DH and I always brought my MIL a nail apron, just the cheap canvas ones, from Home Depot. We loosely tied the apron to the bed rail. It was great for putting chap stick, lotion, a pen etc in the pockets.
Someone gave me a shoe holder that tied at the top to hang over the bed rail, and filled each holder pocket for me when I was in the hospital in March. They put:
crossword puzzles, word search books
packages of fun pens, notecards
chapsticks
trial size lotions (no scents)
Itunes giftcard
coloring books and crayons (that was actually a fun, mindless thing to do)
handheld games (Tetris and Battleship)
fun, novelty socks
fuzzy slipper socks
manicure kit with tweezers (this came in SOOO handy!)
toothbrush and trial size mouthwash and toothpaste
lots of mints, gum, hard candy, suckers to help with nausea and dry mouth
small compact mirror
hand sanitizer
change (great to give the kids to go get a soda from the vending machine when they came to visit)
I'm sure there was more. I just can't think of what else was in there!
Also, someone brought me a huge fuzzy blanket. It was so nice to curl up in that instead of the stupid scratchy hospital blankets.
