What a sight that would be to offer your client a normal seat, then sit yourself in the tank chair, saying “Let’s talk about your website, how do you feel about ____?”

But really, a quality chair makes such a difference. I splurged on a “24-hr rated” type and there is just no comparison to the cheapies. Between a good chair and using a tablet, I experience basically no aches and pains from my 8+ hours at a desk each day.
