A convertible car seat that can be used rear-facing and forward-facing
After the baby can sit unassisted or after the infant seat has been outgrown

Quirks to be aware of
Similarly named seats
In the world of car seats, it’s important to be aware of similar-sounding models. Apart from the Graco SlimFit3 LX, which is a narrow option, Graco also offers the Graco Slimfit 3 and Graco Slimfit 3 LX, neither of which boasts the same narrow design. These alternatives measure about 19 inches in width, making them wider choices. It’s also crucial to double-check the specific model you’re considering to ensure it aligns with your space requirements. Additionally, keep in mind that Graco True3Fit, a Walmart exclusive, is essentially the same as the slim Graco SlimFit3 LX, offering a narrow profile suitable for fitting multiple car seats in your vehicle comfortably.
