Finds the Cybex Sirona S not bad to clean, especially while their son is still rear-facing.

“We have the cybex Sirona s and it’s not bad to clean. My son is still rear facing though so easier to take off and on the padding”
positiveeasy to clean

Found the old Cybex Sirona S horrible: the spin was hard to do, it once stuck sideways, and Cybex only offered 10 percent off a replacement.

“We had the old Cybex Sirona S which was since discontinued. It was a horrible seat :( the spin was so difficult to do and required 2 strong arms. The”

Returned the Sirona S because installation was finicky, it wobbled, and the load leg wobbled so much that they worried about a crash.

“I bought the sirona s and ended up returning it. The installation is super finicky whatever you do it wobbles and to rotate you need to move it up and”

Loves the Sirona S swivel for getting a large baby in the car, and their husband installed it without difficulty.

“Been using the cybex one for a month or so now. I have trouble putting my giant baby in the car so the swivel function is awesome. I haven’t installed”

Finds the Sirona S very secure in their car.

“I got the cybex sirona s. It is very secure in my car.”

Their Cybex Sirona S is hefty with a big footprint, but the rotation is so easy that it will be hard to switch to a smaller seat.

“We have a Cybex Sirona S, which is pretty hefty, so that is definitely part of our problem. The rotation is just soo easy it will be hard to switch to a smaller seat.”

The Sirona S works great in their two-door coupe; there is room to spin it, though the side impact piece can rub the B pillar.

“We ended up getting a Cybex Sirona S. It works great in the S5. Not as easy as a four door”

Loves their Cybex Sirona S and finds the seat fabric amazing and comfortable.

“I have the Cybex and I love it. I bought it when it was the only 360 on the market, but I thought it was worth the money. The seat”

Their toddler learned to undo the chest clip, and he is close to maxing out the Sirona S, which they say kids outgrow quickly.

“My 2yo has learned how to unclip his chest clip and now simply REFUSES to have it clipped. We have tried all of the CPST approved “hacks” (the button up”

Loves the Sirona S: when someone parks too close they can use the other door and rotate the seat to face them.

“We have the cybex sirona s and i love it!! As well as all of the things people have mentioned above, I’ll offer a perspective that i haven’t seen yet-”

Loves the Sirona's rotation but found it a nightmare to install in their car and it stops rotating once forward-facing.

“I have the CYBEX sirona. And although I love the rotating part it was a nightmare to install in my Nx200. Also a thing to note is that once you’re LO is forward facing you can’t rotate it”
