Hi Everyone.

New to the forum

I am attempting to design a piece of furniture that has opposing forces. A set of opposing stairs that either lower or raise a central platform. The idea is that two people would have to collaborate together to make sure the central platform doesn't sink. Think of it as a pyramid with a flat top (this being the platform) with stairs either side. Currently I understand that a pulley system could be used to raise the platform once a stair is stepped on. But how might I achieve downward force with both a stair and the platform?

Bit weird I know. But perhaps fun to explore.

Welcome to PF!

Can you draw a picture of this? I'm having trouble picturing it.
