A Bed That Morphs Into A Wheelchair

Panasonic has created a bed that morphs into a futuristic wheelchair. But get this, due to possible legal and liability issues, the bed will not yet be marketed. This is an amazing product which will be of great use to severly disabled people. I mean for people who require lifts, this will be a godsend. I don't understand legal issues which prevent products like this from coming to the market.
