vinyl upholstered daybed makes a great place to lounge and hang out with friends. Antique chair and nightstand are painted for a fresher look. Vintage chrome lamp and new flokati rug enhance the retro feel of the room.
Then the upholstered 3' or 4' high tufted panels can be made the same size as the side and end of the bed and attach them to the walls, above the baseboard.
Call an upholsterer for sure.... you probably know one. They are usually quick too.
