I think I have what is very common with Autotrails ... Both seats have swivels, but I cant actually swivel them all the way around as the lever that releases the swivel fouls on the side of the sofas, so while there would be room for the seat to turn 180 degrees and you could even have your legs down and probably be perfectly comfortable, it is just not possible to achieve it. (and there is scraping of the wood veneer on the board to indicate that fouling multiple times!).
Doesn't bother me that it can't be done - but it is annoying having the damage to the board though. Autotrail should have added some kind of stop to prevent that happening.
