Car seat up to 105cm - 18kg (Poynton Sk12 1qb)

Cybex Sirona S i-size car seat.
Can be used up to 105cm or 18kg (whichever the child reaches first). User guide included.
Only usable with cars that have isofix system.
It used to rotate at 360 degrees but it’s a bit stuck, so it doesn’t always go rear facing.
Well used car seat but could still be useful in a second car or for the grand-parents and other carers’ car.
Any questions let me know.
