Daughter loves the car seat and color !
I can honestly say this is one of the best purchases I’ve made for my kid—hands down. The Graco Tranzitions 3-in-1 Harness Booster Car Seat has been exactly what I was looking for: safe, versatile, and incredibly practical for everyday life.First off, I love how it truly grows with your child. It transitions from a 5-point harness to a high-back booster and then a backless booster, so I know I’m set for years without needing to upgrade again. That alone makes it a huge value.What really stood out to me is how lightweight and easy it is to move. Whether I’m switching cars or traveling, it’s not a hassle at all—something I didn’t realize I needed until I had itInstallation was surprisingly simple, and once it’s in, it feels secure. The no-rethread harness and adjustable headrest make adjustments quick and stress-free, which is a big deal when you’re dealing with growing kidsMy child is genuinely comfortable in it—falls asleep on longer rides, no complaints—and I appreciate the little things like cup holders and easy-to-clean fabricBottom line: it’s affordable, practical, and built to last. If you want a reliable car seat that checks all the boxes without overcomplicating things, this is it.

Flawless from start to finish, and looks EXACTLY like the photo on the box it comes in 😉 lol
It’s a GREAT product and company. Very happy with the install and the overall look and fell. It has space for life, including cup holders and padding that seems sufficient. And I love how light it is.. it’s a good value for the money. No issues with the straps or anything to date, just a solid product that looks good! I am very happy with this product. Straps are TIGHT and this is easy to use. What more can you ask for out of a booster seat/car seat!? Happy all around. 10/10 I enjoy. 🙂

Perfect Growing Booster Seat!
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!

Absolutely love it!!!!
FANTASTIC!!!! I originally ordered thr Chico car/booster seat. Then found this & returned the Chico immediately! This is a great product. Love Graco, the seat and back are very nicely padded for comfort, the head rest goes very high with a great amount of support! The straps are very easy to use, comes with adequate shoulder pads for comfort, the straps also have a very easy press release. The cup holders are reversed into the slot so you just have to remove them & turn them around. Kids love the comfort, it’s also light to carry & easy snaps together, I bought 2!

Fits, secure, comfortable!!
EXCELLENT carseat!! Fit perfect in my car and can still SEE out my back window!!! My daughter LOVES it, and it doesn’t tip all over!!Last one we had, even with ALL 3 anchors fastened TIGHT, STILL would lean!She is comfortable, loves the cup holders, and sits perfect in my car. Happy to know it will grow with her and we never have to get another crummy carseat again! THANK YOU!!

Transitional car seat
Love the car and the size for my toddler. It fits nicely in the back seat of my truck. I bought the tan color because it was on sale but it does show stains really easily. I would definitely get the black if I had to buy another.

Much needed for my kids
The Graco booster seat has been a solid, practical choice for our family. It’s easy to install, lightweight enough to move between vehicles when needed, and fits well in most cars without taking up too much space.My child finds it comfortable for both short trips and longer drives, which is a big plus. The padding is decent, and the seat belt positioning feels secure and helps keep them properly aligned while riding. I also appreciate that it grows with your child and can be used for a good range of ages and sizes.Cleanup is simple too—spills and crumbs wipe off easily, and the cover is manageable when it needs a wash. It’s not overly fancy, but it does exactly what it’s supposed to do: keep kids safe and supported on the road.Overall, it’s a reliable booster seat that feels safe, practical, and worth the price for everyday use.

Fácil de instalar y materiales de buena calidad.Es una buena compra sin dudarlo
Llego en tiempo adecuado para niños de más de 2 años. –
Llego en excelente condiciones. Util para no cambkar de sillas conforme crece tu pequeño o pequeña. Tomar en cuenta que tiene menos soporte lateral a nivel de los brazos y piernas, pero nada grave.
