Hi there I've just bought a triple bench seat to start the process of converting my T5 panel van. It was already folded up when I went to pick it up so just hoisted it into the back of the van to check out later on. Being new to all this I can't for the life of me work out how to unfold it!! It's not only folded flat but also moved forward like when you unattach it from the rear hinges (I've only seen this in pictures and not talking from experience!). Looked online but there's no answer that I can I guess because it's quite basic knowledge but not to me Question is how does it unfold? I've tried pulling all the straps I can see but to no avail...please help! Picture attached.
