First off, I would like to say that I was shocked at how fast this chair was shipped to me. I ordered it in the afternoon and it was shipped to me by the next afternoon, roughly 24 hours later. I have Amazon Prime membership which is 2 day free shipping. Most products I order from Amazon don't arrive overnight like this 50 pound package. Very impressive.The shipping box came dinged up but most of the contents were unharmed. Only a plastic cover piece on the bottom of the chair was chipped during shipping and the arm rests were a bit dirty.The assembly was simple, although the instructions weren't very thorough nor detailed. It took me about 20 minutes to unbox it, unpack it, lay out all of the pieces, and put the chair together. These chairs are made in Taiwan so the materials seem very sturdy and of good quality. Only the arm rests are a bit loose and not as sturdy as the rest of the chair, but they're able to serve its purpose. I also question how durable the mesh material on the backrest will be, although there are no signs it will fail to support my back.This chair comes with a lot of adjustable parts. Arm rests are height adjustable (won't swivel like more expensive $500+ chairs). You can adjust the seat height obviously. What makes this chair stand out from others around this price range is the fact that you can adjust the tilt of both the seat and backrest. The 2 levers behind the height adjustment lever is for the recline of the seat and the backrest. You push the levers all the way down to lock it in the position desired. You pull them up to unlock it, turning this chair into a recliner.Keep in mind, this model number is 86200, not the older 86000 or newer 86205. I think the only difference between this model and the more expensive 205 version is that the 205 model has a tilt tension adjustment knob under the seat, while the 200 version doesn't. I believe the knob is to adjust the tilt tension of the seat based on your body weight. Not a big deal in my opinion.Like a lot office chairs, out of the box brand new, this chair feels amazing. It's very comfortable with tons of adjustments. Overall, this was a great purchase and for under $200 (regular price is ~$170, on sale ~$150), it's an amazing deal. It'll be tough to find anything similar at your local Office Depot / Max or Staples. I think it's a worthwhile investment for those that want a comfortable, high quality office chair, but can't spend $400 or more. I might give an update to how the chair holds up a year or two later...
