Weirdly true. A year ago, I bought perhaps the most comfortable chair I've ever sat in specifically for the purpose of reading. And it really is incredibly comfortable to sit in. Yet ... it doesn't solve either of the two central problems of actually reading: having to hold the book/ereader and the head/neck/shoulder angle. The only solution I can imagine is an "overhead" mounted ereader with voice control, and I don't actually want that.
My Apple Vision Pro is perfect for this, especially with the dual knit band. It really helps me just focus on reading as well, unlike a laptop or something where alt-tabbing is super easy and the (enlarged) book isn't taking up most of my FOV. It's an expensive solution, though, and not for everyone (for example my wife's neck is way slimmer than mine and it would injure her over time).
(And the pinch the page to turn it like a real page is the most fun thing in the Apple Books app).
Tablet/kindle on an arm mount (the kind with springs like a microphone or architecture lamp stand works best, goosenecks fail pretty quick), and the wearmouse app on an android watch to turn pages works pretty well.
