I know, right?! I mean who needs chairs. They've been in use forever and yet not a single double blinded study, nevermind one which shows benefits.

Funny that you would bring up chairs. Originally, other pieces of furniture were used for sitting.

The chair has been used since antiquity, although for many centuries it was a symbolic article of state and dignity rather than an article for ordinary use.[1]
