Features

  • 10-Year Car Seat: The seamless transitions between modes offer 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.
  • SensorSafe: The chest clip SensorSafe technology automatically syncs to the phone app to provide alerts if unsafe situations arise, including your child becoming unbuckled, the back seat being too warm or cold, or if the child is seated too long.
  • 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.
  • Converts to Booster Seat: Ensure your child has an age-appropriate seat as they grow. Your Eternis S can be converted into a belt-positioning booster seat with a comfortable high back, suitable for children between 40 and 120 pounds.

Description

Keep your child riding in safety and comfort with the CYBEX Eternis S all-in- one convertible car seat. A must-have on your baby essentials list, this infant car seat is designed to grow with your child. This seat provides up to 10 years of use, first as a rear-facing baby car seat, then as a forward- facing seat, and finally as a belt-positioning booster for children up to 120 lbs. Built into the chest clip, SensorSafe automatically syncs to the app on your phone to provide alerts if unsafe situations arise, including your child becoming unbuckled, the back seat becoming too warm or cold, if the child is accidentally left inside the vehicle, or if the child has been seated in the infant car seat too long. For additional safety, the Eternis S features Linear Side Impact Protection (L.S.P.), which reduces side impact collision forces by up to 25% compared to the same seat without L.S.P. Keep your little one in comfort with a 3-point reclining headrest that guides your child’s head into an ergonomically correct position for sleep. An in-seat recline provides extra legroom when you need it, so your child can safely ride rear-facing for longer.

  • I love this car seat!
Color: Pepper Black
This car seat is so comfy for our LO. Love the SensorSafe feature. Very easy to install!

  • Huge yes for us!
Color: Pepper Black
My really long 10-month-old used to hate being in a car seat. I loved the reviews and safety ratings on this seat so I decided to cough up and pay the hefty price tag. It has been a few months, and I can not rave enough about this buy. The car seat is easy to clean and get him in and out of. One of my favorite features has to be the side magnets to hold the seat belt out of the way while putting him in! My son no longer hates car rides and often falls asleep comfortably. ... show more

  • Amazing quality, extremely secure!
Color: Manhattan Grey
I've been using car seats since my oldest was born, 16 years ago! Safety, comfort, and features have changed SO much in that time. I am usually a loyal Graco and Britax car seat purchaser, but this seat won me over with the extra features. The fabric is smooth, soft, and nicely padded. The 3 way adjustable headrest is going to come in so handy when my LO gets older. Installation was fast, we're talking less than 2 minutes rear-facing. Having multiple recline options means not having to use pool noodles to get a proper level. My LO is 10 months and was all smiles for her first 30min car ride in this seat. I would highly recommend it if you are looking for top of the line safety and comfort! ... show more

  • Good 👍
Color: Manhattan Grey
Good carseat, but the safety sensor button glitches, and the cup holder attachment is a little too far from babys reach. But overall good carseat.

Seat is bigger than others. We tried many other seats but this one big and comfy for big size 1 year old. Rear facing easy to install and remove.

  • Like it, don't love it
Color: Denim Blue
Update: June 16, 2023 I’ve had this car seat for just over a year. The plastic chest piece doesn’t stay locked WITHOUT my toddler touching it. I question the safety of this seat because the chest piece often comes unlocked on its own. Original review: I really like the safety features. It's a good car seat. BUT...soooo hard to take the fabric off. My daughter threw up while we were driving and it was so hard to get the car seat clean. ... show more
