While ours are not in a slide, thus I had a flat floor to work with, I decided to replace our dinette with theater seats that recline:

These need to be set about 3 1/2 inches from the wall, leaving a bit of space behind that can be used as storage. It's a bit difficult to access, but hey, that's part of the fun!
For installation into a slide, I've seen kits to install rollers on the front bases.
