I am someone who got alerted that my friends child was left in car, and where car was. Because of covid child was being cared for by relative who normally did not care for the child. Child is fine care of alert. Thank you to whoever came up with this **Q: I installed this with the seatbelt and latch and it’s wobbly. i feel like i can tip it over. what did i do wrong?** A: This seat only allows for install using one method - Seat Belt, or Latch, not both at the same time. I would reccomend installing using seat belt - oncle you click it, pull the extra slack in the seat belt down where the buckle is, and then route the shoulder belt portion the rest of the way before you lock off - most times, the installer leaves too much slack in the lower belt and that is why it moves for any car seat. **Q: Why is this car seat not stable? it wobbles side by side .** A: Most have better luck installing this with the seat belt, over the latch system. The user manual also states, "In some vehicles in the most reclined position, it may be necessary to place a rolled towel or small blanket beneath (not behind) the Child Restraint near the seat back to provide enough recline so that the Recline Ball is in the BLUE ZONE for REAR-FACING use. NOTE: Only items approved by CYBEX are allowed under Base." **Q: Will this fit in a Chevy trailblazer?** A: Some child restraints do not fit all vehicles or all seating positions. There are so many different combinations of vehicle makes, models, child restraint configurations, seat belt designs and seat cushion designs. Dimensions of the seat H 25.5” x W 20” x D 25.3”. ## Frequently Bought Together - Cybex Sirona S Rotating Convertible Car Seat with SensorSafe 2.1, Children Newborn to Four Years, Easy Child Load, Infant Baby Toddler Preschooler, Indigo Blue - CYBEX Solution B2 fix+ Lux High Back Booster Seat, Lightweight Booster Seat, Secure Latch Installation, Linear Side Impact Protection, Reclining 12-Position Height Adjustable Headrest, Bay Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/197000321-cybex-sirona-s-rotating-convertible-car-seat-with-sensorsafe-2](https://www.desertcart.tn/products/197000321-cybex-sirona-s-rotating-convertible-car-seat-with-sensorsafe-2) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-07*
