Thanks for the replies!
From those and the advice of the service writer instead of buying a direct replacement we went to a local furniture store, with our dimension limitations in hand.
We purchased a Violino 3 seat leather couch (power recliners at each end) and matching leather power recliner chair (back ordered).
I built a narrow end table for between the couch & side wall of the slide out.
I made the base wider than the top so we can reach the power controls on the side of the couch.
We have another small end table for between the couch & recliner.
Yes we lost a seat & the massaging vibrators but we really don't care about that anyway.
Hopefully the new leather furniture will last longer than the four years of the el cheap o vinyl original furniture!
Thanks again to those who provided input!
