just managed to fit the Z hinges at last. All went well after taking the propex out, which was in the way. No heat now, but it’s summer . That’s another job , later. But it’s not quite there back cushion doesn’t stop on anything when it’s a seat., and when it’s in bed position the back cushion sinks a bit too much. Hoping these extra bits are something to do with this , but can’t work out where they go? Any ideas?
