Description
This Car Seat grows with little ones from 4-120 lbs, providing up to ten years of use. The 4-in-1 car seat transitions from a rear-facing harness (4-40 lbs) to forward-facing harness (26.5-65 lbs) to highback belt-positioning booster (40-100 lbs) to a backless booster (40-120 lbs).
The slim, space-saving design still gives kiddos plenty of room to grow (it has a 10% slimmer design at the cup holders than 4Ever DLX to save precious back seat space).
The easy installation SnugLock technology works in rear and forward-facing modes to get your seat installed in less than one minute using the vehicle seat belt or LATCH.
The No-Rethread Simply Safe Adjust Harness System allows you to adjust the height of the headrest and harness in one motion for just the right fit. The push-button InRight LATCH, which provides an easy, one-second attachment with an audible click to help ensure secure installation.
The six-position recline smoothly adjusts to help with installation, while the Rapid Remove cover is machine-washable for easy cleanup. Fuss-free harness storage holds the harness out of the way for easier ins and outs.
Removable plush head and body inserts help to keep baby feeling cradled and comfortable. Steel-reinforced frame provides strength and durability for years of use.
The car seat is Graco ProtectPlus Engineered to help protect in frontal, side, rear and rollover crashes.

Great car seat that fits three wide. It seems to be comfortable and fits from newborn through car seat life. All four of my kids are in DLX seats, and loved to have the slim option!

I don’t think you should base your car seat decision on a review, but this is the best car seat so far. It’s slim and our baby feels so comfy . We look for a car seat that was slimmer than current one. We picked this one based on a. recommendation for a car seat safety expert. It was harder to fit in and get right with the lower latches, but once we got it, it was perfect. Even though our baby is tall, she can even reach the cupholders. Our toddler had a hard time in her car seat at first.

Great seat, tricky install
This review was collected as part of a promotion
Overall very happy with this car seat. It feels sturdy and secure once installed and our child is comfortable in it. That said, installation was not very intuitive at first. We had to watch several YouTube videos to make sure we were doing it correctly. Once installed, it’s great, just be prepared for a bit of a learning curve.

No more EZ tight Latch
This review was collected as part of a promotion
Purchased to replace my Graco 4Ever DLX Platinum after an accident. Love it but they no longer have the EZ Tight Latch, which is honestly the only reason I originally chose this seat. That was hands down the best feature and I probably won't repurchase because it isn't available anymore.

Good car seat but takes a bit to get use to
This review was collected as part of a promotion
The push buttons to undo can be a bit hard to unbuckle and to tighten is a little tougher, not as smooth as our previous car seat. But overall very pleased, just took sometime to get use to.

A True 3 Across Seat!
This review was collected as part of a promotion
This is great for small cars!!! I have two of these and a graco snugfit carrier in the back seat of a Buick Verono. It’s reasonably comfortable and I love that the cup holders are detachable. I do recommend going to the fire department to ensure you have it installed correctly if you have 3 seats across though.
