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.

  • Don’t miss out on this deal!
Color: Denim Blue
I wish I would’ve caught this sale. I purchased the blue seat for my 18 month old. I absolutely love this seat. My baby girl is super comfortable in it! Quality and design are on point. It’s not too bulky but still secure. I prefer it over the Nuna seat.

  • 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

  • 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

Love this seat. Very well built and designed, it feels natural when you’re installing it and buckling the little one. I had the Nuna all-in-one from Nordstrom and spent $400 on it; this one is better.
