It features two removable cup holders to keep your child happy, and a machine washable seat pad, body insert, and harness covers.

Recommended Use
Forward-Facing Harness: 26.5-65 lb, up to 49";
Highback Booster: 40-100 lb, 43-57", at least 4 years old;
Backless Booster: 40-100 lb, 43-57", at least 4 years old
STOP using this child restraint and throw it away 7 years after the date of manufacture.
When forward-facing, children should use a car seat with a built-in harness system for as long as possible until they reach the maximum forward-facing weight or height for their car seat. At that point, children should ride in a belt-positioning booster seat. A booster is no longer needed once the vehicle seat belt fits properly, typically when they reach 4 feet 9 inches tall and are between ages 8-12. Be sure to check your local and state laws, as well as AAP and NHTSA recommendations, for car seat usage.*

Great Seat!
Great seat! Switching to this booster from the Graco 4ever allowed us to be able to fit 3 in my husbands rav 4. We have one rear facing Graco 4ever, one slim fit, and this in the middle for my oldest. It is also super light and easy to move around. Only bummer was I wish it had the seatbelt snuglock technology to make sure we got it tight enough.
This seat is great if you need a slim but safe seat.

Great for price!
Great option for our four year old. Only complaint is that the straps sometimes get twisted making it more difficult to buckle when it happens.

Perfect for a tall toddler
This is the perfect car seat for my tall 3.5yr old toddler that wears 5-6yr old clothes. It is a very comfy seat that doesn't take much space and makes her feel like if she was seating on the actual backseat of the car.

Perfectly adequate
It goes in the car very easily and it's relatively cheap for a car seat. However, it is very hard to clean. My daughter vomited in the car and cleaning this thing was a struggle. My other Graco (the 360) is a lot easier and allows me to pull the cloth parts off to wash, without removing straps. On this Graco, you have to remove the straps to get all the covers off.

Best convertible harness/booster
I have now purchased 4 of these for all 4 of my kids. The first one I bought is still in great condition, but we now have 2 in each of our family's cars. Easy to assemble and use daily, lightweight. Flexible. Great purchase, worth the money but is very reasonably priced!

Very nice car for a 4 year old
We are loving our new car seat. My daughter sits comfortably in it and actually falls asleep in it. Her last one she would never. It was easy to install and it’s easy to use. Lightweight and doesn’t take up a ton of space either. Plus we love the color!

Love this seat.
We have the 10 in one car seat which is great. However for our daughters long legs we ordered this which seemed more comfortable for her. It is. We are still keeping the 10 in one to have for backup. We love them both.

Love it configured with the seatbelt guides.
I bought this a month ago and used the full harness which was big enough and easy to use (unlike the previous seat I had). Over the weekend converted from the harness to the seatbelt. The belt is so easy to use. He climbs in and it takes me seconds to thread the shoulder strap thru the Graco. Phew.

Good, lightweight seat and daughter loves the color! It was a bit tough to install tight enough with latches, so just be aware you might need a bit of muscle. Otherwise no complaints - this seat is actually a replacement of the exact same seat after a car accident so we definitely like it enough to repurchase!

Love it! Checks all the boxes!
We bought this seat to transition our 3.5 year old from rear-facing to forward-facing. It was incredibly easy to install! My kiddo loves it and I feel like she is safely snug within the harness. Also the seat sits at just the right recline that when she falls asleep on the car her head doesn’t fall forward. I feel like this is the best seat for safety, comfort, ease of installation and affordability. Would definitely recommend to everyone!

It’s hard to get it to sit straight when it’s buckled in to the car, it wants to lean one way- (we’re still using the 5 point) I’m a car seat tech and I still can’t get it to not sit on an angle once the seat belt is buckled

Safe, sturdy
I was in a bad car wreck with my children a couple days ago, and this carseat kept my youngest in place, and didn't get damaged while we rolled in the car, it was also secured very tightly thanks to my husband.
Safe to say we will be going with this brand again when we get a new carseat.

great seat. very tricky install
Love the size and weight of the seat, taking one star off because its awful to install. I got this seat because I wanted to have a lightweight seat for my son in case of travel. However, I worry about my ability to quickly install it into a different car at a vacation destination. I haven't found anything on the market as affordable or lightweight so I decided to keep it, but the difficulty of install is really a drag. I search high and low for tips and tricks to make it easier but overall I haven't found a quick or easy way ot manage the install.

Cheap garbage latch system buckles
To adjust the buckles for the latch system usually takes about 45 minutes. As they get tight they jam because the seat edge that they must stretch over is too tight a curve and wrinkles the belts. Absolutely horrific buckle usage.

Good next step for an older toddler
Switched from an all in one to this for my older child. It provided more leg room and gave me a better view out the rear window. It provides the same Graco safety I had in my all in ones in a lighter package. The install was the same as my other Graco seats and it should be the last seat I but for my child as it can adapt as he grows.

Perfect
My daughter was not quite ready for the booster when my son was outgrowing the infant bucket car seat, so this was the perfect solution! Same graco quality as always. The buckle is a little different though, which we are still getting used to.
