This is a photo of the Amby next to our bed. (click for larger version)

It is basically a free-swinging padded hammock. Among others, this is recommended by Dr. Sears. It keeps the baby near by, and helps eliminate things like the flat head you sometimes get from a crib. Also, since it is free-swinging, the cats want nothing to do with it :-)

The heater vent under it will likely be closed off during use.
