.5” x H24.5” 

Weight limits: Rear-facing (5-40 lb), Forward-facing (22-65 lb), Highback booster (40-100 lb)

Weight‎: 19.2 lbs

We always recommend the Slimfi3 LX as a suitable convertible car seat for 3 across in small cars like Tesla

What sets the Slimfit3 LX apart from other narrow car seats is that it’s a 3-in-1. Other narrow car seats that are suitable for 3 across are convertibles with no Booster.

The Slimfit3 LX can accommodate your child from 5 pounds until they are old enough for a booster. So, it may be the only seat you will ever buy. 

To get the best 3 across installed in your Tesla Model X with this car seat, you must use the seatbelt instead of LATCH (for all 3 car seats). This will give you more flexibility to adjust the spacing between all 3 car seats. 

Overall, the Slimfit3 LX is a solid and safe all-in-one car seat from Graco. It features a steel frame, LATCH and seatbelt installation options, a removable cover that can be machine washed, and removal cup holders as well. 

Note: You must confuse the Slimfit3 LX with the original Slimfit 3 in 1. The Slimfit3 LX also called the True3fit in Walmart is 2 inches narrower than the regular Slimfit 3 in 1.

Peg Perego Viaggio 2-3 Shuttle Plus (Best Booster Car Seat For Tesla Model X )

Dimensions: ‎ W17″ x D17″ x H26″

Weight limits: Forward-facing (40-120 lbs)

Weight‎: 14 lbs

The Peg Perego Viaggio Shuttle is a great booster seat. It’s narrow, super lightweight, and easy to install. Even kids can set it up with no help. 

With its removable backrest, you can easily switch from a high back booster to a backless one when your child is ready.

And we really enjoyed learning about the Shuttle Plus 3D total adjust feature that allows you to adjust the headrest, the upper backrest, and the side wings independently.

This amazing feature makes the car seat suitable for all booster-aged kids of different sizes and heights. And since it accommodates kids up to 120 pounds, the car seat can be used for a long time as the child grows and develops.

We also noticed that the Peg Pergo Shuttle Plus is roomier than other boosters thanks to its narrow armrest. 

On the flip side, the Peg Perego Viaggio Plus 120 is very expensive. However, you really get what you pay for.

Diono Radian 3RXT (Best for Forward Facing In Tesla Model X)

diono radian 3rxt narrow seat for Tesla Model X

Dimensions: ‎ D16” x W17” x H28.5”

Weight limits: Rea-facing (5-50), Forward-facing (50-120)

Weight‎: 28.1 lbs

If you are planning to have more than one car seat in your Tesla Model X, the Diono Radian 3RXT works well with that. 

The extremely low profile and narrow design of the Diono fit great near other car seats.

The Radian 3RXT features shallow sides, which makes it easy for the kids to get in and out of the seat, especially when it’s installed in the center. 

We recommend the Radian 3RXT only as a forward-facing car seat in the Tesla Model X. When rear-facing, it’s extremely hard to get a tight fit using a seatbelt install. 

What about LATCH installation? Yes, you can use LATCH with Diono Radian 3RXT but it has a very short limit of 35 pounds when installed with LATCH rear-facing. 

Other than that the Diono Radian 3RXT is a solid car seat with tons of safety and comfort features, plus a narrow design that can save you space inside your Tesla. 

Other key-selling features

Steel reinforced frame

Easy-adjust 12 positions

3 across design

Not recommended for rear-facing

Clek Foonf (Best Toxins Free Car Seat For Tesla Model X)

clek foonf convertible car seat for Tesla X

Dimensions: ‎ D17.5″ x W16.9″ x H28″

Weight limits: Rear-facing (14-50 lbs), Forward-facing (22-65 lbs)

Weight‎: 38 lbs

The Clek Foonf with the C-Zero Plus Performance is free of halogenated flame retardants. It uses naturally flame-retardant fabrics. This makes the Foonf a great toxins-free car seat for your Tesla.  

We chose the Foonf not just because it lacks flame retardants but also due to its slim design that works well with 3 across.

In addition to being safe from harmful chemicals and narrow, the Foonf ensures a super-tight installation in your car. Why? Because the Clek Foonf uses rigid LATCH for forward-facing installation.

We all love LATCH installation, it’s a lot easier than seatbelt installation. However, this prevents the Clek Foonf from being installed in the center seat in most cars including the Tesla Model X where there are no LATCH anchors.

While the Clek Foonf is on the pricey side, we think it’s worth the investment because it features great safety features, uses quality materials, and comfortable for your child.
