What are carseats made out of?

Car seats are primarily made from a combination of materials, including a hard plastic shell for structural integrity, foam padding for comfort and safety, and various fabrics for the cover. The plastic is typically high-density polyethylene or polypropylene, which provides durability. The foam is often polyurethane or ethylene-vinyl acetate, designed to absorb impact. Additionally, car seats may include metal components for reinforcement and safety features.
