The Under The Bed Restraint System is a must-have for adventurous, bondage-loving couples. Designed to be incredibly user friendly, you can slide the straps under the bottom of your mattress either from top to bottom or side to side (not to mention combinations of the two) to customize playtime perfectly.  Sturdy nylon tethers connect to 4 snug, softly lined cuffs, one pair for the wrists and one for the ankles- they hold your object of desire securely in place.
