As of 13 August 2026, AI can only partly choose a child car seat.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open GOV.UK guidance on child car seats and note the rules and terminology that apply to your journey.
   2. Gather your child's current height and weight, the vehicle registration or exact make, model, body style and year, and the seating position where the seat will be installed.
   3. Check the vehicle handbook for ISOFIX points, top-tether points, approved seating positions and any restrictions on child seats.
   4. Paste those details into the prompt, then ask the chatbot to separate verified facts from assumptions and missing information.
   5. For each shortlisted model, open the manufacturer's current product page, manual and vehicle compatibility list and compare them with the chatbot's claims.
   6. Contact a retailer or fitting service that offers physical child-seat checks, take your vehicle and child seat if possible, and confirm that the seat can be installed correctly in the intended position.
   7. Buy only after the physical fit and the manufacturer's instructions agree, then install it yourself exactly as instructed and repeat the check whenever the seat or vehicle position changes.

   Prompt

   Help me choose a child car seat for use in the UK. Do not make a final safety decision from assumptions, and do not invent product specifications, approval details or vehicle compatibility.
   
   My details:
   - Child's age: [age]
   - Child's height: [height]
   - Child's weight: [weight]
   - Vehicle make, model, body style and year: [vehicle details]
   - Seating position I want to use: [position]
   - ISOFIX available: [yes, no or unknown]
   - Budget: [budget]
   - Need to move the seat between vehicles: [yes or no]
   - Other needs, such as a newborn fit, compact size or easy removal: [needs]
   
   Explain which information is missing. Then give me a shortlist of suitable seat types and specific models only where you can point me to the current manufacturer compatibility information. For each option, state the child's permitted size or weight range, the approval or standard information shown by the manufacturer, installation method, seating-position restrictions, advantages, drawbacks and what I must confirm before buying. Distinguish clearly between verified facts, information I still need to check and your general explanation.
   
   Use current UK sources where available, including the manufacturer's manual and vehicle compatibility list, GOV.UK guidance and an established retailer's fitting information. Tell me to arrange a physical fitting check if compatibility or installation is uncertain. Do not claim that a seat is safe merely because it is popular, highly rated or listed online, and do not tell me to ignore a vehicle or manufacturer instruction.
