Well, I'm not 1.90 tall, I'm 1.86 m. but I've just raised it and I can certainly raise it another 10 cm. so I'd say it's suitable for 1.90 too. You can't raise the backrest individually, but I think it's big enough. The armrests can also be set very high. = I would say it is not a problem for 1.90. The chair is very good. Also not susceptible to dirt etc.
