This under-bed restraint kit turns almost any bed into a four-point tie-down in about a minute, with no hardware and no headboard needed. The whole rig slides under the mattress, so the bedroom looks completely normal once you pack it away.

Features

• Four padded cuffs for both wrists and ankles, lined so skin doesn't chafe when a session runs long
• Adjustable, locking buckles that fit most wrist and ankle sizes
• Center strap runs under the mattress; corner straps adjust to fit twin through king
• Sets up and breaks down fast, then stores flat in a drawer
• Color: black
• Ships in plain packaging with a discreet billing descriptor

Materials and care: nylon webbing straps, soft padded cuffs, and metal buckles. Spot clean the cuffs with a damp cloth and mild soap, air dry fully, and keep the webbing out of direct sun.

Honest note: the buckles lock, but these aren't steel manacles. A determined person can still work loose, so treat this as restraint for play, not real security. The padding is comfortable rather than plush, and very petite or very large frames will sit near the ends of the adjustment range.

FAQ

Will it fit my bed?

Yes. The straps adjust for twin, full, queen, and king mattresses. The center strap runs under the mattress and the four cuffs pull up at the corners.

Does it need a headboard or any tools?

No. Nothing bolts to the frame and there's no assembly. Slide it under the mattress and you're set.

Is it comfortable for longer sessions?

The cuffs are padded to cut down on chafing and pressure, so wrists and ankles hold up better than with bare straps. Check circulation now and then and loosen anything that feels tight.
