Hollandia International’s Executive Safe-T bed has a heavy-duty safe underneath the mattress and a cover in the head joint of the bed base. The bed was originally developed for a wealthy international customer who wanted to keep a handgun close by at all times. The safe can be added to any Hollandia bed for $400, but the beds themselves can run in excess of $20,000. As an alternative, you could always pick up a pair of skid marked security briefs for around $6.”]
