There are several advantages to the exemplary Under the Bed system and none more so than its convenience. Because it straps discreetly beneath the bed, there is no need to unhook everything when it's not in use. When necessary, just slip the cuff ends between the box spring and mattress. Otherwise I like to leave it out as a reminder to the girl that she'd better behave. Comes with four 60-inch straps and one 60-inch connector, all of which is remarkably simple to set up. For those into bed bondage, this is one of the finest purchases you will ever make.
