Hi everyone, i'm sorry for my english (i don not know him), i'm using traslator. I buy "Playseat Alcantara Pro" and have a problem with the backrest. In half (where the seat is folded) there is an iron barwhich is not covered by sponge. When I sit down and support my back at that point, it's uncomfortable. It's normalor a piece is missing ? Thanks for the support.
