Review on Hercules Series 24/7 Intensive Use Big & Tall 500 lb. Rated Black Mesh Executive Ergonomic Office Chair with Adjustable Ratchet Back - Flash Furniture by Aries Gregg

I had such high hopes for this chair. My first clue that something was going to go wrong was when a random little screw fell out of the chair and I couldn't find where to screw it back in. Assembled the chair very well only to find that the adjustment for the back of the chair (to raise the mesh up and down as needed for lumbar support) did not work. I suspect that this is where the little screw escaped. Then the tilting mechanism didn't work at all. I called customer service and they offered to send a new chair, but the box was in bad shape and after I built the damn thing it was almost impossible to repackage. They promised to send a new tilt mechanism and rear end, but they never came. Called support again, same story. A few weeks later, the left arm continued to wobble and tilt into an uncomfortable position. So every day I tightened the hex bolt and by the end of the 8 hour work day it was loosening. I've overtightened it too many times and the hex has frozen so it's now permanently skewed widthwise. Then pain in the coccyx. Oh my god, that got pretty uncomfortable after a while - so much for heavy use. And maybe because I don't have a recline adjuster, I sit very far forward and put extra pressure on my tailbone. I've tried experimenting with the height by adding pillows etc but it seems to be getting worse. Maybe if this lumbar support adjustment feature worked. If you want to spend almost $200 on a chair that you don't want to sit in for long and doesn't bother with anything other than pneumatic height adjustment, then this is the chair. To you. If you want all the features it claims to have, look elsewhere.
