Very nice chair! I like it and use it a lot. The only thing is the headrest doesn't adjust high enough for me. I'm 6 foot tall and in order to take advantage of the headrest I have to slide down in the chair a little. But otherwise this seems to be a well built chair well packaged and easy to put together. I'm very pleased with my purchase and with my chair! By the way a friend recommended this and I'm glad she did she has one too.
Don't bother installing headrest as it is way too low for an adult. Found a website hack that tells you how to install it several inches higher up. Not recommended by manufacturer but it makes the chair into a five star
I can sit in this chair for a long time but every time I move and my heads not on the headrest the headrest will fall down into the lowest height position and I have to reposition it which gives this a star less!
