3 x near new baby car seats (Gidea Park)

3 seats but take which you want or all. 2 ABC tulip group d and one Ikklebubba. One ABC and the Ikklebubba are suitable for newborn up to ? 15 months. The other ABC is from 3 months up. They were bought by my daughter but she could not fit 3 babies in her car so have been used ? 5 times and have had no knocks or bangs etc. Condition is nearly new. Babies are now too old to use. They fit using the car seatbelt but I understand they could be used isofix if you bought the right adapter fitting. You would have to research this.
