The SecureTech™ red-to-green indicators on the seat’s base allow you to see when your base is locked in place when using the SafetySlide™ feature.Enjoy quick, easy installation every time without having to tighten the connectors manually—you can easily attach the base to the vehicle seat in just seconds with the rigid LATCH connectors.When using the vehicle belt, installation is simplified with SecureTech™—Safety 1st’s innovative technology that solves the most common installation problem 7 out of 10 parents unknowingly have: loose vehicle belt tension. The red-to-green visual indicators show when the seat belt has tension.The ultra-lightweight design at just under 8 lbs. makes it simple to carry, too. The 4 harness heights are designed to give your child a better fit from 4–30 lbs. and less than 32". The harness adjusts easily from the front of the seat with a simple pull to securely fit your child. The buckle adjusts in two ways so that you can customize the length and the buckle’s position on your child. Since every car is different, you can also adjust the base height for the right fit to your car. Your baby will be nice and comfortable relaxing in the soft fabrics and plush padding. Smaller babies get the extra support they need with head and body inserts that can be removed as they grow. Additionally, the extra-large canopy with zipper extension offers more sun coverage and makes it easy to check in on your little one without adjusting the canopy.

[This review was collected as part of a promotion.] I received this product through the Stellar Product Testing Panel and we love it! At first when we got it we were amazed at the quality of the car seat and the size of it. My baby fits very well, it's a lot more spacious than his previous car seat and we were happy about the way our baby fit perfectly well while it still being spacious. The look and design is super modern, I love the design and the simplicity of it and love how affordable it is. The sliding feature on the base was such an awesome feature for us, we love that we can slide our little one out of the car seat without having to reach in so far to get him out. I will say that even if you don't want to use the sliding feature, this car seat is very easy to take out of the base regardless. It's very accessible both way's, we don't struggle taking him out or putting him in. The installation process was also very easy, my husband had no problems putting the base in at all, we did like how it had the little opening to guide the seatbelts which made the process easier for us to install the base without the seatbelt getting tangled if you prefer that option, it's easy to install it that way. However it has a LATCH system which is also super easy to install the base, so both ways are very easy. Other brands that we've tried were a bit more complicated but this one was very straight forward and very simple, it has very simple instructions and we both loved how easy it was to install the base. I also love how secure it is and I feel like my little one is very safe. My favorite part of this car seat I would say would be the way that the car seat is designed, I love that the car seat is spacious and not so tight around my baby and I love that it's so modern looking, the colors which were dark gray and black, are very simple but it makes it look like a high end car seat at an affordable price. I feel that it was thoughtfully made to make your little one more comfortable and safe so that's a huge plus for me. If your debating to get it I would say go for it! You won't regret it!

Easy to use
[This review was collected as part of a promotion.] No complaints! This car seat was very easy to install and use. There are four adjustable heights for the shoulder straps, which seems to offer enhanced safety, as you can get a more personalized fit for your baby (most other car seats I've seen only have three heights). The car seat itself (without the base) is very lightweight, even with my 11-month baby. He will likely hit the maximum of the height/weight limits soon, but for now, it's still easy to carry him in the car seat into restaurants, running errands, etc. We have the Basalt Stone color, which is very neutral and has been easy to clean - even after our little one was unfortunately sick in the car seat. The size of the canopy is nice; our baby has been able to nap on the go, while we can still see his face to make sure his airways are not obscured. The ability to slide the seat sideways is very nice. We haven't used this feature a ton since we have a larger SUV and baby's seat is near the door, but I can imagine this would be immensely helpful if you had a smaller car or if baby was seated in the middle. It's definitely a feature that I haven't seen offered by other car seat brands. Also love that this car seat can fit into a stroller for ease on the go - we will definitely be looking into some of these options in the future!
Thanks to the Stellar Product Testing Panel for providing me with this infant car seat.

Safety 1st Onboard Slide with SafetySlide
[This review was collected as part of a promotion.] I like that the look of the car seat is neutral, with black and gray coloring. The design of the car seat was functional, but also sleek and easy to carry. I appreciate that it is lightweight- which makes taking my daughter in and out much easier. The base is large- but still fit well in the middle of my car's back-seat.
The slide feature was helpful! I have read that the middle of the back-seat is the safest for an infant, so it was useful in order to slide her closer to the door in order to retrieve her from the vehicle. I'm excited to continue utilizing this as a feature, and glad I received this infant car seat from the Stellar Product Testing Panel.
The manual and directions were straightforward and made installation fairly simple. The base is somewhat bulky, but once it was put in- it fit well in my sedan.
I like the functionality and easy to carry capability of this car seat the most. I also appreciate that it feels secure and safe for my child!
