Sapetti's "chairless chair" idea is a different kind of take on the exoskeleton idea. I've seen this idea before - but I still like it.
(Sapetti's chairless chair exoskeleton)
The Chairless Chair is designed primarily for manufacturing environments, where workers are required to stand for long periods of time and where traditional chairs would be an obstacle.
The wearable exoskeleton allows users to walk around freely but have instant support once they get into a bending, squatting or crouching position.
Before the idea of an exoskeleton was ever imagined, one finds this precursor from "A Conquest of Two Worlds", by Edmond Hamilton, published by Wonder Stories in 1932.
Earth's scientists solved the problem to some extent by devising rigid metallic clothing not unlike armor which would support the interior human structure against Jupiter's pull...
"Their greatest obstacle was not the Jovians themselves, who could offer no effective resistance to the atom-blasts and bombs of Crane's men, but the terrible Jovian gravity that made each movement an effort, that required them to wear the metal body-support armor and made their movements still more difficult..."

I'll bet you'll enjoy reading about one of these similar inventions:
