Arguably one of the most useful sexual devices on the market, the Bonker truly has hundreds of uses. The Original Bonker positioning system consists of two half-a-heart-shaped arms that attach to wide rectangular bases designed to fit between a mattress and box springs effectively anchoring the system in place. Each arm rises up alongside the bed to tower overhead and act as the pivot point for all of the various straps and attachments included with the unit. Each unit is accompanied by a DVD user's guide illustrating many positions and suggestions for use. Unique distinction is given to the Bonker for enabling physically disabled individuals to achieve comfortable sexual positions.
