Best seat ever . Must read
We've been through many seats this is my favorite to DATE . My 4yo and 3yo use these for reference . They are machine washable and come with a "butt pad" that is easy to remove perfect for any accidents spills or if someone pukes (ask me how I know lol) They are easy to adjust the straps to my kids can use either seat and with one hand and 3 seconds they are safely adjusted to their size. The cup holders are great as they sit lower with my kids like . And with there being no real barriers on the seat the kids have more "leg spreading" room . They also really love the shoulder pads (no more lines on their necks or shoulders) These are also lighter than your typical seat . I can carry easily with one in each hand to transfer cars (I'm 5' for reference) . It s also so easy to get a good install on them . Trust me I was skeptical with he price being under 100 at the time but I can confidently say that if offer this seat or a 500 dino ect for free I would choose this one 10x out of 10 .

Perfect for smaller back seats
I recently purchased the Graco Tranzitions 3 in 1 Harness Booster Seat for my toddler and I couldn't be happier with my purchase. The seat is easy to install and adjust, and it provides excellent safety and comfort for my child. One of the great things about this booster seat is its versatility. It's a 3 in 1 seat, which means it can be used as a harness booster seat for younger children, a high-back booster seat for older children, and a backless booster seat for even older children. This feature will save us money in the long run, as we won't need to purchase additional booster seats as our child grows. The seat is also very comfortable for my child. The padding is plush and supportive, and the seat has multiple recline positions, which is great for long car rides. The cup holders are also a nice touch and very convenient for holding drinks and snacks. I was also pleasantly surprised by how compact this booster seat is. It was able to fit easily in the back seat of my Mustang, which has limited space, and it doesn't take up too much room when not in use. Overall, I am extremely satisfied with my purchase of the Graco Tranzitions 3 in 1 Harness Booster Seat. It's a high-quality and versatile booster seat that provides excellent safety and comfort for my child. I would highly recommend this product to any parents looking for a long-lasting and practical booster seat for their child.

Definitely Happy Customer
I was going back and forth between 3 different ones and decided to skip the cheaper ones for this one, mainly because the others said they were flimsy. This was totally worth the extra $50. Its not bulky, its sleek color, great size and still feels extremely sturdy while being light weight. Love that for that little extra as well my child has a car seat up through their youth as well. Easy assemble and install. Comfortable with extra padding pad. A little iffy on the cup holders but we shall see.

One of my favorite seats!!
This is the second one of these seats I've bought, so o figure it's time to write a review. This seat held up exceptionally well in a 60 mph side crash. On the side the seat was installed, no less! Thanks to Ford and Graco, my husband and daughter came home to me safely that evening. There is truly no higher praise for a car seat. On the everyday side, this is the seat I've been recommending to everyone with forward facing kiddos and those with multiple kiddos. It's perfectly narrow for 3 across situations. It is simple to install (not quite Chicco simple, but definitely second place in my experience!). It adjusts really easily, so I keep this in our second car and adjust it between my 3, 4, and 6 year old daughters with ease depending on which one is coming with me alone. They all say it's comfortable. With three young children, two cars, and a grandparent car to furnish, I've had experience with a lot of different car seats and seat/vehicle combinations. This has been my go-to seat lately because of its beautiful simplicity. It's not fancy, it's not expensive, but it kept my daughter alive and easily does its job day after day and that's all I could really ask for!

Good car seat
Great car seat, have had it for years. My son preferred the back on as the booster itself didn’t fit right in my car but it’s been very reliable. Kind of not so great cup holders though.

Una muy buena compra, no me arrepiento, mi hija tiene 3 años 6 meses y pesa 15 kg y lo siente muy cómodo y le quedo súper bien, es muy fácil de instalar y de ajustar los cintillos. Cuando se queda dormida reposa su cabeza en los cojines de los lados. Además está super bonito. Va cómoda y muy segura ⭐⭐⭐⭐⭐

It's definitely smaller profile than typical car seats, but not exactly slim enough for the middle passenger to feel fully comfortable (it's a huge improvement over the standard Graco one though). We didn't utilize the left bottle holder so that the passenger has a tad more wiggly space. The little nugget loves her chair and had slept soundly on it multiple drives now. Seatbelt is secured as per usual Graco standard, and the water bottle holder fits smaller insulated bottles (up to 14 to 16oz) and disposable mineral bottles, but would not fit those >20 oz insulated bottles.

El asiento es bastante bueno, trae suficiente acolchado y los acabados de las costuras en general son buenos, se siente bien hecho, esté en especial podría ser el único asiento que si hijo(a) use pues se ajusta a todas las etapas, dandole un gran plus. Ahora instalar el asiento es relativamente sencillo si se sabe que se está haciendo, trae sistema LATCH (ISOFIX) que debe de estar disponible en todos los autos vendidos en norte América desde 2003, usandolo queda en 2 minutos o menos, ahora usar el cinturón del auto es un poco más engorroso y depende mucho del auto, al menos 1 de mis autos es todo un dolor de cabeza usarlo, pero eso es culpa del fabricante del automóvil no del autoasiento en si, es importante mencionar que el autoasiento está diseñado para que se use con LATCH Y CINTURON o solo uno a la vez, las instrucciones son claras y que método instalar depende más del peso del niño(a), pues por ejemplo solo se puede usar LATCH hasta 18kg(40lb) después es OBLIGATORIO el uso del cinturón del auto, ademas como el asiento es para muchas etapas se puede ajustar de muchos modos, POR FAVOR LEAN Y ENTIENDAN BIEN LAS INSTRUCCIONES POR SEGURIDAD DE SUS HIJOS. Recomiendo registrarse en la página de GRACO, pues si hay algún RECALL es el único modo de saberlo, la seguridad es primero.
