Taking out a dinette and putting in a nice recylner and more

I would like to get rid of the dinette and couch. Both are terribly uncomfortable (it is 18 yrs old). I would like a recliner and new sofa. We don't really use the table, it's a clutter catcher. Plus with my bad back the only place I can sit is the bed. So I spend a lot time in bed. I did by a lawn chair rocker just so I could have a comfortable place to sit.
