A standing cage made entirely of thick, durable rubber straps that works like a finger trap. Your partner steps onto the solid wooden platform, and their own weight draws the crisscrossed straps down and tight around them.
The straps spiral up around the body and meet at a sturdy metal ring at the top, which hangs from a suspension point. Once inside, your partner is held snug and at your mercy, able to wriggle but not to slip out.
