  • Great toddler car seat
This Cosco car seat is sturdy for my toddler. I purchased it as it’s ideal for travel. This one only weighs 11 lbs but it’s still well made and I was impressed by its safety reviews and the price. We typically use the Chicco OneFit car seat, but it’s much heavier at 25 lbs and definitely not fun to lug around when traveling. This Cosco obviously doesn’t have as much plush padding as the Chicco OneFit, but it’s still good quality and my daughter had no problem sitting in it for hours, never complaining about her bottom hurting. It has a simple thin neoprene seat cover that can be removed and washed as needed and comes with a cup holder. It was easy to re-thread the chest straps to adjust based on her height (came at the lowest setting but she needed it at the middle setting). We do front facing since she’s 40 lbs and it’s sturdy with the Latch system. This is ideal for travel use and occasional use with her grandparents, who have a smaller car. The sides do have a little area for her to prop her head when she falls asleep. Would definitely buy again! ... show more

  • Safe and sound
We bought this to use out of town with family. Easy to install and my kiddo says it's comfortable. We use it now whenever we travel because it's lightweight to switch around in family members cars. I like knowing my kid is safe!

  • Great fit for older toddlers
Perfect for my daughter. She’s a big 3 year old so this works. It’s also light weight. We haven’t installed yet. I’m sure it’s going to be fine.

  • First trip in 3 years!
Color: Dusk
We bought this for our 4 year old (45lbs) to travel internationally for the first time in 3 years and we didn't want to lug around his Graco....or risk it being damaged. We needed a seat in our rental anyway and we figured he would be more comfortable on the plane as this was his first time. Things I liked: super lightweight. At first I thought it would be flimsy but it was good! I have some issues walking around and was worried it would be heavy to lug around, but it was fine considering going through customs was a chore. It is rather bulky. The planes we were on were TINY but it fit in the seat just fine. Kiddo was happy in it! And it worked perfectly in the car/ cars. It was super easy to install....but...... Things I didn't like: ....... getting the belts to get through the back of the seat on the plane? Tough and I have tiny hands. My entire arm got bruised but that's not the seats fault! Once it was in, it was FINE. It was a pain to lug it around and next time we would gate check it. Also, the straps got super tangled because it was being moved around and by the time we got to our last flight, I was over it. Overall: GREAT for traveling and on the plane. Fits even the tiny seats and my kiddo was super happy in it. Loved how it was portable and YES! IT IS FAA APPROVED. We only had 2 times we were asked so he prepared to show it (the seat is labeled clearly on the back). Is this our go too? Nope. Is it a great second seat for other people who are watching him? Absolutely!! ... show more

  • Great seat for growing toddlers!
I got this seat for my growing toddler son who is 3 years old. Just because this is a cheaper car seat doesn’t mean it’s not a safe car seat. I choose this car seat after looking through my options for a few days/ weeks. I ended up going with this one through the reviews I read. All car seats are safe! They protect our babies. Not having one and reading the instructions and following them is what makes them unsafe! ... show more

  • Fits very well.
Bought this for my granddaughter soon turning 3. The seat is now facing front for her. She fits very well into it. She weighs almost 30 lbs and she will grow into it until she is about 5 or the equivalent weight. The item is sturdy. It came as described and it was easy to install in the car. Color is also very nice, a light pink. ... show more
