The Lovetoy Rebellion Reign Under-Mattress Restraint Set is a beginner-friendly bondage kit built around four adjustable nylon straps that tuck under a mattress or other furniture, connecting to soft PU wrist and ankle cuffs via metal O-rings and clips.

Straps adjust up to roughly 95 inches with metal buckles to suit different bed sizes, making the set easy to install and just as easy to pack away discreetly.
