i am not very good at describing but there was one thing my ex and i had that we could store away..

It was a kneeling/whipping post ..

Description:

a peice of plywood 4ft. length x 3ft. width that had a 6"x6" beam that was about 3.4 ft. length.. on the inside of the 6x6 there was a hinge that would allow the beam to fold down for storage and two flat eye hooks on the other side of the beam on each outer edge that matched up you two in the board that kept the post up when in use .. They were held together by 2 cauter pins.. On each side of the 6x6 beam at the top were two larger eye hooks that cuffs could be easily attached too.. and two more U hooks on the far end of the board for cuffs to be tied to for her ankles... Sometimes if he wanted me well spread he attached a spreader bar..

You could also add two more U hooks on each side on the board upfront close to the post but on the edges again to have her knees well spread .. just a suggestion..

Hope this helps
