Wunny,one of my correspondents,has done us all 440/4 owners a big,big favour by sending me a description of how to make the rear bed up in the 440/4 without the triangular cushion falling on the floor.
This was discussed on the blog a while ago,here is what he has said ( with photo's) :-
For new readers, the solution to this problem is to move the forward seat
cushion to the table and the 'triangular' (trapezoid) shaped cushion goes onto
the forward seat, such that it held in by the seat side panel.
the rest of the bed with other cushions as appropriate. The small back rest
wedge goes in the bottom left hand corner.
Manny thanks for that Wunny,especially the pictures,much appreciated.
