The Cybex Sirona S stands out as the only convertible car seat that features a 360° rotatable seat, providing exceptional ease of use without compromising safety. With its innovative load leg stability and advanced linear side impact protection, this car seat is designed to keep your little one safe during every journey. Moreover, the integrated SensorSafe™ technology enhances parental peace of mind by ensuring you receive instant updates about your child’s well-being directly to your mobile device.

Cybex Sirona S 360 Rotational Convertible Car Seat Features

The Cybex Sirona S is equipped with an EasyLock™ bar that simplifies the installation process, making it the only convertible car seat in North America to feature a one-time vehicle belt installation for both rear-facing and forward-facing modes. The load leg enhances stability by transferring crash energy to the vehicle’s floor, effectively reducing the risk of injury during an accident.

  • 360° Rotatable Seat: Easily rotate the seat to get your child in and out without straining your back.
  • Load Leg Stability: Significantly reduces crash forces and stabilizes the seat during an impact.
  • EasyLock™ Bar: Quick and secure installation with up to 4x less force needed.
  • SensorSafe™ Technology: Alerts you about your child’s safety via a mobile app.
  • 12-Position Recline: Adjust the seat to any of 12 positions, even with your child buckled in.
  • Linear Side Impact Protection (L.S.P.): Absorbs impact forces to enhance safety during side collisions.
  • Anti-Rebound Design: Minimizes rearward movement in the event of a crash.
  • Magnetic Buckle Holders: Simplifies getting your child in and out of the seat.

What Is SensorSafe?

SensorSafe technology is a groundbreaking feature that brings safety to the forefront. This smart chest clip sends alerts to your smartphone, notifying you if your child unbuckles themselves or if the temperature inside the car becomes too hot or too cold. This level of awareness is designed to help you focus on the road while ensuring your child is safe and secure.

Designed for children from 4 to 65 lbs and a height range of 17” to 49”, the Sirona S ensures that your child can remain in a rear-facing position for as long as possible, enhancing their safety. It’s essential to keep them rear-facing until they reach the maximum weight or height allowed by the car seat. For the Sirona S, the rear-facing limit is 50 lbs, while forward-facing can accommodate up to 65 lbs.

This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel

I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
