Sei Mio The Bottom Line Under The Bed Pillory is a discreet under-mattress restraint system that turns your bed into a versatile bondage setup without permanent fixtures, drilling or bulky hardware. Designed for couples ready to move beyond basic wrist cuffs, it delivers a complete restraint kit in a single purchase.
The adjustable main strap slides beneath most mattresses, including king and super king sizes, leaving six D-ring attachment points positioned on top of the bed. Those points support a wide range of wrist and ankle positions, from a classic spread-eagle to more creative arrangements, so you can change the scene as often as you like.
Plush wrist and ankle cuffs are included, offering a comfortable hold for longer sessions. The system is made from polyester, nylon, metal and PVC with nickel-free hardware, and the adjustable webbing tightens for a secure fit. When playtime is over, the straps stay neatly out of sight beneath the mattress.
Setup takes moments: slide the strap under the mattress with the D-rings on top, tighten the webbing, then attach the cuffs to wrists and ankles. Experiment with different connection points and check the fit regularly for comfort.
