This comes my way via Firearm Blog:
We have seen some methods of storing shotguns within reach while in a bed. This one is rather clever. It drops from a hidden panel inside the headboard. The mechanism can be tuned using stiffer springs to prevent accidental activation. I would hate to be stretching as I wake up and have a shotgun drop onto my face.
For more information or to order one go to the Gunbed website.
