About this item
- All-In-One Car Seat: The CYBEX Eternis S is the only seat your child will need from birth and beyond. Featuring rear-facing, front-facing, and belt-positioning booster modes, the Eternis S is designed for use from birth up to 120 lbs.
- Linear Side Impact Protection: The Linear Side Impact Protection system (L.S.P.) absorbs up to 25% more impact forces in certain crashes when compared to the same car seat without L.S.P. extended.
- Patented Reclining Headrest: The Eternis S headrest helps prevent the child's head from falling forward while asleep, keeping the head and neck in a safe position. The headrest also features 12 height settings for easy adjustment as your child grows.
- 10-Year Car Seat: The seamless transitions between modes offers up to 10 years of use from your Eternis S. An in-seat recline helps provide correct ergonomic positioning and extra legroom that lets your child ride rear-facing for longer.

The installation was pretty easy - although the instruction manual could be set up better in regards to using the cars LAP/SHOULDER BELT vs the lower anchor and their breakdown for weight limitations. You can use the lower anchor system to install until your child is 40 pounds and then you need to use the lap belt.
Rear-facing from 4 lbs. to 50 lbs.
Forward Facing from 22 lbs. to 65 lbs. (up to 40 pounds you can use the Lower Anchor system otherwise you need to use the cars LAP/SHOULDER BELT) Either Method you need to use the Tether.
Belt-positioning Booster from 40 lbs. to 120 lbs.
A tip when installing with a seat that reclines slightly - my Subaru outback features slightly reclining seats - this really helps to tighten the LAP/SHOULDER BELT. Lay the seat back as far as it will go and get the lap/shoulder belt though the back of the carseat as instructions show and ensure the Lock-Off is engaged - from there just tighten it as much as you can by pulling the lap/shoulder belt to remove slack and then bring the seat up to the correct position - this should help you get a tight installation!

L.S.P. - The Linear Side Impact Protection extends from the side of the seat that’s closest to the vehicle door.
I found adjusting the Headrest was super easy once I figured out how to move the toggle on the back of the seat, along with that the headrest is adjustable! This is a wonderful feature to help ensure your child is comfortable.
Headrest Adjustment - You will find this lever mounded below the headrest behind where your child's neck would be if they were sitting in the seat. Ensure it locks into place after adjusting.
Reclining Headrest - The headrest on this carseat is adjusted independently of the height adjustment and this handle is right at the top - while my first instinct was that this would adjust the height I was wrong. Depending on your
Guidelines for the headrest recline positions:
Height adjustable positions 1-3: no recline available
Height adjustable positions 4: recline 1 and 2 available
Height adjustable positions 5-12: recline 1,2, and 3 available
The top Tether is one of the most important safety features of a forward facing car seat - but if you are using this from birth, you won't need that right away and it is tucked into the back in a pocket that you just pop open from the top. This is also where the manual is stored - when you have your carseat installed forward facing that does make getting to it a bit difficult - but the digital manual is easy to find on the Cybex website.
Booster Seat - Easy enough to convert - but please read the manual as there are a few steps that you do not want to miss, such as how to fold the crotch buckle forward into the compartment on the seat pan as it stays attached to the carseat base. From there the Top Shoulder Belt Guide is easy to use and at a nice height. This booster is large enough at the base that it might be difficult for your child to buckle themselves in without engaging the locking mode.
FAA Approval — the Eternis S is approved for use on aircraft when it’s in harnessed mode. The FAA Approval label is located on the bottom of the seat. Since the Eternis S weighs in at 25 pounds, we’d be pretty surprised if too many families end up using it for travel.
Date of manufacture label — the Eternis S expires 10 years after the date of manufacture. Both the manufacture date and the expiration date are on a label on the bottom of the seat.
Overall Thoughts - The Eternis S features a plush cover and an excellent fit for both of my children in both harness and booster mode. Both of my children found it to be comfortable.
