That's why the lazy-boy style armchairs are so popular - lie out flat on your back and look up

Seriously, I'm considering putting a flatscreen on a wall above a new fireplace. Been looking for a low fireplace/mantlepiece (<900mm) so as to avoid the neckache problem. There's not much choice around, but there are a few. I'm also thinking that I've got to mount a centre speaker beneath the screen (forcing the screen up), but I suppose I could put it above - if it doesn't look too odd...
