    Rated 4.4 out of 5�by 369 reviewers.
    Rated 5 out of 5�by Great ergonomic chair I have had this chair for my office for almost 2 years and decided to buy one for my home office. I love the chair! It's very comfortable to sit in for long periods of time. I like the mesh bottom that also allows for complete air circulation. August 25, 2015
    Rated 4 out of 5�by great chair I wanted the chair that has cushion seat-was not in stock,so I settled for mesh seat, was a little expensive, but after a month or so still not unhappy. August 24, 2015
    Rated 5 out of 5�by Great Chair This office chair is wonderful for sitting comfortably for long periods. The mesh design makes it so I don't get too uncomfortable. The adjustability is an absolute plus. Once I had it adjusted the sitting was so much easier to get office and sewing work done. I am very happy with this purchase. August 24, 2015
    Rated 2 out of 5�by Nice chair except for limited tilt angle There are three positions for the tilt angle of the back. It goes from too far forward, to too far back, to WAY too far back (like you're trying to take a nap). Not able to get comfortable. The tilt angle options should be set closer together and skip the major recline so that one of settings is just right. I am trying to avoid the back pains I get in most chairs, my impossible search continues. August 22, 2015
