Using the Sportsheets Under The Bed Restraint Kit is easy. First, place the restraint kit under your mattress without the need for hooks. Adjust it to the size you want. Then, use the 4 adjustable cuffs to secure your partner's wrists (which fit wrists from 4 - 12 inches). The 4 restraint straps, connected by one connector strap, will keep your partner's arms and legs in place. When using, make sure your partner is comfortable and agrees to it. After use, simply clean the cuffs and straps with a damp cloth and store it in a dry place. It's important to handle the product gently to ensure its long - term use. Enjoy your special moments with this fun and portable product.
