I have jumped on our bed. It's fun, but I don't do it much. I prefer bouncing on it.
Anyway, yesterday I jumped on it to get to the phone. I was like a ninja ...run..jump..land...bounce...slide. And I missed the call, but it was fun.
As for rotating and flipping the mattress. I try to keep up on that, but it's a pain. The only time I'm in bed is when we're going to bed at night. Sometimes in the middle of the day, but no sleeping happens then.
