Horrible install not safe!!
Not only is this seat nearly impossible to get a secure install, it does not even FEEL safe. We’re a busy family and moving this seat from car to car makes my anxiety worse!! I’m not sure how this seat passes any safety standards.

Easy to Install and Versatile as Kids Grow
This seat is easy to install and allows for a lot more passenger room. It is a great transition from a forward facing seat to a booster.

Perfect for a 4 year old now, and to grow into.
We were looking for a transitional seat for our 4 year old granddaughter, because her brother had outgrown his infant seat/stroller and needed to move up to hers. She's on the lighter side, and this model is great. Its easy to install and use, comfortable for her, and looks good too (we purchased black).

Car seats for grandsons
Bought for twins. My grandsons needed a comfortable car seat with two cup holders. Easy to install and easy to get them in and out.

Best Jeep Owners Car Seat
I absolutely love the car seat! It’s not bulky and the color is very demure! My toddler loves it and falls asleep comfortably. The straps adjust easily, it was very easy to set it up in the car. I look forward to adjusting it to the booster level for when she gets older. I recommend this car seat for all Jeep owners.

Saved my sons life
This car seat is basic yet safe! We were in a car accident where we rolled twice. My son had not a scratch or bruise. We love how simple it is to use and how slim it is. The cup holders come off easily and it does slide a little even after we strap it in (which is why I gave it four stars). But overall it’s great and it saved my son. Also love how light it is esp when w...

Forward-facing car seat
This car seat has been great for our 3.5 yr old who we transitioned to forward-facing. It is very easy to install and uninstall, and lightweight to move from vehicle to vehicle with ease. Having multiple color options was an added bonus.

Affordable, safe, light weight option
I purchased this seat because my child grew out of their infant seat. We love it, it’s light weight but still feels safe. We’re loving it.

grace is the way to go
of course i had to purchase two because i have twins..
the assembly was easy as popping it together
the installation was just as easy as the assembly.
storage will be easy if we ever need it
they have great effectiveness and get the job done especially for two 5 year olds
the durability is amazing when you have a rough and tough kid!

Excellent car seat
Very stable installation with LATCH and tether, very low profile so still lots of room, no kicking the back of the seat. It's roomy and comfortable but straps very secure and easy to get 2 year old in and out. Great value, very happy with it.
