SlimFit™ All-in-One Car Seats

Smart Safety for Tight Spaces

If you’ve ever struggled to install three car seats side by side, the SlimFit™ collection is here to help. Families with multiple children will appreciate having narrow booster seats and convertible options that truly make the most of limited back seat space. Each design not only keeps your child secure, but also gives your family the freedom to travel together more comfortably, turning cramped car rides into calmer journeys.
Graco® engineers understand that busy parents deserve more than just safety. They also need car seats that make everyday life feel simpler and smoother. With narrow car seats to fit 3 in a row, you can create the layout that works best for your family, whether that means three little ones seated side by side or a mix of toddlers and older siblings.

Built to Grow with Your Child
SlimFit™ All-in-One Car Seats combine three seating modes in one, giving families a solution that lasts for years of growth. Instead of buying multiple seats, one SlimFit™ grows right along with your child.

• Rear-Facing Harness (5–40 lbs): A snug, protective embrace for infants and younger toddlers.
• Forward-Facing Harness (22–65 lbs or 26.5–65 lbs depending on model): Steady, dependable protection as your child grows curious and independent.
• Highback Booster (40–100 lbs): A slim yet supportive booster seat, keeping older children safe and comfortable on longer adventures.

This 3-in-1 functionality means fewer transitions between car seats, saving parents both money and stress.

Easy Installation, Easy Cleaning
Installing a car seat shouldn’t feel like a battle. That’s why SlimFit™ models are built with parent-friendly touches that make the process easier:

• Simply Safe Adjust™ Harness System: Adjusts headrest and harness together in seconds.
• Rapid Remove Covers: Take off the cover in under 60 seconds, without uninstalling the seat.
• Integrated Cup Holders: Rotate away when not in use, creating a slimmer profile and easier access for kids.

The LX model even includes myPocket™ storage, perfect for stashing small toys, or travel treasures within arm’s reach.
