Really enjoyed my Cybex Sirona S2 rotating seat, all the way up to my kid growing out of it. Narrow parking? Rolled down the window and did the seatbelt with the door almost closed. Kid sleeping? Tilt the seat back a bit, so the head doesn’t hang on chest. Sold mine used for 20% of the price of new.
We have the Cybex Sirona S2 for a car seat. Our car is on the smaller side and it has the relatively smallest factor for 360 car seats we could find. The “golden standard” here in the UK is the Joie spin 360 but it’s extremely bulky. Our stroller was an iCandy that we got second hand from a friend. It had the worst closing mechanism i have ever seen in my life. It took me 30 mins to figure out how to close it the first time and i have not met a single person that were able to close it even after i explained it to them. Our parents, our friends, they would all ask us to close it after they used it because they could not make it work (the mechanism was working properly it was just a weird design) And that is what made me realise what i wrote above. After just a week of use, both me and my wife could handle that crime against UX in our sleep.
I have used a Maxi-Cosi 360 of some sort, Cybex cloud z I-size and a sirona (interchangeable on same swivel base) and a seatbelt chomping one too, all on the back seats. For the isofix ones I bought an adapter from Bezos. I don’t put them in the front because they are savages and my front seats are custom upholstered recaros but I much preferred the stability of the isofix adapter.
I’m surprised I had to scroll so far to see this. We got rid of our Evenflo 360 after the reports of it flying off its base started trickling out. We have the Nuna Revv and love it. We also had the Cybex Serona S back when it was the only rotating seat on the market in the US. We weren’t happy with the quality and the seat fell apart after about a year and a half. I’m short, so having the rotating feature is a game changer for me! Now that my oldest is bigger we have the Nuna LUMN, which I also love because it’s very easy to reach the buckles since the sides are low.
We've had both. Cybex 360 generally was just annoying enough to not bother using it.
I'm a big fan of the 360 spin seats, much easier to load/unload from the car. My wife got the fancy Cybex one, but it is a very nice seat and will grow i to a booster seat. I got the less expensive Graco model since they don't ride in my car as often. Good luck!
CYBEX 360. Very pricey but worth IMO
Both parents with back issues (mind your backs - you only get one! 😅) so its a vote for rotation here. Rotating was a huge plus. Tbh the whole travel system was a gift, so that broadened our options. We got the Cybex. The rotating base is used for the next stage seat (which I probably need to order too 😂).
Meillä ollut britaxin istuin, kaksi lasta viihtynyt siinä hyvin. On kyllä aika iso ja raskas vehje. Oli hetken aikaa myös motonetistä hommattu joku Cybexin malli, mutta siinä ei lapset tuntuneet viihtyvän. Se lähti sitten kiertoon ja pienemmälle tuli tuo vanha britax kun isompi muksu tarvitsi isomman istuimen. Tosiaan, käykää liikkeissä koeistuttamassa lasta noihin, ja lukekaa noita autoliiton testejä niin hyvä tulee. Monissa paikoissa myyjät ei kuitenkaan mitään tiedä niin kannattaa pari minuuttia perehtyä tuohon asiaan.
