### Why You'll Love It

Steel chains are what separate DarkSpread from every fabric bed restraint on the market. They don't stretch, they don't give, and they don't slowly work loose over a session the way webbing does. Six of them run from the under-bed system to the cuffs, holding firm and holding still — and the sound they make is half the appeal.

The system itself disappears. A long strap runs beneath the mattress with attachment points emerging at all four corners, so a king bed becomes a four-point restraint frame with nothing drilled, nothing mounted, and nothing visible once the sheets go back on. Installation takes no tools.

Clip the handcuffs and ankle cuffs to the D-rings and the spread-eagle position is set — arms and legs stretched, nothing left to negotiate. The waist cuff is the piece most kits skip: a reinforced hex structure that restrains the core and limits the movement that four-point restraint alone still allows. It adjusts across all body shapes.

Then the other seven pieces build the scene. Collar and leash for dominance, ball gag and blindfold to take speech and sight, nipple clamps and the whip and feather tickler for sensation, and an anal plug for simultaneous stimulation. Every element combines freely, so the configuration changes with the night.

The materials are soft and flexible against the skin, and the steel is smooth and rust-resistant rather than sharp — firm restraint without scratching. Everything is waterproof and wipes clean in seconds.

### How to Use

Place the long strap under the mattress so the attachment points emerge at all four corners of the bed. No tools are needed.

Fasten the handcuffs and ankle cuffs and clip them to the D-rings using the steel chains, securing your partner in a spread-eagle position. Add the waist cuff for core restraint.

Adjust the buckles and sliders on every strap until the fit is secure and comfortable.

Add the collar and leash, ball gag, and blindfold as the scene calls for, and use the nipple clamps, whip, feather tickler, and anal plug for sensation. Release the buckles when you're finished.

### Care Instructions

Wipe the waterproof pieces clean with toy cleaner or mild soap. For the fabric straps, hand wash in cool water with mild detergent, squeeze out excess water, and air dry in the shade. Avoid bleach, ironing, and machine washing.
