first off, many doctors give "magnet therapy" to patients who have had injuries. If magnets were that harmfall they wouldn't be considered a good form of therapy. Though between you and me, magnet therapy is typically for someone who has nothing wrong with them except in their head, so that's the treatment and they think it helps fix the problem.
ANYWAYS, sounds great, but what can the house be made of? I mean you can't have a carpet because the staples would be ripped out, and nails, that'd be no good either. So basically you need a special house for it.
AS for the table, not such a good idea, putting your legs underneath it. I wouldn't put anything underneath it and interrupt the magnet flow. Oh, there's another problem, what about storage space under the bed? Or bunk beds? Can you have a magnet bed floating over another magnet bed?
