Loving this chair. My wife and I were both previously using the Tempur-Pedic TP9000 chair. I'd been using mine for probably 6 or 7 years. Those were awesome chairs. The mechanism in my wife's started to wobble, though, so I decided to look for a replacement. Honestly I think it was a factory defect because hers was only a year old...but it was still too late to try dealing with any kind of warranty. I remembered seeing a review for Noblechairs on YouTube (specifically by KitGuru Tech) and decided to look in to it.After reading and watching dozens more reviews, and consistently hearing about the outstanding quality, I decided to buy one. I chose the Hero specifically due to the more comfortable size and less prominent bolstering (my wife likes to sit cross-legged in the chair sometimes, so I wanted to make sure she would still have room to do so). Spoiler alert - I ended up liking the chair so much that after getting my wife one I also ordered one for myself.Delivery was way faster than originally advertised, so that was nice. Once it arrived, I immediately ripped open the packaging and got to work assembling it. My wife helped put it together, but the task can easily be done by a single person. All of the components were in perfect condition and appeared to be high quality (and heavy). I really like the mechanism for this chair (the part that connects the bottom of the seat to the hydraulic cylinder). Normally, that is the part of a chair that fails after enough use. The mechanism on this chair, however, appears to be very durable.The chair is rated for up to 330 lbs and it definitely feels like it. Everything about it is solid. The only part of the chair with play to it is the arm rests, which can be jiggled a bit. I'm not sure that it's avoidable to have at least a little jiggle to adjustable arm rests in an office chair, so I don't hold this against them. When resting my elbows on them they don't move. I do agree with another reviewer who stated that the quality of the material on the arm rests leaves a bit to be desired. Perhaps some kind of padding would be nice, but they're fine as is so I'm not dwelling on it.The recessed plastic edges near the buttons you press to adjust the lateral position of the arm rests is a bit sharp. I should be able to fix that in about 10 seconds with sanding paper, but I really feel like that should be caught in QA. Again, not a big deal. If I'm buying a nice chair and that's the only complaint I can come up with, then I consider it a good chair.The adjustment controls feel great. Reclining is solid and smooth. Tilting backwards feels great, and the amount of resistance can be adjusted with a knob on the bottom of the mechanism. The lower-back adjustment feels present but mostly insignificant - maybe it's just the way I sit.The padding feels excellent. It's a bit on the firm side, but that's what I want. This chair does not feel like it's going to go flat after a couple years of use. I don't know much about this "cold formed foam" or whatever process they use, but it feels amazing. The shape is nice and supportive (I'm about 6'1"). The pillows are nice, too, but I only really use the one for my neck. The second pillow, intended for lower back support, doesn't feel very comfortable so I don't use it.Overall this is an amazing chair and I'm happy with the purchase, provided that they last for years and years (spending almost $900 for a pair of computer chairs is not something I want to do frequently). If anything changes I'll update the review.
