    • Perfect Growing Booster Seat!
Color: Proof 2.0
We love the Graco Tranzitions 3-in-1! It started as a secure forward-facing harness for our toddler (up to 65 lbs), then easily converts to highback and backless boosters as they grow, all in one seat. Super simple to install, lightweight for moving between cars, and the no-rethread harness/headrest adjustment is a lifesaver. Dual cup holders, machine-washable pad, slim design, and great comfort. It’s held up perfectly and gives us total peace of mind. Affordable and reliable, highly recommend! ... show more

    • Great carseat
Color: Proof 2.0
Our son is about 40" tall and 30 lbs. Perfect size for him. Much easier to get in the car than our other transition carseat. Plenty of slack on the seat anchors make it a great fit for many cars/trucks/suvs. Easy to put together and super light. Would definitely buy again.

    • Good upgrade!
Color: Proof 2.0
A good sleek upgrade for my son! Takes up less room and makes him feel like he’s in a booster like his brother. We like it. Feels safe too! Easier to take in/out than a car seat. Padding seems good for him, no complaints yet.

We bought this car seat in hopes of it being almost 5 year olds son last car seat. Well I wish we would’ve known about it sooner, he still occasionally falls asleep in the car and to our surprise he can sleep comfortable on it without his head bobbing. He loves that it comes with cup holders and can also buckle himself in. Recommend! ... show more

    • My grandkids love this one
Color: Proof 2.0
This was the perfect car seat for my grandkids. I had one from a different company, it’s fine. This one is so much better. Extremely easy to take in & out of the care easily. Since I am the grandparent I don’t always need to have a car seat, but when I do I don’t have to struggle with putting this one in. My granddaughter, 4yrs old, loves it ... show more
