And here’s the one for the other side, with an additional bed side shelf.
(Actually the whole bed is customised, I’ve made it longer and added the side panel to hold up regular books.
Then there’s the iPad in the bath support. I’m paranoid about knocking the iPad in the bath, so the rubber bands hold it tightly to the support and the support is cut to fit the bath rack so it can barely move.
Nope - far too slippy and in danger of falling on your own head when you fall asleep .
The freestanding one for the middle of the bed has an 8 inch base, so it is quite stable. For the bedside, if you can’t hook it onto something how about a board that goes down the side of the mattress? Shaped like a shepherds crook in profile… TBH the whole reason for putting in the side panel on the bed was to prop up books and ipads.
