This is a strong, entry-level bondage kit, that will hold your partner in place. Easy Velcro cuffs quickly lock the comfortable wraps around the wrists and ankles. We use a queen-size bed and there seems to be plenty of length on the straps. We are able to anchor the straps under the bed, to the middle support bracket of the bed, although this is not necessary. I recommend this product to both beginners and advanced users. These straps seem to hold up as much tension as your mattress can take from you pulling on it.

These are very comfortable cuffs, and easy to use in the heat of the moment. A fantastic product that is able to hold up to some decent tugging and struggling. From missionary to doggy-style, you can find many ways to use this system. I just love how it is hidden, but not out of reach! This product should be able to fit a king-size bed, but I am not sure if you will be able to get into the doggy-style position. Then again, our system runs under the bed. You can save a couple feet by installing the system between the box spring and mattress.

This unit will hold you in place. The cuffs are manageable with the quick-release/attach Velcro. The straps are definitely long enough for our queen-size bed. We are able to wrap the straps from under the bed and easily hide the cuffs without anyone ever knowing they are there. Strong and ready to go!

This is a hidden restraint system. We hide it at the 4 corners of the bed. Other beds may need to hide them directly under the mattress, but this is still quite easy to manage. Maintenance-free. The straps are just waiting to be used, and the plastic adjustment clips are easy to use, as well.

Basic instructions were provided on the back of the package. They gave the basic information necessary to install the product and use. The system came in a basic clam-shell. I have found a video of installation at You Tube.

We enjoy this system from time to time. It is a nice way to add variety in the bedroom!

Right before orgasm, pull REALLY hard on the restraints. This will add to the orgasm due to the tensed muscles. The relaxation feeling afterward is incredible!
