So I'm stuck... my car has a back anchor point and so, in theory, I could buy any seat and it'll fit. However the anchor point is, strangely, so high up the back of the chair, that the seats I've tried will not let me lock tight (green light) the strap - in other words, the angle of the strap coming over and the big bulky mechanisms they have sit in a way, at the top of the bac of the seat so as to not allow me to lock tight the strap.
I'm left looking for ISOFIX seats that have the leg - rather than the strap - as they're extra support. All Group 2/3 ISOFIX seats seem to have the back anchor straps. Does anyone know of a Group 2/3 with a leg instead?
