By most accounts, the first stairlift was used by Henry VIII of England in the mid 1500s. It was really more of a “stairthrone,” used to get the overweight king up and down the steps of Whitehall Palace in London.
For much of his life, Henry was quite athletic. But when he was 44, he suffered a serious leg injury while jousting. His health began to decline, while his weight increased. By the time Henry was in his 50s, he had a 52 inch waist (according to records of his armor).
