Sei Mio The Bottom Line - Discreet Under Mattress Restraint System
Description
Turn almost any bed into a versatile bondage restraint system with The Bottom Line by Sei Mio. This discreet under mattress restraint strap sits beneath the mattress, keeping the setup hidden until you are ready to play. Six D ring attachment points give you the freedom to secure wrists and ankles in a variety of positions, from a simple arms apart arrangement to a more restrictive full body setup.
Adjustable webbing creates a secure foundation beneath most mattresses, including king and super king sizes. A set of plush wrist and ankle cuffs is included, while nickel free hardware provides dependable connections. Change the attachment points to keep limbs apart, raise the wearer's position or create a tempting angle for teasing and impact play. It is an easy way to explore bedroom bondage without permanent fixtures taking over the room.
