My tall girl loves it and it supports her head really well when she falls asleep in the car. I’m sure the regular Luna would do the same but that can’t be purchased from The Memo. Never used the chin support.

This is a really great seat! Harness is super easy to adjust which helps get a great fit. Not having to manually rethread the seat harness makes it great if you will be using it for mulitiple children or if you dont want the hassle of dealing with manually reathreading it. The fabric is super lovely and cool, which helps keep my child cool in the car. The only downfall to this seat is its rather large so it does take up a lot of seat room in the back. However, this won't matter if you have a bigger car or only using 1-2 seats in the back of your car.

Great seat depth and full adjustable harness. Mr 5 found it the most comfortable of several he tried. Easy to install. Don’t like the “easy” adjust headrest/harness as hard to get it to release to adjust. But given that only infrequently worth it.

Easy to fit into the car and a great size with ample room for my three year old. Also great head cushioning to give him comfort for if he naps in the car
We had to upgrade our toddler to a bigger seat, and found this seat to be roomy and very comfortable for him.We appreciate the stiff yet spoungy shoulder pads, which help protect his neck against the seatbelts.And the fact the arm rests go up and down, so he can climb in and out easily.He loves his new big boy car seat!Great work Maxi Cosi!
Overall the seat is great for comfort, it is easy to use and when it's reclined my son's head doesn't fall forward. What's strange about it is that the 'world's first chin support' doesn't work. All he needs to do is lean his head against it and it goes back in. There's no point having it there as it doesn't do anything. Surely when it was tested before being released on the market this would have been identified. It's disappointing as it's an expensive seat. I'm also worried about it's crash safety after reading one of these reviews. So not sure if I've bought the right car seat.
My daughter loves her Maxi-Cosi chair. The chin support, especially, makes is easier for her to nap in the car while we are driving. Easy to install and adjust, and the straps don't twist. I would definitely recommend buying this chair.
It was the cheapest price I could get compared to other sites. Delivery was super fast. The chair is on the bulky side. We have a Polo GTi and it takes up a bit more space than our Maxi Cosi Moda. But we love the comfort it gives and the side buffers to reduce impact in an accident. I don't like the harness because I have to keep buckling my kid in and the belt keeps twisting. My kid can go up on her own but still needs me to buckle her in till she's 8! But it is safer than the ones that use the car's safety belt. My kid also loves the cup holder on both sides and arm rests.
I had an amazing experience in this particular shop! They were super friendly gave me the right guidance and even helped me to install everything in the car safely. Top Performance. Especially by Yvette.
Easy to install and fit securely. Looks very comfortable for my little one and looks great in the back seat
