"I've purchased a half dozen "intensive use" chairs and worn each out after 3-5 years max. This one (3150hr) seems better built than any of them. The red fabric..has a really high-end look and almost glowing?? effect to it. Reasonably fast ship...and great communication about order status. It was super easy to assemble, but required wrench to attach seat back to seat and that step wasn't in the instructions for some reason...maybe the way mine was shipped in two pieces isn't always the way it comes. It was very stiff at first, which is a good sign it won't break down quickly...and within about a week it was already quite comfortable. It has just enough adjustments to be a fully ergonomic office chair. I'm 6'3", 260lbs and it fits me very well. I had ordered rollerblade style casters on amazon...but the casters it comes with were actually way better on carpet despite looking like old school casters. I highly recommend the chair...it's expensive, several hundred more than the chairs I purchased previously, but I don't think I'll have to replace this one in my life time, certainly not in just a couple of years."

"Excellent service. Driver could not find our suite number and customer support contacted me right away to assist. Product arrived in very good condition. Magnets are super strong. Very effective "sneeze guards.""

"The 9to5 Seating High-Back Mesh Chair is a really great product. It was very easy to assemble. The seat is very comfortable as is the mesh back. I highly recommend this product for home office use."

"The team at Advanced Ergonomic Concepts always do a wonderful job in getting my operations squared away with seating and accessories. Customer service is superb and the shipping is fast. The quality of seating is outstanding and makes all the difference to 27/7 operation such as ours."

"This company, and specifically employee Kayla Puckett provided my company EXCELLENT customer service. We had an issue with one of our orders and when I emailed Kayla about it, she responded very quickly with exactly the right solution and just really impressed me with her attitude and problem solving. It is exactly this type of situation where a company and their great employees can turn an unhappy customer into a customer for life. Kayla is to be commended - as is the company culture that empowers her to do her job so well. Kudos!!!"
