I'm looking to source a high-quality car seat designed for children from birth up to approximately 12 years old, accommodating heights between 40 to 150 cm. The car seat must conform to the ECE R129/E4 certification for safety standards, ensuring it meets rigorous testing requirements. In terms of installation, I'm specifically interested in models that use ISOFIX with a top tether for enhanced stability. Additionally, the car seat should offer both rearward and forward-facing orientations for versatility as the child grows. A compact design with dimensions around 44×53×81 cm would be ideal for fitting into various vehicles. Please provide details about your available products that meet these specifications.
