DS1 (6 in September) finds his Graco booster seat like this one but I paid twice that !
After about an hour he complains he has a sore back.
I've bought an extra neck cushion but that doesn't seem to help.
I could buy him another, but with no guarantee he won't find it uncomfortable too for long journeys.
We often drive long distances for holidays so need something comfy for him.
Thanks
