[amazon link=”B01N3MYVZM” title=”Best All-in-One Car Seat: Graco SlimFit” /]

[amazon box=”B01N3MYVZM”]

All-in-one car seats are a popular choice because of how convenient it is to only buy one car seat for your child. However, all-in-one car seats can take up a lot of space, which can be challenging if you have a compact car. Luckily, Graco made the SlimFit, which is just under 20 inches wide, has adjustable cup holders and can be used by your child until he or she has outgrown car seats completely. Plus, it’s around $170.


  • Affordable for an all-in-one car seat

[amazon link=”B013YCWASA” title=”Best Compact Car Seat for Toddlers: Britax Boulevard ClickTight” /]

[amazon box=”B013YCWASA”]

Your toddler is only getting bigger, but his or her car seat doesn’t need to. This convertible car seat is only 18.5 inches wide and can accommodate children from five pounds to 65 pounds. Your child will be kept safe with this car seat’s SafeCell Impact Protection features, which include an energy-absorbing base, advanced tethering and stitching, and a steel frame. Plus, it lets you know if your child’s harness is tight enough with an audible click. Britax’s ClickTight technology allows you to use your car’s seat belt, which is safer than the LATCH system many other car seats use.

[amazon link=”B076PS61XS” title=”Best Compact Car Seat for Tall Toddlers: Diono Radian RXT” /]

[amazon box=”B076PS61XS”]

If you are looking for a compact car seat that will fit your tall toddler, then you don’t need to look any farther. The Diono Radian RXT is an all-in-one car seat that can fit rear-facing toddlers as tall as 44 inches and front-facing toddlers as tall as 57 inches. Since most car seats can’t accommodate children over 49 inches, the Diono Radian is exceptionally well-designed for tall children. Even though this car seat is plenty tall, it is still very narrow. At only 17 inches wide, this car seat will take up hardly any room in your car.


  • Can fit very tall toddlers
  • Only 17 inches wide


  • Diono Rainier is a better model for only $10 more

[amazon link=”B076PQVCF1″ title=”Best Compact Car Seat for Heavy Toddlers: Diono Rainier” /]

[amazon box=”B076PQVCF1″]

The Diono Rainier is almost identical to the Diono Radian with a couple of significant differences. First, the Diono Rainier has additional sidewalls that are extra deep and lined with energy-absorbing foam to provide more protection to your child’s head. Although this is a great safety feature, this causes the top section of the car seat to be 1.5 inches wider than the Radian. Compared to the Radian that can support 45 pounds when rear-facing and 80 pounds when front-facing, the Rainer can support up to 50 pounds and up to 90 pounds, respectively.


  • Extra protection
  • Can support even higher weight limits in both rear and front-facing


  • Sidewalls makes this car seat wider
  • Expensive model
