I’ve been thinking a lot about this lately. Good to find a 43T goal about it. :) I want to start doing it again; it’s probably been at least a year and a half since I used to read in bed semi-regularly or more. I do miss it.
To do:
Set up the bed and the back area more comfortably. To illustrate, the back and front areas are separated by chest-high shelves. I sleep in the back next to the shelves, where, naturally, I keep books and used to have a light for reading.

Get another alarm clock. The one I had stopped working reliably quite some time ago. I haven’t really needed one at all it turns out (I’ve almost never overslept since; I should add this to the “I have done this—worth doing” list) but it’s necessary to be “backwards” so I can see the VCR clocks out front. I can’t be in the corner by the shelf this way, which is the main reason my “reading/sleeping corner” fizzled out. (This and a habit of always sleeping with the TV on that I’ve since largely kicked. As an aside, I wouldn’t mind having a monitor and some sort of stereo in the back for those occasions when I do want to go to bed with the TV on in order to catch glimpses of games while in bed, or play tunes. It’s kind of a comfort thing I like to do on occasion. Just don’t need to do it consistently anymore.)

A good light. This I’ll likely need to build. Dim so it doesn’t light up the whole area and prevent easily falling asleep but just bright enough to read by fairly comfortably, subtle, diffuse, neutral color trending toward orange/yellow, even coverage to allow reading facing either way. Having a bright pinpoint of light within line of sight (even in the corner of my eye) is annoying and distracting. I don’t want to have to use the pillowcase as a shield like I needed to with a small light on the shelf. I.e. light on the page but not in my eyes. I’m thinking a large-ish light source a few feet directly overhead would work, that’s open to the wall above the bed and partly translucent underneath. A combination of orange, yellow and white LEDs would give off a decent color. A modification of one of those desk lamps mounted on swing-arms would be a possibility.
