Secure Under-Mattress Bed Restraint System The Bad Kitty Bed Shackles Set transforms any bed into a versatile restraint station without requiring posts or headboards. This complete system features adjustable straps in vibrant colors that anchor securely beneath your mattress while keeping restraint cuffs accessible above. The under-mattress design means no visible hardware or permanent installation—just slide the straps into position and you're ready. Each kit includes four adjustable cuffs connected to extra-long straps that extend from all four corners of the bed. The straps feature secure buckle closures and slide easily under mattresses of varying thicknesses, from standard twin to California king sizes. The colorful strap design adds visual interest while the black neoprene-style cuffs provide comfort during extended wear. Comfortable Restraint Cuffs The padded wrist and ankle cuffs are constructed from soft, skin-friendly material with a smooth interior lining that minimizes chafing and pressure points. Each cuff fastens with a hook-and-loop closure system that adjusts quickly to accommodate different sizes while maintaining consistent hold. The generous width of the cuffs distributes pressure evenly, reducing the risk of discomfort during active movement. Metal D-rings on each cuff allow for secure attachment to the bed straps via sturdy metal clips. This hardware is designed for reliable connection while remaining easy to release when needed. The cuffs can support a full range of motion within their restraint radius, making them suitable for various positions. Universal Bed Compatibility The adjustable strap system accommodates beds from twin to king size without requiring modification. Each strap extends long enough to reach under even thick pillow-top mattresses and tuck securely on the opposite side. The flat webbing design prevents bunching or shifting during use, maintaining consistent positioning throughout your session. The colorful straps—featuring alternating bright hues—make setup intuitive by clearly distinguishing each corner's attachment point. This visual coding helps ensure proper placement and balanced restraint positioning.
