Besides being very easy to assemble, this chair is stylish, well-built, rugged and, above all, extremely comfortable.  Neither my wife or I realized that the arms lift up and out of the way (just like an airline seat).  This feature is wonderful and makes it so much easier to slide in an out of the chair. The 5 wheels roll on carpet much easier than the 4-wheel chair we replaced.  The height adjustment works whether you're sitting on the chair or standing next to it.  The chair we replaced had a terrible height adjustment and frequently collapsed under my weight. I wish it came in colors.  I have a need for a red and blue version.
