EveryFit 4-in-1 Car Seat FAQs

How do I change the position of the crotch buckle on the EveryFit 4-in-1 car seat?

In order to adjust the crotch buckle of the Evenflo EveryFit 4-in-1 car seat you will need to start by removing the booster base from the bottom of the car seat. Once the booster base is removed, you will be able to access underneath the seat where the buckle anchor is located. Turn the anchor to remove from one slot and place into the other slot. Please refer to the product instructions for details on when to change the buckle position.

I removed part of the EveryFit car seat cover while installing my car seat rear-facing, but now that the seat is installed I can't get it back on.

It does help to remove a portion of the seat pad when installing your car seat so you can better access the seat belt or lower anchor strap. When installing your EveryFit in rear-facing mode, instead of detaching the portion of the seat pad near your child's feet, detach the seat pad from the back of the seating area. The back portion of the seat pad lifts up to expose the white handle for removing the booster base. The back corners are held down by small elastic loops. Remove the elastic loops and you can lift the entire seat pad towards the front of the car seat. Removing the seat pad from around the crotch buckle allows access to the entire rear-facing belt path.

When your installation is complete, route the crotch buckle through the appropriate slot in the seat pad and reattach the back corners of the seat pad with the small elastic loops.

How do I know if my car seat is tightly installed?

When checking for a tight installation, it is important to test the car seat right where you have it installed to the vehicle. For a rear-facing car seat, that means you will grab the car seat near your child's feet and not near their head. While holding the car seat near the installation area, try to move the car seat side to side and front to back. The car seat should not move more than one inch in any direction.

If the car seat moves more than one inch when checking at the belt path, you have a few options:

  1. Try to tighten the installation again.
  2. Try a different seating position in the vehicle.
  3. Try a different installation method, if possible.
  4. Contact ParentLink for assistance: https://www.evenflo.com/contactus

Does the Evenflo EveryFit have a steel frame?

The Evenflo EveryFit meets or exceeds all applicable Federal motor vehicle safety standards and Evenflo's internal testing standards. These products do not have a steel frame, but are made of robust plastic sufficient to withstand numerous dynamic tests. The Evenflo EveryFit are engineered to manage crash energy appropriately without the addition of a steel frame. This allows the car seat to be lightweight, making it easier to move between vehicles.

EVERYFIT 4IN1 CAR SEAT ATLAS is rated 4.3 out of 5 by 94.
Rated 2 out of 5 by from A pain of a carseat I bought this car seat maybe 3 months ago? I have a big baby so we moved her into it before the average age. It’s a comfy car seat with good padding, BUT it’s a pain to deal with. The strap to tighten the carseat is so hard to pull, I thought we had a bad car seat. Other reviews have the same issue. My next (and most frustrating) issue is installing it into other cars. The strap is so hard to tighten that I CANNOT tighten it. My boyfriend has a hard time too. I do everything I can. Pushing at the base and pulling, nothing. Usually I have to unlatch the side with the strap, tighten it, then try as hard as I can to anchor it into the car. I also try to sit on it to be able to pull the strap tight, but the issue is the strap and it’s inability to tighten. As soon as I have to opportunity, I’ll be replacing this car seat and getting rid of it. The point of the car seat is supposed to be safety, but it it’s moving 5 inches every direction because the straps don’t tighten, that’s not safe.

Rated 5 out of 5 by from Safe at 1000% So blessed to have gotten our everyfit 4 in 1. We were in a car accident last month, our car rolled over and our baby was safe and sound, not 1 scratch. Please buy and use your evrryfit correctly its the best item you can purchase for your babys safety.

Rated 3 out of 5 by from Ups and downs Only have had for a month, seemingly good deal, bought two, one for each vehicle, one in store and one online, shipping was fast. Seems comfortable and my daughter likes it with the cupholders and the head rest is easily movable which is nice. Getting it tight enough not to move side to side was a pain, I am 6' 200lbs and had to kneel in the carseat putting enough down pressure to pull the strap tight enough after hooking it to the cars loops. Not an easily moving from car to car seat, and I cannot drive my car anymore with this seat behind the driver seat, nor can I ride passenger in my truck because those seats need to be all the way up on order to fit this carseat in. Cant wait to switch it to forward facing...!

Rated 2 out of 5 by from Comfort is there, but it’s hard to get to latch I bought this seat a few months ago, and I was amazed at how well it was put together. Fast forward to putting my baby in it... I couldn’t get it to latch easily at all. It took 6 tries to make it stay latched. I thought maybe it just needed to be broken in, which I should’ve known better seeing it is my fifth child and have had seats that are much easier to use. A few months later, and it’s even harder to latch than before. I spent almost $200 on a car seat that I will have to replace due to safety troubles.

Rated 4 out of 5 by from Love this seat! The only complaint I have is the middle strap that tightens the shoulder strap is hard to pull when car seat is rear facing even the fireman that installed it noticed it. But other than that I love this seat and so does my grandson!

Rated 5 out of 5 by from Fantastic carseat! Easy to install, and my son loves it compared to the infant carrier. I just wish the strap to tighten the harness was a little longer and wasn't soo tough to pull- other than that love the style and colors and fit in my ford explorer great. The front passenger still has leg room!
