bit pricey, but ive been enjoying it. only real issue i have is if you like to have your legs spread out like I do, the bucket seat is firm so your legs will rub against the sides. but overall I'd def recommend it for people trying to keep the back straight.
I just got this one, and I really like it! [link]
However if you have really broad shoulders, it would encourage a rounded shoulder position. It works for me because I am a petite woman (not short but my frame is slight), so my shoulders end where the chair starts to curve. And the lumbar support is adjustable, which my back really likes. I need a footstool though, the chair doesn't lower enough lol. I picked this one because all the other adjustable lumbar support chairs I could find were all sold out!
