in all honesty Pharkus the best chair both ergonomically and comfort wise is the Herman Miller Aeron chair. its amazing comfortable and you can park your ass on one for days on end. theyre used extensively in the animation studios like Pixar for this very reason
they look awesome too!
the chair i use at home is a Wilkhahn Modus
i bought it for its simple German design. like the Aeron chair is amazingly comfortable and i can spend hours in it with no aches what so ever. same cant be said about my shitty work chair.
the plastic parts are apparently made in the same factory that Porsche use.
when you consider driving is totally different from sitting in front of a desk you have to realise that a car chair and office chair are different.
would you really want to spend hours sitting in a chair with high bolsters pushing your thighs together getting all sweaty with restricted lateral movement?
