Following short-term use of the viewers lounge in its incomplete form, a few tweaks were made to the design, which now includes a back-rest that doubles as a small library, and relocation of the AC and DC power sockets for more convenient access...

I started with a basic box, drilled a finger hole with a hole saw and re-purposed a previously-broken backrest as a shelf.

This box was measured to fit my notepads, since I write a lot on the road, and wanted a convenient place to store them. The box will be attached to the back of the new viewer's lounge seating, providing a back rest (cushion to be added later).

One of the new seats. Wider and more attractive, and with additional storage compartments.

And since the box is located more or less in the center of the living space, and on the same unit that the power sockets are built into, it seemed like a good time to do some refactoring in the electrical department.

After removing the sockets from their previous location, I just drew around them and cut new inserts in the side of the new book shelf.

That's the AC power outlet sorted. It runs on circuit 3, from the inverter, providing 230V power for household appliances (not that I have many, but it's useful when its useful).

That's the DC power outlet that runs on circuit 2, providing switched power from the charge controller, to run hungry DC devices like chargers, and the ever-useful dustbuster (dog hair doesn't take a day off).

Testing the socket before sealing it off.

Minimal wiring, routed down to the floor trunk via the viewer's lounge seat.

Since this box will have books inside, it's necessary to cover the wiring to prevent it from being damaged or interfered with by moving objects. And since there's electricity, it doesn't hurt to have a warning about it. I just cut the previous strap to fit the width inside the box and glued the off-cut underneath it to fit the height.

If you notice, in the first image, the door of the box has a strip on the right side which is separate. That makes the door narrower, allowing it to open and close without being blocked by the arm rest. I since did the same on the left side to cover up the electrical portion, and it gives the unit a more balanced look.
