noticed a bed in the hospital that had an active mattress it would inflate or deflate on one side or the other to prevent bed sores so I thought it would be delightful if i had a bed that did this in my house with many air bladders governed by some type of chaos mathematics.-- vfrackis, Mar 03 2009 Electromagnet Mattress Electromagnet_20MattressSimilar to this [hippo, Mar 03 2009] I'm not sure I understand this entirely. Do you want the bed you saw in the hospital or are you talking about something similar but different. By the way, welcome to the Halfbakery, [vfrakis]!-- Spacecoyote, Mar 03 2009 hmmmm - novel-- po, Mar 03 2009 my thinking was an ever changing bed surface maybe one that you could not manage to sleep on if you could train yourself to sleep on a surface that was engineered to prevent you from sleeping that would be something special-- vfrackis, Mar 03 2009 Ummm, what?-- colorclocks, Mar 04 2009 Sure, as long as you can turn it off.-- plasticspoon, Mar 06 2009 Sounds fun as long as you're not alone in it.-- Eugene, Mar 06 2009 random, halfbakery
