Seat back panel removal

Hi , looking to clean cushions etc in Adria izola 687 but can't figure out how to remove back panel behind side seat and behind table double seat . No screws etc to be seen , are they glued in ?

No tried gentle persuasion but no joy

I seem to recall that on one of our caravans, many years ago, the seat backs were held in place by two flat strips of metal which were fixed to the seat back by screws. The metal plate was formed so that the lower part was bent to be slightly proud of the part that screwed into the seat. On the wall of the van there were two receiving plates. Each was screwed at either end, but the middle was formed to allow a gap. The seat was slotted into these by offering up the back, but slightly higher than final position. As the back was lowered, the metal strips engaged. To remove, the seat back was moved vertically upwards.
Worth a try.

I tried to remove ours to change the tired looking leather cover, but after many attempts I gave up it is stuck to the wall panel behind it and I fear to much force will lead to more damage, so have left it alone
