Could have been five
Unfortunately the knob on the left isofix fell off the first time I installed the seat . Should have returned it he seat but needed it immediately . Still useable but more difficult to install and remove.

Light and value for money
I bought this 2 weeks ago and so far I am very pleased with my purchase, it is very light to carry around and value for the money
Chris, 25 - 34, Manchester
Highly recommend!
Really impressed with this car seat. Had to changed car seats for my 3 year old due to breaking her old one whilst trying to take the cover off to wash. This Harmony one looks really simple to detach the cover when comes to washing. Looks comfortable, well padded, easy to fit, and very easy to slacken the straps and tighten when needed unlike her previous one. Fits all the guidelines for a recommended car seat and will last till 12 years old. Only downside is that is that it does not recline very much, but isn't really an issue for me as my toddler is starting to sleep less in the car. Planning to purchase another one for when my 2nd child is of the age/size requirements to fit this seat.

Hi, the Phoenix Deluxe is a forward-facing harnessed car seat for children minimum of 15 months old or at least 76 cm in height. Thank you for your question.
Hi there,

Thanks for using Q&A,
Hi KA, the lap portion of the vehicle seat belt is threaded over the childs lap when using the Phoenix Deluxe as high-back booster Group 23. The Phoenix Deluxe requires the use of Isofix and Top Tether only without the vehicle seat belt when installing the seat in harness mode Group 1. Please contact us at customerservice@harmonyjuvenile.com if you need more assistance. Thank you for your question.
Hello KA,
The supplier has advised the following for the Harmony Phoenix I-Size 1/2/3 Car Seat:
“ As this is an R129 seat it is only tested and approved for use with the Top Tether and Isofix connectors in harness mode (Group 1). ”
Thanks for using Q&A.
Hi Nixon, thank you for your question! Simply turn the recline adjust knob in front of the seat base clockwise to recline the backrest until the backrest lies flush on the vehicle seat back. You may need to remove your vehicle headrest if it gets in the way of your child restraint from lying flush against the vehicle seat back. Please use the recline that allows for the best and tightest installation. Please contact us at customerservice@harmonyjuvenile.com if you require further assistance!
Hi Nixon,
Thanks for your query about the Harmony Phoenix I-Size 1/2/3 Car Seat.
Having checked to see, it has a knob at the front of the seat that you turn to recline it.
Thanks for using Q&A.
