Feel like taking the (sex) fun on the road? Or maybe you'd rather keep your erotic adventures close to home. In either case, Sei Mio's The Bed-Spreader Under Mattress Restraint Set is more than happy to help!  

Whatever position(s) you have in mind, there's a Bed-Spreader configuration to match. Once you've slipped the straps under your mattress (they're attached to a sturdy center ring), pull out the four ends, clip on the cuffs, and adjust the length—generally, the shorter the strap, the further apart their limbs will be.

The four super-soft standalone Cuffs hook up to the Bed-Spreader with rugged swivel hardware; they're size-adjustable (the fastenings are velcro) and work with tons of other gear, too.

The Bed-Spreader's straps adjust to fit any standard bed. Hand wash as needed.
