  "answer": "No checked fact states that any of these seats has a steel frame. The closest safety facts for each seat are listed here. CYBEX (listed by the store as Cybex-dc) Sirona S: The maker claims the Linear Side-impact Protection reduces collision forces in a side impact by up to 25% and the load leg reduces frontal crash forces by up to 30%, compared with the same seat without those features. Graco SlimFit 3-in-1 Narrow All-in-One Convertible Car Seat: Testers report the SlimFit had some of the best crash-test sensor results in their comparison, with low HIC and chest-clip forces. PEG Perego Primo Viaggio Kinetic Convertible Car Seat: The video names kinetic pods for extra safety, breathable fabric, and the anti-rebound bar spacer as pros.",
