Fabulous idea. With a thicker, more cushy mattress.... I would never leave. How about a simple single 'shelf' / 'end table' along the entire length of the bed on just one side to accommodate my books, magazines, drinks and snacks? While I'm dreaming, I might as well dream big.
Create your own pass-through window. If your kitchen window opens onto a deck or patio, why not turn it into your own private bar? A counter and stools tucked right up to the window make it easy to pass drinks and snacks right from the kitchen
