Car seat
I am really happy with this carseat! The install was pretty straight forward thanks to the rigid latch system! It feels very secure once it clicks in which gives me peace of mind! The seat itself is pretty light weight so it’s not a struggle to carry it in and out of the car even with baby in it! The canopy is larger than most I’ve seen which is great at keeping the sun out of my little ones eyes. The fabric feels nice and comfortable and I like the muted dusty green color it looks stylist without being too bright. I love the way it slides out too, makes loading so much easier. Overall I feel it provides great safety comfort and convenience. I definitely reccomend it.

Has been very good
So far so good. I really like the easy install, and the slide is nice since I’m so short. The color is great, and the removable infant insert has been very helpful for keeping the rest clean

This car seat was made for me!
Wow! Now this a car seat. Saftey 1st really did their thing when they came up with this design. As soon as I unboxed it, I knew we were off to a good start. Its heavy duty and solid, and so well made in every made in every way. The dusty green color is beautiful, and the seat is super cushiony and well padded, so baby is always comfortable even on long rides. It has a sturdy adjustable handle, a large canopy to keep him shaded perfectly, and all the safety features you would want to feel your baby is safe and secure. The material is soft and it has a body insert thats plush on every side. My favorite thing about this car seat is of course the base. The slide feature is such a awesome idea, im surprised it wasnt thought of sooner. The base fits well in my car and the seat clicks in with ease. When I need to get my baby boy out of the car, I just slide the seat towards me, lift it up, and he’s out. You wouldn’t believe how much this helps, makes things way easier. No more back pain, head bumps on the car, and since I’m short, know more crawling in the back to get him out. The seat slides smoothly too, so far it hasn’t gotten stuck at all, just easy peasy. Its light weight and easy for me to carry, Im beyond happy with it. Its like it was made for me, my favorite car seat I’ve owned. Would highly recommend. Great quality, affordable, and makes life easier, whats not to love.

Great Quality
This is a large baby car seat and carrier. This has a unique base that securely belts in. The base allows you to easily take the seat out as a carrier when needed. Even better, the carrier will slide out of the car on the base so you don’t need to awkwardly lean in to grab it. That is a huge back saver. This is also compatible with strollers by this brand; take the carrier out of the car, place in a stroller, and you’re off. This has a great build quality, is comfortable for your little ones, it has good padding, and this seems like a good value. This is a good brand, and this didn’t disappoint.

Very easy to install and keeps my niece secure!
I’ve been really happy with this car seat. Installation was super easy, and it feels very secure once in place. The seat itself is not super heavy, which makes carrying it around so much easier. My niece seems comfortable, and the extra-large canopy is a great feature for sunny days especially since it gets so hot where I live. It also clicks easily into the stroller, which is a huge plus. Definitely a great choice! And, for the features, this carseat is a really great value!

This is a nice solid car seat for up to 30 pounds
If you’re looking for a car seat that combines safety, convenience, and comfort especially for frequent in and out trips this one’s worth considering. Compatible with safety 1st strollers quick click attachment. Soft fabrics, plush padding, and removable inserts for infants make it worth the price. The base is heavy but so solid and sturdy feeling, and the red/green latching system lets me know for sure its locked in correctly. it fits in my car and my husband’s truck just right.
