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.
Head rest height is fixed so it digs into the shoulders of a tall person. Removed the head rest hence a four star rating. If the height was adjustable I would have given a five star rating.
This is the most comfortable computer chair I have had in years. I have short legs and I can sit way back and still have my feet on the floor. Comfortable back support. Wish I would have found it years ago. I would recommend this to anyone
