Our Flux Isofix eXT is the perfect combination of safety, comfort and flexibility. The flux ext is currently the only harnessed high back I -size booster that allows your little one to be harnessed up 120cm ( approx. 6-6.5 years ). The i-Size child car seat offers a 14-position heightadjustable headrest, a removable padded seat insert and an automatic 5-point harness system that grows with the child. It is suitable for small passengers up to a height of 120 cm and a maximum weight of 23 kg. The magnetic holders for the shoulder straps create additional comfort when getting in and out. Alternatively, it is possible to switch to convert the seat to high back booster mode with the vehicle’s 3-point harness from a height of 100 cm; the 5-point harness can be easily stowed away in the child car seat. An extra feature on the seat: Special protectors on the headrest provide increased side impact protection and make travelling in the Flux Isofix eXT particularly safe. In addition, an integrated sensor in the seat assists in the correct installation of the seat. Incidentally, the Flus eXT can be installed using Isofix in combination with top tether and, from 100 or 120 cm, with the vehicle's 3-point harness.


  • Easy and safe installation with Isofix and top tether (76–120 cm), currently the only high back harnessed R129 booster with this feature.
  • Special feature: Integrated sensor for correct installation (battery operated)Optimal belt run due to belt guides for the size class 100–150 cm
  • Automatic 5-point harness system for children up to a height of 120 cm and a maximum body weight of 23 kg. This is a great feature of this car seat as some children maybe over 105cm but under the weight of 23kg and parents would be happy to be able to still harness their child in the car seat using the 5-point harness of the car seat.
  • Easy to use with magnetic holders for shoulder straps
  • Special side impact protection through enlarged side parts and protectors on the headrest (SIPS PROTECT)
  • Additional slide protector for increased side impact protection
