La-z-boys are deathly unfashionable, compared to more minimalist designer furniture, but goddamn are they comfortable. I got two of the heating vibramatic lumbar-balloon-thingy chairs a couple years ago, and they're awesome. No fridge in the arm, I think that's a little *too* lazy, even for me.
Bummer you can't sleep horizontally, but cool that you got a good chair. Have you considered a bad that can fold up? My uncle couldn't sleep flat for a while and got a Tempur-Pedic (expensive foam) mattress with remote control head & knee raisers, plus minor vibration massage. I slept on it a couple times and it was pretty nice, made me a bit too warm but it's a nice mattress.
