We have a 1984 e35 mk III. I think we've tried every combination of cushions to make up the bed using the table settee area. Maybe I've missed something. Some are too big, some too small. Nothing seems to fit over the table top perfectly once it is lowered to the right position. Is there a special cushion for this that our boat is missing, or what's the right combination? My crew's getting cranky with the lumpy bed!
