When I first opened it, I just saw a mess of straps and cuffs and couldn't tell heads from tails, but after my partner and I unfolded it and laid it out on the bed we could see that the design couldn't be clearer. The UBRS comes with four cuffs and a strap system that is set up under the mattress for the cuffs to attach to. Imagine two Y's joined by their bottoms, or perhaps an H; this is the shape of the system. A main strap runs lengthwise down a portion of the center of the bed under the mattress, and at each end of this strap are two more straps that are attached by a ring. These four straps have detachable cuffs on their ends, and are the only parts that stick out from under the mattress. If this sounds confusing, worry not! There's a nifty diagram on the back of the box that will clear everything up pretty quick.

My absolute favorite aspect of this system is the variability and adaptability of it. I really can't stress enough how cool this is, and even if I detail all the things I've done with it, I'm sure a more creative couple will come up with something new. Every length of strap is easily adjusted, so in addition to fitting to any standard sized bed, you can choose how tightly bonded or vulnerable you want to be. The system can be arranged so that the restraints come out of the side of the bed for a spread eagle position, from the top and bottom of the bed for a stretched out position, or any combination thereof such as arms above the head with the legs spread, or vice versa. If the system is set up to have the restraints coming out of the side of the bed, one set of appendages can be released without giving the other set slack. For example, the legs can be released and the bound partner still won't be going anywhere... unless you count their legs which will be up in the air.

The detachable cuffs also allow a lot of creativity and can be used on their own without the bed restraint system and/or in conjunction with other toys. I like to bind my partner's arms with the restraint system, then use the leg cuffs with a three foot spreader bar to keep them forced apart while allowing them to be up in the air. The cuffs will, however, shed little bits of black fuzz all over the place for the first use or two, but after the excess material has been worn off the soft material is exquisite.

I was a bit concerned that the straps might not be able to restrain my large muscular arms (ok... maybe not so much) without breaking during the throes of passion, but I found that the corners of the mattress would be pulled up instead. Of course, whether this is standard or not depends on the rigidity of your mattress, but I liked that the restraints had a little give when I pulled hard.

On the topic of discretion, the restraint system can be tucked back under the mattress to hide, which is great because whenever you want it, all you have to do is reach under the corners of the bed and pull out the cuffs. If the restraints can't be left under the mattress for whatever reason, it's very simple to set up and take down, so doing so before a session isn't a big deal.

My partner and I absolutely love this thing, and it has become a regular customer in our bedroom shenanigans. I highly recommend this as an addition to any bed that sees any amount of bondage.
