Our 2015 Cyclone 3110 is the same way, and the bed is not in a slide.
but, walking around the end of the bed to the RH wall to access the RH side of the bed is so tight that I can only conclude they decided to shorthen the bed platform length to make it easier to squeeze through by pushing the mattress out of the way to get around the end to the corner....
Not nice, but when space is short something has to give to provide all this luxury! and your feet really do'nt need all that support!
