We have just got a lovely Mercedes Viano but the Rock and Roll bed opens OK but is difficult to close. There is a 'Push ' leaver which seems to be working OK but the bed doesn't move upright. Any ideas as to how to make it easier please?

Hello my name is John and my wife and I have just got a Mercedes Viano camper. Done a lot of camping when the kids were young but this is an adventure we are both looking forward to new experiences.
