A Question about Chairs

Alright, this is kind of a strange question, but hear me out; I’ve had a lot more time to work on art and animation as of late, but my back has been killing me on account of my leaning forward to use my drawing tablet. If anyone here does this sort of thing for long periods of time, do you have a specific type of chair you would recommend?

(granted I’m pretty sure the issue could probably be solved by fixing my posture, but I’m curious to see what kinds of chairs others use)
