Ergohuman Eurotech ME7ERG GEN2 High Back Mesh Office Chair with Tilt Tension Control, Tilt Lock, Back Angle, Back Height, Synchro Tilt, Seat Height, Seat Depth, and Arm Height Adjustments, Grey

I purchased this chair in May of 2012. As someone who works from home at a PC for untold hours each month, the investment has been more than justified by the comfort and adjustability of this chair. I did encounter a significant failure but it was immediately remedied by the Eurotech company, as explained below!I am 6'2" and I find that it raises just high enough -- both height from the ground and height from seat to headrest. The mesh material is shockingly durable...I've been in this chair for thousands of hours and it has yet to show any signs of wear (3 years x 300 days (conservatively) x 6 hours per day (conservatively) = 5400). Rather amazing.Another reviewer mentioned that they'd prefer the seat to tilt up and down. I totally agree. That would alleviate stress points for many people, though personally I've made it irrelevant by purchasing a 'Geek Desk' which raises from a sitting to a standing height. I also wish that the lumbar support was more aggressive...for the past few years I've had an additional lumbar pillow on the chair, which causes me zero difficulty and results in a near-perfect sitting experience.The real reason I'm leaving this review is to praise Eurotech's warranty and customer service. After a crazy amount of using this chair, I one day found that it was locked all the way 'back', which is to say that I could not tilt it forward. I tried everything I could think of...tightening/loosening bolts, using WD-40 on key joints, etc. etc. Ultimately, I filled out a simple form with Eurotech including a PDF file of my original purchase. Within 10 hours a representative replied and said that no, I couldn't service it myself (as I'd hoped), but that yes, they would replace it.I needed a new 'Seat and Mech' in their parlance, which meant literally an entire new mesh seat with all of the attached mechanisms...it probably weighed 20 pounds, accounted for 1/3 to 1/2 the price of the entire chair's design, and yet they shipped it to me in a few days with ZERO cost for S&H or anything else. Truly an unparalleled customer-service experience.I bought this product with a 'Lifetime Warranty', it broke, and they fulfilled the warranty once I proved my original purchase. It shouldn't be revolutionary, but I've gotta say...it was a refreshing experience to get a brand new piece of pricy equipment with virtually no hoops to jump through.I could comment on every single aspect of this chair, so if you have a burning question please leave it below and I'll reply.All in all, I love this product and am even more enamored with their customer service.

I have tried several different chairs including the Herman Miller Aeron chair and out of them all this is by far the most comfortable one I have used. I have a ruptured disc between L4-L5 and this is the only office chair that I have found so far that allows me to work a full 8+ hour day without having back pain. I don't like to spend this sort of money on a chair but in the end I'm very glad that I did. If you have lower back problems I highly recommend this chair.UPDATE. I have now been using this chair for about 1 year and 3 months and I've had ZERO problems with this chair and I'm still every bit as happy with it today as I was the day I wrote my original review. I still think the price is a bit high for an office chair, but it seems that is the norm these days. The ergonomics of this chair are excellent, the mesh keeps you cool all day and it still looks good as new. Even with the high price I highly recommend this chair, for me it was an excellent purchase!UPDATE: I've now been using this chair daily for 10-14 hours per day (small business owner) for over 5 years and I'm still just as happy with it as I was the day I bought it. Nothing is broken, nothing has worn out, it's still think it's very comfortable and although it's starting to show signs of use (mostly just scratches from me being careless) it still looks great. Due to expansion of my business, I'm now in the market for more office chairs and for my personal office chair I'm buying another one of these chairs. I actually wanted to buy the newer updated Ergo Elite Chair because the arms are adjustable width wise which these are not, and the arms tilt with the back and these do not, but the Elite is not as wide as the original so I'm sticking with the original.UPDATE: Nearly 10 years of daily use and still no problems.
