Under Bed Restraint System — Edge Extreme by Sportsheets

Under Bed Restraint System User Guide & Play Styles

Setting up the advanced bed bondage system for your first scene

Slide the flat black nylon straps under your mattress so the cross-point centers beneath the bed — the whole process takes under five minutes. This nylon restraint system works with any mattress size, so there is no measuring or guesswork involved. Attach compatible cuffs or a collar to any of the six connection points, then slide the adjustable middle restraint strap to the position you need. Agree on a safe word before play begins and keep safety scissors within reach — standard practice for any bondage session, whether you are new to restraint or well past beginner territory. When the scene ends, the system stores flat and invisible. For a broader primer on restraint play, read our guide to restraining your partner.

Using the couples bondage restraint system during partnered play

The Edge Extreme under bed restraint system shines in couples power-exchange scenes where positioning control is everything. The adjustable middle strap lets one partner fine-tune reach in real time, keeping the scene fluid without breaking momentum. Because the black nylon hardware sits completely hidden under the mattress, nothing signals “dungeon” to a guest glancing into the bedroom. Sportsheets built this system for couples who revisit this kind of play regularly — the durable nylon webbing and push clips hold up session after session.
