Sei Mio The Bottom Line Under Mattress Restraint System gives you a versatile bondage setup without drilling, hooks or permanent bedroom fixtures. The adjustable strap slips beneath your mattress and stays hidden until you are ready to play, so your bedroom looks exactly the same to everyone else.
Six D-ring attachment points let you create a wide range of wrist and ankle positions, from a classic spread-eagle to more creative arrangements. Plush cuffs are included, so you have a complete restraint setup straight out of the box with nothing extra to buy.
Built from metal, nylon and polyester, the system pairs sturdy hardware with durable webbing. The strap adjusts to fit most mattresses, including king and super king sizes, making it a practical choice for almost any bed. When the session is over, simply tuck the straps beneath the mattress for discreet storage.
