I am tall, 6 foot 2 inches, my desk chair is the most comfortable seat for me in the house. I have it all the way up, it makes it a lot easier for me to get up out of it.

I don`t do couches now, they all seem way too low for me. My next desk chair will probably have an adjustable back on it too if I can find one like that. I need support to sit up straight.
