The Sportsheets Edge Extreme Under the Bed Restraint System transforms any standard bed into a secure anchor point for restraint play in minutes. Unlike bulky furniture or wall-mounted hardware, this system slides invisibly beneath your mattress — the nylon webbing straps remain hidden while six connection points emerge at strategic positions around the bed frame. The adjustable centre strap slides vertically along the mattress length, letting you reposition mid-scene without reinstalling the entire system.
Each connection point uses a push-clip attachment that pairs with Sportsheets' universal cuff system (sold separately) or any restraint with compatible hardware. The straps accommodate mattresses from twin to California king and work with platform beds, box springs, and adjustable bases. Setup requires no tools — thread the straps under your mattress corners and clip the centre strap to the desired height. The system also adapts for door use by looping the straps around a closed door frame, though bed installation remains the primary design intent.
This isn't a beginner wrist-tie kit — the Edge Extreme targets experienced couples who want repeatable, stable restraint without visible bedroom modifications. The webbing won't slip during active play, but comfort depends entirely on the cuffs you attach (padded neoprene recommended over rope loops). If you're new to restraint play, consider starting with the standard Sportsheets Under the Bed system before upgrading to this six-point configuration.

How to Use
Thread the four corner straps under your mattress corners, positioning the clips at the bed's edges. Attach the adjustable centre strap to the desired height along the mattress. Clip on compatible cuffs or restraints (sold separately) and adjust webbing tension by pulling the straps taut. To remove, unclip restraints and slide the system out from beneath the mattress — the straps can remain installed between sessions. For door use, loop the corner straps around a closed door and secure with the door's weight.
Frequently Asked Questions
What cuffs work with the Edge Extreme restraint system? The push-clip connectors fit Sportsheets' universal cuff system and most restraints with compatible snap-hook or carabiner hardware. Cuffs are sold separately — neoprene-padded options provide more comfort than basic rope loops.
Will the straps work with an adjustable bed base? Yes — the webbing accommodates adjustable bases, platform beds, and box springs from twin to California king. The straps flex with mattress movement but may shift slightly during extreme angle adjustments.
How do I clean the webbing straps? Spot-clean the polypropylene webbing with mild soap and warm water, then air-dry completely before storing. Avoid machine washing, which can weaken the stitching at stress points.
Can I leave the system installed under my mattress permanently? Yes — the straps are designed to remain beneath the mattress between uses. The clips stay accessible at the bed's edges while the webbing conceals completely under the mattress bulk.
Does the Edge Extreme restraint system ship discreetly to Canada? Yes — every order ships in plain, unmarked packaging with confidential billing.
