If you're looking for more fun in the sack here is a cool bed for ya.
The Akva Sound is a waterbed with built-in loudspeakers that utilize the water's unique properties as a carrier of sound and oscillation. It promises you an intense feeling of being right where it all happens while watching a movie (don't watch a scary movie!). Great for those who like t watch movies in bed. The music bed can be used effectively in therapy. Put on some nice music and feel the vibrations through your whole body.
The Akva Sound consists of a special base plate for mounting loudspeakers inside the bed. The base plate is available as an accessory or as an integrated part of the waterbed.
