The protection from the seat appears excellent and meets our needs.

Isofix, strength and comfort in one!
Great grandchildren grow rapidly so upgrading their safety in the car is essential. I have professional experience of installing child seats and their comfort and protection. Adjusting seats to suit can be problematic but this seems to ok right now. It feels strong enough to protect their precious lives so seems a good buy.

Sadly, not suitable.
I had to return this chair as it is rigid and there is no recline whatsoever. So the chair will click in to the isofix but when I pushed it back, the chair does not line up with the seat back. This means either you can pull the anchor tight and have the base lift off the seat or leave it loose and there is several inches of space between the chair back and the car seat. This seems like a major design flaw. It is a shame as otherwise the quality of the chair seemed decent and it would have suited our needs otherwise.

Hi Clen,
Thanks for your query about the Harmony Genesys Harnessed R129 Car Booster Seat.
To adjust the harness strap, please push the up-front metal harness adjuster at the front of the seat, just above the adjustment strap, and simultaneously pull the chest strap towards you. The user manual contains more detail and images of the process.
Thanks for using Q&A.
Hello Sue.
Yes. The seat is designed to transition as your child grows:
Harness mode: For children 76–105 cm in height (approximately 15 months to 4 years) and up to 18 kg.
Booster mode (without harness): For children 100–150 cm in height (around 4 years to 12 years) and up to 36 kg, using the vehicle’s seat belt.
Thank you for using Q & A.
Hello Khamsa.
After contacting our suppliers they have advised for Harmony Genesys Harnessed Car Booster Seat.
The Genesys Deluxe harnessed booster will fit in most vehicles, as long as the back seat in your vehicle is equipped with ISOFIX and a 3-point lap-and-shoulder seat belt.
Thank you for using Q&A.
Hello Zoe,
The supplier has advised the following for the Harmony Genesys Harnessed Car Booster Seat:
"All R129 car seats are rated based on height alone, not weight or age. While it is always best practice to keep a young child rear-facing for as long as possible, as long as they meet the minimum height requirement of 76 cm, you should be fine using this seat forward-facing. The age reference is provided to help ensure that children do not transition to forward-facing too soon or before they are developmentally ready. Please keep in mind that the height requirement is crucial for proper harness positioning and effectiveness in securing your child safely."
Thank you for using Q&A.
