I've had the cabriofix and can easily loosen and tighten the straps. So I'm thinking the priori must have the same mechanism of loosening the straps. But I can't find a button to press to release them!! I really struggle to buckle him in and it would be so much easier if I could buckle him in with the straps loose then tighten them once he's in the seat, like I do with the cabriofix.
Could anyone help? Thanks in advance.
