Great seat all around!
This review was collected as part of a promotion
This car seat is fantastic. It's easy to install, and my taller toddler is noticeably more comfortable when getting buckled in. He loves the footrest, and we love that the seat will grow with him for years to come. Highly recommend!

Easy to Use Seat
This review was collected as part of a promotion
The functionality of this seat is really nice and the slim profile is great for fitting 3 across in the back seat even with the cup holders attached. It's easy to install, and very easy to adjust. We really like the quick latch on the chest clip, unfortunately it's so easy to unlatch that our kid unclips the chest clip when she's being naughty. My primary reason for giving it 4 stars instead of 5 is that it isn't offered with a flame-retardent free fabric.

Best Baby Product We’ve Bought
This is honestly the best baby product ever and by far the most-used item we’ve had! We’ve used it since my daughter was a newborn, and we’re still using it every day with her at 5 months old. It’s been the perfect changing station and bassinet, and as she gets a little older, we’ll be able to use the Pack ’n Play portion as well. I love that it grows with her and can be used for so many different things.
It was also very easy to put together, which is a huge plus! Overall, this is such…

Easy installation and my seat backs stay clean
This review was collected as part of a promotion
The rigid LATCH system is the star here. No wrestling with straps, just click it into the anchors and it's locked in with zero wiggle. Install takes seconds and feels genuinely secure.
The footrest is a sneaky-great feature. My daughter's feet now rest on it instead of drumming against the back of my seat, which alone was amazing.
Build quality is a step above what I expected too. Every button, adjuster, and latch has a solid, reassuring click, and nothing feels flimsy or plasticky.…

Overall thrilled with this play yard
This review was collected as part of a promotion
I have had this play yard for a month with my newest little guy and it has been so easy to use! I wish I had this with my previous three children. It's well designed and sturdy. I think it will last a long time. I also love that it is attractive in my home.

Latch system and foot rest is amazing!
This review was collected as part of a promotion
Really happy with this seat. The fabric is cooling and easy to clean. The straps operate effortlessly, foot rest is genius so my kid stops kicking the back of my seat, and the latch system/install is a total game changer. No more fighting buckles or cutting your finger like our previous seats.

Excellent Car Seat!
This review was collected as part of a promotion
We’ve been really happy with this car seat! The latch feature makes installation so easy and gives peace of mind that the seat is securely installed. It’s also very comfortable and has plenty of padding and support, which is great for longer car rides.
I love all of the little accessories and thoughtful features, too. The cup holder & footrest is incredibly convenient, and everything feels well-designed and easy to use. All the designs are thoughtful, like the padding around the bottom…

Great features!
This review was collected as part of a promotion
We are so happy with the Joie bay latch SI plus! We have four kids under five and have tried several brands of car seats. This one is by far our favorite for the value and the it looking great is a nice bonus! It is also slightly smaller than some of our other conversion car seats so we like traveling with it.
