Quite simply, the best thing about this setup is once you've fitted it under your mattress, you never have to take it off. The way the straps work over the top of the mattress makes it easy to just unclip them and tuck everything away discreetly. This makes it much easier for any time you and your partner have the impulse to get into some restraint play. You simply bring the straps across the bed and clip them together, and you're set to go. Each "arm' on the cross has multiple D-rings, allowing for a better fit with people of differing limb lengths. Although, people who are taller may find it isn't quite enough to really stretch you out, (I'm 6'2 and my arms and legs end up bent) it still works well enough to hold you down. The velcro cuffs make it easy to fit most wrists and ankles, except those with very thin wrists or small hands. But if you've got a favourite set of cuffs with clips (let's face it, if you're buying this, you probably do) then you can just use those and clip them to the restraints. The velcro also makes it easy for quick release if necessary. A great addition to the bedroom, especially since it is so easy to use, easy to keep hidden, and great for breaking out at short notice.
