We don't have a slideout in that location. We also have a standard dinette.
I upgraded our cushions direct from our RV manufacture. We went from cloth covered regular foam, to leather covered memory foam. The memory foam is a little thinner but much more comfortable. The thinner backrest also gives us more seating surface and leg room. The rear bench faces toward our TV. One of us will sit there, the other on the 3rd captain seat. Though not "ideal for watching TV, the dinette does work for watching TV better now after the cushion upgrade.
We love our dinette for it's intended purpose and also for bulk storage. We would never buy a motor home without a booth dinette.
Here is our dinette and TV watching.
