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.

  • 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.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

Deserves more Stars
Size: Queen
I was very hesitant to make a pillow purchase off Amazon. Turns out it’s the very best purchase! I had chronic neck issues the chiropractor couldn’t resolve. It was the first time, I had an unsolvable issue. I finally decided to spend the money and buy new pillows. My neck issue was 95% resolved the next morning. I’m not kidding! It’s now 100% resolved after a very short period of time. They are a wonderful gift to myself.! quality is top-notch. The support is fantastic. They adjustability is phenomenal and you can adjust the firmness because they give you extra foam. They’re completely worth every penny. I’m 61 years old, 100 pounds and very active. Waking up with neck strain was horrible.

I Hit It With the Dryer and It Became a Real Pillow!
Size: Queen
This DreamyBlue Moon Pillow made a much better first impression than I expected. Out of the package it looked like it needed a pep talk, so I threw it in the dryer to fluff it up and it came back with purpose. Just full on BAM. Pillow achieved. The shape is one of the best parts. It actually feels like a pillow that wants to do its job right. Not too weird, not awkwardly bulky, not one of those ones that looks promising until you lay down and realize your head is now parked on a bag of chopped foam and bad decisions. I also really liked being able to customize it. That part matters more than people think. Pillows are weirdly personal, and most of them give you exactly one option: deal with it. This one lets you adjust the fill until it actually feels right, which is a whole lot better than waking up annoyed and pretending it is fine. And for anyone wondering, mine did not have any weird smell. No chemical funk. No “maybe this needs to live on the porch for a day” situation. It just fluffed up, felt good, and got to work. Overall, this has been a solid win. Comfortable shape, easy to adjust, and none of the usual nonsense. Which, for a pillow, is honestly a strong performance.

Soft yet supportive
Size: Queen
I have been through 4 other pillows in the last year trying to find one that supports but isn't too firm. I gave this one a shot and am really loving it. It's soft, comfortable, supports without hurting my neck or shoulder. I am short so some pillows are too high for me. I'm mainly a siide sleeper, this pillow is great as I can place my head anywhere not just middle of very end like the other pillows I was trying. I can sink into it a little yet still have support and it doesn't crush down. It comes with more filler but haven't needed it. I put it in the dryer on ultra delicate when I first got it and it fluffed nicely. Very happy with this product as I am now getting more sleep.

Absolutely in love with this pillow!
Size: King, Size: King
I’m so excited about this purchase — this pillow turned out to be amazing! I’m a side sleeper most of the time, and the way the edges are designed makes it incredibly comfortable and supportive. What really surprised me is that even when I slept on my back (which I normally don’t like), I felt super comfortable. I actually woke up still lying on my back — and that never happens! I know it’s healthier to sleep that way, so I’m really happy about that and hope it becomes a new habit. Before this, I tried a few regular memory foam pillows, but they always felt too firm and my neck would get tired. This one, with the shredded memory foam, is so soft and cozy — it molds perfectly without feeling lumpy. The King size is perfect too — my little Pomeranian loves to rest his tiny head next to mine on the pillow. I don’t know why he does that, but it’s adorable. And I have to mention the packaging — the box was so high-quality and beautifully made that I just couldn’t throw it away. I’m definitely keeping it to store something in. Overall, I’m super happy with this pillow and will be ordering a second one soon. I only got one to test it out, but now I’m totally convinced. Thank you for such an awesome product!
