I'm a full-motion waterbed guy.
I could have anything I want -and that's what I want.
In the winter adjust the temperature up a little and it's always pre-warmed,
In the summer turn it down and all night it's cool and crisp.
The dog is a big fan of the heated waterbed too!
If Duke could figure out how to get his food and water bowls up there he's only get off it to poop...
