    1. Product Description

      Doin' the starfish has never been so easy (or enforced). With 2 bed loops that strap round the top and bottom of any double mattress and 4 adjustable cuffs, spread your lover's limbs for action that will give you full access and control of their pleasure.

      Made from ultra-strong Nylon straps with genuine leather cuffs, this full-body restraint set is durable and reliable for bondage that suits recreational and professional domination.

      Unlike many under-mattress restraint sets that sit under your entire mattress, we've kept things simple by making this one a 2-piece kit. Simply separate the 2 sections and fasten one around the top of your mattress, and the other around the bottom by lifting each end in turn. The easy-to-use pull straps enable you to adjust the overall size to fit your bed perfectly.

      Once the straps are in place, 4 leather cuffs easily attach to one of two metal O-rings in each corner via a sturdy carabiner clip.

      Putting away your restraint set is a doddle. Simply undo the seatbelt-style clasp to release each strap from your mattress and, hey-presto, you're done. Plus, this nifty design means you shouldn't need to adjust the straps for your bed again, making set up and take down seamless for each subsequent use.

      Collect the full DOMINIX range to add a professional standard to your BDSM play.

    1. A must-buy

      As with all Lovehoney products, this item arrived quickly and in discreet packaging.

      Being a beginner to bondage, this kit helped me gain confidence incredibly quickly. Not having to worry about things like ropework, the tightness of things or security made bondage a lot more fun than in the past.

      The spreader kit can be installed within minutes and is very very secure. The cuffs are high quality and feel amazing. Once clipped down, you fell totally immobilised.

      I do wish it came with more than four clips though as I've wasted time in crucial moments looking for one remaining clip. A few extra clips would help a lot.

      Overall, this kit has made bondage a lot easier and stress-free,

    1. Get out of that

      For years we've been using makeshift restraints, and I felt it was time to buy something more made for the job rather than having to mess around tying knots.

      Most of these products go underneath the mattress from top to bottom. While these products do work, it's possible for them to pull their feet and hands closer together, which can be a bit of a hindrance in the heat of the moment.

      This product changes all of that, with the straps going across the mattress rather than down the length of it. This forces them to stay in a starfish position. The extra set of D-rings to clip the cuffs onto is a nice touch, allowing you to go from wide, to wider.

      The biggest concern I had was the dainty size of my wife's wrists. She has a knack of being able to slide out of most things which are not Velcro. These, however, she stands no chance of. I had to do them up on the tightest setting for a firm grip around the wrists, but I could have most probably of got away with the second hole to last on the fastening strap.

      The only thing I was a little taken back by was the packaging, or lack of. The item came in a clear plastic bag. No box or printed graphics. With these restraints being on the higher end of the price bracket in comparison to the other products available, I would have thought they would have made a little more effort on the packaging. But! This is hardly an issue. Afterall, who sees the box again after it's been used.

      The quality of the product is fantastic. All of the stitching is heavy duty, so there's no concerns about broken threads with rough use and finding your new toy unravelling around the edges. The padding under the leather restraints finishes it off quite nicely. If you have used Velcro ones before now you will know how sore your wrists and ankles can become when used for a longer than normal duration.

      Yes, as others have mentioned, seeing the big black straps going around your mattress is not exactly covert, nor is it an attractive sight, but as always, where there's will there's a way. I fitted the straps to the mattress and made a couple of small incisions to the bed sheet to slip the D rings through, hiding the straps from view. Yes of course you can still feel the straps under the sheet, but with pillows across the top, and my feet rarely touching the end of the bed, this is a non-problem for us.

      Add a little kink to your relationship with this product!

    1. DOMINIX Delight

      Reviewed: January 28, 2016 by Shadow Collector

      Being a tester for Lovehoney has many perks - the free products, the chance to expand your horizons by trying something you wouldn’t normally go for, keeps your writing style sharp - but there are times when something will wow you beyond your expectations, beyond the thrill of being deemed good enough to test. For me, this moment was when I first opened up the plastic DOMINIX and tried on the leather cuffs that came with the set... and they fit!

      This sounds absolutely pathetic, right? Well, it’s not. I have never had a pair of cuffs fit me that weren’t cheap Velcro. Cursed with tiny wrists and ankles, I thought I would have to give up on ever wearing proper leather restraints with dignity and an inability to slide out of them like bangles. All those out there in the same boat rejoice, there is a solution after all!

      If the cuffs hadn’t already won me over, the restraint system itself would have done so in a heartbeat. I now own three under bed restraint kits, and this one was a welcome addition with its own advantages and disadvantages... Well, a lot more of the former if we’re being honest here.


      Unique Design - The kit is two separate straps that go around each end of your bed instead of underneath the mattress in the St Andrew’s cross style like most. This makes it so much easier to get in place, so spontaneous fun is a viable option.

      Choice of rings - Choose your spread: wide or wider! It’s nice to have some variety.

      Leather - The cuffs are lightly scented and comfortable, a perfect fit and beautifully made.

      Comfort - Thanks to the quality of build and the adjustable spread, I found it easier to spend long periods of time in this restraint when compared to my other two.

      Clips - As with every bondage situation, it’s very important to be able to get out of it quickly. The clips that secure the cuffs to the straps are secure enough that you’re not getting out easily... until you need to. Then, just flick the bar and you’re good to go (literally!)


      Double Bed Only - While the design can be tied creatively to fit a single, it’s not designed to do so. Other cross style restraint systems can be tightened to custom fit any style of mattress with no bother, but this one loses some of its charm if you do this.

      Bedroom Aesthetics - A silly point, some might argue, but there’s something so sexy about seeing somebody bound up without being able to see the restraints. Nothing to distract you from the scene, nothing to break the illusion. The way this is designed, there will always be a thick black line running across the head and foot of your bed. This is by no means a make-or-break point, but I had to fill out the disadvantages section somehow. Compared to the advantages, it looked so bare!

      Well, that’s it laid out as obviously and clearly as I can... heh.

      A quality, wonderful kit that should be a bondage staple for all. A special shout out for thin-wristed folks;This is the one for you! Leather, bondage and complete exposure team up to give us a sexy, sensational set that has become my firm favourite overnight.
