All furniture commodes cars etc.are designed for short 5 feet tall people?

I am 59M but I am 5 feet 11 inches tall. I find that all standard chairs tables sofas beds commodes cars are designed for short 5 feet people as they form majority per cent of population here in MH. Offcourse I can get a custom designed furniture for my home but when I am at public place all the things are designed for 5 feet people which creates stress on my knees hips and back . Please share your opinion on this issue.
