Was easy to assembly (took about 20 minutes) and so far is comfortable and everything works as it should. My wife needed a chair with a shallower seat as our other executive type chair was too deep for her at 5'-2". This one fits her much better. Hopefully it holds up for years to come!
Summary: Excellent ergonomic office chair at a value price. The Red/Maroon model looks nice and stylish. Relatively easy to assemble much easier with two people to hold and stabilize while assembling the heavier parts of the chair but does not require special tools. Comfortable and adjustable for ergonomic support - only thing I couldn't figure out was how to rotate the arms. The lumbar support doesn't lock easily in place but still supports the back well.
So comfortable for my back. The size of the chair is great for short people. Love the head rest and being able to recline when I need to relax and stretch.
I've used this chair almost daily for a year now. The armrests split at the sides and front a few months ago. The chair is mostly fine - comfortable and enough adjustments to fit most people. But I question the quality and longevity. The chair this one replaced lasted me 8 years and I didn't have any of the quality problems I'm having with this one. Would not reccomend.
