We have found a way to use our dinette as a semi-recliner -- we have these long thin "body pillows" that we use when we are sleeping. When the dinette is set up as a table, rather than a bed, we fold the big pillows in half, place them against the upright end of the bench, and stretch out sideways on the bench seat. It's actually very comfortable!
But a real recliner would be a lot better, especially if you plan to sleep in that position all night long.
Anyway, for whatever it's worth, here is an "action shot" in which we are actually using those pillows to recline, just after dinner. If it looks like we are dressed up like Siberian peasants, that's because this was taken while we were snow camping in Sequoia National Park:
