This is by far the best chair I've ever had!! I am plus-size and this chair is so comfortable!! The arm rests go up and down completely out of the way. The chair tilts back and forth or locks in place if wanted. This is a wonderful chair and I am very happy with this purchase!! Highly recommended for anyone who works at home full-time and sits 8 hours a day!
The chair was pretty easy to set up. The only hint I would give to other purchasers is that when you put together do not tighten all the bolts till the end. If you tighten first you will have a hard time installing the back. The chair is sturdy and feels pretty good. it does not allow you to set tilt so you are very upright until you lean to get the right angle. The armrests are only flip up and not adjustable that is why I did not give it 5 stars.
