Initially the device collapses into a somewhat portable state, allowing it to be stored under a standard bed.
But all it takes is a gentle lift to position the cushioned fulcrum to whatever height is required or desired.
Another angle shows the multiple straps used to secure me into it, preventing me from being able to move, voluntarily or involuntarily.
There are also very easy to click open or click shut restraints for the ankles.
Here you see the various notches which allow for the position to be raised or lowered. The metal clasps are there to quickly secure wrist cuffs.
A rear view showing the cushioned (pool noodle covering a dowel) fulcrum and the straps for my thighs. The ankle rests and restraints are also easily seen at the base.
I threw a pillow on it to give an idea of how it works. Imagine the pillow is me from shoulder to butt. My wrists would be secured to the clips in the lower right corner of the picture and my thighs immobilized by the straps you see below the pillow.
The entire thing is basically pine 2X4s , dowels, and smooth plywood. It is very sturdy. Its main drawback is that, while portable, it s a bit ungainly. Yes it can be set up by one person, but that person can't be a frail one. Also, as you can imagine, the victim can manage to help secure themselves with a number of the available restraints, but it does make it easier if the disciplinarian helps.
Once in my own body weight, secured to the already sturdy frame, makes escape and even movement impossible. The strap near the fulcrum alone does an amazing job to keep me still.
Admittedly this device is not needed for most spankings. But it is very good for special situations. I particularly welcome the immobilization if I'm going to be punished with the A&G "White Lightning" switch.
A pretty nasty synthetic "switch/cane".
Feel free to make one of your own......but please don't ask me for specs. The pictures show pretty clearly how simple this is and the dimensions for this one were tailored for me, and I'm 6'3". It's really just a 2X4 frame with a pivoting plywood platform. Also, I never bothered to stain or paint mine, but it could be something worth doing at some point. But if you really want a portable, yet sturdy restraint at a pretty low cost, this one is hard to beat.
