If you thought blasting your iPod was bad for your ears, you ain't seen nothing. The sonic bed is a king-size bed with 12-channel surround sound. It may look like a wooden tank from the outside, but inside its got enough speakers to dwarf any home theater set up. Created by Kaffe Matthews as a museum exhibit (no plans for retail as of yet), the bed requires 220 volts of electricity and covers every inch of your body in sound. Throw in a flat-panel TV and we'll never leave bed again. Click on for some pics of how the bed was made.
