I wish I read the latest reviews before purchasing this chair, no wonder why it was so deeply discounted.  Upon opening the box, most of the parts were just rolling around the bottom.  Screws, button covers missing.  The plastic lever to adjust the height was broken in half.  Luckily the local hardware store had a matching screw so I could finish assembling.  Nothing worse than getting ready to assemble a product with missing parts.  Really disappointing purchase, I feel ripped off.
