3.0 out of 5 stars Seat was manufactured in 2017
By Jenn Beswick on June 18, 2019
I want to start by saying I absolutely love this set.

What I was unhappy about is the fact that I ordered this seat in May of 2019 and the seat I received had been manufactured in 2017.

Since seats have expiation dates that are based off the manufactured date and not the date you bought the seat it was very upsetting to have received a seat that was already two years old meaning that was two years less that I could use it.

4.0 out of 5 stars Great seat but not as good as I hoped.
By Amazon Customer on March 8, 2019
Yes, this seat earns 4 stars. It has a lot to offer if you need a 3-in-1. We ordered two different seats to compare and instead went with a 2 in 1 booster:

Love: Click-lock feature that connects the bottom booster to the high back is fantastic. It's easy to use and feels secure. The steel structure tbroughout feels sturdy and safe. The shoulder belt lock system is great for our multiple vehicles (especially our old truck.)
Dislike: Padding could be a lot better. There is a gap below adjustable headrest where the child shoulders should sit- it doesn't allow for the child to sit straight. Like a tall man's recliner, your head is pushed forward. The entire booster can recline to compensate, but will a taller child be comfortable like that or will their legs fall asleep???
CON: the Latch system has the outdated hooks. The metal type you have to squeeze against the bracket in the car's bench/chair. For the price and the implied User Friendly aspect, I think this is a big let down.
Two other things I could have done without:
The trash collector space under arm rest is going to just get gross- lint & dust, snacks, drinks, dirt, doggo hair etc. The cup holders/arm rest are very easy to remove to clean etc. So I suppose you could just do without them which eliminates the cubby. But armrests are preferable for our kiddos. Also, there is no washable cover over arm rests. They are a gummy texture. The type that soaks up sunscreen, food/drink reside etc.

Pros: the carseat as a lot of great features. It will be the carseat to last you, especially if you want a one time investment. Also it is much lighter than the other carseat we bought. Moving it from one car to the next while herding cats shouldn't be a total pain.

The Snuglock checked a lot of boxes for us but ultimately we went with a seat that is a 5 point harness and highback booster (no lap belt only booster.) The seats were the same price. What we didn't get in a lap booster, we got in better, cushy padding. We will buy a single booster later as there really isn't anything special about a lap booster.
