Under Mattress Restraint System — Shadow Anywhere You Dare by Sportsheets

Under Mattress Restraint System User Guide & Play Styles

Using the adjustable bondage restraint system for next-level couples play

Confident couples already know the basics — this Sportsheets couples restraint system is built for those ready to go further. Slide one adjustable strap across the head of the bed, the second toward the foot, and use the D-rings to lock in exactly the positioning you want. The black nylon-blend straps hold firm under mattress weight, so you stay focused on each other, not on the hardware. For a deeper look at technique and dynamic, explore our guide to bondage sex before your next session. Clean the straps and cuffs with a damp cloth and mild soap after play — body-safe maintenance is part of the experience.

Taking the under mattress bondage system beyond the bedroom

The Shadow system’s adjustable design isn’t limited to the bed. Drape the straps over a chair back, a hotel ottoman, or any firm surface and the gate clips handle the rest — making this bondage strap system a genuine travel companion. Sportsheets built this for couples who refuse to let geography limit their play. Pack it flat in a suitcase and it disappears completely; set it up in under two minutes wherever you dare.
