2014 Georgetown XL 377 -- the bedroom foam mattress sinks in the middle causing the sleepers to roll to the center of the mattress. I reinforced the board platform the mattress sits on with angle iron so the wooden plywood board would not sag. But the mattress still sinks in the middle.
Looking to replace the mattress. Has anyone had this problem and what was the solution? If you replaced the mattress what mattress did you use for a replacement and where did you get it? I would appreciate any information. Thanks!!
