  • Easy, comfy, quality
Color: Dunes Edge Style: Car Seat
My son was 15 months and about 24lb when he started using this car seat. We have it rear facing in a 2007 Toyota Matrix. In this vehicle it has to stay pretty upright, so it would not work for a newborn unless you have no passenger in the front seat. However, it is narrow and we have our new baby's infant seat right next to it in the middle seat, leaving the second door seat for me to sit and feed him when I need to. As for other things, It has a number of really nice features for the price point - I got it for a total steal on presidents day. Comfort: this kid naps and plays and is always happy to get in his car seat. Chest clip: I like! It can be fastened/unfastened with just one adult hand. Height adjustment: SO EASY. no rethreading straps! Straps: easy to tighten and loosen. They do get twisted kinda easy but it really is not a hassle to fix in my opinion. Installation: omg so easy. While it is pretty big to take out, doing so is quick and simple when we need to. I can have it back in place within 1 minute using the seatbelt path. Cleaning: I have yet to truly clean this thing but it seems like it should be easy enough. I'm so happy with this purchase and intend to get another one when my younger baby is sitting independently. ... show more

  • Safe, Comfortable, and Easy to Install
Color: Dunes Edge Style: Car Seat
I couldn’t be happier with this car seat. The padding is extremely comfortable for my child, and the design offers excellent head and body support. It feels very sturdy and secure, giving me peace of mind every time we’re on the road. Installation was straightforward, and the adjustable features make it easy to fit perfectly as my child grows. I also love the built-in cup holders—super convenient for drinks and snacks during trips. Overall, this is a high-quality, well-designed car seat that combines safety, comfort, and practicality. Highly recommend it to any parent! ... show more

  • GREAT!! Would recommend
Color: Dunes Edge Style: Car Seat
I absolutely love the Safety 1st EverSlim DLX Convertible Car Seat! The slim design is perfect for fitting multiple seats in the back, yet it still feels very sturdy and safe. Installation was straightforward, and I really like the SecureTech chest clip that shows when it’s properly fastened—it gives me extra peace of mind. My child seems super comfortable with the soft padding and adjustable recline, and the removable cup holders are a great bonus. I also appreciate that the covers are easy to remove and wash (huge win for parents!). This seat truly grows with your child from baby to big kid, which makes it such a smart investment. I highly recommend it to anyone looking for a safe, space-saving, and comfortable car seat! ... show more
