This bed stand holds the iPod touch 5th gen but will also hold all other iPod touch models and the iPhone 5 (the 4/4S is too thick). The iPod is held at a 45 degree angle about a foot from your face, which I found to be perfect viewing distance for me. It is held onto the backboard of the bed by 2 pieces of wood which fit snuggly onto it. (See picture 3)
The arm is supported with 2 support beams which have the actual holder itself on the end. The holder has two rails which hold the iPod in place. These rails had to be accurate as I wanted minimal coverage of the screen, so each rail goes over the edge of the iPod by a mere 1mm. (See pictures 4 & 5)
Please note: I had to record this with my iPod as I currently have no working cameras so at the moment no pictures with the iPod in the stand can be taken. I will try to get a new camera soon.
Here is a video showing more views and angles of the stand:
