Great Booster car seat!
Wow, this carseat is great! We had to get a new carset for our 3 year old and she loves this one. We also love that it grows with her and we do not have to keep buying something new when she grows. Easy to install and it sits perfectly in our Equinox Only pain was actually being able to adjust the straps. After a little bit of a fight I figured it out.

Easy to install
Great quality and very sturdy! The Baby Trend Hybrid 3-in-1 Booster Seat was easy to install and feels safe and secure. My child seems very comfortable on long rides, and the seat padding provides great support. I also love that it grows with the child definitely a great value for the price. Highly recommend for parents looking for safety and comfort in one seat!

Tethering Hardships
Tethering straps are a bit of a challenge. They don't fit right and can't be tightened so you need to use the car seat belt whether you want to or not. Other than that great car seat! Easy to assemble, though that seems a strong word for getting everything lined up. I love that the extra padding is reversible. Other reviews mentioned the straps for the harness are a little short. This does seem to be the case.

Comfortable!
Super cute but also has great support for my lil one. Easy to install and also strap. Love the color and the multi stages. I don’t have to worry about buying a car seat for life.

Granddaughter loves it
Brought this for my granddaughter who is 18 months old. She absolutely loves it and that she can sit face forward and be able to see everything. She use to fall asleep in her old car seat and couldn't see anything but the back window. But now since she can see forward she doesn't fall asleep anymore. My daughter in law fell in love with this car seat because of the fact that its a 3 in 1 and my granddaughter can grow into and so I decided to get it. It was very easy to install, they had no problems at all. I may just get one for my vehicle as well.

Straps are too short-Do Not Buy
I want to warn parents about this chair to prevent them from experiencing the same issues I faced. I had a good experience with the previous version of this chair, so I decided to buy this one. However, it was a mistake. The chair is cute, but the straps are too short for practical use. I contacted the manufacturer today, January 6th, 2026, to report the problem. I told them I purchased this chair in October 2025 and asked if they have replacement straps for this model. They responded that they do not. I explained that the chair should last the kids more than just 3 or 4 months, so I asked if they would send a replacement strap. They said no, because there's no replacement strap for this model, and that they would only troubleshoot the issue. I asked what troubleshooting entails, and they explained that it involves documenting the problem on their end. The short strap makes it difficult for me to tighten my three-year-old properly. She cannot even use the car seat if she wears a sweater or a jacket because there are no straps left to pull. Stay away from this chair—you're wasting your money because it won't last, and the manufacturer won't do anything about it.

Grandson loves it
Perfect for my grandson straps a little hard to adjust especially the bottom buckle. Plenty of room to grow in it.
