Russell's observation on the effects of rocking motion during sleep is backed up by scientific studies done in Switzerland by Geneva University Hospital as well as pretty much anybody with a baby.

The Rocking Bed comes with legs and can be used as a base for your mattress. It can also replace a box spring and sit on your current bed frame. The rocking motion, controlled by a timer built into the the unit, ramps down the movement as the time ends. I like that the bed isn't dependent on a phone to control it. It's all about unplugging from the world and falling asleep faster.
