Report "I have bought a used quinny buzz - although is pushchair is in fab condition I havent got the first idea how to use it - is there anywhere I can download the user manual? Can the seat cover from the first stage seat be changed or even be taken off to be washed? Same with the shoulder straps can they be taken off for washing? I am having another baby and want to keep the foam seat for the newborn but i think the covers would need repalcing is this possible ?"
