This under-bed restraint system turns almost any bed into a four-point tie-down in about a minute, no headboard, drilling, or hardware required. The H-shaped strap slides under the mattress and the weight of the bed holds everything in place, so you cuff both wrists and both ankles and your partner stays put until you say otherwise.

Features

• H-shaped center strap tucks under the mattress and anchors all four corners
• Fur-lined cuffs that close with heavy-duty Velcro, soft against the skin
• Adjustable buckle on every strap so you can pull things as snug or as loose as you want
• Straps extend to roughly 48 inches each; cuffs open to about 14 inches around
• Packs flat, so it stores in a nightstand drawer or goes in a bag for travel

Materials and care

Nylon webbing, fabric straps, plastic buckles, and faux fur cuffs. Spot clean the cuffs with a little mild soap and water, then let them air dry. Keep them out of the washing machine.

Worth knowing

The cuffs close with Velcro, not locks, so this is a great starter set for light, trusting play. A determined partner can work free if they really try, so it is not meant for heavy escape-proof bondage. It fits most standard mattresses, but a very thick pillow-top can eat into the usable strap length. Everything ships in plain packaging with a discreet billing descriptor, so no one but you knows what showed up.

FAQ

Do I need a headboard or bed frame?

No. The H-strap runs under the whole mattress and the bed's own weight holds it, so it works on platform beds, box springs, and frames without rails.

Will it fit my bed?

It fits most standard mattress sizes from twin up to king since the straps adjust to about 48 inches. Only an unusually thick or oversized mattress would be a stretch.

Is this good for beginners?

Yes. The fur-lined cuffs are comfortable, the Velcro is easy to get on and off fast, and nothing locks, which makes it an easy, low-pressure way to try restraint play.
