Hello. I need to by the stage 3 booster car seat for my son. Its the one that is for ages 6 upwards and is just the base lifting the child high enough to use the car's own seat belts. I have looked at various ones online including amaxon, halfords, mothercare etc but there is not much choice and I felt the ones in halfords and they seem very hard to sit on and pretty basic (i think they were Graco ones).
Can anyone recommend a quality, comfy booster car seat please? Preferably with cup holder but not essential. I have realised that the ones my son's friends have are mostly ones that were part of a larger combination car seat stage high back booster seats and they seem to be much more cushioned and comfortable that the ones you can buy just as booster seats.
Many thanks!
