Product Description

The Graco® SlimFit3™ LX 3-in-1 Car Seat is our slimmest design that fits 3 car seats across, saving space in your back seat without compromising on the safety you trust and the features you need. This narrow all-in-one car seat grows with your child from rear-facing harness (5-40 lb) to forward-facing harness (22-65 lb) to highback booster (40-100 lb). We tested our lightweight 3-across car seat in every configuration, to help ensure your growing family can fit in your vehicle, even with children of different ages who ride in different modes, or when paired with select other Graco car seats. Integrated belt lock-off makes for easy vehicle seat belt installation in forward-facing mode, and allows you to position your seats to maximize space with 3 across. Graco’s exclusive push-button InRight™ LATCH provides an easy, one-second attachment with an audible click to help ensure secure installation. We made thoughtful design choices to make the SlimFit3 easy to adjust with 3 car seats in the back seat. The No-Rethread Simply Safe Adjust™ Harness System allows you to adjust the height of the headrest and harness to 10 positions with just one motion for just the right fit. Easily adjust the 4-position recline for a better installation and a comfortable ride. The Rapid Remove cover comes off in 60 seconds, without uninstalling the seat or removing the harness, and is machine washable. Plus, the SlimFit3™ is slim enough to fit 3 across, but spacious enough to keep your growing child comfy. Breathable mesh AirFlow channels provide improved ventilation to keep your child cool and comfortable. Two cup holders are designed to work with the three-across configuration to keep drinks and snacks close at hand. Fuss-free harness storage pockets conveniently hold the harness out of the way while your child gets in and out. Removable, plush head and body inserts help to keep your infant feeling cradled and comfortable. The steel-reinforced frame provides strength and durability for years of use, and EPS energy-absorbing foam provides effective impact energy management. This car seat is Graco® ProtectPlus Engineered™ to help protect in frontal, side, rear, and rollover crashes.

Initial thought - I don't need another vehicle, fits 2nd Gen Access Cab Tacoma.
I've been tossing the idea out about getting a new vehicle just so I can fit a car seat, we only had one car that fit our car seat, but that's not ideal in case of emergencies. It seemed everyone on the internet said a car seat just won't fit in my truck, to go buy another vehicle. After some research, I stumbled upon this car seat. I am glad I bought it, because it does fit in my 2007 Toyota Tacoma Access cab. Granted, its a tight fit, probably not ideal for long car rides, but perfect for around the corner trips, exactly what I needed. I can't speak on the rear facing position, but the forward facing position works for my needs. Time will tell on the booster seat configuration. I was also happy that the manufacturer date was only three months ago, some reviews on car seats state they got old dated seats. Installation was not too difficult, once I figured out where to attach everything on my truck. I love the easily adjustable shoulder straps, makes it easier to adjust as our child grows.

    As a Child Passenger Safety Technician, I LOVE THIS SEAT! It's slim, SO easy to install, safe, and takes the place of 3 seats. (rear facing and forward facing booster, as well as a belt positioning booster) It grows with baby so my daughter will be in this seat for several years! Excellent value!

    This car seat is amazing. It doesn’t get my kid overheated. It seems to be breathing. It is slim in the car and an airplane. It is a little heavier than I would like, but I have to think that you make car seats heavier so that they are safe and I love the fact that it grows with my kids. If you are using the anchor systems in your car. This thing is insanely easy comparative to other car seats. And you can take the covers off they wash fairly easily and you do not need to be a rocket scientist or a contortionist to get the thing back on the base of the car seat.

    Size: SlimFitColor: AnnabelleVerified Purchase
    I bought this carseat when my little one outgrew her infant seat. I drive a prius and every centimeter of space counts! I actually think 3 of these might fit across my tiny backseat. I have a huge baby (think 3 year old at half the age) and this still has plenty of space to grow with her.

    Pros -
    - Comfort! My little one has never complained or seemingly suffered from a sore bum, even with 4 hours on the road. The seat is very plush and the thick head pads grow with your kiddo.
    - Cup hoooolders! It's right there, folks. And they fold in. I have found the cup holders fit every brand of sippy I have.
    - Easy installation. I had no idea how to install this thing (we're out of the realm of bases and clicking in now) and still managed to have it secured and adjusted in like 5 minutes.
    - Easy adjustments. So easy. I literally transitioned from rear to forward facing halfway through a trip. It was quick and easy. The headrest is the easiest to adjust, while the base acts allows you to adjust the recline of the seat.
    - Easy cleanup. I've found crumbs don't tend to get under the holes for straps, and I can just brush out or vacuum food bits. I've had two liquid food spills and baby wipes took the stains right up. Supposedly the fabric can be removed and washed, but I can't vouch for that or the process.
    - Has multiple install methods. Like the Graco infant seat I had before it, this car seat works with every kind of seat belt and the latch system.

    Cons -
    - This is not for infants. It advertises being good at 5 lbs, but my daughter would've been utterly eaten by this thing with space for rolling around at that size. I definitely recommend an infant seat first.
    - It's tall. The base that allows it to go between angles adds a little bit of height. It's not really noticeable, but items dropped are out of reach of the child. May be a pro depending on what's in your backseat.
    - The recline angles can be tricky. I could never get the rear facing to sit at the angle the seat wanted (it has the leveling tool built in), and now that it's forward facing it reads that it's perfect for rear facing. I'm left just going ????. My daughter seems comfortable so bah on it.

    That's it. I'm blessed enough to not know how it holds up in a car accident but I am confident in its ability to keep my lil one safe. Unless you see an update to my review in a few years stating otherwise, this is the carseat I'll have until my little one outgrows all seats and boosters.

    The install of this car seat is really easy, the instructions are super clear and easy to understand. It’s nicely padded. Adjusting the strap height is a little tricky, but that my only complaint about it. Also it is a slim fit car seat but definitely is going to take up some room in that back seat.

    Moved my big 5 1/2 month old out of her infant car seat into her big girl car seat and it’s been great! She seems so comfortable in this seat. The install was very easy using the anchors in the car. This car seat is a less tighter fit behind the passenger seat than her infant car seat was which shocked me.
    After doing much research on many different brands of car seats I chose this one because of the affordable price + the high crash safety ratings (which is very important to me).

    The car seat feels well built and solid. It’s also easy to carry my child in and out the seat.

    One thing probably to improve is that for front facing , should consider an additional tilt level. Now my boys take a nap instead of lying back, the whole body lean forward cause it’s too straight.
